To assess the use of cervical mucus monitoring (CMM) in women trying to conceive and determine whether monitoring is associated with increased cycle-specific probability of conception (fecundability). Time-to-pregnancy cohort study. Population-based cohort. PATIENT(S): Three hundred thirty-one women trying to conceive, ages 30 to 44 years, without known infertility. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): CMM prevalence and fecundability. RESULT(S): During the first cycle of the study, CMM was performed consistently (checked on >66% of pertinent cycle days) by 20 women (6%), inconsistently (34% to 66% of days) by 60 women (18%), infrequently (≤33% of days) by 73 women (22%), and not performed by 178 women (54%). Cycles in which CMM was consistently performed were statistically significantly more likely to result in conception after adjusting for age, race, previous pregnancy, body mass index, intercourse frequency, and urinary luteinizing hormone (LH) monitoring. Fecundability also increased with increasing consistency of CMM. CONCLUSION(S): Among women trying to conceive, CMM is uncommon, but our study suggests that CMM-a free, self-directed method to determine the fertile window-is associated with increased fecundability independent of intercourse frequency or use of urinary LH monitoring.

Combined oral contraceptives (COCs) are considered for their thrombogenicity and the risk of premature atherosclerosis and the stroke caused by them. The aim of this study was to evaluate the relationship between chronic use of low-dose COCs (ethinyl estradiol 30 mcg + levonorgestrel 150 mcg) and endothelial dysfunction and intima-media thickness. In a cross-sectional study, in 2011-2012, 60 healthy premenopausal women (30 cases of COC consumers and 30 controls as nonconsumers), aged between 25 and 45 years, participated in this study. They were current users for at least a 3-year period. Brachial artery flow-mediated dilatation (FMD) and common carotid artery intima-media thickness (CCA-IMT) were measured for the patients. The mean duration of COC consumption was 54.03 ± 27.27 months in the case group. There was a significant FMD% difference between 2 11 ± 3.53 versus 15.80 ± 9.22 (P = .01). In addition, a significant mean CCA-IMT thickness .53 ± .07 versus .44 ± .08 (P = .00). However, after multiple regression analysis and adjusting for body mass index (BMI), in COC users, no significant association between COC consumption duration and FMD% and mean CCA-IMT was observed. Prolonged used of low-dose COCs may cause changes in both endothelial function (measured by FMD%) and endothelial structure (measured by CCA-IMT). There was a nonsignificant inverse relationship between the duration of COC ingestion and FMD% and a nonsignificant positive relationship with CCA-IMT. Our results are in favor of early atherosclerotic changes in prolonged users of COCs.
Does unilateral volume-adjusted laparoscopic diathermy increase the chances of ovulation in women with polycystic ovary syndrome (PCOS)? Although unilateral laparoscopic ovarian drilling (ULOD) using adjusted thermal doses was more efficient than bilateral laparoscopic ovarian drilling (BLOD) using fixed doses, the chances of ovulation were improved in patients irrespective of the technique used. The adjustment of the thermal dose to ovarian volume in BLOD increases ovulation and pregnancy rates compared with fixed-dose treatment, but BLOD causes the formation of adhesions, particularly on the left ovary, and increases the risk of damage to ovarian tissue. In contrast, ULOD with a fixed thermal dose minimizes the risk of ovarian tissue damage, and can increase the activity in both right and left ovaries, although this varies in humans and in other species. STUDY DESIGN, SIZE, This prospective, longitudinal, study, between September 2009 and January 2013, included 96 infertile women with PCOS who were unresponsive to clomiphene citrate treatment and had underwent either ULOD or BLOD. After surgery, the groups were followed up for 6 months to assess ovulatory response. PARTICIPANTS/MATERIALS, SETTING, Patients were assigned to two groups; one group underwent laparoscopic ovarian drilling of the right ovary alone, while both ovaries were treated in the second group. The ULOD group (n = 49) received thermal doses adjusted to the volume of the right ovary (60 J/cm³). The BLOD group (n = 47) received fixed doses of 600 J per ovary, regardless of its volume. The two treatment groups were matched by the number of participants, age and baseline parameters. MAIN The ovulation rate during the first menstrual cycle after LOD was significantly higher in the ULOD group than in the BLOD group [73 versus 49%; absolute risk reduction (ARR), -0.25; 95% confidence interval (CI), -0.44 to -0.03; P = 0.014]. Treatment with ULOD on the right ovary significantly increased the chances of ovulation in patients with a larger right ovary compared with those who had a smaller right ovary (100 versus 36%; ARR, -0.64; 95% CI, -0.84 to -0.37; P = 0.004). Interestingly, the chances of ovulation were also significantly higher in patients in the BLOD group who had a larger right ovary compared with those who had a smaller right ovary (88 versus 33%; ARR, -0.55; 95% CI, -0.73 to -0.28; P = 0.002). The pregnancy rate was also significantly higher in patients with a larger right ovary compared with those with a smaller right ovary, regardless of the treatment group. LIMITATIONS, The 6-month follow-up was too short to demonstrate any long-term differences in the ovulation rates. Future research should therefore extend the follow-up beyond 6 months. Another limitation is that ULOD was used to treat only the right ovary. Future studies should investigate whether ULOD treatment of the larger ovary, whether left or right, would significantly increase the ovulation rate. This study represents an advance in the determination of the optimal laparoscopic treatment for women with PCOS, as it was shown that improved results can be achieved using less thermal energy in volume-adjusted ULOD.

Prolactin (PRL) is an anterior pituitary hormone which has its principle physiological action in initiation and maintenance of lactation. In human reproduction, pathological hyperprolactinemia most commonly presents as an ovulatory disorder and is often associated with secondary amenorrhea or oligomenorrhea. Galactorrhea, a typical symptom of hyperprolactinemia, occurs in less than half the cases. Out of the causes of hyperprolactinemia, pituitary tumors may be responsible for almost 50% of cases and need to be investigated especially in the absence of history of drug induced hyperprolactinemia. In women with hyperprolactinemic amenorrhea one important consequence of estrogen deficiency is osteoporosis, which deserves specific therapeutic consideration. Problem in diagnosing and treating hyperprolactinemia is the occurrence of the 'big big molecule of prolactin' that is biologically inactive (called macroprolactinemia), but detected by the same radioimmunoassay as the biologically active prolactin. This may explain many cases of very high prolactin levels sometimes found in normally ovulating women and do not require any treatment. Dopamine agonist is the mainstay of treatment. However, presence of a pituitary macroadenoma may require surgical or radiological management.
The risk of recurrent venous thromboembolism (VTE) in young women after a first oestrogen contraception associated VTE episode is unknown. This uncertainty has an impact on the decision whether to stop anticoagulant treatment. Our objective was to assess the risk of recurrent VTE in women after a first VTE episode on oestrogen contraception. This was a prospective cohort study in which we consecutively enrolled between 1992 and 2011 all women under 50years with a first objectively confirmed VTE. The incidence of recurrent VTE during follow-up after stopping anticoagulation was compared between women users and non-users of combined oral contraception (COC) at the time of index VTE. Of the 241 women aged 50 or younger seen for a first VTE and followed-up after stopping anticoagulation, there were 180 COC-users and 61 non-users. Median duration of follow-up off-anticoagulants was 66 months (interquartile 33-103). There were 14 recurrences in COC-users and 5 cases in non-users. No significant association was found between exposure to COC and the incidence of recurrent VTE after adjustment for age or after restricting the analysis incidence rate of recurrence 17.9/1,000/year (95% CI: 9.6-33.2) in women with COC as compared with 17.6/1,000/year (95% CI: 6.6-47) with an incidence ratio of 0.7 (95% CI: 0.2-2.4, p=0.59). The risk of recurrent VTE is low in young women after a first VTE. However, this risk is not significantly lower in women after a first VTE while exposed to combined oral contraception.
Oxidative stress can contribute to impairment in spermatogenesis leading to male-factor infertility. The effectiveness of various antioxidants (such as carnitine, vitamin C, vitamin E, selenium, carotenoids, glutathione, N-acetylcysteine, zinc, folic acid, and coenzyme Q10) is variable with respect to improving semen parameters and pregnancy rates. A recent Cochrane review determined that men taking antioxidants had a statistically significant increase in both live birth rates and pregnancy rates. For those undergoing assisted reproduction, the odds ratio that antioxidant use would improve pregnancy rates was 4.18, with a 4.85-fold improvement in live birth rate also noted. Further investigation with randomized, controlled clinical trials is needed to confirm the safety and efficacy of antioxidant supplementation in the medical management and treatment of male infertility.
To serve as a pilot feasibility study for a randomized study of excision versus ablation in the treatment of endometriosis by (1) estimating the magnitude of change in symptoms after excision only at multiple referral centers and (2) determining the proportion of women willing to participate in a randomized trial. We performed a multicenter prospective study of women undergoing excision for endometriosis (Canadian Task Force class II-3) at Duke University Center for Endometriosis Research & Treatment (currently the Saint Louis University Center for Endometriosis), Center for Endometriosis Care, Northshore University Health System, Memorial University (Canada), and Florida Hospital. The study comprised 100 female patients, aged 18 to 55 years, with endometriosis-suspected pelvic pain. The intervention was laparoscopic excision only of the abnormal peritoneum suspicious for endometriosis. The main outcome measures were quality of life, pelvic pain, dysmenorrhea, dyspareunia, and bowel and bladder symptoms. The mean follow-up period was 8.5 months. Excision of endometriosis showed a significant reduction in all pain scores except bowel symptoms, as well as significant improvement in quality of life. Of the patients, 84% were willing to participate in a randomized study. Quality of life is a needed primary outcome for any randomized study comparing excision versus ablation. A multicenter comparative trial is feasible, although quality assurance would have to be addressed. Patients were willing to be randomized even at surgical referral centers.

Urged by the unmet medical needs in endometriosis treatment, often with undesirable side effects, and encouraged by N-acetylcysteine (NAC) efficacy in an animal model of endometriosis and by the virtual absence of toxicity of this natural compound, we performed an observational cohort study on ovarian endometriosis. NAC treatment or no treatment was offered to 92 consecutive Italian women referred to our university hospital with ultrasound confirmed diagnosis of ovarian endometriosis and scheduled to undergo laparoscopy 3 months later. According to patients acceptance or refusal, NAC-treated and untreated groups finally comprised 73 and 72 endometriomas, respectively. After 3 months, within NAC-treated patients cyst mean diameter was slightly reduced (-1.5 mm) versus a significant increase (+6.6 mm) in untreated patients (P = 0.001). Particularly, during NAC treatment, more cysts reduced and fewer cysts increased their size. Our results are better than those reported after hormonal treatments. Twenty-four NAC-treated patients-versus 1 within controls-cancelled scheduled laparoscopy due to cysts decrease/disappearance and/or relevant pain reduction (21 cases) or pregnancy (1 case). Eight pregnancies occurred in NAC-treated patients and 6 in untreated patients. We can conclude that NAC actually represents a simple effective treatment for endometriosis, without side effects, and a suitable approach for women desiring a pregnancy.
Endometriosis-associated chronic pelvic pain (EACPP) presents with an intense inflammatory reaction. Melatonin has emerged as an important analgesic, antioxidant, and antiinflammatory agent. This trial investigates the effects of melatonin compared with a placebo on EACPP, brain-derived neurotrophic factor (BDNF) level, and sleep quality. Forty females, aged 18 to 45 years, were randomized into the placebo (n = 20) or melatonin (10 mg) (n = 20) treatment groups for a period of 8 weeks. There was a significant interaction (time vs group) regarding the main outcomes of the pain scores as indexed by the visual analogue scale on daily pain, dysmenorrhea, dysuria, and dyschezia (analysis of variance, P < 0.01 for all analyses). Post hoc analysis showed that compared with placebo, the treatment reduced daily pain scores by 39.80% (95% confidence interval [CI] 12.88-43.01%) and dysmenorrhea by 38.01% (95% CI 15.96-49.15%). Melatonin improved sleep quality, reduced the risk of using an analgesic by 80%, and reduced BNDF levels independently of its effect on pain. This study provides additional evidence regarding the analgesic effects of melatonin on EACPP and melatonin's ability to improve sleep quality. Additionally, the study revealed that melatonin modulates the secretion of BDNF and pain through distinct mechanisms.
Numerous epidemiologic studies have demonstrated that premenstrual disorders (PMDs) begin during the teenage years. At least 20 % of adolescents experience moderate-to-severe premenstrual symptoms associated with functional impairment. Premenstrual syndrome (PMS) consists of physical and/or psychological premenstrual symptoms that interfere with functioning. Symptoms are triggered by ovulation and resolve within the first few days of menses. The prevalence of premenstrual dysphoric disorder (PMDD), a severe form of PMS accompanied by affective symptoms, is likely equal to or higher than in adults. The diagnosis of a PMD requires a medical and psychological history and physical examination but it is the daily prospective charting of bothersome symptoms for two menstrual cycles that will clearly determine if the symptoms are related to a PMD or to another underlying medical or psychiatric diagnosis. The number and type of symptoms are less important than the timing. Randomized controlled trials of pharmacologic treatments in teens with moderate-to-severe PMS and PMDD have yet to be performed. However, clinical experience suggests that treatments that are effective for adults can be used in adolescents. PMS can be ameliorated by education about the nature of the disorder, improving calcium intake, performing exercise and reducing stress, but to treat severe PMS or PMDD pharmacologic therapy is usually required. Eliminating ovulation with certain hormonal contraceptive formulations or gonadotropin-releasing hormone agonists will be discussed. Serotonergic agonists are a first-line therapy for adults, and some serotonin reuptake inhibitors such as fluoxetine and escitalopram can be administered safely to teens.
We sought to identify risk factors for endometriosis and their consistency across study populations Natural History, Diagnosis, and Outcomes (ENDO) Study. In this prospective matched, exposure cohort design, 495 women aged 18-44 years undergoing pelvic surgery (exposed to surgery, operative cohort) were compared to an ageand residence-matched population cohort of 131 women (unexposed to surgery, population cohort). Endometriosis was diagnosed visually at laparoscopy/laparotomy or by pelvic magnetic resonance imaging in the operative and population cohorts, respectively. Logistic regression estimated the adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for each cohort. The incidence of visualized endometriosis was 40% in the operative cohort (11.8% stage 3-4 by revised criteria from the American Society for Reproductive Medicine), and 11% stage 3-4 in the population cohort by magnetic resonance imaging. An infertility history increased the odds of an endometriosis diagnosis in both the operative (AOR, 2.43; 95% CI, 1.57-3.76) and population (AOR, 7.91; 95% CI, 1.69-37.2) cohorts. In the operative cohort only, dysmenorrhea (AOR, 2.46; 95% CI, 1.28-4.72) and pelvic pain (AOR, 3.67; 95% CI, 2.44-5.50) increased the odds of diagnosis, while gravidity (AOR, 0.49; 95% CI, 0.32-0.75), parity (AOR, 0.42; 95% CI, 0.28-0.64), and body mass index (AOR, 0.95; 95% CI, 0.93-0.98) decreased the odds of diagnosis. In all sensitivity analyses for different diagnostic subgroups, infertility history remained a strong risk factor. An infertility history was a consistent risk factor for endometriosis in both the operative and population cohorts of the ENDO Study. Additionally, identified risk factors for endometriosis vary based upon cohort selection and diagnostic accuracy. Finally, endometriosis in the population may be more common than recognized.

Management of congenital malformations comprises a large part of pediatric surgical care. Despite increasing utilization of assisted reproductive technology (ART) and fertility-related services (FRS), associations with birth defects are poorly understood. Infants born after ART or FRS were identified from the California Linked Birth Cohort Dataset from 2006 to 2007 and compared to propensity matched infants conceived naturally. Factors associated with major congenital malformations were evaluated using Firth logistic regression. With a cohort of 4,795 infants born after ART and 46,025 naturally conceived matched controls, major congenital malformations were identified in 3,463 infants. Malformations were increased for ART infants (9.0% vs. 6.6%, p<0.001). After adjusting for infant and maternal factors, ART infants exhibited increased odds of major malformations overall (OR 1.25, 95% CI 1.12-1.39), specifically defects of the eye (OR 1.81, 95% CI 1.04-3.16), head and neck (OR 1.37, 95% CI 1.00-1.86), heart (OR 1.41, 95% CI 1.22-1.64), and genitourinary system (OR 1.40, 95% CI 1.09-1.82). The likelihood of birth defects was increased for multiples (OR 1.35, 95% CI 1.18-1.54) and not singletons. Odds of congenital malformation after FRS alone (n=1,749) were non-significant. ART contributes a significant risk of congenital malformation and may be more pronounced for multiples. Accurate counseling for parents considering ART and multidisciplinary coordination of care prior to delivery are warranted.

Calcium and vitamin D are recommended for bone health, but there are concerns about adverse risks. Some clinical studies suggest that calcium intake may be cardioprotective, whereas others report increased risk associated with calcium supplements. Both low and high serum levels of 25-hydroxyvitamin D have been associated with increased mortality. The purpose of this study was to determine the association between total calcium and vitamin D intake and mortality and heterogeneity by source of intake. The Canadian Multicentre Osteoporosis Study cohort is a population-based longitudinal cohort with a 10-year follow-up (1995-2007). This study included randomly selected community-dwelling men and women. A total of 9033 participants with nonmissing calcium and vitamin D intake data and follow-up were studied. Total calcium intake (dairy, nondairy food, and supplements) and total vitamin D intake (milk, yogurt, and supplements) were recorded. The outcome variable was all-cause mortality. There were 1160 deaths during the 10-year period. For women only, we found a possible benefit of higher total calcium intake, with a hazard ratio of 0.95 (95% confidence interval, 0.89-1.01) per 500-mg increase in daily calcium intake and no evidence of heterogeneity by source; use of calcium supplements was also associated with reduced mortality, with hazard ratio of 0.78 (95% confidence interval, 0.66-0.92) for users vs nonusers with statistically significant reductions remaining among those with doses up to 1000 mg/d. These associations were not modified by levels of concurrent vitamin D intake. No definitive associations were found among men. Calcium supplements, up to 1000 mg/d, and increased dietary intake of calcium may be associated with reduced risk of mortality in women. We found no evidence of mortality benefit or harm associated with vitamin D intake.

To review the literature on the effects of diet on endometriosis and dysmenorrhoea. A systematic search for trials investigating a relationship between diet and endometriosis/dysmenorrhoea was undertaken, and 23 studies were included in this review. Data on the relationship between diet and endometriosis were limited to 12 trials, three of which were animal studies, resulting in a total of 74,708 women. One large study (n=70,709) found a relatively strong association between endometriosis and trans-fatty acid consumption, and a lower risk of endometriosis with increased consumption of long-chain omega-3 fatty acids. The latter finding was also supported by smaller studies. No further dietary recommendations for reducing the risk of endometriosis were possible, and results for intake of vegetable, fibre and fruit were equivocal. The relationship between diet and dysmenorrhoea was investigated in 11 trials with different designs, including a total of 1433 women. Intake of fish oil seemed to reduce dysmenorrhoea. The literature on endometriosis and dysmenorrhoea in relation to diet is sparse, yielding equivocal results on specific elements. Overall, however, the literature suggests that specific types of dietary fats are associated with endometriosis and/or dysmenorrhoea, thereby indicating that there may be modifiable risk factors. Further research is recommended on both subjects.
Initial evaluation of the patient with acute abnormal uterine bleeding should include a prompt assessment for signs of hypovolemia and potential hemodynamic instability. After initial assessment and stabilization, the etiologies of acute abnormal uterine bleeding should be classified using the PALM-COEIN system. Medical management should be the initial treatment for most patients, if clinically appropriate. Options include intravenous conjugated equine estrogen, multi-dose regimens of combined oral contraceptives or oral progestins, and tranexamic acid. Decisions should be based on the patient's medical history and contraindications to therapies. Surgical management should be considered for patients who are not clinically stable, are not suitable for medical management, or have failed to respond appropriately to medical management. The choice of surgical management should be based on the patient's underlying medical conditions, underlying pathology, and desire for future fertility. Once the acute bleeding episode has been controlled, transitioning the patient to long-term maintenance therapy is recommended.
Contraception/ComparisonReproductive Endocrinology
Open Access
The glucocorticoid receptor (GR) regulates several physiological functions, including immune function and apoptosis. The HIV-1 virus accessory protein, viral protein R (Vpr), can modulate the transcriptional response of the GR. Glucocorticoids (GCs) and Vpr have been reported to induce apoptosis in various cells, including T-cells. We have previously shown that the injectable contraceptive, medroxyprogesterone acetate (MPA) is a partial to full agonist for the GR, unlike norethisterone acetate (NET-A). We investigated the functional cross talk between the GR and Vpr in inducing apoptosis in CD4(+) T-cells, in the absence and presence of GCs and these progestins, as well as progesterone. By using flow cytometry, we show that, in contrast to NET-A and progesterone, the synthetic GR ligand dexamethasone (Dex), cortisol and MPA induce apoptosis in primary CD4(+) T-cells. Furthermore, the C-terminal part of the Vpr peptide, or HIV-1 pseudovirus, together with Dex or MPA further increased the apoptotic phenotype, unlike NET-A and progesterone. By a combination of Western blotting, PCR and the use of receptorselective agonists, we provide evidence that the GR and the estrogen receptor are the only steroid receptors expressed in peripheral blood mononuclear cells. These results, together with the findings that RU486, a GR antagonist, prevents Dex-, MPAand Vpr-mediated apoptosis, provide evidence for the first time that GR agonists or partial agonists increase apoptosis in primary CD4(+) T-cells via the GR. We show that apoptotic induction involves differential expression of key apoptotic genes by both Vpr and GCs/MPA. This work suggests that contraceptive doses of MPA but not NET-A or physiological doses of progesterone could potentially accelerate depletion of CD4(+) T-cells in a GR-dependent fashion in HIV-1 positive women, thereby contributing to immunodeficiency. The results imply that choice of progestin used in contraception may be critical to susceptibility and progression of diseases such as HIV-1.

Children conceived via assisted reproductive technologies (ART) are nowadays a substantial proportion of the population. It is important to follow up these children and evaluate whether they have elevated health risks compared to naturally conceived (NC) children. In recent years there has been a lot of work in this field. This review will summarize what is known about the health of ART-conceived children, encompassing neonatal outcomes, birth defects, growth and gonadal developments, physical health, neurological and neurodevelopmental outcomes, psychosocial developments, risk for cancer, and epigenetic abnormalities. Most of the children conceived after ART are normal. However, there is increasing evidence that ART-conceived children are at higher risk of poor perinatal outcome, birth defects, and epigenetic disorders, and the mechanism(s) leading to these changes have not been elucidated. Continuous follow-up of children after ART is of great importance as they progress through adolescence into adulthood, and new ART techniques are constantly being introduced.
To determine patterns of usage of clomiphene citrate (CC) by primary care providers (obstetrician-gynecologists, family physicians, and other providers) within University of Utah Community Clinics. We performed a retrospective chart review (n = 79) and followup telephone survey of patients (n = 43) who were prescribed CC in the University of Utah Community Clinics in 2006. Most women who were prescribed CC had appropriate indications for therapy (65% with a diagnosis related to irregular menses and 33% with a diagnosis of female infertility), but there was variable and inconsistent monitoring of ovulation (much of which was apparently initiated by the patients). In the interview, 24 of the women (56%) said they would be fine having twins, and 14 (33%) said they would prefer to have twins if possible. In this primary care setting, clomiphene was prescribed for appropriate indications, but the monitoring of treatment could be improved. The preference of some patients for twin gestations represents a challenge for optimum clinical care and public health.
InfertilityTreatment Utilization PatternsOvulation MonitoringTiming and Appropriateness
The purpose of this study was to compare the utilization of medical help for fertility among women who reported up to a year versus more than a year of trying to become pregnant and to describe the characteristics of those women seeking early treatment. Data from the 2004-2008 Pregnancy Risk Assessment Monitoring System (PRAMS) survey were used to assess attempt duration and use of fertility treatments in a sample of 9,517 women who had a recent live birth in Utah. PRAMS respondents who were trying to become pregnant at the time of conception were asked questions about fertility treatments (sampling n = 5,238; representative n = 153,036). Univariate and bivariate analyses were used to describe and compare characteristics of women who sought treatment after attempting pregnancy for a year or less and women who waited at least a year to seek treatment. Among women who were trying to become pregnant, 9.5 % reported using some medical assistance to conceive. Among the women trying to become pregnant, 89.3 % had been trying for ≤12 months and 10.7 % reported having tried >12 months. 5.2 % of those trying to become pregnant for up to a year reported use of fertility treatment, compared with 45.8 % of those trying for a year or more. Women who had previous live births were significantly more likely to use early treatment than nulliparous women (aOR = 2.4, 95 % CI = 1.5, 3.9). The use of fertility drugs and other treatments were more common than ART among recipients of early treatment (aOR = 3.7, 95 % CI = 1.7, 7.9). Some women may be receiving fertility treatment before it is clinically indicated. Instead of invasive treatment, these women may benefit from preconception counseling on folic acid, healthy prepregnancy weight and use of ovulation monitoring to time intercourse.
Concerns about weight gain may influence contraceptive use. We compared the change in body weight over the first 12 months of use between women using the etonogestrel (ENG) implant, the levonorgestrel intrauterine system (LNG-IUS) or depot medroxyprogesterone acetate (DMPA) with women using the copper intrauterine device (IUD). This was a substudy of the Contraceptive CHOICE Project, a prospective cohort study of 9256 women provided no-cost contraception. Women who had been using the ENG implant, LNG-IUS, DMPA or copper IUD continuously for at least 11 months were eligible for participation. We obtained body weight at enrollment and at 12 months and compared the weight change for each progestin-only method to the copper IUD. We enrolled a total of 427 130 ENG implant users, 130 LNG-IUS users, 67 DMPA users and 100 copper IUD users. The mean weight change (in kilograms) over 12 months was 2.1 for ENG implant users [standard deviation (SD)=6.7]; 1.0 for LNG-IUS users (SD=5.3); 2.2 for DMPA users (SD=4.9) and 0.2 for copper IUD users (SD=5.1). The range of weight change was broad across all contraceptive methods. In the unadjusted linear regression model, ENG implant and DMPA use were associated with weight gain compared to the copper IUD. However, in the adjusted model, no difference in weight gain with the ENG implant, LNG-IUS or DMPA was observed. Only Black race was associated with significant weight gain (1.3 kg, 95% confidence interval=0.2-2.4) when compared to other racial groups. Weight change was variable among women using progestin-only contraceptives. Black race was a significant predictor of weight gain among contraceptive users.
Progesterone with its anti-seizure effect plays a role in the pathophysiology of catamenial epilepsy which affects 31-60% of epileptic women. In this study, an attempt to treat women suffering from catamenial epilepsy with progesterone, as an adjuvant drug, was made. The treatment was given to 36 women aged 20-40 years (mean 30.75±6.05) with seizures in the entire second half of the menstrual cycle, who were found to have low serum levels of progesterone on days 22, 27, 28 of the cycle in comparison with a control group of healthy women. The patients were administered progesterone in a daily dose of 50 mg on days 16-25 of each cycle. The serum levels of antiepileptic drugs were assayed. The period of progesterone therapy ranged from 3 to 45 months (17.7 on average). Three patients were free of secondary generalized seizures, and one--of simple partial seizures. A decline in the frequency of primary and secondary generalized seizures by 20-96% (55.9% on average) was accomplished in 18 patients (primary generalized by 20-96%--54.7% on average, and secondarily generalized by 38-85%--59% on average). A decline in the frequency of complex partial seizures by 38-87% (63.1% on average) was achieved in 15 women. In 1 patient, the frequency of myoclonic seizures decreased by 46%. There was no improvement in 5 women (3 patients with generalized, 1 with complex partial and 1 with simple partial seizures). An exacerbation of seizure frequency occurred in 5 patients. Adverse effects were not found in any of the subjects. The average concentrations of antiepileptic drugs during hormonal therapy were in the therapeutic range. Progesterone combined with antiepileptic therapy was well tolerated and resulted in a significant reduction of seizure frequency in majority of patients with catamenial epilepsy.

In women with obsessive-compulsive disorder (OCD), symptom severity appears to fluctuate over the course of the menstrual cycle. The objective of this paper was to compare female OCD patients with and without premenstrual worsening of obsessive-compulsive symptoms (OCS), in terms of the clinical characteristics of OCD. This was a cross-sectional study involving 455 women with OCD, of whom 226 (49.7%) had experienced premenstrual OCS worsening and 229 (50.3%) had not (PMOCS-worse and PMOCS-same groups, respectively). Data were collected with the original and dimensional versions of the Yale-Brown obsessive-compulsive scale, as well as with the Beck Depression Inventory (BDI) and Beck anxiety inventory (BAI). We found significant differences between the PMOCS-same and PMOCS-worse groups, the latter showing a higher frequency of suicidal ideation (P<.001), suicide attempts (P=.027), current use of selective serotonin reuptake inhibitors (P=.022), lifetime use of mood stabilisers (P=.015), and sexual/religious obsessions (P<.001; OR=1.90), as well as higher scores on the BDI (P<.001) and BAI (P<.001). Underscoring the fact that OCD is a heterogeneous disorder, there appears to be a subgroup of female OCD patients in whom the premenstrual period is associated with a higher frequency of sexual/religious obsessions, depression, anxiety, and suicidality. This might be attributable to hormonal fluctuations. Further studies are warranted in order to investigate this hypothesis by evaluating such patients at different phases of the menstrual cycle, as well as measuring hormonal levels.
Although perimenstrual asthma (PMA) has been associated with severe and difficult-to-control asthma, it remains poorly characterized and understood. The objectives of this study were to identify clinical, demographic, and inflammatory factors associated with PMA and to assess the association of PMA with asthma severity and control. Women with asthma recruited to the National Heart, Lung, and Blood Institute Severe Asthma Research Program who reported PMA symptoms on a screening questionnaire were analyzed in relation to basic demographics, clinical questionnaire data, immunoinflammatory markers, and physiologic parameters. Univariate comparisons between PMA and non-PMA groups were performed. A severity-adjusted model predicting PMA was created. Additional models addressed the role of PMA in asthma control. Self-identified PMA was reported in 17% of the subjects (n = 92) and associated with higher BMI, lower FVC % predicted, and higher gastroesophageal reflux disease rates. Fifty-two percent of the PMA group met criteria for severe asthma compared with 30% of the non-PMA group. In multivariable analyses controlling for severity, aspirin sensitivity and lower FVC % predicted were associated with the presence of PMA. Furthermore, after controlling for severity and confounders, PMA remained associated with more asthma symptoms and urgent health-care utilization. PMA is common in women with severe asthma and associated with poorly controlled disease. Aspirin sensitivity and lower FVC % predicted are associated with PMA after adjusting for multiple factors, suggesting that alterations in prostaglandins may contribute to this phenotype.
Patients previously treated with desiccated thyroid extract (DTE), when being switched to levothyroxine (L-T₄), occasionally did not feel as well despite adequate dosing based on serum TSH levels. Our objective was to investigate the effectiveness of DTE compared with L-T₄ in hypothyroid patients. We conducted a randomized, double-blind, crossover study at a tertiary care center. Patients (n = 70, age 18-65 years) diagnosed with primary hypothyroidism on a stable dose of L-T₄ for 6 months were included in the study. Patients were randomized to either DTE or L-T₄ for 16 weeks and then crossed over for the same duration. Biochemical and neurocognitive tests at baseline and at the end of each treatment period were evaluated. There were no differences in symptoms and neurocognitive measurements between the 2 therapies. Patients lost 3 lb on DTE treatment (172.9 ± 36.4 lb vs 175.7 ± 37.7 lb, P < .001). At the end of the study, 34 patients (48.6%) preferred DTE, 13 (18.6%) preferred L-T₄, and 23 (32.9%) had no preference. In the subgroup analyses, those patients who preferred DTE lost 4 lb during the DTE treatment, and their subjective symptoms were significantly better while taking DTE as measured by the general health questionnaire-12 and thyroid symptom questionnaire (P < .001 for both). Five variables were predictors of preference for DTE. DTE therapy did not result in a significant improvement in quality of life; however, DTE caused modest weight loss and nearly half (48.6%) of the study patients expressed preference for DTE over L-T₄. DTE therapy may be relevant for some hypothyroid patients.
Contraception/ComparisonHIV RiskSide EffectsSecondary Data Analysis
To evaluate the effect of oral and injectable hormonal contraception on the risk of HIV acquisition among women in South Africa and Zimbabwe.
Secondary data analysis of 4913 sexually active women aged 18-49 years followed for up to 24 months in the Methods for Improving Reproductive Health in Africa (MIRA) phase III effectiveness trial of the diaphragm and lubricant gel for HIV prevention. Participants were interviewed quarterly about contraception and sexual behavior and were tested for pregnancy, HIV, and other sexually transmitted infections. We used a Cox proportional hazards marginal structural model, weighted by the inverse probability of hormonal contraception use, to compare the risk of HIV acquisition among nonpregnant women reporting use of combined oral contraceptive pills (COC), progestin-only pills (POP), and/or injectable hormonal contraception to women not using these methods. During the study, 283 participants seroconverted. Use of oral contraceptives (POP or COC) was not associated with HIV risk [adjusted hazard ratio (HRa) = 0.86, 95% confidence interval (CI) 0.32, 1.78]. Injectable hormonal contraception was associated with a small nonsignificant risk of HIV infection (HR(a) = 1.34, 95% CI 0.75, 2.37). The effect of injectable hormonal contraception was similar in the unweighted site-adjusted only (HR(a) = 1.32, 95% CI 1.00, 1.74) and baseline factor adjusted models (HR(a) = 1.27, 95% CI 0.94, 1.72). In this study, oral contraceptives were not associated with HIV acquisition. There is substantial uncertainty in the effect of injectable hormonal contraception on HIV risk. These findings underscore the importance of dual protection with condoms and the need for diverse contraceptive options for women at risk of HIV infection.
To assess the influence of an isotonic lubricant used during sperm sample collection on [1] ease of collection and [2] resultant sperm quality. Paired randomized cross-over design. Tertiary hospital. DONOR(S): Healthy men over 18 years old with normal semen analysis as per World Health Organization 2010 guidelines. INTERVENTION(S): Collection of semen sample from 22 subjects by masturbation with or without the use of Pre-Seed personal lubricant. MAIN OUTCOME MEASURE(S): Qualitative survey results and quantitative sperm function outcomes were measured to determine resultant sperm quality and collection experience with and without Pre-Seed lubricant. RESULT(S): The qualitative questionnaire results showed that 73% of donors prefer the semen collection process with the isotonic lubricant and 55% recommended the use of lubricant in their everyday collection. The motility, viability, membrane integrity, levels of reactive oxygen species, total antioxidant capacity, and percentage of DNA damage in collected semen samples were not affected by the use of the lubricant. CONCLUSION(S): More donors prefer, and find it easier, to collect semen samples with the use of the lubricant. The isotonic lubricant Pre-Seed did not compromise sperm quality as evaluated in an array of sperm assays, suggesting its safe use in fertility patients as required during sperm collection.
NaProTECHNOLOGYInfertility TreatmentAdhesion PreventionReproductive Medicine
In the last 50 years, a surge of reproductive technology has revolutionized the practice of obstetrics and gynecology. First, effective hormonal contraceptives were made available to the public in the 1960s and, since their debut, have been used to treat almost every gynecologic abnormality [1]. Second, in the past 30 years, infertility has largely been managed using assisted reproductive technologies (ART), primarily intrauterine insemination (IUI) with recourse to in vitro fertilization (IVF) when insemination fails [2]. As a result, the modus operandi in mainstream gynecology has been to suppress, or to bypass, the woman’s fertility cycle.
Physicians and patients who (1) conscientiously object to the therapeutic use of hormonal contraceptives on the grounds that it subjects patients to ineffective treatment of symptoms rather than treating their underlying disease and (2) morally oppose the ART approach to infertility on the grounds that it jettisons a loving act of marital intercourse, the one context worthy of the conception of a new human being, are now able to pursue an alternative approach that accords with their consciences. NaProTECHNOLOGY (an acronym for natural procreative technology) is a woman’s health science that encompasses a unique medical and surgical application of gynecology. The foundation of NPT is the Creighton Model FertilityCare System (CrMS), see Figure 1, the only prospective and standardized means of monitoring the various patterns of a woman’s menstrual and fertility cycle for the natural regulation of fertility.
For example, because it views infertility as a symptom rather than a disease, NPT seeks to diagnose and treat the underlying causes of infertility so that the couple can more successfully conceive within their own acts of intercourse, especially during peak-day-focused intercourse. NPT infertility protocols depend on patient-specific charting data. Some observations during the fertility cycle—dry, limited, or continuous mucus; short or variable post-peak phase; premenstrual spotting or tail-end brown bleeding—are external signs of possible underlying disease processes.
A medical interpretation of these abnormal CrMS observations leads to a targeted biochemical and hormonal evaluation, which in turn identifies decreased production of estrogenic cervical mucus, intermenstrual bleeding or spotting, short or variable luteal phases, and suboptimal levels of the ovarian hormones (estrogen or progesterone). Common treatments for these pathologies include induction or stimulation of ovulation, medications to enhance cervical mucus, and hormonal support in the luteal phase. When these NPT medical approaches to infertility were used in a study of 1,239 infertile couples, they resulted in a live birth rate similar to that of cohort ART treatments [3].
In many cases, medical applications of NPT are sufficient to treat infertility successfully; in other cases, surgical intervention is also required. Surgical NPT is a specialized form of gynecologic surgery the primary aim of which is to reconstruct the uterus, fallopian tubes, and ovaries. The ovarian wedge resection (surgical removal of a portion of an enlarged ovary to restore its normal size), for example, is effective in healing polycystic ovaries (contributing to the long-term treatment of some of the endocrine and menstrual cycle abnormalities associated with polycystic ovaries). It also brings the patient a 70 percent chance of pregnancy i.e., it is twice as effective as clomiphene [4].
A significant benefit of surgical NaProTECHNOLOGY is “near adhesion-free” surgery. One of the biggest pitfalls of surgery, of course, is the formation of postoperative adhesions, which can decrease tubal motility (adversely affecting fertility) and cause small bowel obstructions (that frequently require emergency reoperation) [5]. To prevent these complications, NPT surgical techniques pay meticulous attention to detail, take a systematic approach, and use Gore-Tex adhesion barriers [6]. Published Gore-Tex protocols reveal a statistically significant decrease in subsequent adhesion scores on second-look laparoscopy [7]. For some reason, the use of Gore-Tex has been overlooked in even the most recent adhesion prevention reviews [8]. One even laments that adhesion prevention is a “surprisingly neglected aspect of the treatment of endometriosis,” but the reviewers make no mention of the use of Gore-Tex as an adhesion barrier.
Other techniques of surgical NPT include laser vaporization and pelvic excision and repair surgery (PEARS) of peritoneal or ovarian endometriosis. PEARS is a form of plastic reconstructive surgery of the pelvis with the primary intent of removing diseased tissue within the pelvic organs and repairing organs in a way that does not form pelvic adhesions. PEARS can entail robot-assisted laparoscopy or laparotomy, minimizing postoperative adhesions and optimizing the patient’s chances for pregnancy.
The effectiveness of treating infertility with medical and surgical NPT is comparable to that of ART interventions. The cumulative live birth rate in patients receiving IVF is between 45-55% [10]. In a study population of 1,045 patients treated with NPT infertility protocols, more than 60 percent became pregnant within 24 months and nearly 70 percent within 36 months [11]. The overall �per-woman� NPT pregnancy rate is higher than that of ART due, in part, to the high rate of dropout or discontinuation in patients who undergo IVF treatment [12]. In addition, a meta-analysis comparing conventional surgery and IVF for treatment of endometriosis-related infertility found that the per-woman pregnancy rates with surgery were 55.3 percent while those with IVF were 9.9 percent [13]. However, while it is true patients treated with NPT have significantly lower overall fecundability (a 3.13 percent chance of conceiving within a given period) than those treated with IVF (13.3 percent), it is also true that the number of women who ultimately achieve a pregnancy with NPT is higher than the number who get pregnant using ART [14]. Thus, although achieving a live birth with NPT may take longer, it has a greater chance of occurring than with IVF.
For those interested in training in NPT, the Pope Paul VI Institute and Creighton University School of Medicine offer educational programs for those in primary care or ob/gyn (including fourth-year medical students) to train in the medical applications of NaProTECHNOLOGY [15]. They also offer a 1-year fellowship in the surgical applications of NPT for ob/gyns who have completed their residencies [16].
Nausea and vomiting during pregnancy are the most common conditions affecting pregnancy, occurring in about 80% of all pregnancies and always disappearing on the 16th to 18th weeks of gestation. This may be mild and it does not affect the general condition of the patient (the condition is called emesis gravidarum), or it may be severe enough to affect the patient physically and psychologically, causing intractable vomiting, electrolyte imbalance, weight loss >5%, impairment of liver and kidney functions and dehydration. Helicobacter pylori is one of the most common bacterium affecting humans. It is a gram-negative helix-shaped microaerophilic bacterium transmitted by the oro-oral or feco-oral route. It is more prevalent in developing countries and affects young children. Acute infection manifests as acute gastritis and stomach pain, whereas chronic infection causes chronic gastritis and peptic ulcer, 2% of which may develop into stomach cancer. The authors tried to investigate the association between H pylori infection and hyperemesis gravidarum. Fifty patients with hyperemesis gravidarum and 50 patients with normal pregnancy were included in the study. H pylori infection was determined using a 1-step H pylori test device (serum/plasma), which is a qualitative membrane-based immunoassay. Regarding maternal age, gestational age and socioeconomic status, there is no statistical difference between both groups. There is a marked statistical difference between both groups in terms of Helicobacter pylori seropositivity and frequency of vomiting. There is a powerful correlation between H pylori and hyperemesis gravidarum.
To assess in utero exposures and the odds of an endometriosis diagnosis.
Matched cohort design.
Fourteen participating clinical centers in geographically defined areas in Utah and California. PATIENT(S): Operative cohort comprised 473 women undergoing laparoscopy/laparotomy, and an ageand residence-matched population cohort comprising 127 women undergoing pelvic magnetic resonance imaging (MRI), 2007-2009. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Women completed standardized interviews mothers' lifestyle during the index pregnancy, and the index woman's gestation and birth size. Endometriosis was defined as visually confirmed disease in the operative cohort, and MRI visualized disease in the population cohort. The odds of an endometriosis diagnosis and corresponding 95% confidence intervals (CI) were estimated for each exposure by cohort using logistic regression and adjusting for current smoking, age at menarche, body mass index, and study site. RESULT(S): Endometriosis was diagnosed in 41% and 11% of women in the operative and population cohorts, respectively. In the primary analysis, adjust odds ratios (AORs) were elevated for maternal vitamin usage (1.27; 95% CI, 0.85-1.91), maternal cigarette smoking (1.16; 95% CI = 0.61-2.24), and low birth weight (1.1; 95% CI, 0.92-1.32). Reduced odds were observed for maternal usage of caffeine (0.99; 95% CI, 0.64-1.54), alcohol (0.82; 95% CI, 0.35-1.94), paternal cigarette smoking (0.72; 95% CI, 0.43-1.19), and preterm delivery (0.98; 95% CI, 0.47-2.03). Sensitivity analyses mostly upheld the primary results except for a decreased AOR for preterm birth (0.41; 95% CI, 0.18-0.94) when restricting to visualized and histologically confirmed endometriosis in the operative cohort. CONCLUSION(S): In utero exposures were not statistically significantly associated with the odds of an endometriosis diagnosis in either cohort.
To review the literature and present original data to answer the question of whether in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is associated with an increase in imprinted diseases in offspring. If the answer is positive, to investigate whether there is a causal relationship between IVF or ICSI and the imprinted diseases. Review study. RESULT(S): Eight epidemiologic studies were suitable to calculate the weighted relative risk for the birth of a child with Beckwith-Wiedemann syndrome following IVF or ICSI compared with the risk in the normal population. This relative risk was 5.2 (95% CI 1.6-7.4). In one study the relative risk was corrected for parents' fertility problems and no significant association was found. Data on the Silver-Russell syndrome are too sparse to draw conclusions, but a positive association with IVF or ICSI treatment is probable. No significant associations were found between the incidences of the Angelman and Prader-Willi syndromes and IVF or ICSI treatments. Children with Prader-Willi syndrome or Angelman syndrome are more likely to be born to parents with fertility problems. All retinoblastomas in children born after IVF or ICSI could be explained by de novo mutations in the RB1 gene and were not associated with imprinted genes. Imprinted diseases result from methylation errors already present in sperms or oocytes. There is no proof of a causal relationship between imprinted diseases and IVF or ICSI treatments. CONCLUSION(S): Imprinting disorders are more prevalent after human IVF or ICSI. Future studies should correct for fertility problems in the affected and comparison groups. It is highly improbable that assisted reproduction technologies cause imprinted diseases in humans.
Worldwide, more than 5 million children have been born after assisted reproductive technology (ART), and in many developed countries ART infants represent more than 1% of the birth cohorts. It is well known that ART children are at increased risk of congenital malformations even after adjustment for known confounders such as maternal age. The proportion of ART children is not negligible, and knowledge about the causes of the higher risk of congenital malformations is crucial to develop prevention strategies to reduce the future risk in ART children. The aim of this review is to summarize the literature on the association between ART and congenital anomalies with respect to subfertility, fertility treatment other than ART, and different ART methods including intracytoplasmic sperm injection, blastocyst culture, and cryotechniques. Trends over time in ART and congenital anomalies will also be discussed.

Studies suggest that within-person changes in estrogen and progesterone predict changes in binge eating across the menstrual cycle. However, samples have been extremely small (maximum N = 9), and analyses have not examined the interactive effects of hormones that are critical for changes in food intake in animals. The aims of the current study were to examine ovarian hormone interactions in the prediction of within-subject changes in emotional eating in the largest sample of women to date (N = 196). Participants provided daily ratings of emotional eating and saliva samples for hormone measurement for 45 consecutive days. Results confirmed that changes in ovarian hormones predict changes in emotional eating across the menstrual cycle, with a significant estradiol × progesterone interaction. Emotional eating scores were highest during the midluteal phase, when progesterone peaks and estradiol demonstrates a secondary peak. Findings extend previous work by highlighting significant interactions between estrogen and progesterone that explain midluteal increases in emotional eating. Future work should explore mechanisms (e.g., gene-hormone interactions) that contribute to both within- and between-subjects differences in emotional eating.
Interrogating the association between assisted reproductive technologies (ART) and perinatal outcome is complicated but very important. This is an introduction to a series of articles that review this potential association with an eye toward etiology of risk, and what aspects of in vitro fertilization (IVF) can be modified to reduce this risk. When an association is not due to chance (i.e., statistically significant), one must also consider how the association may be affected due to bias or confounding. Despite lack of the perfect study, perinatal consequences of ART are apparent, even though the vast majority of children conceived with ART are healthy. Pregnancy after IVF is altered as evidenced by risk of preterm delivery, low birth weight among infants, and an alerted prevalence of preeclampsia. The long-term clinical implications of ART, such as childhood development and metabolism, have not been established and ongoing study is proceeding. The risk attributed to multiple births is iatrogenic and needs to be minimized. Optimizing the environment at the time a woman conceives will likely have an effect on gestation as well as the health of children. Reproduction effects health and health effects reproduction.
Von Willebrand disease (VWD) is a heterogeneous bleeding disorder caused by decrease or dysfunction of von Willebrand factor (VWF). A wide range of mutations in the VWF gene have been characterized; however, their cellular consequences are still poorly understood. Here we have used a recently developed approach to study the molecular and cellular basis of VWD. We isolated blood outgrowth endothelial cells (BOECs) from peripheral blood of 4 type 1 VWD and 4 type 2 VWD patients and 9 healthy controls. We confirmed the endothelial lineage of BOECs, then measured VWF messenger RNA (mRNA) and protein levels (before and after stimulation) and VWF multimers. Decreased mRNA levels were predictive of plasma VWF levels in type 1 VWD, confirming a defect in VWF synthesis. However, BOECs from this group of patients also showed defects in processing, storage, and/or secretion of VWF. Levels of VWF mRNA and protein were normal in BOECs from 3 type 2 VWD patients, supporting the dysfunctional VWF model. However, 1 type 2M patient showed decreased VWF synthesis and storage, indicating a complex cellular defect. These results demonstrate for the first time that isolation of endothelial cells from VWD patients provides novel insight into cellular mechanisms of the disease.
To estimate patient preferences insofar as the cosmetic appeal of abdominal incisions used for hysterectomy. We hypothesized that the laparoendoscopic single-site surgery (LESS) incision would be preferred cosmetically to traditional multiport laparoscopic incisions and open abdominal incisions via Pfannenstiel, vertical midline, or horizontal mini-laparotomy.
Prospective comparative study (Canadian Task Force classification II-2).
Two gynecology clinics at Duke University Medical Center in Durham, North Carolina. Seventy-three women including 50 consecutive women from a private specialty clinic and 23 consecutive women from a resident indigent care clinic. A brief questionnaire was distributed that assessed preferences via ranking and by using a visual analog scale. Patients were also asked to rate the importance of 4 factors size, location, and number of incisions, and perceived recovery time. Descriptive statistics, t tests, Wilcoxon rank-sum tests, and χ(2) tests were used to compare continuous or categorical values. MAIN Overall, the LESS incision was the most preferred incision according to most common choice and visual analog scale scores. In the private clinic, the LESS incision was preferred most often, with 53% of women (39/73) ranking it as their first choice. In the resident clinic, the horizontal mini-laparotomy incision was preferred most often, with 27% of women (20/73) ranking it their first choice. Neither the demographic factors nor any of the factors in decision making explained the difference between the clinics. The LESS incision was most preferred in this study. However, the horizontal mini-laparotomy incision and the traditional laparoscopic with low lateral incisions were also highly preferred. Patient perception of the "visibility" of abdominal incisions may be the distinguishing issue to explain the difference in the preferences between the clinics and the differences between the present study and previously published studies of cosmetic preferences.
Fertility AwarenessPostpartum ProtocolsReturn of FertilityPregnancy Avoidance Rates
The postpartum period is a challenging time for family planning, especially for women who breastfeed. Breastfeeding delays the return of menses (lactational amenorrhea), but ovulation often occurs before first menses. For this reason, a protocol was developed to assist women in identifying their return of fertility postpartum to avoid pregnancy. In this prospective, 12-month, longitudinal cohort study, 198 postpartum women aged 20 to 45 years (mean age, 30.2 years) were taught a protocol for avoiding pregnancy with either online or in-person instruction. A hand-held fertility monitor was used to identify the fertile period by testing for urinary changes in estrogen and luteinizing hormone, and the results were tracked on a web site. During lactational amenorrhea, urine testing was done in 20-day intervals. When menses returned, the monitor was reset at the onset of each new menstrual cycle. Participants were instructed to avoid intercourse during the identified fertile period. Kaplan-Meier survival analysis was used to calculate unintentional pregnancy rates through the first 12 months postpartum. There were 8 unintended pregnancies per 100 women at 12 months postpartum. With correct use, there were 2 unintended pregnancies per 100 women at 12 months. The online postpartum protocol may effectively assist a select group of women in avoiding pregnancy during the transition to regular menstrual cycles.
AbstractObjectiveTo determine whether low dosages (4.5 mg/day) of naltrexone reduce fibromyalgia severity as compared with the nonspecific effects of placebo. In this replication and extension study of a previous clinical trial, we tested the impact of low‐dose naltrexone on daily self‐reported pain. Secondary outcomes included general satisfaction with life, positive mood, sleep quality, and fatigue. Thirty‐one women with fibromyalgia participated in the randomized, double‐blind, placebo‐controlled, counterbalanced, crossover study. During the active drug phase, participants received 4.5 mg of oral naltrexone daily. An intensive longitudinal design was used to measure daily levels of pain. When contrasting the condition end points, we observed a significantly greater reduction of baseline pain in those taking low‐dose naltrexone than in those taking placebo (28.8% reduction versus 18.0% reduction; P = 0.016). Low‐dose naltrexone was also associated with improved general satisfaction with life (P = 0.045) and with improved mood (P = 0.039), but not improved fatigue or sleep. Thirty‐two percent of participants met the criteria for response (defined as a significant reduction in pain plus a significant reduction in either fatigue or sleep problems) during low‐dose naltrexone therapy, as contrasted with an 11% response rate during placebo therapy (P = 0.05). Low‐dose naltrexone was rated equally tolerable as placebo, and no serious side effects were reported. The preliminary evidence continues to show that low‐dose naltrexone has a specific and clinically beneficial impact on fibromyalgia pain. The medication is widely available, inexpensive, safe, and well‐tolerated. Parallel‐group randomized controlled trials are needed to fully determine the efficacy of the medication.

BACKGROUND The global obesity epidemic has paralleled a decrease in semen quality. Yet, the association between obesity and sperm parameters remains controversial. The purpose of this report was to update the evidence on the association between BMI and sperm count through a systematic review with meta-analysis. METHODS A systematic review of available literature (with no language restriction) was performed to investigate the impact of BMI on sperm count. Relevant studies published until June 2012 were identified from a Pubmed and EMBASE search. We also included unpublished data (n = 717 men) obtained from the Infertility Center of Bondy, France. Abstracts of relevant articles were examined and studies that could be included in this review were retrieved. Authors of relevant studies for the meta-analysis were contacted by email and asked to provide standardized data. RESULTS A total of 21 studies were included in the meta-analysis, resulting in a sample of 13 077 men from the general population and attending fertility clinics. Data were stratified according to the total sperm count as normozoospermia, oligozoospermia and azoospermia. Standardized weighted mean differences in sperm concentration did not differ significantly across BMI categories. There was a J-shaped relationship between BMI categories and risk of oligozoospermia or azoospermia. Compared with men of normal weight, the odds ratio (95% confidence interval) for oligozoospermia or azoospermia was 1.15 (0.93-1.43) for underweight, 1.11 (1.01-1.21) for overweight, 1.28 (1.06-1.55) for obese and 2.04 (1.59-2.62) for morbidly obese men. CONCLUSIONS Overweight and obesity were associated with an increased prevalence of azoospermia or oligozoospermia. The main limitation of this report is that studied populations varied, with men recruited from both the general population and infertile couples. Whether weight normalization could improve sperm parameters should be evaluated further.

The question of genetic alterations resulting from assisted reproductive technologies (ART) in humans is examined within the organization of the human genome. Increased rates of birth defects have been reported among children conceived using ART; however, questions remain and controversy exists regarding how "infertility" predisposes to birth defects. ART has been shown to be associated with an increased number of chromosomal alterations especially in the X chromosome. There is increased risk for embryonal tumors among ART conceived children, as well as, imprinting disorders (Beckwith-Wiedemann and Angelman Syndromes). Genetic studies of children conceived using ART reveal a larger (genome-wide) scale of methylation defects that encompass hundreds of genes. Genes involved in carcinogenesis and developmental pathways appear altered and may impact on later development of chronic illness, although these data are very preliminary. ART may create novel mutations by different chromosomal and molecular mechanisms; however, these techniques also enable propagation of pre-existing mutations that are associated with impaired fertility. While older maternal age is often associated with female infertility and chromosomal aneuploidy, sperm from older men have more new gene mutations. The prevalence of birth defects is increased when ART is used for conception. These data are summarized by large meta-analyses or from multi-year national registries. Whether the increased number of birth defects is due to ART procedures themselves or are a consequence of the impaired fertility of the parents is discussed. Long-term evaluation of children conceived using ART and/or ovarian hyper-stimulation is needed to determine whether alterations during embryonic development may increase the prevalence of chronic diseases in adulthood.
Marques-Pinto A et al., 2013·Endocrine connections
Over recent decades, epidemiological studies have been reporting worrisome trends in the incidence of human infertility rates. Extensive detection of industrial chemicals in human serum, seminal plasma and follicular fluid has led the scientific community to hypothesise that these compounds may disrupt hormonal homoeostasis, leading to a vast array of physiological impairments. Numerous synthetic and natural substances have endocrine-disruptive effects, acting through several mechanisms. The main route of exposure to these chemicals is the ingestion of contaminated food and water. They may disturb intrauterine development, resulting in irreversible effects and may also induce transgenerational effects. This review aims to summarise the major scientific developments on the topic of human infertility associated with exposure to endocrine disruptors (EDs), integrating epidemiological and experimental evidence. Current data suggest that environmental levels of EDs may affect the development and functioning of the reproductive system in both sexes, particularly in foetuses, causing developmental and reproductive disorders, including infertility. EDs may be blamed for the rising incidence of human reproductive disorders. This constitutes a serious public health issue that should not be overlooked. The exposure of pregnant women and infants to EDs is of great concern. Therefore, precautionary avoidance of exposure to EDs is a prudent attitude in order to protect humans and wildlife from permanent harmful effects on fertility.

Premature menopause affects 1% of women under the age of 40 years. The women are at risk of premature death, neurological diseases, psychosexual dysfunction, mood disorders, osteoporosis, ischemic heart disease and infertility. There is need to use simplified protocols and improved techniques in oocyte donation to achieve pregnancy and mother a baby in those women at risk. Review of the pertinent literature on premature menopause, selected references, internet services using the PubMed and Medline databases were included in this review. In the past, pregnancy in women with premature menopause was rare but with recent advancement in oocyte donation, women with premature menopause now have hoped to mother a child. Hormone replacement therapy is beneficial to adverse consequences of premature menopause. Women with premature menopause are at risk of premature death, neurological diseases, psychosexual dysfunction, mood disorders, osteoporosis, ischemic heart disease and infertility. Public enlightenment and education is important tool to save those at risk.
