Systemic lupus erythematosus characteristically afflicts women of reproductive age, yet the explanation for this feature is unknown. This hospital-based, case-control study of 109 incident cases of systemic lupus erythematosus and 109 randomly selected controls was conducted to search for risk factors related to reproduction. Women who were 34 years of age and younger had a crude risk of systemic lupus erythematosus 3.6 times that of older women, and women who were of minority races had a crude risk 4.8 times that of white women (P less than 0.001). Prior hysterectomy or tubal sterilization had a significant protective effect (odds ratio, 0.55; 95% confidence interval, 0.31 to 0.99). Endometriosis was associated with a twofold increased risk of systemic lupus erythematosus, although this was not statistically significant. The latter two findings are consistent with the hypothesis that retrograde menstruation may be an inciting factor for systemic lupus erythematosus in susceptible women.
The onset and progression through the various stages of puberty are influenced by a number of factors (Fig. 2). In both animals and humans, the age of puberty appears to be related more to body weight than to chronologic age. Undernutrition and low body fat, or an altered ratio of lean mass to body fat, seem to delay the adolescent spurt and to retard the onset of menarche. According to Frisch, a minimum level of fatness (17% of body weight) is associated with menarche; however, a heavier minimum weight for height, representing an increased amount of body fat (22%), appears necessary for the onset and maintenance of regular menstrual cycles in girls over 16 years of age. This critical amount of body fat implies that a particular body composition, in addition to other environmental and psychosocial factors, is important in triggering and maintaining the pubertal process.
A prospective six-year study (1975-1980) of 273 patients, monitored in the use of natural family planning (NFP), has shown that those with previously irregular menstrual cycles are disadvantaged in the subsequent use of the ovulation method after pregnancy in that they have fewer recognizable safe days and/or are more likely to have unplanned pregnancies than women who had regular cycles prior to pregnancy. Eight patients, seven nursing and one non-nursing mother, conceived during postpartum amenorrhoea. The reliability of memory in the recall of previous menstrual histories is discussed in relation to the results of an international study of menstrual cycles by the World Health Organization (WHO 1983). The relevance of prediction of menstrual events in natural family planning is also considered.

Human chorionic gonadotropin was administered intramuscularly in an open study of 32 women whose last three pregnancies had ended in spontaneous abortion. An initial dosage of 10 000 iu on earliest diagnosis of pregnancy was followed up by 5000 IU twice weekly up to wk 12, then once weekly up to wk 16. Only 2 of the 32 patients aborted (6.2%). Using the same regime a further 20 habitual aborters were randomly allocated double-blind to either hCG or placebo. All 10 women on active therapy continued (100%) compared with only 3 on placebo (30%) (P less than 0.01). These results suggest that hCG should be considered as treatment in women with habitual abortion where other specific causes have been ruled out and a potentially treatable hormonal imbalance surmised.
The likelihood of repetition of preterm birth after spontaneous onset of labour has been studied in 6572 reproductive careers after excluding stillbirths, multiple births, all careers in which any labour had been induced, and all careers in which the gestation length in any pregnancy was not certain. The analysis was controlled not only for pregnancy number, but for the nature of the reproductive outcomes. In most reproductive sequences there was a weak correlation between the gestation in one pregnancy and subsequent ones. The risk of preterm birth was tripled after one previous preterm birth with or without a preceding abortion, and increased six-fold after two previous preterm births. However, the attributable risk was low, and most multiparae with preterm births did not have a previous history.
The protective effect of progesterone or tamoxifen, an antiestrogenic agent, was investigated in estrogen-induced mammary carcinogenesis. Multiple mammary tumors (MT) of tubular or medullary carcinoma type developed at a high rate following prolonged treatment of ovariectomized W/Fu rats with diethylstilbestrol or 17 beta-estradiol. All MTs were located adjacent to the nipple and were slow-growing. The induction rate, multiplicity and size of estrogen-induced MTs were reduced by the simultaneous administration of either progesterone or tamoxifen. The estrogen-induced pituitary tumorigenesis was effectively inhibited by tamoxifen treatment, but it was not affected by progesterone. The results indicated that the inhibitory effect of progesterone or tamoxifen in estrogen-induced carcinogenesis is attributable to interference with the binding of estrogen to the estrogen receptors on the target cells.
A system capable of ambulatory home monitoring of uterine activity and data transmission was evaluated in a group of pregnant patients. The evaluation 1) Is the information as reliable as that obtained by the current stationary monitors; 2) Does the information obtained by the tested system relate to that obtained by direct intrauterine pressure measurements; and 3) Is the system simple enough to be used by the unsupervised gravida at home? The results indicate that the tested system can provide reliable information about uterine activity in ambulatory patients. A good correlation between the intensity of contractions and the recording of uterine activity by this system could be demonstrated, particularly in the presence of mild to moderate contractions. The tested monitor proved to be simple to use even in the untrained gravida. Additional studies to determine the role of ambulatory home monitoring of uterine activity in patients with cervical cerclage, placenta previa, and preterm labor will need to be performed to establish its role in current obstetric practice.
The medical records of 330 patients treated with terbutaline infusion for the inhibition of preterm labor were reviewed over a five-year period. In patients with intact membranes the results were uniformly good, particularly when treatment was instituted before the 30th week. Half these patients had a prolonged labor of six weeks or more; in most cases of treatment failure complications already existed on admission. In only nine patients (2.7%) terbutaline treatment was predominantly maternal tachycardia or vomiting. Two patients had chest symptoms, but in no case was pulmonary edema diagnosed. The results suggested that a low incidence of severe side effects can be obtained if the following glucose is used as the infusion medium, instead of sodium chloride; concentrated solutions are given to avoid fluid overload; the patients are carefully controlled; and the infusion is immediately reduced or stopped if signs of severe side effects appear.
In a consecutive series of 167 patients reaching the stage of embryo transfer after in vitro fertilization and embryo transfer, 19 clinical pregnancies ensued. The serum progesterone (P) levels were significantly greater on the first and second (P less than 0.01) and third (P less than 0.05) postaspiration days for those who conceived. Higher circulating levels of P were achieved on days 1, 2, and 3 (P less than 0.05) by the daily injection of P, 50 mg in oil, given for 5 consecutive days, beginning immediately after follicle aspiration. Both pregnancy and nonpregnancy cycles demonstrated high circulating P levels, but the study implies that relatively higher levels are required for conception, and such levels can be achieved by the use of intramuscular P.
To examine the site of action of clomiphene citrate (CC), LH and FSH pulsatile amplitude, frequency, and responsiveness to GnRH (10 micrograms, iv) were studied in 11 women during the early follicular phase of the menstrual cycle. Six women received CC (150 mg/day) on cycle days 2, 3, and 4, while 5 women received placebo tablets. Blood samples were drawn at 10-min intervals for 8 h before and after the treatment regimen on cycle days 2 and 5, respectively. All women treated with CC had multiple follicular development, as determined by ultrasound. Peripheral levels of estradiol did not change after CC treatment, while progesterone levels decreased slightly. Mean levels of LH increased from 7.5 +/- 0.9 (+/- SEM) to 10.7 +/- 1.4 mIU/ml (P less than 0.05), and FSH increased from 6.7 +/- 0.9 to 10.1 +/- 0.9 mIU/ml (P less than 0.01). After exposure to CC, the pulse frequency of LH during an 8-h period increased significantly (3.3 +/- 0.7 on day 2 vs. 6.8 +/- 0.8 on day 5; P less than 0.01), while the pulse frequency of FSH increased from 3.8 +/- 0.6 to 5 +/- 1.4, as determined by computer pulse analyses. The pulse amplitude of LH and FSH was not significantly altered. In the placebo-treated group, neither pulse amplitude nor pulse frequency changed significantly between cycle days 2 and 5. Pituitary sensitivity to exogenous GnRH did not change after CC treatment. Since the pulsatile frequency of LH is governed by hypothalamic influences, these findings provide compelling evidence for a hypothalamic site of action for CC, probably by inducing an increase in the frequency of GnRH secretion.
Gonadal steroids are altered by the reproductive system's adaptation to conditioning exercise. Contraceptive options for the athletic woman include all measures appropriate for the sedentary woman. Barrier methods (always with spermicidal jelly) are the preferred choice. The cardiovascular risks, decreased aerobic performance, and shorter time to muscular exhaustion related to oral contraceptives make this a less desirable option. Potential complications from the steroid changes low oestrogen and progesterone with risk of loss of trabecular bone and early osteoporosis, and absent progesterone with low normal oestrogen levels associated with risk of endometrial or breast cancer. Therapeutic options for the amenorrhoeic or young athlete include supplemental oral calcium, cyclic oral progesterone, or possibly cyclic physiological oestrogen and progesterone. The anovulatory (usually older) athlete with regular menses needs cyclic progesterone. Medroxyprogesterone 10mg on days 16 to 25 of the cycle or for 10 days monthly can potentially prevent endometrial and breast cancer, give predictable cycles, improve trabecular bone balance and stimulate the return of ovulatory cycles. A practical approach to anovulatory infertility in the athlete includes a 10% reduction in exercise intensity and/or an increase in percentage body fat to 18 to 20%. Cyclic vaginal progesterone (25mg bid) can then treat short luteal phase cycles. With improved understanding of the hormonal adaptations to conditioning exercise, we will be better able to outline contraceptive and therapeutic options in the future.
General OB/GYNUnusual PresentationsEstrogen-InducedAdverse Effects
An 83-year-old man with an endometrioma of the lower abdominal wall has been reported. This occurred following the administration of 25 mg of TACE for a period of about 10 years for what was thought to be carcinoma of the prostate. A second transurethral resection done by Dr. R. C. Thompson proved to be adenocarcinoma. Subsequent to this he was continued on TACE. A review of the more commonly accepted theories of the development of endometriosis in the female has been presented. It is pointed out that the separation between the male and female urogenital systems occurs in the embryo between the eighth week and the fourth month. There is always a possibility for remnants of the opposite sex to remain in individuals. No such was seen in the case which is herein reported. Normal phenotype male was demonstrated in the chromosomal evaluation. A review of the literature on endometriosis in the male reveals several cases which have occurred; the origin of which is though to be from the prostatic utricle which is a remnant of the uterus existing in the male. After a prolonged course the patient reported was followed until he died in 1979. There was no recurrence of the abdominal wall mass but persistent low grade carcinoma of the prostate remained. The terminal process was related to cardiovascular disease and not carcinoma of the prostate. There was delay in publication of this unusual case. The original plan was to await final confirmation of the exact pathologic nature of this condition; unfortunately this was never done since a postmortem examination was not performed.(ABSTRACT TRUNCATED AT 250 WORDS)
This report presents the outcome of pregnancies of 93 women who conceived while taking progesterone (P) suppositories (n = 42) or P in oil intramuscularly (n = 51). The dosage and duration of treatment varied according to the indication. The total dose (in milligrams) increased with the duration of treatment and ranged from 75 to 13,500 mg. Two of 75 term pregnancies (2.6%) were noted to have congenital anomalies. Both women had been treated with P in oil. No patient treated with P suppositories gave birth to a malformed infant. An increased spontaneous abortion rate (28.6%) was noted among women treated with P suppositories. The authors recommend that a national registry be created to document fetal outcome after P therapy.
Molloy AM et al., 1985·Archives of disease in childhood
Serum folate and vitamin B12 concentrations in early pregnancy were compared for 32 mothers with pregnancies affected by neural tube defects and 395 randomly selected pregnant control women from the same maternity hospitals. No significant differences were found between the affected mothers and the controls in the median values and frequency distributions of either vitamin. Sixteen of the samples from mothers whose infants had neural tube defects were taken between 9 and 13 weeks' gestation and 11 of these had both serum folate and vitamin B12 concentrations within the normal ranges for our laboratory. These findings are discussed in relation to the concept of folate deficiency as a major factor in the aetiology of neural tube defects.
Substantial evidence now exists to indicate that the endogenous hypothalamic opioidergic mechanism(s) represents one of the important controlling systems for release of gonadotropin-releasing hormone. Modulations of frequency and amplitude of the secretory activity of gonadotropin-releasing hormone appears to be mediated through an inhibitory action of endogenous opioids, and the functional coupling of the opioidergic and gonadotropin-releasing hormone systems is an ovarian steroid-dependent event. There is also evidence to implicate suprahypothalamic mechanism(s) that enhance endogenous opioid inhibition of secretion of gonadotropin-releasing hormone. Although exogenous opioid peptides and their synthetic analogs consistently induce the secretion of prolactin, blockade of opioid receptors in humans by naloxone failed to elicit a decrement in the levels of prolactin under a variety of conditions. On the contrary, naloxone induced a remarkable increment in the secretion of prolactin via an increased frequency of pulsatile release which is synchronized with pulses of luteinizing hormone. These observations suggest that a common neuroendocrine mechanism is involved in the opioidergic control of the secretion of both luteinizing hormone and prolactin in women.
InfertilityOvulatory DysfunctionCombined Ultrasound and Hormonal MonitoringLuteinized Unruptured Follicle
We have examined for the presence of subtle hormonal abnormalities in women with long-standing unexplained infertility. For a full cycle serum LH, FSH, progesterone and oestradiol levels were measured about three times a week, and serial ultrasound scans of the ovaries made until the time of apparent ovulation. The results on 45 cycles in 35 women with unexplained infertility and in three normal volunteers are presented. Normal ovulatory cycles were defined by a length of 26-32 d, and progressive follicular maturation followed by disappearance or abrupt reduction in size of a follicle within 48 h of the recorded LH peak, followed by progressive and sustained rise in serum progesterone levels to more than 25 nmol/l and a luteal phase length of greater than or equal to 13 d. Thirty spontaneous cycles (28 women) were clearly normal while 15 spontaneous cycles (12 women) were abnormal. Abnormalities included luteinization of an unruptured follicle (eight cycles), absence of follicular development (two cycles), poor follicular development (two cycles), persistence of a large ovarian cyst from the preceeding cycle (two cycles) and one aluteal cycle. Six of the abnormal cycles were characterized hormonally by inappropriate elevation of serum LH levels throughout. If this study had been based only on serial ultrasound scans, all results on abnormal cycles might have been misinterpreted. If it had been conducted only with (multiple) progesterone determinations and the level of greater than 25 nmol/l had been taken as indicative of ovulation nine clearly abnormal cycles would have been considered as normal. We conclude that the combination of the hormonal and ultrasound assessment of ovulation increases our confidence for confirmation of normality and reveals various ovulatory disorders which are possibly due to an endocrinological defect or defects.
PCOSHirsutism TreatmentAntiandrogen TherapyCombination Drug Therapy
Clinical and laboratory evaluations of nine hirsute women were performed for determination the efficacy of combination drug therapy. Each patient had previously failed to respond to single drug therapy with oral contraceptives (OC), dexamethasone (DEX), or spironolactone (S) and received S (100 to 150 mg) and either an OC (mestranol, 0.05 to 0.08 mg, and norethindrone, 1 mg) or DEX (0.5 mg) daily. Total testosterone, dehydroepiandrosterone sulfate, free testosterone, and sex-hormone-binding globulin were measured before therapy and 4 to 6 weeks after initiation of therapy and were compared with the responses to OC (n = 7), DEX (n = 8), and S (n = 6). A satisfactory clinical response in the rate of hair growth was defined as at least a doubling of the time interval between adjunctive therapies (electrolysis, shaving, or bleaching) and patient satisfaction with treatment. The responses of the androgenic parameters were not statistically different between combination and single drug therapy. Although all patients noted a subjective improvement in hair growth, eight of nine fulfilled the criteria for a clinical response (P less than 0.001). Transient diuresis was the only side effect noted. The study suggests that combination drug therapy is an efficacious and well-tolerated approach to the management of unresponsive hirsutism.
A double blind, randomised, crossover trial of oral micronised progesterone (two months) and placebo (two months) was conducted to determine whether progesterone alleviated premenstrual complaints. Twenty three women were interviewed premenstrually before treatment and in each month of treatment. They completed Moos's menstrual distress questionnaire, Beck et al's depression inventory, Spielberger et al's state anxiety inventory, the mood adjective checklist, and a daily symptom record. Analyses of data found an overall beneficial effect of being treated for all variables except restlessness, positive moods, and interest in sex. Maximum improvement occurred in the first month of treatment with progesterone. Nevertheless, an appreciably beneficial effect of progesterone over placebo for mood and some physical symptoms was identifiable after both one and two months of treatment. Further studies are needed to determine the optimum duration of treatment.
Possible teratogenic effects of exogenous progestational agents given during early pregnancy were investigated by a controlled historic prospective study of 2754 infants born to mothers who had bled during the first trimester of pregnancy. The study group consisted of 1608 newborns whose mothers had been treated with progestogens (mostly medroxyprogesterone acetate) beginning in the first trimester. The control group comprised 1146 infants of untreated mothers. All newborns were subjected to thorough examination during the first days of life, with special attention to detection of various malformations classified according to the different anatomic systems. No significant difference was found between the treated and the control groups with respect to malformations in any of the systems examined. The overall rate of malformations was 120 per 1000 in the study group and 123.9 per 1000 in the control group. Major malformations occurred at rates of 63.4 and 71.5 per 1000, respectively. The study thus fails to demonstrate an increase in teratogenicity after administration of gestagens during the first trimester of pregnancy.
This study examined the characteristics and attitudes of 132 married couples who had received training in use of the symptothermal method of natural family planning (NFP). 61% of respondents were 20-30 years of age and over 2/3 had completed college; 59% were Catholic. The largest group of subjects (35%) became aware of NFP through friends, neighbors, and relatives. 71% said they were drawn to NFP because it represented a safe and healthy alternative to other methods of birth control; only 17% gave moral or religious reasons for learning about NFP. 42% of the sample were using NFP at the time of the survey, 32% had discontinued use, and 25% were using fertility awareness in conjunction with barrier methods (combination-continuers). There was a significant difference between these 3 48% of combination-continuers and 67% of continuers compared with 41% of discontinuers attended church once a week or more. The combination-continuer group had more Catholics (50%) than the discontinuer group (37%) but less than the continuers (76%). No significant differences were found between the 3 groups in terms of age, education, or regularity of menstrual cycle length. Over 3/4 of continuers had been married for less than 5 years compared with about 1/2 of those in the 2 other groups. 69% of continuers believed that NFP is extremely effective compared to 13% of discontinuers and 40% of combination-continuers. Spouses encouraged each other in the use of NFP in 88% of combination-continuer couples and 86% of continuer couples, but only about half of discontinuers received such encouragement. Although most NFP advocates emphasize a nonsexual form of abstinence during the fertile period, the vast majority of respondents in this study defined abstinence to include the possibility of orgasm. Combination-continuers, positioned between continuers and discontinuers or both dissatisfaction with other methods and with abstinence, warrant more attention in future NFP research.
InfertilityDiagnosis and AssessmentEndometrial Biopsy HistologyProgesterone Insufficiency
Endometrial biopsy specimens were obtained from 107 normally menstruating infertile women 2 to 3 days before the anticipated onset of menses and were day-dated according to histologic criteria. A simultaneous blood sample was obtained for measurement of progesterone (P) and beta-subunit of human chorionic gonadotropin. Of 98 biopsies which could be accurately dated, 56 were in-phase (IP) and 42 were out-of-phase (OOP). Mean serum P levels were significantly lower in women with OOP biopsies undertaken more than 4 days before the onset of menses. A sharp decline in serum P levels was observed in women with IP but not OOP biopsies, so that on the final premenstrual day serum P levels were significantly higher than normal in women with OOP biopsies. Pregnancy continued without interruption in two of six patients who underwent biopsy in the cycle of conception. One patient had an ectopic pregnancy; and the three remaining pregnant patients, all with subnormal P values, aborted. The study suggests that there is a high frequency of minor abnormalities in luteal function in normally menstruating, infertile women for whom tubal and male factors were normal. The frequency of subclinical pregnancy (2 of 107) was lower than anticipated from earlier studies.
The current status of natural family planning (NFP) was reviewed. There is renewed interest in NFP, and many couples who find other methods unacceptable for medical, safety, or personal reasons are turning to NFP methods. The percent of contraceptive users who rely on behavioral methods in developing countries in 35% in Peru, 20%-25% in Haiti, Philippines, and Sri Lanka, and average 7.5% for the remaining 23 developing countries. IN the US about 4.7% of all contraceptive users rely on behavioral methods. Worldwide, rhythm is the most commonly used form of behavior fertility control, but this method is not promoted by most NFP programs. The 3 modern methods of NFP are 1) the basal body temperature method, 2) the cervical mucus, or Billings method, and 3) the sympto-thermal method. All these methods rely on physical signs and symptoms to detect ovulation and require sexual abstinence during the fertile phase of the menstrual cycle. The basal body temperature method requires women to detect the slight rise in temperature which occurs at the time of ovulation. The method is 94%-97% effective if intercourse is restricted to the postovulatory phase of the cycle. Disadvantages of the method are that intercourse must be restricted to only 7-13 days of the cycle, women must take their temperature daily, the method cannot be used during fever episodes, and the method is inappropriate for use during lactation or near menopause. The cervical mucus method is based on observing cervical mucus changes during the cycle. These changes signal the fertile and infertile phases of the cycle. According to a World Health Organization study, 93% of the women instructed in the method were able to detect mucus changes, and illiterate women were as adept at identifying these changes as university graduates. Findings also indicated that the method was 97% effective if abstinence was practiced during 15 days of the cycle, but use-effectiveness was only about 80%. This method has the advantage of not requiring ovulatory regularity. The sympto-thermal method uses a combination of symptoms including temperature shifts and mucus changes to detect ovulation. Some studies indicate that the combined method is more effective than those methods based on only 1 symptom, but many individuals find the combined method difficult and confusing. The advantages of NFP methods are that they require no medical supervision and that they have no side effects. Family planning providers often have negative attitudes toward NFP and many programs do not provide NFP services. Many providers maintain that the methods are ineffective and difficult to apply and that there is little demand for NFP. Research should be undertaken to determine if these opinions are valid. The major source of funding for NFP programs and projects is the US Agency for International Development (USAID). The agency is currently supporting 22 NFP projects under USAID grants and another 16 bilateral NFP programs. The research undertaken in connection with these projects should provide needed information on NFP advantages, disadvantages, effectiveness, and demand.
A prospective longitudinal and standardized study is presented, dealing with ultrasonographic and hormonal characteristics of the luteinized unruptured follicle (LUF) syndrome. Among 600 cycles monitored in 270 infertility patients, 40 cycles in 27 patients showed no evidence of follicle rupture, in spite of signs of luteinization, as reflected by basal body temperature recordings and progesterone determinations. In this study, 20 LUF cycles in 20 infertile patients were compared with 45 ovulatory cycles in 45 control women. During the follicular phase, no substantial difference in follicle growth was found, but after the luteinizing hormone peak, LUF follicles, instead of rupturing, showed a typical accelerated growth pattern. Both mean luteinizing hormone peak levels and midluteal progesterone levels were significantly lower in LUF cycles than in the control cycles. However, the duration of the luteal phase was not affected. Both central and local factors can be held responsible for the lack of follicle rupture. Ultrasound offers new possibilities as a noninvasive method in diagnosing the LUF syndrome.
General OB/GYNSchool-Based Reproductive Health ServicesAccess and UtilizationTeen Pregnancy Prevention Programs
School-based clinics that provide contraceptive services to teenagers are proving 2 the more accessible birth control services are, the more young people will use them; and when those services are used, births among teenagers will decrease. During a recent meeting of the National Family Planning and Reproductive Health Association in Washington, D.C., representatives of successful school-based programs outlined their strategies for starting clinics. A spokesperson for the US Public Health Service talked about obtaining funds for such programs. Officials agree that school-based clinics are likely to be successful only when they offer family planning services as part of a comprehensive health care clinic. Currently, about 14 providers operate 32 school-based clinics around the country. The Jackson-Hinds Community Health Center of Jackson, Mississippi has established clinics in 5 public schools, 1 rural high school, and 1 urban junior high school. In 1979, the center reached about 18,000 people in a target population of 61,000. When the health center established the clinic in the 1st high school in 1970 and began gathering preliminary information on the school's 960 students, clinicians identified 90 adolescents who were already mothers. The 1st step was to enroll 52 of the teenage mothers in a special program. The health center's community board played a key role in establishing the clinics. The Jackson clinic program falls under the auspices of the medical establishment. Other similar programs have been organized by medical schools, family planning agencies, and even school districs. According to Joy G. Dryfoos, a private consultant who works with the administrators of many school-based clinics, some programs have nomedical roots, including the school-based programs initiated by Urban Affairs Corporation, a private, nonprofit group in Houston, Texas. Sharon Lovick, former executive administrator of the operation, was involved in starting a $900,000 school-based clinic program in Houston Public Schools. The program started in 1981 with a strong middle school orientation. Its initial service was day care for children of teenage mothers. The Jackson and Houston programs shared some of the same initial experiences, but their clinic locations, organization, and funding differed. An inportant aspect of both programs is clinic organization. Every teenager who receives contraceptives from the programs' clinics is contacted once a month by a staff person. The long range objective is to have a nurse practitioner at each school clinic. The program relies on many young physicians who are just completing their training. In Houston trasportation is the key element. The adolescents are picked up and brought to the clinic during the school day. Each visit a family planning patient makes to the Houston school-based clinic involves a group experience. A family planning advocate works specifically with young women in the family planning program. Ways to pursue funding for school-based clinics are outlined.
One case of extensive endometriosis with ascites in a young nulliparous woman is reported. The patient had been maintained on suppressive therapy with danazol for over two years, demonstrating the feasibility of conservative management in this extremely rare form of endometriosis. However, long-term efficacy and potential for fertility remain to be determined.
Comparison of a cohort of 988 offspring exposed in utero to exogenous progestins with a matched cohort of unexposed offspring did not result in detection of an association of congenital anomalies with exposure. The conclusions are based primarily on outcomes of pregnancy with exposure to progesterone and 17 alpha-hydroxyprogesterone caproate, and may not apply to androgenic progestins. Offspring exposed to combinations of progestins and estrogens were excluded from this study and may have a different distribution of anomalies.
Fertility AwarenessReturn of FertilityLuteal Phase AbnormalitiesPostpartum Monitoring
Luteal phase abnormalities in early menstrual cycles after pregnancy have been shown to cause confusion in the practice of natural family planning (NFP) for some patients and to restrict severely the number of late infertile days available to others. The cause of the abnormalities is uncertain but appears to be related to the nursing status of the patient.
Eighty pregnant women at high risk of giving birth prematurely were divided randomly into two groups. Treatment with either 17 alpha-hydroxyprogesterone caproate, 250 mg by intramuscular injection once a week, or a placebo was given in a double-blind fashion. Imminent premature labor occurred in 29.0% of the treated group and in 59.4% of the control group (p less than 0.025). The rate of premature deliveries was also significantly lower in the treated group (16.1%) than in the control group (37.82%) (p less than 0.05). There were no cases of perinatal death or fetal malformations in either group. The mean birth weight of all infants of the treated group was significantly higher than in those of the control group (3111.9 +/- 905 gm versus 2680 +/- 813.4 gm, p less than 0.05). The results support treatment with progesterone caproate for the prevention of premature labor.
Serum hormone concentrations were determined at intervals during the last 17 days of the menstrual cycle in 35 patients with premenstrual tension (PMT) and 11 control subjects without symptoms. The maximum mean concentration of oestradiol occurred 17 days before menstruation in the patients and 14 days before in the controls. The maximum concentrations of progesterone were similar in the two groups but the mean concentrations rose earlier in the cycle in the patients with PMT. These results suggested that the patients tended to ovulate earlier in the cycle than the controls and on the basis of the ovulatory surge in gonadotrophins two groups could be identified, group A who showed signs of ovulation 14 days or less before menstruation (17 patients, 9 controls) and group B who ovulated more than 14 days before menstruation (18 patients, 2 controls). There were no significant differences between the groups in prolactin, thyroid stimulating hormone or testosterone levels, but cortisol concentrations were uniformly higher in both groups of patients compared with those in the controls. Follicular growth was assessed with ultrasound in 18 patients and 16 control subjects. Mean follicular diameters were significantly lower in the patients than in the control group at the time of ovulation. Oestradiol determinations done at the same time correlated with the diameters and were also significantly lower in the patient group. The results suggest that ovulation tends to occur prematurely in women with PMT.
The plasma concentrations of medroxyprogesterone acetate (MPA) in 14 women administered the progestagen for threatened abortion during the first 6 weeks of pregnancy were measured by specific radioimmunoassay. Treatment (52 nmol orally every 6 h) was continued to 18 weeks of gestation. The mean plasma concentration of MPA rose rapidly during day 1 of treatment to 14.1 +/- 1.84 nmol/l. It reached 21.5 +/- 2.3 nmol/l by 7 days and subsequently stabilized at around 26.8 +/- 5.0 nmol/l by the end of week 2. Urinary steroid profiles were determined by gas-liquid chromatography and mass spectrometry for six of the MPA-treated women and compared with those of six untreated women of similar gestational age. No differences were detected between the two groups of women, suggesting that the administration of MPA during pregnancy did not alter qualitatively or quantitatively the metabolism and excretion into urine of progesterone and oestrogens.
Fertility AwarenessMethod ComparisonUltrasound vs BiomarkersDonor Insemination Timing
Ninety-five menstrual cycles were studied in 20 women undergoing donor artificial insemination (AID). In 49 cycles basal body temperature (BBT) changes were charted daily and both daily cervical mucus scoring (modified Insler score) and daily realtime ultrasonography (USS) were performed from day 11 to ovulation. AID was performed only on the day of follicular rupture. A control group, not subjected to USS, were inseminated two to three times per cycle over 46 cycles in the periovulatory period. The Insler score was found to be a reliable indicator of follicular development and rupture. The BBT was found to be less reliable than the Insler score or USS. While USS may be used to confirm follicular development, the Insler score is reliable and less costly.
Menstrual CycleAnovulation and Luteal DefectsMenstrual DysfunctionReproductive Impact
Sonographic criteria of endometrial tissue were obtained following serial observations in normally ovulating women, and a prospective identification of a specific phase was made in those with regular menstrual cycles. This may be the first report of endometrial tissue characterization. Clinical management of infertility and monitoring of follicular growth will thus be facilitated.
Barely 13 years after its initial discovery, the hypothalamic luteinizing-hormone releasing hormone (LHRH) appears to be claiming a large territory in clinical medicine. "There's almost no subspecialty of medicine that will be left untouched by the [research] advances associated with LHRH or its analogues," predicts William F. Crowley, MD, associate professor of medicine at Harvard University Medical School, Boston. He points out that this polypeptide hormone (also known as gonadotropin-releasing hormone or GnRH) is already providing new treatments for several human diseases and "represents one of the examples where an investment in basic science has profound clinical applications." Crowley, who is also chief of reproductive endocrinology at the Massachusetts General Hospital in Boston, discussed the therapeutic implications of LHRH and its analogues at the Seventh International Congress of Endocrinology in Quebec City. So far, he says, the ability of LHRH to either stimulate or suppress reproductive processes has been applied
In a placebo controlled, double blind crossover study natural progesterone was given by mouth, in increasing doses, to six men and four postmenopausal women with mild to moderate hypertension who were not receiving any other antihypertensive drugs. When compared with values recorded before treatment and during administration of placebo progesterone caused a significant reduction in blood pressure, suggesting that progesterone has an antihypertensive action rather than a hypertensive one as has been previously thought. This possible protective effect of progesterone should be investigated further.
Plasma and erythrocyte magnesium were measured in 105 patients with premenstrual syndrome (PMS) using a simple atomic absorption spectroscopy method. The erythrocyte magnesium concentration for the patients with PMS was significantly lower than that of a normal population. The plasma magnesium did not show this difference. The significance of this apparent cellular deficiency of magnesium is discussed.
Excised tubal segments from 42 women with uterotubal junction obstruction were studied histologically to evaluate the pathologic spectrum of disease and correlate this with clinical data. The most frequent lesion encountered was obliterative fibrosis (38.1%), confirmed by connective tissue stains, which was not associated with cornual nodularity. Other pathologic entities included salpingitis isthmica nodosa (23.8%), intramucosal endometriosis (14.3%), and chronic tubal inflammation (21.4%). Intramucosal endometriosis was distinguishable from salpingitis isthmica nodosa by virtue of its unique stroma confirmed by connective tissue staining. Women with previous pregnancies were included in all the groups. In all instances, the obstruction was present in the transmural portion of the tube and extended a variable distance into the isthmic segment. These observations on uterotubal junction 1) There are multiple distinct histologic patterns, 2) Intraabdominal findings do not predict the histology of the uterotubal junction pathology, 3) Any histologic pattern can be associated with a previous intrauterine or ectopic pregnancy, and 4) The obstruction begins within the transmural portion of the oviduct, extends a variable distance into the isthmic segment, but does not obstruct the ampullary segment. These data suggest that the initiating process originates within the uterus and that fibrosis may represent a nonspecific response to chronic injury of the transmural and isthmic segments of the oviduct.
Fifteen women with moderate to severe premenstrual symptoms, defined and graded according to a recently developed scoring system, took part in a double blind study of the effect of progesterone on premenstrual symptoms. The dosage was 100 mg progesterone twice daily delivered in vaginal pessaries. The women were improved with a statistically significant decrease in their scores by progesterone as well as by placebo treatment. There was no statistically significant difference between the two regimes.

Eighteen women with cervical ectropion and 12 women with ectropion and vaginal discharge were treated by cryosurgery. Evaluation of the cervical mucus characteristics by cervical score and in vitro penetration test was performed before treatment and 2 months later. In the group with ectropion only (group A) the total cervical score was 5.7 +/- 0.4 and 11.9 +/- 0.06 (P less than 0.001) (mean +/- standard error) before treatment and 2 months later, respectively. In the group with ectropion and vaginal discharge (group B) the total cervical score before and after cryosurgery was 3.8 +/- 0.4 and 11.8 +/- 0.1 (P less than 0.001), respectively. In vitro penetration tests in group A before and after treatment were 0.72 +/- 0.1 and 2.9 +/- 0.08 (P less than 0.001), respectively. In group B, in vitro penetration tests before and after cryosurgery were 0.25 +/- 0.1 and 2.8 +/- 0.1 (P less than 0.001), respectively. It appears that cryosurgery improves the cervical mucus characteristics. It is recommended that infertile patients with hostile cervical mucus and ectropion will be treated by cryosurgery.
The intraperitoneal instillation of 32% dextran 70 (HyskonR, Pharmacia AB, Sweden) has previously been reported to prevent the formation of postoperative adhesions. Against this background, the present study was undertaken to evaluate the efficacy of HyskonR in counteracting peritoneal adhesions following tubal microsurgery. 105 infertile women were operated upon in a prospective, randomized, controlled, double-blind, multicenter study. The intra-abdominal adhesions present from the beginning were classified by means of a standardized scoring scale and the extent of adhesions was again evaluated at follow-up laparoscopy 4-10 weeks later. A reduction in the extent of the intra-abdominal adhesions (statistically highly significant) was revealed in both the Hyskon group and the saline control group. The extent of adhesions in the Hyskon group was not lesser than in the saline group, however. The pregnancy rates in the two groups were also similar.
An in vitro bioassay for lactogenic hormones, based on the specific mitogenic effects of lactogens on cultured Nb2 node rat lymphoma cells, was used to measure the levels of lactogens in whole serum and in fractionated serum samples from three patients with prolactin (PRL) secreting pituitary adenomas. Under basal conditions, after pituitary stimulation, and following treatment with bromocriptine which greatly decreased the serum PRL levels, the bioassay (BA) results closely paralleled fluctuations in the sum of radioimmunoassay (RIA) estimates of serum PRL and growth hormone concentrations. The extreme sensitivity (10 pg/ml) of the BA facilitated measurement of PRL in fractions obtained after Sephadex G-100 chromatography of only 0.1 to 0.3 ml of sera from both untreated and bromocriptine-treated prolactinoma patients. In both types of samples, similar heterogenous patterns of bioactive PRL were observed, although most of the recovered activity appeared to be due to monomeric PRL. BA and RIA of fractions obtained after DEAE cellulose chromatography of sera from untreated prolactinoma patients revealed two PRL peaks, the first one containing 75% of the activity. Therapy with bromocriptine led to a reduction in the total serum PRL activity and, in particular, in the activity of the second peak.
