The experience of the gynecologic endocrinology and infertility clinic at The Johns Hopkins Hospital has been subjected to a nonconcurrent prospective analysis in an attempt to evaluate the gestationa...

Lymphocyte reactivity was measured in human mixed lymphocyte (MLC) and mitogen-stimulated cultures in the presence of various steroids. When present during the entire culture period at concentrations ...

This study was designed to test the assumption that women with regular menstrual cycles and premenstrual symptoms are ovulatory. 40 women aged 20-40 years were selected as probably ovulatory on the ba...

NFP (natural family planning) has replaced the term of rhythm method in the last decade as a designation for those methods of fertility regulation based on periodic abstinence. A graph presents the sy...

This article describes the theory, methodology, and effectiveness of three natural methods of family planning: rhythm by calendar, strict basal body temperature rhythm, and combination calendar-BBT rh...

HYPOSPADIAS is a common anomaly of the urogenital system. The prevalence rate reported by various birth-defect monitoring programs shows a rather wide variation, ranging from about five per 10,000 to ...

Conflicting results have been published regarding changes in plasma progesterone during the last trimester of pregnancy. Some have demonstrated a fall in plasma progesterone before labor, and this has...

12 normal ovulatory women were studied during 17 menstrual cycles. The first day on which the women had increasing quantities of 0.1 ml or more clear cervical mucus (IQCCM) was closely related to the ...

Patients with two or more previous spontaneous second trimester abortions and vaginal cytology indicating a poor progestational response in current pregnancies were selected for treatment with Provera...

Pelvic adhesion formation represents a major problem following fallopian tube surgery for infertility. Intraperitoneal dextran may prevent pelvic adhesions. Extensive personal clinical experience (W. ...

The development of two groups of children whose mothers had been given progesterone supplements during pregnancy to relieve symptoms of toxaemia was assessed, one group at 2 yr of age and the other at...

Plasma progesterone, 17-hydroxyprogesterone, 20alpha hydroxypregn-4-en-3-one levels were determined twice weekly up to 16 weeks gestation, where possible, in a twin pregnancy, in two patients who abor...

Pip: The only way to be sure of avoiding pregnancy is for a couple to abstain from sexual intimacy during the fertile phase of the woman's cycle. Billings showed by reference to hormonal parameters th...

In rhesus monkeys with hypothalamic lesions that abolish gonadotropic hormone release by the pituitary gland, the constant infusion of exogenous gonadotropin-releasing hormone (GnRH) fails to restore ...

The observation of the "Peak" mucus symptom in women using the ovulation method of natural family planning has been correlated with the estimated time of ovulation, as evaluated by indirect hormonal p...
