In eumenorrheic women with endometriosis and in oligo-amenorrheic women with polycystic ovarian disease (PCO), chronic administration of a long-acting GnRH agonist (GnRH-a) reduced the circulating concentrations of estrogens and androgens t…

Although several drugs with antiandrogenic properties have been used to treat such conditions as prostatic carcinoma, precocious puberty, acne, and hirsutism, their relative strengths in human tissues are not known. Most of the compounds th…

This study was designed to test the efficacy of a long-acting GnRH agonist (alpha) for inhibition of ovulation and menses in monkeys as well as suppression of mild to moderate endometriosis through an individualized, intermittent regimen. E…

To examine the relationship between the occurrence of menopausal hot flashes and the pulsatile release of LH, we have investigated the serum hormone levels and the occurrence of hot flashes by objective recordings in five women with endomet…

The regulation of PRL release from chorion-decidual explants was evaluated in organ cultures. Agents previously shown to stimulate pituitary release in vitro (TRH, theophylline, estradiol, and vasoactive intestinal polypeptide) were all wit…

A 30-year-old patient with primary infertility had a history of recurrent oral and perineal rashes that appeared just prior to the midcycle rise in basal body temperature and subsided with the onset of menses. The rashes did not appear duri…

Five women with endometriosis were given a daily dose of a potent long-acting GnRH agonist, D-Trp6-Pro9-Net-LHRH (GnRH-A) for 28 days in an attempt to suppress ovarian estrogen secretion. The mean level of estradiol (E2) during sampling ove…

Seven healthy women, aged 21–36 yr, were treated with metoclopramide (MC; 10 mg 3 times daily orally) from the 2nd to the 22nd cycle day over 2 consecutive menstrual cycles in order to investigate the effects of hyperprolactinemia on female…

An ovarian perifusion technique was used to determine if there is a direct suppressive effect of PRL on human gonadal steroid secretion. Ovarian tissue from nine patients was examined. Ovine PRL (0.1-10 IU/ml) directly suppressed progestero…

The synthetic steroid, danazol [17 alpha-pregna-2,4-dien-20-yno-(2,3,d)isoxazol-17-ol], is used widely for the treatment of endometriosis. In nine subjects studied over a 6-month course of treatment and for 5 months subsequently, plasma hig…

Danazol (a derivative of 17 alpha-ethinyl testosterone) has recently been reported to cause clinical exacerbations of acute intermittent porphyria. In the present study, we demonstrate that danazol is an inducer of hepatic delta-aminolevuli…

This report describes the binding of 70 synthetic compounds to both testosterone-binding globulin (TeBG) and corticosteroid-binding globulin (CBG). The ability of each compound to displace [3H]testosterone from TeBG and [3H]cortisol from CB…

Peritoneal fluid was collected at laparoscopy in women during the menstrual cycle and was assayed for protein and steroid hormone content. The total protein concentration in peritoneal fluid and the concentrations of the steroid hormone-bin…

Analysis of 25 plasma proteins was performed on blood drawn from 7 females before and during treatment with danazol. This steroid was found to induce a pattern of plasma protein changes similar to but not identical with that of other 17 alp…

Acute intermittent porphyria (AIP) is a disorder of porphyrin metabolism in which the basic defect is a partial deficiency of uroporphyrinogen I synthase. The clinical disorder is more common in women, and some experience acute attacks befo…

A 23-yr-old woman whose initial complaint was infertility demonstrated glandular stromal dissociation with failure of the endometrial stroma to undergo pseudodecidualization in repeated endometrial biopsies taken late in the luteal phase. A…

Calcium metabolism during the menstrual cycle was studied in seven women from whom fasting blood samples were drawn daily or every other day throughout ovulatory cycles. Total calcium (Ca), ionic calcium (Ca++), magnesium (Mg), phosphorus (…

The clinical courses of galactorrhea and menstrual disorders were studied in 18 women with galactorrhea induced by sulpiride (SLP) or metoclopramide (MCP) given for the treatment of gastrointestinal diseases. The response of PRL and TSH to …

Spontaneous ovarian activity, as reflected by the urinary excretion of total estrogen and pregnanediol measured serially (thrice weekly) over a period of 3-4 months, was studied in nine young women (15-27 yr old) with a history of dysfuncti…

Progesterone binding by 100,000 X g cytosols of human myometria from patients undergoing hysterectomy for various reasons was assayed using equilibrium dialysis or DEAE-cellulose filtration. The estimates of high-affinity porgesterone bindi…

The dynamics of estrogen secretion and production were studied using isotope dilution techniques combined with direct sampling of ovarian venous blood and follicular fluid in 10 women with a clinical history of anovulatory dysfunctional ute…

An iv infusion of prostaglandin E2 (PGE2) was given for 8 hr on 2-3 consecutive days to 7 normally cycling women during various periods of the luteal phase, and to 1 woman whose luteal phase was prolonged by hCG administration. Three women …

The effects of an ethinyl testosterone analogue, 17α-pregn-4-en-20-yno-(2,3-d) isoxazol-17-ol (Danazol), on the pituitary-testicular function of normal males are described. This compound has been shown to have an impeded androgenic effect i…

The role of the uterus in the maintenance and regression of the corpus luteum was investigated in 7 patients who underwent hysterectomy for leiomyomata. Except in one patient, hysterectomy was performed in the postovulatory phase of the cyc…
