OBJECTIVE
To evaluate endothelial function with flow-mediated dilatation (FMD) and carotid intima media thickness (IMT) in young nonobese polycystic ovary syndrome (PCOS) patients.
METHODS
Prospective case-control study.
METHODS
Healthy volunteers and nonobese young PCOS patients in clinical
Gynecomastia developed in three men 1-30 yr after the occurrence of testicular atrophy due to mumps orchitis. At the time of study, these men were 63-68 yr of age. In these men the mean plasma production rate of testosterone was 816 microgram/24 h, a value 20% of that found in normal elderly men
Androstenedione is an androgen steroid that is normally synthesized within men and women and may be metabolized to a more potent androgen or estrogen hormone. It was nominated to the National Toxicology Program for study due to concern for adverse health effects associated with its chronic use as a
OBJECTIVE
The aim of the study was to evaluate the laboratory and endometrial safety of topical testosterone versus topical estrogen for the treatment of vaginal atrophy in postmenopausal women.
METHODS
This was a randomized, placebo-controlled trial of 60 postmenopausal women aged 40 to 70 years at
The concentrations of androstenedione, testosterone and cortisol have been measured in the maternal peripheral plasma of normal pregnant rhesus monkeys (Macaca mulatta), and in rhesus monkeys treated daily with dexamethasone during late pregnancy. During the last 30 days of pregnancy, the mean
Interference with estrogenic and androgenic actions might result in an inhibitory effect of benign prostatic hyperplasia (BPH). In the present study the effects of the treatment of intact, adult beagle dogs with the antiandrogen cyproterone acetate (CPA) and the aromatase inhibitor 1-methyl-ADD
The present study explores the postulate that the polycystic ovarian syndrome (PCOS) is marked by failure of physiological feedforward and feedback signaling between pituitary LH and ovarian androgens. To this end, we appraised the 3-fold simultaneous overnight release of LH (assayed by high
The effect of sexual activity on vaginal atrophy was investigated in a group of 52 postmenopausal women (mean age, 57 years). Subjects were divided into two groups: sexually active (intercourse frequency, three or more times monthly) and sexually inactive (intercourse frequency, less than ten times
Women with Wilson's disease may have severe oligomenorrhea or amenorrhea whose cause is unknown. The endocrine profile of four such cases was investigated by measuring basal values and the response to dynamic tests of hypothalamic, pituitary, thyroid, and adrenal function, which all proved normal.
We report a 23-year-old man with mitochondrial encephalomyopathy. At 21 years of age, he noted speech distubance. Since his dysarthria did not improve thereafter, he was admitted to our hospital. On admission, he showed mild gynecomastia. Neurological examination revealed mild decrease in
Immature hypophysectomized (HYPOXD) rats develop large, polyfollicular ovarian cysts in response to unabated, combined stimulation by subovulatory doses of human chorionic gonadotropin (hCG) and highly purified ovine follicle-stimulating hormone (FSH). Further, circulating amounts of androstenedione
The fact that RU 486 curtailed estrogen-induced endometrial proliferation in primates and relieved pelvic pain in women with endometriosis is the reason for continuing research on antiprogestins. Thirty-two adult female cynomolgus monkeys demonstrating menstrual regularity had surgery for the
Testicular Leydig cells produce androgens essential for proper male reproductive development and fertility. Here, we describe a new Leydig cell ablation model based on Cre/Lox recombination of mouse Gata4 and Gata6, two genes implicated in the transcriptional regulation of steroidogenesis. The
Four patients with androgen insensitivity had plasma LH and FSH measured at 20-min intervals for 24 h and at 15- to 30-min intervals for 3 h after the injection of LRH. Twenty-four-hour mean testosterone (T), estradiol, and androstenedione (delta 4) levels were also measured. Patients with androgen
OBJECTIVE
In girls with congenital adrenal hyperplasia the degree to which excess androgen exposure leads to the development of prostatic tissue is largely uncharacterized, except in rare case reports of prostatic growth and adenocarcinoma. Such growth yields concern for future malignant
