Active clinical trials for "Hyperandrogenism"

Women with PCOS suffer from anovulation and, as a result, infertility. Efforts to clinically induce ovulation in these women using follicle stimulating hormone (FSH) administered subcutaneously seemingly requires prolonged administration compared to that of ovulatory women without PCOS. The apparent differing ovarian responsiveness to FSH between PCOS and normal women has not been carefully studied. We propose to address this issue by performing a dose-response study and examine ovarian follicle (estrogen, E2) responses to FSH administered subcutaneously in women with PCOS compared to responses observed in normal women.

Many, but not all, girls with high levels of the male hormone testosterone go on to develop polycystic ovary syndrome (PCOS) as adults. Women with PCOS often have irregular menstrual periods, excess facial and body hair, and weight gain. PCOS is also a leading cause of difficulty becoming pregnant. The investigators do not understand why some girls with high hormones develop PCOS and others do not. In a previous study by our group, some girls with high levels of male hormones had abnormalities in the secretion of another hormone, called luteinizing hormone (LH), that are often seen in women with PCOS. However, another group had normal LH secretion. The girls with the abnormal LH secretion had higher levels of another hormone, called insulin, than the girls with normal LH secretion. The investigators will test whether metformin, an insulin-sensitizing agent, changes the effects of high male hormone levels in adolescent girls, specifically by looking at their LH secretion response following metformin treatment.

The objective of this study is to investigate the effects of two isocaloric maintenance diets with different meal timing distribution on insulin resistance hyperandrogenism and cytochrome P450c17 alpha activity in lean PCOS women. The investigators hypothesis is that in lean PCOS women a Breakfast Diet (BD) which consist in high calorie breakfast and reduced dinner, vs Dinner Diet (DD) which consist in high calorie dinner with reduced breakfast; the BD will improve glucose and insulin response to OGTT and would decrease the hyperandrogenism and cytochrome P450c17 alpha activity.

Polycystic ovary syndrome occurs in about 10% of women of childbearing age. His pathogenesis is not fully understood. More and more research concerns the role of chronic inflammation in these women as the cause of the disease. In vitro studies have shown a significant reduction in testosterone production by teak cells after ibuprofen. The goal of the project is to use a low dose of ibuprofen in women with PCOS to lower androgen levels.

To compare metformin with pioglitazone in improving menstrual irregularities and hyperandrogenism in women with PCOS so that an alternate and better treatment option will be available for hyperinsulinemia in pcos patients.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility which affects 12-21% of the population.Several studies performed evaluate the possible benefit of metformin alone or in combination with clomiphene (CC)as first-line treatment for infertility in women with PCOS have reported conflicting results. These conflicting results may be due to the presence or absence of insulin resistance(IR).Metformin decreases IR .However there is not a single randomized clinical trial with metformin in IR PCOS patients. Therefore, the aim of current study is to compare CC with coadministration of metformin and with CC with coadministration of placebo in IR PCOS patients to induce ovulation.

Treatment of obesity related to Polycystic Ovary Syndrome with topiramate or placebo to assess improvement of clinical and laboratory parameters after 6 months of follow-up

This is a Phase IV, randomized, double-blind, comparative study of the use of two preparations of ethinyl estradiol and cyproterone acetate in the treatment of menstrual irregularities of hyper-androgenic origin.

The purpose of this research is to explore the effects of chronic androgen exposure on sympathetic nervous system activity (SNSA) and baroreflex control of blood pressure responses in transgender men (trans men) taking gender affirming hormone therapy (HT). Blood pressure, baroreflex gain, and frequency of sympathetic responses to changes in blood pressure will be assessed in trans men and a control group of cisgender women. To fully understand HT effects on blood pressure regulation in trans men, it is crucial to understand how both SNSA, and the pattern of SNSA, can be influenced by high levels of androgen exposure in the female cardiovascular system, as well as how the two regulatory components may interact.
