Ovarian Response to Recombinant Follicle Stimulating Hormone in Women With PCOS
Polycystic Ovary SyndromeHealthy2 moreWomen 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.
Effect of Metformin on Sensitivity of the GnRH Pulse Generator to Suppression by Estradiol and Progesterone...
Polycystic Ovary SyndromeHyperandrogenismMany, 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.
Meal Timing on Glucose and Hyperandrogenism in PCOS Women
Polycystic Ovary Syndrome (PCOS) WomenThe 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.

Menstrual IrregularitiesHyperandrogenismTo 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.
The Effect of Ibuprofen on Women With PCOS.
PCOSHyperandrogenism1 morePolycystic 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.
Metformine and CC Compared With Placebo and CC for Induction Ovulation in PCOS Patients With Insulin...
Polycystic Ovary SyndromeHyperandrogenismPolycystic 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.

Mechanisms of Blood Pressure Dysfunction in Transmen Receiving Testosterone
Transgender MenBlood Pressure1 moreThe 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.
