Exaggerated gonadotrophin releasing hormone (GnRH) pulsatility . The pathophysiology of the polycystic ovary. [ 8] 1) An alteration in gonadotropin-releasing hormone secretion results in increased luteinizing hormone (LH) secretion. 2) An alteration in insulin secretion and insulin action results in.. Polycystic ovary syndrome (PCOS) was hypothesized to result from functional ovarian hyperandrogenism (FOH) due to dysregulation of androgen secretion in 1989-1995. Subsequent studies have supported and amplified this hypothesis
Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age. Women with PCOS may have infrequent or prolonged menstrual periods or excess male hormone (androgen) levels. The ovaries may develop numerous small collections of fluid (follicles) and fail to regularly release eggs.
