Abstract
Polycystic Ovary Syndrome is the most frequent cause of anovulatory infertility and Hyperandrogenism in young women. The mechanism(s) leading to anovulation is (are) still poorly understood.
The syndrome can be diagnosed after the exclusion of other medical conditions that cause irregular menstrual cycles and androgen excess and the determination that at least two of the following are present:
• Oligoovulation or anovulation (usually manifested as oligomenorrhea (fewer than nine menses per year) or amenorrhea).
• Elevated levels of circulating androgens (hyperandrogenemia) or clinical manifestations of androgen excess (Hyperandrogenism)include hirsutism, acne, and male-pattern hair loss (androgenic alopecia).
• Polycystic ovaries as defined by ultrasonography.
