Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders that affects approximately 10% of women in reproductive age and occurs among all races and nationalities . So far pathogenesis of polycystic ovary syndrome is unknown.The principal features are lack of regular ovulation, which lead to infertility, and hyperandrogenism. The symptoms and severity of the syndrome vary greatly among women. In some women insulin resistance, diabetes type 2 and obesity coexist with PCOS [2,3]. The first definition was formed by Stein and Leventhal. During years the definition of polycystic ovary syndrome had been changing. Unfortunatelly, even these days, having much better diagnostic tools, we have doubts if definition is proper.
