Overview
PCOS is the most common form of chronic anovulation associated with androgen excess. Polycystic ovary syndrome occurs in approximately 5% to 10% of reproductive-age women. The diagnosis of PCOS is made by excluding other hyper androgenic disorders like nonclassic adrenal hyperplasia, androgen-secreting tumors, hyperprolactinemia in women with chronic anovulation and androgen excess. During the reproductive years, PCOS is associated with important reproductive morbidity, including infertility, irregular uterine bleeding, and increased pregnancy loss. The endometrium of the patient with PCOS must be evaluated by biopsy because long-term unopposed estrogen stimulation leaves these patients at increased risk for endometrial cancer. PCOS is also associated with increased metabolic and cardiovascular risk factors. These risks are linked to insulin resistance and are compounded by the common occurrence of obesity, although insulin resistance also occurs in nonobese women with PCOS. PCOS is considered to be a heterogeneous disorder with multifactorial causes. PCOS risk is significantly increased with a positive family history of chronic anovulation and androgen excess, and this complex disorder may be inherited in a polygenic fashion
