Polycystic ovary syndrome (PCOS), also known as Stein-Leventhal syndrome or polyfollicular ovarian disease, is an endocrine disease that affects 5–10% of females of reproductive age. Women with PCOS generally show a minimum of two out of three conditions, which are absence of ovulation, causing no periods or irregular menstrual periods; signs of high androgens or high levels of androgens; and/or cysts on a single or both of the ovaries.
