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. 

The conditions generally associated with PCOS include cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, insulin resistance, metabolic syndrome, obesity, mood disorders, endometrial hyperplasia, and inflammation. Though the exact cause of PCOS is unknown, researchers believe that genetic and environmental factors are contributing influences.
