Polycystic ovary syndrome (PCOS) is a set of symptoms due to elevated androgens in females.[4][14] Signs and symptoms of PCOS include irregular or no menstrual periods, heavy periods, excess body and facial hair, acne, pelvic pain, difficulty getting pregnant, and patches of thick, darker, velvety skin.[3] Associated conditions include type 2 diabetes, obesity, obstructive sleep apnea, heart disease, mood disorders, and endometrial cancer.[4] It is sometimes referred to as polycystic ovary disease (PCOD) when there is ultrasonographic evidence of the presence of ovarian cysts.
