Polycystic ovary syndrome (PCOS) is a condition that affects a woman’s hormone levels.

Women with PCOS produce higher-than-normal amounts of male hormones. This hormone imbalance causes them to skip menstrual periods and makes it harder for them to get pregnant.

PCOS also causes hair growth on the face and body, and baldness. And it can contribute to long-term health problems like diabetes and heart disease.

Birth control pills and other medicines can help regulate the menstrual cycle and treat PCOS symptoms like hair growth and acne.
