What is polycystic ovary syndrome?
Polycystic ovary syndrome (PCOS) is a condition that occurs when an imbalance of hormone levels in a woman's body causes cysts (say: "sists") to form in the ovaries. The cysts are like tiny, fluid-filled balloons.
PCOS can cause changes in a woman’s menstrual cycles, fertility, hormone levels, heart and blood vessels, and appearance.
Women can develop PCOS during their teenage or childbearing years.
