How does polycystic ovary syndrome affect my menstrual cycles?

Polycystic ovary syndrome (PCOS) greatly affects your menstrual cycles. During your menstrual cycle your ovaries produce estrogen, progesterone, and androgens to prepare for pregnancy. If your egg is not fertilized during that time the body gets rid of the uterus lining during menstruation. If you have PCOS, however, your ovaries produce too much androgen, causing problems like an irregular period and ovulation, surplus body hair, acne, and fertility.
