Polycystic ovary syndrome (PCOS)
Polycystic ovary syndrome (PCOS) is a problem with hormones that affects women during their childbearing years (ages 15 to 44). Between 2.2 and 26.7 percent of women in this age group have PCOS
Many women have PCOS but don’t know it. In one study, up to 70 percent of women with PCOS hadn’t been diagnosed.
PCOS affects a woman’s ovaries, the reproductive organs that produce estrogen and progesterone — hormones that regulate the menstrual cycle. The ovaries also produce a small amount of male hormones called androgens.
