Polycystic ovary syndrome (PCOS) is a hormonal disorder that prevents the eggs in the ovaries from maturing properly, often creating numerous fluid-filled sacs known as ovarian follicles. This often causes irregular menstrual cycles and infertility.
PCOS is characterized by excess levels of androgens (the hormone testosterone) and higher than average insulin levels. Though androgens naturally occur in women, women with PCOS have higher levels of androgens than those typically found in females. Elevated levels of testosterone contribute to the changes seen in how the ovaries function.
There is no cure for PCOS, but medical treatments and lifestyle changes can reduce testosterone levels and help patients effectively manage symptoms.
