PCO: Polycytic Ovaries
Polycystic ovarian syndrome, or PCOS, is a condition in which a woman’s levels of the sex hormones estrogen and progesterone are out of balance. This leads to the growth of ovarian cysts (benign masses on the ovaries). PCOS can cause problems with a women’s menstrual cycle, fertility, cardiac function, and appearance.
What causes PCOS?
While the exact cause of PCOS is unknown, doctors believe that hormonal imbalances and genetics play a role. Women are more likely to develop PCOS if their mother or sister also has the condition.
Overproduction of the hormone androgen may be another contributing factor. Androgen is a male sex hormone that women’s bodies also produce. Women with PCOS often produce higher-than-normal levels of androgen. This can affect the development and release of eggs during ovulation. Excess insulin (a hormone that helps convert sugars and starches into energy) may cause high androgen levels.
