How does polycystic ovary syndrome (PCOS) affect a woman while pregnant?
There appears to be higher rates of miscarriage, gestational diabetes, pregnancy-induced high blood pressure (pre-eclampsia), and premature delivery in women with PCOS. Researchers are studying how the diabetes medicine metformin can prevent or reduce the chances of having these problems while pregnant. Metformin also lowers male hormone levels and limits weight gain in women who are obese when they get pregnant.
