Polycystic Ovary Syndrome could be triggered in the womb, according to scientists who have reversed the little-understood condition in mice. Researchers in France believe PCOS could be caused by the fetus being overexposed to a hormone known as anti-Müllerian (AMH). PCOS affects as many as five million women of reproductive age in the U.S. Those with the condition have higher than normal levels of male hormones, which can trigger excess hair on the face and body. Other symptoms include multiple cysts on the ovaries, as well as irregular periods and difficulties becoming pregnant.
