Scientists may be one step closer to understanding why polycystic ovary syndrome (PCOS) tends to run in families.
The new research, presented July 1 at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology in Paris, suggests that "disruptions" in the way genes are turned on and off may increase the likelihood of developing PCOS. These "epigenetic" changes alter gene activity without changing DNA's underlying code, but they may also be passed down through families.
