In this study, we want to find out more about polycystic ovary syndrome(PCOS). This is a common problem in about 7% of teenage girls. Problems may include irregular periods, extra hair on the face, chest and back areas. It seems that PCOS is related to a high level of male hormones and to another problem called metabolic syndrome(MBS). People with MBS may have high blood pressure, low good cholesterol, high blood fats and extra fat around the waist. Girls with MBS are at high risk for getting diabetes and heart disease.
