Although the cause of Polycystic Ovary Syndrome (PCOS) is not known, it appears that PCOS may be related to many different factors working together. These factors include insulin resistance, increased levels of hormones called androgens and an irregular menstrual cycle.
PCOS affects all areas of the body, not just the reproductive system. It increases a woman’s risk of serious conditions that may have lifelong consequences. These include type 2 diabetes, heart disease, metabolic syndrome, endometrial hyperplasia and endometrial cancer.
