What Increases Your Risk

The main risk factor for polycystic ovary syndrome (PCOS) is a family history of PCOS. Experts think that a combination of genes plays a part in PCOS.³ If you have the syndrome, your sisters and daughters have a 50% chance of developing PCOS.¹

A family history of diabetes may increase your risk for PCOS because of the strong relationship between diabetes and PCOS. Research on this risk factor is ongoing.

The use of the seizure medicine valproate (such as Depakote) has been linked to an increased risk of PCOS.¹
