| | Polycystic ovary syndrome |
 | | One of the most important characteristics of PCOS is hyperandrogenism, the excessive production of male hormones (androgens), particularly testosterone, by the ovaries. |
 | | Hyperandrogenism has been linked with insulin resistance (the inability of the body to respond to insulin) and hyperinsulinemia (high blood insulin levels), both of which are common in PCOS. |
 | | The interaction of hyperinsulinemia and hyperandrogenism is believed to play a role in chronic anovulation in susceptible women. |
