Approximately 5 million people suffer from PCOS. Polycystic Ovary Syndrome is a condition that causes cysts to develop on the ovaries due to the overproduction of androgens. This hormone can also lead to other symptoms such as obesity, hair loss, heart disease, diabetes, high blood pressure and endometrial cancer. PCOS can also cause a person to become extremely hairy (the condition for this is called hirsutism). It is likely that the bearded ladies of circus fame suffered from this condition. Because PCOS is more closely related to your body’s metabolic processes, it is possible for men to develop this condition.
