Polycystic ovary syndrome (PCOS) represents a group of symptoms that result from hormone abnormalities.

In PCOS it is thought that many small cysts develop on the ovaries causing the menstrual problems that most people with PCOS experience.

The cause of PCOS is unknown, but we know that it runs in families. If your mother or sister has PCOS, it is more likely that you will also.

It is very important for those affected to understand the syndrome and get treatment because PCOS may increase the risk of developing uterine cancer, diabetes and heart disease.
