Polycystic ovary syndrome (PCOS) is the most common cause of infertility in reproductive-age women and an important harbinger of metabolic disorders such as diabetes and heart disease.
It affects an estimated 5 to 10 percent of females and is associated with an increased risk of diabetes and obesity, and as a result, an increased risk of cardiovascular disease.
The syndrome is generally characterized by the presence of polycystic ovaries, hyperandrogenism (the condition caused by excess male hormones or male-like traits) and irregular ovulation and menstruation.
Polycystic ovary syndrome has hereditary qualities, but a definite gene or distinct genetic cause has not yet been found.
