Polycystic ovary syndrome (PCOS) is the most common cause of ovulatory disorders and female infertility. Signs and symptoms of PCOS may include anovulation or menstrual irregularities, ovarian cysts on ultrasound, hyperandrogenism including hirsutism, acne, and alopecia, insulin resistance. Insulin resistance and secondary hyperinsulinemia appear to play a causative role in the development of PCOS. In addition, PCOS patients suffer from elevated oxidative stress and systemic inflammation.
