Metformin and troglitazone in the treatment of female infertility associated with polycystic ovarian syndrome

Abstract

Polycystic ovarian syndrome is the most common cause of anovulatory infertility and causes menstrual disruption in 5-10% females, and is characterized by insulin resistance, hyperinsulinemia, hyperandrogenism and anovulation. Such factors are responsible for the increased miscarriage and infertility in women with PCOS. Administration of various insulin sensitizing drugs, such as metformin and troglitazone have been shown to decrease serum androgen concentrations and to increase ovulation rates, increase conception and decrease miscarriage in affected women.
