Hyperinsulinemia contributes to the pathogenesis of ovarian dysfunction in insulin-resistant states, including polycystic ovary syndrome (PCOS). Peroxisome proliferator activated receptor-gamma (PPAR-gamma) agonists [thiazolidinediones (TZDs)] ameliorate hyperandrogenism in polycystic ovary syndrome presumably because they reduce systemic hyperinsulinemia. Direct effects of TZDs in the ovary, however, cannot be excluded. We explored direct effects of TZDs in cultured human ovarian cells.
