Serum glucose levels (mg/dl) in normal rats (n = 5), PCO induced rats (n = 5) and treated rats with metformin and pioglitazone (n = 5). Serum glucose was elevated in PCO rats compared with control animals. Treatment of PCO rats with metformin and pioglitazone resulted in reduction of glucose level in relation to PCO untreated rats. Data were presented as the mean ± SD. Different letters denote differences among groups at P < 0.05.
