Rosiglitazone, a PPAR-γ ligand was tested against the nicotinamide (230 mg/kg) and streptozotocin (65 mg/kg) induced reproductive defects in experimental type-2 diabetes mellitus. Rosiglitazone was tested in two doses (1 and 10 mg/kg, p.o daily for 4 weeks) to evaluate its role on the type-2 diabetes induced changes in the sperm shape and sperm count in rats, besides, estimating the serum antioxidant enzyme levels. The results indicate that administration of rosiglitazone produced a dose-dependent inhibition against the alterations induced by the diabetic condition. At 10 mg/kg, rosiglitazone significantly (P<0.001) prevented the abnormalities in sperm shape and increased the sperm count, while the lower dose increased (P<0.01) only the sperm count in the diabetic animals. The antioxidant study indicated that administration of rosiglitazone to diabetic animals improves the antioxidant status. These observations suggest that the antioxidant property of rosiglitazone might have contributed for its ability to decrease the type-2 diabetes mediated sperm abnormalities.
