resveratrol attenuates malathion induced damage in some reproductive parameters by decreasing oxidative stress and lipid peroxidation in male rats

Objective: malathion is the most organophosphates which capable to produce free radicals and induce disturbance on some of male reproductive parameter. resveratrol is an herbal polyphenol and it has been beneficial antioxidant effects during shortterm administration. this study was designed to evaluate the effects of resveratrol against damage induced by malathion to the reproductive parameter of male rats.materials and methods: in this experimental study, 48 male rats were randomly assigned to 8 groups: normal control (saline) and malathion control (250 mg/kg) groups; resveratrol groups (2, 8, 20 mg/kg) and malathion + resveratrol (2, 8, 20 mg/kg). treatments were administered intraperitoneally and gavage daily for 65 days. the sperm parameters, testis malondialdehyde (mda), total antioxidant capacity (tac), testosterone level and germinal layer height were evaluated and statistically analyzed.results: the results displayed that the values of all parameters except mda level (which increased) reduced significantly in the malathion control group compared to the normal control group (p < 0.001). the resveratrol and resveratrol + malathion treatments at all doses increased significantly all parameters except mda level (which decreased) compared to the malathion control group (p < 0.001). no significant modifications were observed in all resveratrol groups compared to the normal control group (p > 0.05).conclusion: resveratrol attenuates toxic effect of malathion on some of male reproductive parameters.
