The present study is designed to demonstrate the effect of Ginkgo biloba and Olive oil on the reproductive performance of male rats exposed to oxidative stress induced by Potassium dichromate with respect to male sex hormones, semen parameters and testicular antioxidant system,. Forty Wister albino rats were distributed into four groups and each group have ten rats, control group, Potassium dichromate group (Potassium dichromate 24 mg/kg administered with gavage for 2 month), Potassium dichromate treated with Ginkgo biloba group (Potassium dichromate and Ginkgo biloba 40 mg/kg administered at half an hour interval for 2 months) and Potassium dichromate treated with olive oil group (Potassium dichromate and Olive oil 1 ml/kg administered at half an hour interval for 2 months). The statistical analysis of results showed a significant (P<0.05) decrease in sperms count, the percentage of sperms viability, the level of sex hormones, ceruloplasmin, glutathione concentration, and superoxide dismutase activity, antioxidant activity (AOA), germinal epithelium height and diameter of seminiferous tubules and a significant increase of sperm percentage abnormalities, dead sperm, malondialdelyde (MDA), peroxynitrite (ONOO-) in Potassium dichromate group, compared with control group. The administration of Potassium dichromate with Ginkgo biloba and Olive oil separately result in a significant increase of sperms count, sperms viability, sex hormones levels, ceruloplasmin, glutathione concentration , superoxide dismutase and antioxidant activity, germinal epithelium height and diameter of seminiferous tubules and a significant decrease of sperm abnormalities, dead sperm percentage, MDA, ONOO-. In conclusion the levels of antioxidant parameters, sperm count and sperm viability were restored to normal values when Potassium dichromate administered in combination with Ginkgo biloba or with Olive oil therefor Ginkgo biloba and Olive oil may be beneficial for improving reproductive performance of male rats.
