Grape seed extraction has many beneficial effects on the cardiovascular system and blood pressure and has also been proven to have anti-obesity effects and/or improve fatty acid oxidation and insulin responses. The objective of this study is to evaluate the effectiveness of grape seed extract on some physiological parameters in multiple systems. To this end, male mice were injected intraperitoneally with (100 mg/kg B.W) for 7 days. Serum was collected to detect the concentration of ALT and TSB (liver functions). Urea and creatinine (a kidney function) concentration was measured. Testosterone, LH, and FSH (male reproductive function) concentration were evaluated. Our results revealed a significant reduction in ALT concentration in the grape seed extraction group compared with the control group. Total serum bilirubin was non-detectable in both the grape seed extraction group as well as the control group. Urea and creatinine concentrations appeared to have no significant change between both grape seed extraction and the control group. Testosterone, LH, and FSH hormone levels were significantly raised in the grape seed extraction group compared with the control group. Prolactin hormone results revealed no change in both the grape seed extraction group and the control group. Our study showed up that grape seed extract can improve male reproductive hormones without any toxic effect on the liver or kidney.
