The present study investigated the effects of Kolaviron (KV) on the testicular and epididymal tissue antioxidant status in streptozotocin (STZ)-induced diabetic rats. Diabetes was induced by a single intraperitoneal injection of STZ at 50 mg/kg body weight. The antioxidant status was studied by evaluating epididymal and testicular levels of malondialdehyde (MDA), a lipid peroxidation (LPO) marker, and the activities of catalase (CAT) glutathione peroxidase (GPX) and superoxide dismutase (SOD) were also assessed using biochemical techniques. Diabetes induction resulted in testicular and epididymal LPO and adversely affected the activities of antioxidant enzymes evident by a noticeable decrease in enzyme activity in both tissues. The potential antioxidative effects of KV in the testicular and epididymal tissues of STZ-induced diabetes were revealed by its ability to mitigate against LPO and increase the activity of antioxidant defense enzymes in the reproductive tissues studied. KV might potentially be used as an antioxidant as well as antidiabetic treatment; however, further studies are needed.
