Background and Aims: Various types of infertility are associated with uncontrolled hyperglycemia and diabetes. Development of oxidative stress is one the most important factors in the alteration of spermatogenesis in diabetic conditions. Consequently, the reduction of oxidative stress with antioxidant compounds can be effective in the reduction of tissue alterations. The aim of this study was to evaluate the efficacy of coenzyme Q10 in improvement of spermatogenesis in adult diabetic rats. Material and Methods: 32 adult rats were divided into four groups of control and treatment. Coenzyme Q10 (10 mg/kg body weight - b.w.) was administrated to one control and one diabetic (intraperitoneal injection of 45 mg/kg b.w. of Streptozotocin) groups. Blood concentrations of FSH, LH and Testosterone were measured. Histology of testicular tissue and sperm analysis were considered for evaluation of spermatogenesis. Results: Administration of Coenzyme Q10 led to increase of pituitary gonadotropins levels in diabetic rats. Testosterone levels were not changed significantly. Testicular morphology, spermatogenic indices and sperm analysis were improved in treated diabetic rats. Conclusions: The results of this study suggest that the use of Coenzyme Q10 has positive effects in reduction of spermatogenic alterations following induction of experimental diabetes in rats.
