Abstract

Objective
The strong antioxidant activity of Commiphora mukul prompted us to conduct the present study to explore whether treatment with C. mukul extract (CME) would have any protective influence on sperm parameters, testosterone levels, and plasma glucose levels in streptozotocin (STZ)-induced diabetic rats.
Methods
Male Wistar rats were randomly divided into four groups: control, control animals treated with CME, diabetic animals, and diabetic animals treated with CME. CME extract (300 mg/kg) was administered for 60 days by daily gavage. Diabetes was induced by an intraperitoneal injection of 50 mg/kg STZ. The epididymal sperm count, weight, motility, morphology, viability, and serum testosterone and glucose levels were determined.
Results
In the diabetic animals, CME decreased blood glucose levels (p<0.05), increased the total sperm count (p<0.05), and decreased the proportion of sperm with abnormal morphology (p<0.05). Diabetes reduced sperm motility (p<0.001), and CME supplementation partially reversed this effect of diabetes (p=0.003). Furthermore, in diabetic animals, CME decreased the proportion of immotile sperm (p<0.001). In rats, diabetes caused a significant decrease (p<0.05) in serum testosterone levels (F[3, 28]=3.283, p=0.035), but treatment of diabetic animals with CME increased serum testosterone levels.
Conclusion
The present study demonstrated that C. mukul possesses proandrogenic activity and exerts a beneficial effect on sperm parameters in diabetic rats.
