Exercise Training Attenuates Detrimental Effects of Diabetes Mellitus on Reproductive Parameters

Diabetes mellitus affect male reproductive function at multiple levels including control of spermatogenesis. The aim of this research was assessing the effect of aerobic training on reproductive parameters in diabetic male rats. Thirty male Wistar rats (age: 2-3 mount, weight: 200-250 gr) randomly divided in to three groups: healthy control, diabetic control and diabetic trained (n=10 each). A single intraperitoneal injection of streptozotocin at a dose of 55 mg/kg was used for induction of diabetes. One week after streptozotocin injection, the endurance training protocol was performed for eight weeks (five bouts per week of treadmill running each 20-60min with 27 m/min) and forty-eight hours after the last training session, left epididymis of the rats was examined for studying sperm parameters and blood serum samples were examined for evaluating reproductive hormones. Data were analyzed using one-way ANOVA and turkey’s post hoc test at 0.05%. All of the sperm parameters (count, motility, morphology and viability) significantly were lower in diabetic rat when compared with healthy control group (P
