Abstract
Physical activities improve the fertilization potential by boosting semen quality versus sedentary individuals. However, the effect of exercise training on semen quality, changes based on its intensity.
The current experimental trial was investigated the effect of different exercise training protocols (ETPs) on sperm count and motility, as main parameters influencing male fertilization potential.
Twenty four mature male Wistar rats (200 ± 20 g) were randomly assigned into four groups, including sedentary (control), Low (LICT, 20-39% Smax), Moderate (MICT, 40-60% Smax) and High (HICT, 61-84% Smax) intensity continuous ETPs by considering a treadmill running [60 minutes/day (5 times/week)], for 8 weeks. Twenty four hours following the last training, sperms from the left epididymis were considered for count and motility analyses. Moreover, the relative ratio of sperm motility/count was assessed. Then, the Data were analyzed by One-way ANOVA conducting the post-hoc Bonferroni test.
MICT and HICT ETPs significantly (p<0.05) decreased while LICT did not affect sperm count when compared with control animals. Although the sperm motility was decreased in the HICT group, no statistically significant difference was revealed between ETP-induced and control groups. However, the Motility/count ratio was increased in all ETP-induced animals.
Based on these findings, LICT, at least in the current experiment, does not affect both count and motility. In contrast, HICT and MICT negatively impact sperm count. Moreover, HICT with lower and MICT with higher impacts are able to maintain the sperm motility relative to preserved sperm volume. Taking together, minding considerable reduction in sperm count, it could be suggested that mainly HICT can negatively affect male fertilization potential by reducing sperm production.
