Term Cardio Exercise Analysis
A couple of recent studies have pointed to one fact: moderate cardio exercise can significantly improve male fertility.
The widespread notion that working out lowers a man's sperm count is wrong. This is according to two studies, one published in the British Journal of Sports Medicine and the other in the journal Reproduction.
What Do the Studies Show?
The first study was conducted at the Harvard school of Public health. The subjects were 189 men with sedentary lifestyles. The study found that men who spent more than 14 hours each week exercising had a 73 percent greater sperm concentration when compared men who exercised for only 14 hours a week. The effect of the exercise was consistent even when researchers accounted for other factors …show more content…
These men performed at least 15 hours of physical activity a week. Researchers defined the type of activity that these men did as ranging from moderate to vigorous. When compared to men who were sedentary for more than 20 hours per week, they had a 44 percent higher sperm concentration.
The results from the Urmia University study also pointed to the benefits of moderate exercise. The MICT group saw their semen volume increase by more than eight percent. They also had a 12 percent higher motility and a 17 percent improvement in morphology. In addition, this group averaged a 22 percent increase in sperm count compared to the control group. A week after they stopped exercising, their sperm count and morphology returned to normal; the motility also returned to previous levels after a month.
The Urmia University researchers concluded that moderate exercise is an effective way for sedentary men to improve the count and quality of their sperm. The research did not look into why moderate exercise had the most pronounced effect on sperm quality.The hypothesis is that the testes were subject to less stress and inflammation than with more strenuous
