Get moving and improve sperm quality


More and more studies are showing a decreased quality of semen in young men. A recent study published in the British Journal of Sports Medicine posits a theory that an increase in sedentary lifestyle (video gaming and TV watching for instance) may be contributing to poor sperm quality.

Lazy lifestyle = lazy sperm?

The new study evaluates the relationship between sitting around and sperm count. “The objective of this study was to evaluate the relationships between semen quality and both physical activity and TV watching among young, healthy men. We hypothesized that increased physical activity was associated with higher sperm count, concentration and motility, and a lower proportion of morphologically abnormal sperm. Furthermore, we hypothesized that increased TV watching time was associated with decreased semen quality parameters,” wrote the authors of the study.

Almost 200 young men joined the study

The 189 men who participated in the study were asked to report the number of hours per week they spent exercising and watching TV. Semen samples were also analyzed. They were also asked to report other factors that are known to affect sperm quality: smoking, known reproductive issued, diet and stress levels. Exercise levels varied from 5 to 14 hours a week. Time in front of the tube ranged from 4 to 20 hours. Those who were more physically active also enjoyed a better, healthier diet than those men who were more sedentary.

Physical activity improves sperm count

The young men who had a sedentary lifestyle and watched over 20 hours of TV a week had nearly half the sperm (44% less) of men who don’t watch much TV. Men who exercised 15 hours a week had 73% higher sperm count than men who did little to no exercise. Frequency and level of difficulty made no difference.

Next: find out what types of exercise are most effective

“Future studies should also evaluate the extent to which different exercise types affect semen quality as previous studies suggest that there might be opposing effects of different types of activity on semen characteristics.”
