Exercise Boosts Semen Quality

by Berkeley Wellness  |  

Men who want to boost their sperm count and other markers of semen quality should get moving, suggests a large study from Iran in the journal Reproduction, which assigned healthy but relatively sedentary men, ages 25 to 40, to follow aerobic exercise protocols of varying time and intensity—or no exercise—for 24 weeks.

All exercise groups showed improvements in semen quality across all measures, including increased number and motility of sperm, compared to no exercise. But moderate-intensity exercise (25 to 30 minutes of walking or jogging on a treadmill, three to four times a week, increasing to 40 to 45 minutes, four to six times a week) was better than high-intensity exercise.

Exercise appears to decrease oxidative stress and inflammation, but some of the benefit was also attributed to weight loss and decreased body fat from the exercise. The study did not look at pregnancy outcomes, however.
