Harvard: Exercise May Boost Sperm Quality

Men who exercise regularly appear to have higher quality semen compared with men who don’t exercise regularly, according to new research led by Harvard T.H. Chan School of Public Health researchers and colleagues.

The study examined data collected from 746 sperm donors at the Hubei Province Human Sperm Bank in China and found that men who had exercised more frequently and intensely had better sperm motility than men who got the least amounts of exercise.

“Regular exercise may improve semen quality parameters among healthy, non-infertile men, but it’s hard to tell how much exercise, and how often and what type of workouts men should do for optimal fertility,” said Harvard T.H. Chan School of Public Health’s Dr. Yi-Xin Wang in a December 31, 2019 Reuters article.

Other Harvard Chan School researchers who contributed to the study included Drs. Carmen MesserlianMariel Arvizu, and Jorge Chavarro.
