Who would have thought that men who exercise regularly have better quality semen than men who don’t?
Ben definitely has better quality breast milk though.
Truly a shocking development.
Healthy young men who exercise regularly may have better quality semen than their sedentary peers, a study of sperm donors suggests.
Even though being overweight and sedentary has long been tied to low sex drive and an increased risk of infertility, less is known about how physical activity levels might impact semen quality among men without fertility issues, the study team notes in Human Reproduction.
For the current analysis, researchers analyzed thousands of sperm samples from hundreds of men who qualified to donate sperm based on their health history and semen quality. Donors needed healthy levels of three things that can make conception more likely: sperm concentration, or the amount of sperm released when men ejaculate; sperm morphology, meaning the ideal size and shape with an oval head and a long tail; and motility, or the ability of sperm to move through the female reproductive tract to reach an egg.
Men who got the most total exercise and logged the most time doing intense workouts had better sperm motility than men who got the least amounts of exercise, the study found.
Some previous research also suggests that excessive exercise is associated with infertility, said Dr. Muhammad Imran Omar, a researcher at the University of Aberdeen in the UK who wasn’t involved in the study.
“Therefore, it is important that the exercise should be done in moderation,” Omar said by email.
Keep in mind that “excessive exercise” is often associated with anabolic steroid use, and anabolic steroids are associated with infertility.
Even though the study didn’t find sedentary time associated with lower quality sperm, sitting too much is associated with other health problems like diabetes, obesity and heart disease that can in turn make it harder for couples to conceive, said Dr. Joan Khoo of Changi General Hospital in Singapore.
People who want to conceive should still try to limit sedentary time, Khoo, who wasn’t involved in the study, said by email.
“If your job is mostly sedentary, take every opportunity to get out of the chair or vehicle; stand, walk or climb stairs whenever you can,” Khoo advised. “Park the car some distance away or get down one bus stop earlier, and exercise as much as possible when not at work.”
The bottom line here is: move your body and be active. You don’t need to go overboard with exercise and make it the center of your life, but exercise does need to be a part of your life.
Physical activity is something that will help you in every other aspect of your life — from developing discipline and learning to set and achieve goals to increasing your confidence and improving your health.
It can even help you think.
A recent study found that physically fit people have stronger and sharper brains.
If you’re too busy with work and you think that you don’t have the time to exercise, consider going for exercises that you can perform anywhere with little time, like push-ups and one-leg squats.
Even a tiny amount of exercise is significantly better than not doing any exercise at all.
