Too Much TV Time Can Sabotage Your Sperm Count

Medically reviewed in January 2022

Men: Put down the remote and step away from the couch. All that time you spend watching TV (you know who you are) could seriously slash your sperm count.

A Harvard School of Public Health study published in the British Journal of Sports Medicine found that healthy men who spent 20 or more hours a week glued to the tube had a 44% lower sperm count than those who watched less TV. But it’s not all bad news. Researchers also found that men turbocharged their sperm production by as much as 73% if they did 15 hours a week of moderate to vigorous exercise.

Why TV Hurts, Exercise Helps
Researchers say the decrease in sperm count could be associated with leading a sedentary lifestyle, which is a risk factor for obesity and other diseases. Being overweight may alter hormone levels and heat up your testicles, causing you to produce less sperm. (Love TV? Do this during commercials.) Exercise, on the other hand, has been shown to boost testosterone levels and improve insulin function, both factors related to higher sperm concentration.
