Young healthy men who spend more than 20 hours a week watching television are more likely to have problems with sperm count and quality.

At the same time, men who play sports for more than 15 hours a week have sperm counts 73% better than their inactive peers who exercise less than 5 hours a week..

Such interesting results were published by the popular British publication British Journal of Sports Medicine..

Dr. Alan Pacey, a professor of andrology at the University of Sheffield and chairman of the British Fertility Society (BFS), says the results of the study are consistent with current medical beliefs about male fertility..

“We know that men who wear tight underwear have problems with sperm quality. The same principle applies for prolonged sitting on the couch in front of the TV.. This contributes to prolonged overheating of the testicles and deterioration of spermatogenesis, ”says the professor.

For unknown reasons, scientists have seen deterioration in sperm quality in Western countries over the past few decades.. The authors of the study believe that a sedentary lifestyle plays an important role in this..

They analyzed the sperm quality of 189 American men from New York State (participants were 18-22 years old). The frequency and intensity of physical training for the previous few months was found out from all participants. They also learned the daily norm of sitting in front of the screen for the same period..

Researchers took into account other factors that can affect sperm quality, including reproductive and general diseases, diet, stress levels, smoking, and alcohol consumption..

Physically active men were more likely to follow a healthy diet than those who led a sedentary lifestyle and spent a lot of time in front of the screen..

Analysis showed that physically active men (more than 15 hours of training per week) had sperm counts 73% better than their inactive peers.

When we analyzed the nature of the load, it turned out that light physical activity did not affect the quality of sperm in any way, no matter how many men were engaged.

Sitting in front of the television had the opposite effect.. Men who spent more than 20 hours a week in front of the screen had sperm counts 44% worse than men who did not watch TV at all.

The analysis showed that the time spent in front of the screen crossed out the positive effects of exercise in active men, making their results average.

The authors warn that the deterioration of semen in sedentary men did not necessarily deprive them of their ability to conceive a child.. But the chances of fatherhood declined.

Now researchers want to find out which exercises best influence sperm quality.. These data will help andrologists recommend optimal exercise routines for men with fertility problems..
