Watching too much TV lowers sperm count

Clocking up to 20 hours a week watching television can do damage to a man's sperm count, according to new research from Harvard University.  But 20 hours seems like a lot, doesn't it?  But take a minute to think about it – two hours a night, four days a week, plus several hours a day of sports on the weekends…

The research found that men who have a more sedentary lifestyle had lower sperm counts than men who led active lifestyles.  According to the study, men who engaged in 15 hours of moderate to vigorous exercise a week had sperm counts, on average, that were 73 percent higher than average, while those who spent a lot of time in front of screens had sperm counts 44 percent lower than average.

This study did not necessarily differentiate overweight men from average weight men either; it looked at lifestyle alone. In addition to those leading a sedentary lifestyle, the researchers also expressed concern about men who spend significant time riding a bike or doing long distance running in tight clothing as factors that could counteract the positive benefits of exercise when it comes to sperm counts.

Even the men with the lowest sperm counts, however,  were not considered to be sub-fertile.
