IS TV KILLING SPERM?
Sitting in front of the box has been blamed for another ailment. It seems men who watch more than 20 hours of TV a week have almost half the sperm count of those who watch hardly any, researchers from Harvard University have found.
However, if some exercise is thrown into the mix, the sperm counts appear to improve. Men taking part in the research who clocked up 15 or more hours of moderate to vigorous exercise every week were found to have sperm counts that were 73 per cent higher than the least physically active study participants.
The study also found those who watched the most TV (more than 20 hours a week) had a 44 per cent lower sperm count than those who watched the least. Time spent in front of the box, however, had no impact on sperm motility, shape or volume.
Interestingly, men who did regular exercise but also watched a lot of TV recorded lower sperm counts than those who avoid spending hours with the remote in hand.
This research adds fuel to fears that sperm counts and quality worldwide are deteriorating. A French study of 26,000 men, conducted between 1989 and 2005, found that average sperm counts fell by a third from Provence to Paris and everywhere in between.
