20 hours of tube time hits 'down there'
TV doesn't just kill brain cells faster than dope. It also kills sperm so well that "Big Bang Theory" just might be the next great form of birth control.
In a new study of 189 men between the ages of 18 and 22, researchers found that men who spend 20 or more hours a week parked in front of the idiot box have 44 percent fewer sperm than men who watch the least.
So-called bad habits like drinking and smoking won't kill sperm, according to the study in the British Journal of Sports Medicine. (So much for calling them "bad" habits, huh?) Not even obesity and drug abuse can do the job.
Of course, I don't think sitcoms are actually responsible for all that damage on their own.
No, the real sperm killer here is what I refer to as "meat-in-the-seat syndrome," the sedentary couch-potato lifestyle that's also been shown to cause obesity, diabetes, heart disease, and a higher risk of a premature death.
In other studies, we've seen that even regular exercise can't undo the damage of too much sofa surfing, and that's true here, too: Regular exercise couldn't reverse all the damage caused by 20 or more hours in front of the TV.
So if you've got a serious TV habit of your own, it's clearly past time to change the channel. And while you're at it, change your underwear too. The study also finds that men who wear boxers have higher sperm counts than men who prefer tighty whiteys.
