Want more sperm - stop watching TV and start exercising.

You might not be aware that sperm counts are dropping throughout the western world. It is thought our slothful lifestyle could be the issue. A very interesting article just published indicates this:

Sperm concentration and total sperm count were found to be directly related to physical 
activity in an analysis of 189 young American men (18-22 years). The sperm concentration in men 
who participated in moderate to vigorous activity ≥15 hours per week was 73% higher than in less 
active men who participated in moderate to vigorous activity <5 hours="" nbsp="" per="" span="" week.="">Men who watched >20 hours of TV per week had a 44% lower sperm concentration than men who watched no TV. 

So watching TV kills your sperm. I can't help but wonder if it is also all that negative stuff on TV affecting the most sensitive parts of your body. But more likely the heating effect of siting cooks them.
