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.="">5>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.
