OK guys if this headline doesn’t grab you, I am not sure what will. Here’s the latest data on why shedding the couch potato lifestyle and increasing your miles in your running shoes or on the bike can add vigor to your sperm.

A recent study published in the British Journal of Sports Medicine reiterated what we already know: semen quality in men appears to have declined over the past several decades. What the authors set out to correlate was the relationship between physical activity and television watching with sperm parameters in young, healthy men. Although I would have liked to see the study incorporate men of all ages between 18-90, we’ll start with young men.

The researchers compared the number of television hours watched per week to the number of hours of moderate and vigorous exercise performed per week. Semen quality was assessed by sperm concentration; motility, morphology and total sperm count.

The quality and quantity of sperm was directly related to the amount of physical activity performed. Men who performed the greatest amount of physical activity demonstrated a 73% higher sperm concentration then those who performed the least amount of activity. Inversely, men who watched the greatest amount of television produced a 44% lower sperm concentration.

The authors concluded that higher moderate-to-vigorous physical activity and less TV watching were significantly associated with higher total sperm count and sperm concentration.

Well guys…what are you going to do about that?
