BOSTON (CBS) – Harvard researchers have found yet another reason to get off the couch and exercise.

According to a new study led by Harvard School of Public Health researchers, the amount of physical activity men do affects sperm count.

The study, which looked at the habits of 189 college-aged men is published in the British Journal of Sports Medicine.

Results showed that men who watched more than 20 hours of television weekly had a 44-percent lower sperm count than those who watched almost no TV.

Men who exercised for 15 or more hours a week at a moderate to vigorous rate had a 73% higher sperm count than those who exercised less than five hours a week.

Researchers also found even in men with low sperm count, small amounts of exercise did not affect sperm quality.

Dr. Jorge Chavarro, of the Harvard School of Public Health says the study is another wake up call for the sedentary.

“I think the message is pretty clear,” Chavarro said. “Turn off your TV and get out and exercise.”
