Young men who watch more than 20 hours of television per week may have a harder time reproducing than men who watch less and exercise, according to a report published in the British Journal of Sports Medicine (February 4).
The study, conducted at the University of Rochester, surveyed 189 men (aged 18-22), asking them questions about their exercise, diet and TV habits. The men were also asked for a sperm sample.
The men who watched over 20 hours of television a week had a sperm count nearly 44% lower than those who watched less; and the men who exercised 15 or more hours weekly had a 73% higher sperm count than those who exercised less than 5 hours weekly.
"I would agree that there is evidence to suggest that moderate exercise could change men's physiology sufficiently to improve testicular health," Dr. Allan Pacey, who was not involved in the study, told the CBC.
"However, it remains to be seen if coaxing a TV watching couch potato into doing some regular exercise could actually improve his sperm count. Or whether there exists an unknown fundamental difference between men who like exercise and those who do not," he added.
