A study has revealed that men who do little exercise and spend much of their time watching television have lower spérm counts than more active men. The study, published in the British Journal of Sports Medicine, shows falling sperm quality is linked to lower levels of physical activity.
The study found that young men who watch television for just three hours a day have half the spérm count of men rarely found in front of the box. Yet 15 hours or more of exercise a week boosts sémen quality, according to the results in nearly 200 college students.
Also, experts say this could be due to lack of exercise, or to overheating of the tésticles caused by prolonged sitting. And some experts say men wanting to father children need to be selective about the sport they do, as well as avoid wearing tight underpants as these may harm spérm.
However, in the latest study from the Harvard School of Public Health (HSPH), healthy young men who watched more than 20 hours of television each week had a 44 per cent lower spérm count than those who almost did not watch. Men who exercised for 15 or more hours weekly at a moderate to vigorous rate had a 73 per cent higher spérm count than those who exercised less than five hours per week. Mild exercise did not affect sperm quality.
