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.
