Men who watch TV for 20 hours or more per week have almost half the sperm count of men who watch TV for 4 hours or less, and watching TV can eliminate the benefits of exercise.
According to the Daily Mail of England, a new study from Harvard University has found that if young men watch three hours of television a day, their sperm count decreases by nearly half compared to men who watch less television, which means their fertility is also reduced by half.
Sitting and watching TV can halve fertility
The rumor that Coke kills sperm has been widely circulated. Scientists have recently warned young men that if they constantly watch TV and lack physical activity, their sperm count will also drop significantly. Researchers at Harvard University in the United States have found that men who watch only three hours of television a day have half the sperm count of those who watch less television.
In the study, scientists analyzed 189 men aged 18 to 22. More than half of them are of normal weight and have a lower probability of infertility. The researchers assessed the quality of their sperm and recorded the time they spent exercising and watching TV over a period of three months. After integrating factors that may affect sperm quality such as diet, stress, and smoking, it was found that they spent 5-14 hours per week exercising moderate to intense intensity, while watching TV ranged from 4-20 hours per week.
Data analysis shows that men who watch TV for 20 hours or more per week have almost half the sperm count as men who watch TV for 4 hours or less, and watching TV can eliminate the benefits of exercise.
Harvard researchers have pointed out that sedentary men have significantly lower sperm counts than men who regularly engage in moderate intensity exercise, which may be due to lack of exercise or excessive testicular temperature caused by prolonged sitting posture. In addition, experts also remind men planning to have children to avoid wearing tight underwear to improve sperm quality, and point out that men who often drive and ride bicycles also have a risk of infertility.
This is the first time that scientists have directly studied the relationship between sperm quality and physical activity levels. Through research conducted by the Harvard School of Public Health, it has been concluded that healthy men who watch more than 20 hours of TV per week have an average 44% fewer sperm counts than men who do not watch TV; At the same time, men who engage in moderate to vigorous exercise for 15 hours or more per week will have 73% more sperm than those who exercise less than 5 hours per week.
