Too much TV linked to lower sperm count

Young adult males never worry about their fertility, because they are still at the age that they are more worried about the size of their reproductive organ and performance issues, however young men should start thinking about their sperm count as a recent study has suggested that even watching too much TV can affect the number of swimmers in a man’s semen.

The research carried out by the Harvard School of Public Health involved 189 healthy male students between the ages of 18 to 22, enrolled at the University of Rochester in N.Y. in 2009 and 2010 and found that couch potatoes who watched TV for 20 or more hours a week had lower sperm counts, a whopping 44% lower, according to the study that was published in the British Journal of Sports Medicine.

Instead those who exercised 15 or more hours every week revealed sperm counts 73% higher than those who exercised for less than five hours a week.

The study group was asked about exercise, the number of hours they spent in front of the TV, diets, their stress levels and whether they smoked, as previous studies have found that a diet rich in fats and smoking can impact on sperm count.

Senior researcher and author of the study Dr. Jorge Chavarro, said: "Adopting a less sedentary lifestyle may have a positive impact on sperm counts and we know from other studies that sperm counts are related to fertility - higher sperm counts are related to higher fertility. Men with low sperm counts can still father children although they may have difficulties doing so."

Dr Allan Pacey, a senior lecturer in Andrology at the University of Sheffield, believes that sitting on couch for hours on end could increase testicular heating and decrease sperm counts, but warned that even to much exercise isn’t always beneficial:

"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, which might account for the findings. This should be a relatively easy study to perform but, before all worried men hunt for their sports bags, it's important to note that other research suggests that doing too much exercise can be harmful to sperm production, and this study did not examine the type and intensity of exercise their participants were undertaking."
