For many men, a lower sperm count can contribute to infertility. When you are trying to get pregnant, however, it’s important to increase the sperm count to its highest potential.

A couple of years ago, an interesting study showed that when it comes to male fertility, there is much to be said for taking action — as in getting up off the couch. That’s right. The study revealed that young men who watched too much TV had lower sperm counts than their more active counterparts.

In 2013, the Harvard School of Public Health’s sperm study revealed that men who watched more than 20 hours of TV per week had 44 percent lower counts than men who watched no TV at all. The same study discovered that men who worked out for 15 or more hours per week had much higher counts than those who worked out less than five hours a week. The result showed the men that participated in regular, prolonged exercise had counts up to 73 percent higher than their study counterparts. The findings were published in the British Journal of Sports Medicine.

It is important to note that while the findings are interesting, they are from a relatively small sample of the population. Most experts agree that further study is required before a direct connection is made between the two factors.

One theory is that sitting on the couch squishes the scrotum, raising the temperature and destroying the sperm. Heat has long been touted as a detriment to sperm count, and for good reason, but other studies have disproved this theory, too. As a result, this theory is largely disregarded as nonsense.

A possible contributing factor to these findings is the health of the men involved. Many studies have linked lower sperm counts to men who are overweight. The excess weight interferes with hormone levels required to produce quality sperm in greater numbers. If a person is prone to watching TV rather than exercising, it is logical to assume their weight could be higher than men who exercise more vigorously.

What most experts agree upon, regardless of the validity of the study, the size of the sample or the outlandish nature of the theory, is the idea that there are ways men can boost their sperm numbers by making healthier choices with their lifestyles. By incorporating more activity into their routine and making healthier choices, it appears as if men can boost their personal fertility potential to be at its absolute best — which is essential when trying to conceive.

The key takeaway here? Men suffering from a male infertility diagnosis due to sperm count who are trying to conceive with their partners need to incorporate healthy lifestyle choices. By being more active and not spending their time on the couch, they can increase their sperm count, boost their male fertility levels, and possibly improve their chances of helping their partners get pregnant.
