Sorry, gentlemen— even though a WiFi signal may be strong, that sperm count may be pretty weak. According to a new study in the journal Fertility and Sterility, the electromagnetic radiation generated from surfing the web using WiFi may be killing semen. In a modest-sized study (relax, we’re talking number of participants), researchers took semen samples and placed them under laptops connected to wireless Internet. Four hours later, the wireless had zapped the life out of a quarter of the sperm cells (whereas only 14 percent of the swimmers sitting away from the computer perished). 

Yet, before plugging those Ethernets back in, remember this study created an artificial environment, since scientists placed sperm directly under laptop computers. Scientists can’t be certain a late night Hulu movie with a partner won’t result in, er, difficulties once the credits roll. To err on the side of caution, guys, distance the laptop from those ever-precious organs, and simply place the computer on a desk! And don’t forget that a daily dose of veggies with a side of physical activity is another effective way to keep those sperm swimming!
