Yes, we make millions of new sperm a day, but they take months to mature. You can’t just have men avoid cell phones and laptops for a day. Do men randomized to a certain WiFi exposure have a tougher time having children? It’s actually a harder study to perform than one might think. What has yet to be done is a study looking at bouncing baby endpoints. Is a 10 percent decrease in “progressive motile” sperm really going to make a difference? Fertile men release hundreds of millions. Indeed, Wi-Fi exposure may decrease human sperm motility and increase sperm DNA fragmentation, but the effect is minor. That was “the first study to evaluate the direct impact of laptop use on human spermatozoa.” As you can see at 0:43 in my video, the data from human sperm DNA fragmentation levels in samples placed near and far away from a laptop with an active Wi-Fi connection suggest that one might not want to position a Wi-Fi device near the male reproductive organs as that “may decrease human sperm quality.” The title “Use of laptop computers connected to internet through Wi-Fi decreases human sperm motility and increases sperm DNA fragmentation” kind of gives it all away. You don’t really know if Wi-Fi actually damages sperm until you put it to the test, the topic of my video Does Laptop Wi-Fi Lower Sperm Counts?.

“It is impossible to imagine a modern socially-active man who does not use mobile devices and/or computers with Wi-Fi function.” Might cell phones or wireless internet be harmful for male fertility? You may recall that I’ve previously discussed how the sperm of men who use Wi-Fi tend not to get along as swimmingly, but that was an observational study. Should laptops not be on laps? What is the effect of WiFi exposure on sperm motility and DNA damage?
