The WiFi signals from your laptop may be damaging your swimmers, reports a recent study in the journal of Fertility and Sterility. The researchers gathered semen samples from 29 men and placed them underneath a laptop connected to WiFi. After monitoring the semen samples for 4 hours, the results showed that a quarter of the sperm were no longer swimming and 9 percent showed significant DNA damage.
This isn’t the first study that assumed laptops could be frying your fluids. After monitoring subjects who spent 60 minutes with a running laptop on their thighs, State University of New York researchers found that the computer heated up to nearly 104 degrees Fahrenheit—which made the temperatures in the scrotum increase by 66 degrees Fahrenheit.
How exactly does that affect your boys? According to a European fertility study, an increase of 33 degrees Fahrenheit could reduce your sperm count by nearly 40 percent.
“When looking at the big picture, any type of applied heat to the scrotum is bad,” explains Larry I. Lipshultz, M.D., chief of the division of male reproductive medicine and a professor of urology at Baylor College of Medicine. “Men really need to be more conscious when it comes to items such as hot tubs, heating pads, and heated car seats—basically anything that will put direct heat to the scrotum.”
