A computer with a wireless Internet connection hurts sperm, but not because the machine can heat up your lap, a new study suggests.

“Wi-fi radiation kills, harmed sperm — Care your Health from Technology”

After four hours of exposure, one-quarter of the sperm were no longer swimming — Reuters reported. In comparison, 14 percent of sperm cells that had been kept at the same temperature but not exposed to wi-fi were no longer swimming. What's more, DNA damage was more common in the wi-fi sperm than in the "control" sperm.

In a control test — with the sperm kept away from WiFi emissions, but at the same under-laptop temperature — 14% of the sperm died within four hours, and 3% showed DNA damage. When placed underneath a laptop for four hours, 25% of the sperm died and 9% showed DNA damage. The important finding here is that WiFi electromagnetic (EM) radiation damaged the sperm — almost every other study has focused on increased temperature (which also damages sperm, incidentally).
