You may recall being told to keep your laptop off of your lap to prevent the heat from
damaging your sperm count, but
you may not know that even a computer's Wi-Fi connection can hinder male fertility. A recent study published in the
journal Fertility and Sterility
collected 29 sperm samples from healthy men that were placed underneath laptop with a
wireless Internet connection for four hours. Researchers set the laptop to download and upload information so its Wi-Fi
was in constant use. To prove that temperature wasn't the only factor
effecting sperm quality, an air-conditioning
system was used to keep the laptop at 77 degrees. Radiation from the laptop's Wi-Fi connection caused DNA damage and
less motility in sperm.
