Sperm-eggso says an Jan 2012 article in the Fertility and Sterility Journal.

I’ve written before about the risks of burns when using laptops.  This is something new.

The article basically says that using a WiFi will, if you’re a male:

  1. damage the DNA in the sperm.
  2. reduce the ability of the sperm to swim, which impacts fertility.
