Bad news: Wi-Fi laptops may be nuking your sperm

In a report in the venerable medical journal Fertility and Sterility, Argentinian scientists describe how they got semen samples from 29 healthy men, placed a few drops under a laptop connected to the Internet via Wi-Fi and then hit download.

Four hours later, the semen was, eh, well-done.

A quarter of the sperm were no longer swimming around, for instance, compared to just 14 percent from semen samples stored at the same temperature away from the computer.

And nine percent of the sperm showed DNA damage, three-fold more than the comparison samples.
