Laptop Wi-Fi said to nuke sperm -
The digital age has left men's nether parts in a squeeze, if you believe the latest science on semen, laptops and wireless connections.
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.
The culprit? Electromagnetic radiation generated during wireless communication, say Conrado Avendano of Nascentis Medicina Reproductiva in Cordoba and colleagues.
"Our data suggest that the use of a laptop computer wirelessly connected to the internet and positioned near the male reproductive organs may decrease human sperm quality," they write in their report.
"At present we do not know whether this effect is induced by all laptop computers connected by Wi-Fi to the internet or what use conditions heighten this effect."
