Laptops damage sperm? What wi-fi study shows

(CBS) Do laptops reduce men's fertility? There's some evidence that heat from laptops can interfere with sperm production, and now a new study links the electromagnetic radiation emitted by wi-fi-enabled laptops to sperm damage.

For the study - published in the journal Fertility and Sterility - researchers in Argentina obtained semen from 29 healthy men and measured sperm cells' swimming ability after being exposed to wi-fi radiation from an Internet-connected laptop.

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.     More Read
