For a recent study, researchers obtained semen samples from 29 healthy men and placed the samples under a laptop connected to the Internet via Wi-Fi. Four hours later, a quarter of the sperm were no longer swimming, compared to just 14 percent from a control sample. In addition, 9 percent of the sperm showed DNA damage, three times the amount of damage found in the comparison samples.
The cause was electromagnetic radiation generated during wireless communication.
MSNBC reports:
“The findings fuel concerns raised by a few other research teams. Some have found that radiation from cell phones creates feeble sperm in the lab, for example. And last year urologists described how a man's sitting with a laptop balanced on his knees can crank up the temperature of his scrotum to levels that aren't good for sperm.”
