In the past, male infertility studies have focused on the fact that elevated temperatures in a man’s testicles due to a laptop sitting on his lap can affect the quality of his sperm. But a new study out of Argentina, published in the medical journal Fertility and Sterility, has found a larger concern — the effect on sperm situated very near a Wi-Fi-connected laptop.
The study found that semen samples placed under a laptop connected to the Internet experienced more DNA damage and mobility issues than regular sperm. After four hours sitting about an inch below a Wi-Fi-connected laptop, 25 percent of the sperm samples lost their mobility and 9 percent showed defects in their DNA — three times more than the control samples, which were kept at the same temperature but away from the Wi-Fi.
The study also tested the sperm next to laptops that were not connected to Wi-Fi. They showed some damage, but less than the connected laptops, which reinforces the previous studies about how the mere heat of the laptop could impact male fertility.
More research needs to be conducted to learn the true effects of electromagnetic radiation generated by a laptop’s Wi-Fi connection, but it’s a good idea for all men to take precautions — such as using special laptop desks and laptop fans — when using laptops.
