Laptops sterilise males -

Argentine boffins have worked out that wif-fi laptops are jolly good at reducing a bloke's carbon footprint by preventing  them from fathering children.

Radiation emitted by an internet-connected computer resting on the user’s legs reduces sperm mobility and fragments DNA.

The study was carried out by Nascentis, a reproductive medicine centre located in Córdoba, Argentina. The results of the study will be presented at the 66 Congress of the American Society for Reproductive Medicine (ASRM) taking place in October in Denver, USA.

Top boffins  Conrado Avendaño, a biochemist specialising in andrology, Ariela Mata, reproductive biology specialist and César Sánchez Sarmiento, director of the medical centre found out that sperm just don't move very well when exposed to the radiation from wi-fi laptops.

According to a report published in the Córdoba newspaper “La Voz” (in Spanish) they had a look at the baby gravy of healthy donors with no history of recent illnesses. One of the sub-samples was incubated under a laptop connected to the internet to replicate the conditions that occur when a bloke places the computer on his lap.

After four hours of cooking the sample exposed to the laptop a large percentage of the sperm cells were affected.

Although the wi-fi did not kill the sperm cells,  it seemed it scrambled their DNA integrity which might prevent them from doing much in their short lives.
