According to researchers in Argentina, man's supposed new best friend, the innocuous laptop, could seriously affect male fertility. In simulated tests, the sperm of 33 volunteer were all negatively affected. The mobility of the semen diminished and the breakdown of its DNA increased. While tests have yet to be conducted on female subjects, the discovery suggests the devices potentially reduces a man's fertility and increases the danger of genetic deformities in children who are born.
