Warning to male mobile phone users: chatting too long may cut sperm count

Researchers found sperm quality fell with increased mobile phone usage.

Men who use mobile phones for long periods at a time may be at risk of damaging their sperm, according to research by American scientists. Samples taken from men attending a fertility clinic revealed that their sperm declined steadily in number, quality and ability to swim as mobile phone usage increased. Where men used their mobiles for more than four hours a day, researchers found a 30% drop in sperm motility or movement and viability when compared with men who did not use a mobile phone.
