Cell phones pose risk to men's fertility

Cell phone use impacts fertility of men

Study results released yesterday at the American Society for Reproductive Medicine annual meeting in New Orleans indicate that men who use their cell phones for more than four hours per day may risk lower sperm counts and reduced quality of sperm. A previous study showed a similar correlation between cell phone use and sperm quality but this is a much larger study involving 361 men in Cleveland, Ohio and Mumbai, India. Men who used a mobile phone for more than four hours a day had a 25 per cent lower sperm count than men who never used a mobile. And men with highest usage also had greater problems with sperm motility and a 50 per cent drop in the number of properly formed sperm. Researchers are speculating that the cause of the drop in sperm count and quality could be the result of electromagnetic radiation, heat, or hormone changes. But the precise mechanism is not known and there is certainly the possibility that cell phone use and some other behavioral or environmental factor that is causing the fertility impact are strongly correlated.
