Poor sperm with the mobile phone?

The men who use mobile phones face increased risk of infertility.

A new study shows a worrying link between poor sperm and the number of hours a day that a man uses his mobile phone. A men who made calls on a mobile phone for more than four hours a day had the worst sperm counts and the poorest quality sperm! Well, it seems impossible!

Doctors believe the damage could be caused by the electromagnetic radiation emitted by handsets or the heat they generate. Men who used a mobile for more than four hours a day had a 25% lesser sperm count than men who never used a mobile and the people who use phones for longer might be more sedentary, more stressed or eat more junk food, which might be more likely explanations for the link found in the study.

But well, the mobile is very necessary in this moment and I think that in the future will be even more necessary...Do you agree with me?
