A study has been carried out by Ashok Agarwal, PhD on last 2007 - 2008 about the relationship between cell-phone usage by men and the fertility. As all we know that there is radiation produced by the cell phone especially during receiving a call.
In general, most of men will place or store their phone inside their trousers' pocket. Trousers' pocket is very near with the male genitalia. While receiving a call or receive a message, the wave that connected to the cell phone will produced radiation. It will affect fertility of sperm for that person. Therefore, men should take precautions action by minimize put or store phone inside their trousers' pocket. It atleast can reduce the effect of the radiation toward male genitalia.
Our next generation is up to what we do right now. If fertility is not so good, it will affect the survival of the next generation. Therefore, act now before its too late. Prevention is better than cure.
