Do you want to be a father? Don't use a portable phone

It looks like lovers of cell phones have less chances to faher a child.
After an experiment of exposure to radiation similar to the output of a mobile phone (16 hours), they found a DNA damage in the semen.
"After 16 hours exposure, there was clear evidence of DNA damage," Prof Aitken said.
It does really raise concerns, especially for the ones who, in spite of that, are still able to father a child.
If there are DNA damages, how will the child be?
And I guess the DNA damages won't just be on semen.
