Our bodys have grown, there would be no way of changing the DNA in every cell of your body now that we are fully grown. This DNA editing would have to be done to unborn children for later generations. To make this work you would have to change the DNA of a sperm or egg while it is still one cell. Then when the egg multiplies cells the whole body has the new DNA instead of only a few of your cells.
It is very unlikely that tampering with DNA will make us not be able to reproduce, that is just TV. I'm not saying there in no chance of side effects, but I'm sure they wouldn't be that major.
