It was something I saw many years ago on NHK as one theory of why human sperm quality keeps deteriorating. As far as I'm concerned, it makes sense to me. Remove more and more factors that would encourage healthier sperm and it's only natural that our sperm will deteriorate.

As others have said, the decline is much too rapid in the last couple of decades for it to be explained by evolution. It sounds more like a theory spouted by chemical-/food-/etc companies who worry about getting the blame.
