Misconceptions about falling sperm counts and fertility in Europe
Global baby making seems at no want for a polish, with the world population at 7 billion and rising. But in reality, some evidence suggests part of this picture is breaking down: Sperm may be changing for the worse — at least in some places. The decline has been blamed on everything from cellphones in pockets to hormones in water to fatty food in the Western diet. Evidence for a drop in sperm quality and quantity has included anecdotal reports from sperm banks as well as larger scientific studies. For instance, one sperm bank in Israel says that when it opened its doors , it turned away about a third of the applicants for low quality. Using the same standard today, it would reject more than 80 percent, according to an article in the LA Times.
