Thanks for the insight Janusface! But they have most likely used the same equipment today comparing western and non-western men. And comparing to them we have low sperm count. And other research point to that we have something like 50-60% lower testosterone levels than our parents! (gen-x'ers compared to baby boomers) I think it would be strange if not hormones and our food, water, soil etc and the compounding chemicals that we now have in our bodies don't have any sort of unknown cocktail-effect. But the feminization cubicle-theory could play a much bigger role (and of course it's a lot more fun explanation)
