Thanks. Just trying to equal the bad guys with some good stuff. The reason for the fertility issue is contraception used by women. It is everywhere. When a woman urinates it goes to canalization, then the water cleaners cannot effectively avoid it so it goes to the rivers, then to fish and in the end to humans. I think it is called estradiol which can be processed in our body into estrogen the female hormone which makes men infertile. I am pretty sure you can find many information online.
