I remember reading and article years ago about this an it stated that the only country in the West where sperm count hadn't fallen was Finland and there was a study to try and find what they were doing that was different but mainly a look at their diet , if i can remember correctly. I suspect preservatives in the food and also all the shit they spray on the food perhaps has something to do with it and also the amount of radiation we are now exposed by wifi wont help . More reacently I read that the chemicals that they have in fabric saftner are not good for male bits. .
There was a study in London years ago about the amount of esrtogen in the water supply due to all the wimen on the pill . Certainly , one thing that isnae good fur guys is a ton o' estrogen in the water which might be why so many folk there dont know if they are fish or fowl . .
