My boyfriend and I have recently began to start the process of trying to have a baby. He drinks about 4 beers about every other day. Its this OK or will it cause a problem with his sperm count? Can anyone help me? I've tried to Google but it didn't give me any direct answers. This is what we want but I want to be sure before I tell him he had to leave the beers alone until we get what we want. Thanks in advance. :)

It can lower sperm count, as does tight underwear, getting into the hot tub and many things.
It will not stop it, but it can lower counts
