Soy and marijuana affecting fertility?

Laura

My husband and I have been ttc for about 2 years now. We have a son and he is 4 and when we got pregnant we both drank a lot more alcohol, smoked weed and ate a lot worse. We had no problems getting pregnant the first time. Since having our son we both have gotten much healthier. I am vegan and my husband is mostly vegan. We don't drink nearly as much and don't smoke at all. We recently found out that my tubes are blocked and he has abnormal sperm. He thinks that the increase of soy in our diet might be the reason for his issue. He made a joke that he should just go back to smoking weed again but I've always heard that weed was bad for sperm. The soy is a new one for me. Anybody have any ideas or advice on soy or marijuana affecting fertility especially in men?
