Perhaps the correlation is the other way around. Men with less testosterone (and therefore a lower sperm count) consume more products with soy, which is common in a vegan diet. Not saying this is the case, just pointing out where this could be coming from.

Are you implying that having low testosterone increases the likelihood of you becoming vegan? I'm not following.

Yes, exactly.

What about having low testosterone would make someone eat more products with soy?
