My husband has chewed off an on the whole time we've been together for 9 years. But he wasn't doing it when we conceived our first two boys. Now we are trying for our third and it's been almost a year and I'm wondering if it's because of the tobacco. I know it can lower sperm count and my hubby has had spermatoceles removed in the past so we aren't even sure one of his members even works but we managed to conceive our boys with possibly just one in working order.
