If a man smokes weed while trying to conceive a baby how could it affect the unborn child?

You can't get pregnant from marijuana! ANSWER::: Ignore the dumbie who wrote before... I think I understand what you are asking. My boyfriend and I have been trying to have a baby for a little over a year. We both smoke marijuana, so I researched this about a week ago. I found that the cannabanoids in pot tend to make sperm less mobile and slower, and it also cause the sperm to not being able to latch onto the female's egg very well. So if you want to get pregnant, then tell your boyfriend you would like him to stop for just a while, and if he says no, there's really not much you can do. But if you love him and still want to be with him, then you can keep trying all you want. That's what my boyfriend and I do.. =] Also, I've known many potheads who do have babies, and many babies at that. I hope I helped a little. :)
