I for one will tell you I'm glad we don't or can't. I think the population would be a lot smaller if it were up to men to give birth. Must see video for both men and women.
Seriously how does this happen? How can you not know you are pregnant? After trying to conceive for four years, Tennessee couple Amanda and Billy Prentice received the happy news that they were expecting.
Then five-hours later Amanda gave birth. True story, see for yourself after the jump.
