Actually, studies done on pain tolerances shows that a pregnant women's pain tolerance goes up sharply as childbirth approaches, and then drops back down to normal levels after childbirth. In addition I'm pretty sure I read that on average females have a lower pain tolerance then men. Though it can be changed by training... relatively easily too.
