In adult females the pelvis is shaped differently from males. The differences are connected with allowing the baby to pass through the birth canal successfully. Also, during pregnancy, a hormone called relaxin softens the ligaments in the pelvis area. This produces a little bit of extra space for the baby's head to get through. The process is hard to describe in words, but fortunately there is an excellent video which explains what goes on.
