The Difference Between the male and female Pelvis
The biggest difference between the two is the pelvic inlet, and the pubic arch. There is only one reason for theses to be different. The purpose that these dimensions are greater than the male pelvis is because of child birth. The baby has to be able to come throuh the pelvic inlet, and the size of the males is just to small so the inlet is larger in females, and that is also the reason the pubic arch is wider.
