In women, the swaying of the hips is much more marked than in men. This difference is due to the pelvis , which arises from the union of three bony pieces: the sacrum, which distributes the weight of the spine between the two legs through the two hip bones -left and right- or iliac bones. .
At puberty , the female pelvis undergoes an interesting procreation-oriented transformation. Yes, the hip widens to allow the baby to pass, and the pubis dilates and sags to form the birth canal. This causes the femurs of women to arch and give the women a somewhat special movement of the hips.
