Detailed explanation-1: -The pelvic bones in males are narrow, and the cavity is heart-shaped. The pelvic bones in the females are broader, and the cavity is oval-shaped to support childbirth.

Detailed explanation-2: -Within the same population, males tend to have larger, more robust bones and joint surfaces, and more bone development at muscle attachment sites. However, the pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing.

Detailed explanation-3: -Female pelves are larger and wider than male pelves and have a rounder pelvic inlet. Male iliac crests are higher than females, causing their false pelves to look taller and narrower. The male sacrum is longer, narrower, straighter, and has a pronounced sacral promontory relative to the female sacrum.

Detailed explanation-4: -The sciatic notch is a large notch in the pelvis located above the ischial spine. In females, this sciatic notch is wider whereas in males, it is narrower. The subpubic angle is located at the inlet of the pelvic. It also observes the same pattern; in females the subpubic angle is wider and it is narrower in males.

Detailed explanation-5: -MALE BONES ARE BIGGER AND STRONGER, in both size and density. Peak male bone mass is around 50% more than women’s, and women lose bone faster as we age. WOMEN AND MEN HAVE THE SAME NUMBER OF RIBS.
