Summarized information about male pelvis & female pelvis.
Focused on differences between male and female pelvis.

The pelvis is one of the most useful skeletal elements for differentiating between males and females. 

Like the skull, the pelvis is highly useful for determining a skeleton’s biological sex. 

〇 Pelvic cavity shape and size: 
The female pelvis is wider and more shallow than the male pelvis, with a greater distance between the iliac crests. This is because women need a wider pelvic cavity to accommodate childbirth.

〇 Pelvic outlet: 
The female pelvic outlet is larger and more oval-shaped than the male pelvic outlet, which is smaller and more heart-shaped. This allows for easier passage of the baby during childbirth.

〇 Pubic arch angle: 
The angle between the pubic bones is wider in females than males. This is important for accommodating the baby's head during childbirth.

〇 Sacrum: The female sacrum is shorter, wider and less curved than the male sacrum, which is taller, narrower and more curved. This is because the female sacrum needs to accommodate childbirth.

〇 Coccyx: The female coccyx is more moveable and angled backward, while the male coccyx is more rigid and angled forward. This also facilitates childbirth.

〇 Ischial tuberosities: The female ischial tuberosities are farther apart and more everted than the male ischial tuberosities, which are closer together and more straight. This allows for greater support of the baby's weight during childbirth.

Overall, these differences allow the female pelvis to accommodate childbirth and the male pelvis to support the weight of the upper body and to provide attachment sites for muscles involved in locomotion.
