Sex Differences
Female and male pelvises usually differ in several ways, including the following:
1) Female iliac bones are more flared than those of the male; therefore, the female has broader hips.
2) The female pelvis is wider between the ischial spines and the ischial tuberosities.
3) The female inlet and outlet of the true pelvis are wider.
4) The female pelvic cavity is more shallow, while the male pelvic cavity is more funnel-shaped.
5. Female bones are lighter and thinner.
6. The female pubic arch (angle at the pubic symphysis) is wider.
In addition to these differences in pelvic structure, male pelvic bones are larger and heavier, the articular ends are thicker, and the points of muscle attachment may be larger.
The female pelvis is generally wider and more shallow than the male pelvis.
