Study Notes

Pelvic Bone Characteristics

Female pelvis exhibits lighter, thinner, and smoother bone structure.
Male pelvis presents heavier, thicker bones with prominent markings for supporting a larger build and stronger musculature.

Pubic Arch/Angle

Female pubic arch is wider, ranging from 80 to 90 degrees.
Male pubic arch is narrower, from 50 to 60 degrees.

Acetabula Structure

In females, acetabula are small and positioned farther apart.
In males, acetabula are larger and significantly closer together.

Sacral Features

Female sacrum is characterized by a wider, shorter structure with a pronounced curvature.
Male sacrum is narrower, longer, and features a more ventral sacral promontory.

Coccyx Mobility

Female coccyx is straighter and more mobile to facilitate childbirth.
Male coccyx is less mobile and exhibits a ventral curve.

Pelvic Tilt

The female pelvis tilts forward significantly to support childbirth.
The male pelvis maintains a less forward tilt.

Pelvic Inlet Configuration

Female pelvic inlet is wider and shallower, tailored for childbirth.
Male pelvic inlet is smaller and heart-shaped.

True Pelvis Cavity

Female true pelvis cavity is broad, shallow, and has greater capacity for accommodating childbirth.
Male true pelvis cavity is narrower and deeper.

Pelvic Outlet Shape

Female pelvic outlet is rounded and larger to support birthing.
Male pelvic outlet is smaller in size.
