What is the Difference Between Male and Female Pelvis?
🆚 Go to Comparative Table 🆚The male and female pelvis have several differences that can be attributed to their respective functions, such as childbirth in females and locomotive efficiency in males. Key differences between male and female pelvises include:
- Size and shape: Female pelves are generally larger and wider than male pelves, with a rounder pelvic inlet. Male iliac crests are higher, causing their false pelves to appear taller and narrower. The female pelvis has evolved to its maximum width for childbirth, while the male pelvis is optimized for efficient locomotion when walking upright.
- Sacrum: The male sacrum is longer, narrower, and straighter than the female sacrum, with a more pronounced sacral promontory.
- Pelvic outlet: The female pelvic outlet is larger and oval-shaped, while the male pelvic outlet is heart-shaped and narrower.
- Coccyx: The male coccyx is projected inwards and immovable, while the female coccyx is flexible and straighter.
- Pubic arch: The male pelvis has a V-shaped pubic arch with an angle of approximately 70°, while the female pelvis has a wider pubic arch with an angle of about 80°.
These differences reflect the unique adaptations of the male and female pelvises to their respective functions, such as childbirth in females and locomotive efficiency in males.

Comparative Table: Male vs Female Pelvis
Here is a table comparing the differences between male and female pelvises:
| Feature | Female Pelvis | Male Pelvis |
|---|---|---|
| Size and Shape | Larger, wider, and more compact | Taller, narrower, and more elongated |
| Iliiac Crest | Lower iliac crest | Higher iliac crest |
| Pelvic Inlet | Larger, oval-shaped, and wider | Smaller, heart-shaped, and narrower |
| Pelvic Outlet | Smaller, rounder, and wider | Larger, oval-shaped, and more narrow |
| Subpubic Angle | Larger angle (>80 degrees) | Smaller angle (<70 degrees) |
| Pubic Arch | More rounded and wider (> 80 degrees) | Less rounded and narrower (< 70 degrees) |
| Coccyx | Coccyx is more projected outwards and immovable | Coccyx is more tucked inwards and movable |
The female pelvis is adapted for childbirth, which is why it is wider and larger than the male pelvis. The male pelvis, on the other hand, is designed to support a heavier body build and stronger muscles, making it thicker, heavier, and more compact.
