Anthropoid Pelvis

The anthropoid pelvis bears a resemblance to the pelvis of the anthropoid ape. The anthropoid pelvis occurs in 20% to 30% of women and is common in men.

Anthropoid Pelvis

Characteristics

1. The anthropoid pelvis is oval-shaped on the inlet, similar to the gynecoid pelvis, but in the anterior-posterior, comparatively in lateral, plane.
2. The subpubic arch may be contracted to some extent.
3. Rather than anterior that is facing the woman’s back presentation, fetal descent through an anthropoid pelvis is more expectable to be in a posterior that is facing the woman’s front.
4. Because of the oval pelvic inlet and long sacrum, the anthropoid pelvis produces a deep pelvis that is wider front to back which is anterior to posterior compared to side to side or transverse.
5. Compared to the android or platypelloid shape, vaginal birth is easier with this pelvic shape.
6. Because of carrying a lot of adipose tissue and fat in the buttocks as well as in the abdomen, women who have this type of pelvis shape have a tendency to have larger buttocks.
7. These women with some effort can have a flat stomach; however, compared to women with the android and platypelloid pelvis types, they may have to decrease body fat levels down slightly lower than average.
