I did not know this. In fact, I’ve never heard these terms.
The female human pelvis has been classified according to shape; specifically to highlight how easily a fetus can be delivered. Gynecoid is the optimum type. The Android pelvis is more “male” but still suitable to pregnancy and birth although there may be problems. Anthropoid indicates “ape-like” and Platypelloid means “flat oval” – “wide hips.”
Individual women have variations that gradate between these types.
