The male pelvis is different from the female pelvis in several features--though some female have more android pelvises and some male have gyneycoid pelvises. However, the main differences between male and female pelvis are the following:
1. The male pelvis is narrower and longer(vertical dimension) and the female pelvis is wider and flatter.
2. The rim of the female pelvis is wider
3. The ilium of the male pelvis(of the false pelvis) is longer and rise higher.
