Labeled Radiographic Anatomy & Differences Between Male & Female Pelvis
The male pelvic inlet is narrower than the female pelvic inlet and is more heart shaped, whereas the female pelvic inlet is more circular and wider. In general, the male pelvis is more tall and narrow while the female pelvis is more broad and flattened. Additionally, the angle beneath the ischia bones (the pubic arch) forms a much more acute angle in the male (<90 degrees) while in the female the pubic arch forms an obtuse angle (>90 degrees), and the pubic arch is higher in the male. Additionally, the obturator foramen in the male are round, whereas in the female they are oval.
