The Differences Between the Male and Female Pelvis

Recently I shared a case of Peyronies disease. Many people thought it was showing an intrauterine device. Therefore, I created the following image to discuss the differences between the female and male pelvis.

Side by side images of the pelvis (Female on the left with pink line, male on the right with blue line). Note the Peyronie's disease on the right in the man's penis, and a normally positioned intrauterine device on the left.

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.

Read about variations in the obturator foramen and pubic arch in the female bony pelvis here.

The intrauterine device image above is from RadioGraphics here.
