APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Females have a subpubic angle that is wider (larger, more obtuse) than males, measuring around 80 degrees or more. The answer is A, true. The female pelvis has a subpubic angle that is generally greater or equal to 80 degrees, which makes it broader than the male’s pubic arch .

Detailed explanation-2: -Compared to the male, the female pelvis is wider to accommodate childbirth. Thus, the female pelvis has greater distances between the anterior superior iliac spines and between the ischial tuberosities. The greater width of the female pelvis results in a larger subpubic angle.

Detailed explanation-3: -A subpubic angle of 50–82 degrees indicates a male; an angle of 90 degrees indicates a female. Other sources operate with 50–60 degrees for males and 70–90 degrees in females. Women have wider hips, and thus a greater subpubic angle, in order to allow for child birth.

Detailed explanation-4: -A male pelvis has a v-shaped pubic arch that is approximately <70°. The pubic arch is usually wider in the female pelvis at about >80°. The coccyx in the male pelvis is projected inwards and immovable while a female pelvis has a flexible and straighter coccyx.
