Which statement is true about pubococcygeus composition?

• A. In females, pubococcygeus comprises puborectalis and pubovaginalis.
• B. In females, pubococcygeus comprises puborectalis and puboprostaticus.
• C. In males, pubococcygeus comprises puborectalis and pubovaginalis.
• D. In males, pubococcygeus comprises pubovaginalis and pubprostaticus.

Answer: (A)

The pubococcygeus is a portion of the levator ani that includes fibers around the anorectal region (puborectalis) plus a sex-specific slip that reinforces the urogenital area. In females, the distal component that aids vaginal support is pubovaginalis. So, together, puborectalis and pubovaginalis constitute the pubococcygeus in females. In males, the corresponding distal slip is puboprostaticus, not present in females. This makes the statement describing females as having puborectalis plus pubovaginalis the correct one.
