Corpus: Puboprostatic ligament

The puboprostatic ligament is a ligamentous connection between the symphysis pubica and the prostate. It fixes the urinary bladder (vesica urinaria) and prostate to the bony pelvic ring and delimits the spatium retropubicum caudally.

In addition to collagen fibres, the puboprostatic ligament contains strands of smooth muscle that separate from the outer longitudinal muscle layer of the bladder wall and are delimited as the puboprostatic muscle.

The puboprostatic ligament originates on the lateral side of the prostate and attaches to the dorsal edge of the pelvic symphysis. It only occurs in men and corresponds to the female pubovesical ligament. Caudally, the ligament borders the spatium retropubicum.

The puboprostatic ligament surrounds the prostate with the neck of the bladder and fixes its position.
