Rectovesical excavation

Between the rectum and the bladder the peritoneal cavity forms, in the male, a pouch, the rectovesical excavation (or rectovesical pouch), the bottom of which is slightly below the level of the upper ends of the vesiculae seminales—i. e., about 7.5 cm. from the orifice of the anus.

The corresponding structure in women is the rectouterine pouch.
