What is another name for the rectouterine pouch?

The rectouterine pouch, which is the space between the rectum and the posterior wall of the uterus, is commonly referred to by two different names: Douglas's Pouch and Cul-de-sac.

Douglas's Pouch is named after Dr. James Douglas, the Scottish anatomist who is credited with its discovery. The term "cul-de-sac" is a French term meaning "bottom of the bag," which descriptively refers to this anatomical space as it resembles a pouch or sac where fluid can accumulate.

Both names highlight the anatomical nature of this space within the female pelvis, where clinical examinations, imaging, or surgery might identify fluid collections or pathologies. Recognizing these synonyms is essential for understanding discussions related to gynecology and pelvic anatomy.
