Deep perineal pouch

The deep perineal pouch (also deep perineal space) is the anatomic space enclosed in part by the perineum, and located superior to the perineal membrane.

Deep perineal pouch
Coronal section of anterior part of pelvis, through the pubic arch. Seen from in front. (Deep perineal pouch not labeled, but is between the "superior layer" and "inferior layer" labeled at bottom left.)
Vertical section of bladder, penis, and urethra. (Cowper's gland and membranous portion of urethra visible at center bottom.)

Anatomical terminology


The deep perineal pouch is bordered inferiorly by the perineal membrane, also known as the inferior fascia of the urogenital diaphragm. It is bordered superiorly by the superior fascia of the urogenital diaphragm.[1] The deep pouch is now described as the region between the perineal membrane and the pelvic diaphragm.[2]


The deep perineal pouch contains:

"Urogenital diaphragm"

Older texts have asserted the existence of a "urogenital diaphragm", which was described as a layer of the pelvis that separates the deep perineal sac from the upper pelvis. The deep perineal pouch lies between the inferior fascia of the urogenital diaphragm and superior fascia of the urogenital diaphragm.
