The deep perineal pouch (also deep perineal space) is the
anatomic space enclosed in part by the
perineum
The perineum (: perineums or perinea) in placentalia, placental mammals is the space between the anus and the genitals. The human perineum is between the anus and scrotum in the male or between the anus and vulva in the female. The perineum is ...
and located superior to the
perineal membrane.
Structure
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. The deep pouch is now described as the region between the perineal membrane and the
pelvic diaphragm.

Urogenital diaphragm
Older texts have asserted the existence of a "
urogenital diaphragm", which was described as a layer of the
pelvis
The pelvis (: pelves or pelvises) is the lower part of an Anatomy, anatomical Trunk (anatomy), trunk, between the human abdomen, abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also c ...

inferior fascia of the urogenital diaphragm and
superior fascia of the urogenital diaphragm.
