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.)
Latin	saccus profundus perinei

The deep perineal pouch (also deep perineal space) is an anatomical term that refers to the space enclosed in part by the perineum, and located superior to the perineal membrane.

[edit] 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. ^[1]

[edit] Contents

The deep perineal pouch contains:

• muscles
  • Deep transverse perineal muscle
  • External sphincter muscle of urethra
• other
  • Membranous portion of the urethra (males) / proximal portion of urethra (females)
  • Bulbourethral gland (males). (Note: The Bartholin gland is the female counterpart to the bulbourethral gland in males, but it is located in the superficial perineal pouch.)
  • Vagina (females)

[edit] "Urogenital diaphragm"

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