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.

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.Netter, F., Atlas of Human Anatomy.4th Ed. Saunders, Philadelphia, 2006. The deep pouch is now described as the region between the perineal membrane and the pelvic diaphragm.Netter, F., Atlas of Human Anatomy.5th Ed. Saunders, Philadelphia, 2010.

The deep perineal pouch contains:

muscles
Deep transverse perineal muscles
External sphincter muscle of male urethra
External sphincter muscle of female urethra
Compressor urethrae muscle in the female is sometimes includedEssential Clinical Anatomy – 4th Edition. p.255
Urethrovaginal sphincter in the female is sometimes included
other
Membranous urethra in the male; proximal portion of urethra in the female
Bulbourethral gland (males). The Bartholin gland, the female counterpart, is in the superficial perineal pouch
Vagina (females)

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.
