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]
Colles' fascia emerges from the perineal membrane, which divides the base of the penis from the prostate. Colles' fascia emerges from the inferior side of the perineal membrane and continues along the ventral (inferior) penis without covering the scrotum. It separates the skin and subcutaneous fat from the superficial perineal pouch.
The perineal membrane is an anatomical term for a fibrous membrane in the perineum. The term "inferior fascia of urogenital diaphragm", used in older texts, is considered equivalent to the perineal membrane. It is the superior border of the superficial perineal pouch, and the inferior border of the deep perineal pouch.
The muscles surrounded by the deep perineal fascia are the bulbospongiosus, ischiocavernosus, and superficial transverse perineal. The fascia is attached laterally to the ischiopubic rami and fused anteriorly with the suspensory ligament of the penis or clitoris. It is continuous anteriorly with the deep investing fascia of the abdominal wall ...
Bulbourethral glands are located posterior and lateral to the membranous portion of the urethra at the base of the penis, between the two layers of the fascia of the urogenital diaphragm, in the deep perineal pouch. They are enclosed by transverse fibers of the sphincter urethrae membranaceae muscle.

However, while Bartholin's glands are located in the superficial perineal pouch in females, bulbourethral glands are located in the deep perineal pouch in males. Their duct length is 1.5 to 2.0 cm and they open into navicular fossa. [2] The ducts are paired and they open on the surface of the vulva. [3]
This is the narrowest part of the urethra. It is located in the deep perineal pouch. The bulbourethral glands (Cowper's gland) are found posterior to this region but open in the spongy urethra. Pseudostratified columnar: Spongy urethra (or penile urethra) Runs along the length of the penis on its ventral (underneath) surface.
