Superficial Perineal Pouch

Superficial perineal pouch is a compartment of the perineum lying between the perineal membrane and urogenital diaphragm.

Boundaries and borders:

Inferiorly, the superficial perineal pouch is bounded by membranous layer of perineal superficial fascia (Fascia of Colles). Superiorly, it is bounded by the urogenital diaphragm.

The pouch is closed behind by the fusion of its superior and inferior boundaries. Laterally, it is closed by the attachment of the membranous layer of superficial fascia and urogenital diaphragm to the margins of pubic arch.  Anteriorly, it communicates with the potential space between the superficial fascia of anterior abdominal wall and abdominal muscles.


Superficial perineal pouch has the following contents:

  • Crura of penis (in males) or clitoris (in females)
  • Bulb of penis (in males) or vestibular bulbs (in females)
  • Greater vestibular glands (only in females)
  • Ischiocavernosus muscle
  • Bulbospongiosus muscle
  • Superficial transverse perineal muscle
