The posterior or lateral superficial perineal nerve, at the anterior limit of the ischio-rectal fossa, usually passes over the base of the urogenital diaphragm and over the (superficial) transversus perinei muscle. The anterior or medial superficial perineal nerve, lying more deeply, pierces the base of the fascia iuferior of the urogenital diaphragm and goes underneath or through the transversus perinei muscle.
