The posterior scrotal (or labial) branches; superficial peroneal nerves) are two in number, medial and lateral.
They pierce the fascia of the urogenital diaphragm, and run forward along the lateral part of the urethral triangle in company with the posterior scrotal branches of the perineal artery; they are distributed to the skin of the scrotum and communicate with the perineal branch of the posterior femoral cutaneous nerve.
These nerves supply the labium majus in the female.
