[4] Buck's fascia is continuous with the external spermatic fascia in the scrotum and the suspensory ligament of the penis.

On its ventral aspect, it splits to envelop corpus spongiosum in a separate compartment from the tunica albuginea and corporal bodies.

[5] Sources differ on its proximal extent.

[5] The deep dorsal vein of the penis, the cavernosal veins of the penis, and the para-arterial veins of the penis are inside Buck's fascia, but the superficial dorsal veins of the penis are in the superficial (dartos) fascia immediately under the skin.

The name Buck's fascia is named after Gurdon Buck, an American plastic surgeon.
