Male external genitalia and perineum
Suspensory ligament of penis, left lateral view
The specimen shown in the preceding view has been turned to expose the left side of the penis. The suspensory ligament (1) is continuous inferiorly with the deep fascia of the penis. It also receives parts of the insertions of the ischiocavernosus and bulbospongiosus muscles (18). The thick tunica albuginea of the left crus of the penis has been removed to reveal the erectile tissue of the crus.
