Answer

The contents of the scrotum, namely the testicles, epididymides, and cord structures, are invested by several fascial layers distinct from the Dartos fascia of the scrotal wall. Again, several important anatomic relationships should be considered.

The most superficial layer of the testis and cord is the external spermatic fascia, which is continuous with the external aponeurosis of the superficial inguinal ring (external abdominal oblique). The next deeper layer is the internal spermatic fascia, which is continuous with the transversalis fascia. A deep fascia termed Buck fascia covers the erectile bodies of the penis, the corpora cavernosa, and the anterior urethra. Buck fascia fuses to the dense tunica albuginea of the corpora cavernosa, deep in the pelvis.

The fascial layers described in this section do not become involved with an infection of the superficial perineal space and can limit the depth of tissue destruction in a necrotizing infection of the genitalia. The corpora cavernosa, urethra, testes, and cord structures are usually spared in Fournier gangrene, while the superficial and deep fascia and the skin are destroyed.
