Suppose the corpus spongiosum became as engorged with blood as the corpora cavernosa do during erection of the penis. What problem would this create for sexual function?In light of this, why is it beneficial that the corpus spongiosum is not enclosed in a tunica albuginea?
HEALTHY 42-YEAR-OLD MAN PRESENTED TO THE EMERGENCY DEPARTMENT AFTER THE ACUTE ONSET OF penilepain during sexual intercourse. The erect penis had inadvertently collided with his partner’s perineum. Heheard a snap, noticed a rush of blood from the meatus, had immediate detumescence, and had severe pain. The penile“fracture” refers to a tear in the tunica albuginea, the watertight fibrous outer sheath of the corpora caver-nosa that isresponsible for maintaining the structural integrity of an erection. Disruption of the tunica results in a loss of bloodoutside the corpora, causing a hematoma. The classic eggplant deformity (swelling, discoloration, and deviation awayfrom the defect in the tunica) can be seen. If the fracture involves the urethra, blood will extravasate through theurethra. On the basis of the clinical presentation, the patient was taken to the operating room for emergency repair.The patient had an uneventful postoperative course and was discharged from the hospital the…
