Injuries to the Penis and Scrotum

> >

by Noel A. Armenakas, MD

Several types of injuries can affect the penis. The penis can be partially or fully severed. Reattachment of a severed penis is sometimes possible, but the extent of recovery of sensation and function varies. Constricting penile rings, applied to enhance erections, can possibly strangle the penis and cause permanent damage. Removing the ring is usually all that is necessary. Penetrating injuries, including animal bites and gunshot wounds, are less common and may also involve the urethra. Surgery may be required to treat injuries of the penis and urethra.

Cuts to the penis

Catching the penis in a pants zipper is common, but the resulting minor cut usually heals quickly. Cuts usually heal quickly if they are simply kept clean, but antibiotics should be taken if the cuts become infected.

Fracture of the penis

Excessive bending can fracture an erect penis. Such bending may occur during vigorous sexual intercourse if the penis is stubbed against the partner’s pelvic bone. The “fracture” is actually a tear in the covering of one of the two tube-like structures in the penis (corpus cavernosum) that hold the extra blood flow that maintains erection.

The man has immediate pain, swelling, and discoloration, and the penis appears deformed. Prompt surgery is usually necessary to repair such fractures to prevent abnormal curvature of the penis or permanent erectile dysfunction.

Injury of the scrotum and testes

The location of the scrotum makes it susceptible to injury. Blunt forces (for example, a kick or crushing blow) cause most injuries. However, occasionally gunshot or stab wounds penetrate the scrotum and testes. Rarely, the scrotum can develop severe and rapidly progressive infections such as gangrene. If gangrene develops, the involved tissues are surgically removed and the man is given antibiotics by vein (intravenously). Reconstructive surgery can be done after the infection is controlled.

Testicular injury causes sudden, severe pain, often with nausea and vomiting. Ice packs, a jockstrap, and drugs for pain and nausea usually effectively treat a bruised testis (bleeding in and around the testis). Ultrasound examination may show whether the testes have ruptured. Ruptured testes require surgical repair. Injury to the testes can destroy the capacity for sex hormone (mainly testosterone ) or sperm production. If both testes are injured, testosterone replacement may be necessary. If only one testis is injured, the remaining testis usually produces as much testosterone as the body needs.
