Testicular autotransplantation after traumatic castration.

Severe genitoperineal trauma with total avulsion of testicles in a 7-year-old boy resulted from a road accident. Soft tissues were reconstructed by local flaps and skin grafts. The only testicle that was found was reimplanted in his biceps muscle in an attempt to restore endocrine function. A human chorionic gonadotropin test showed no response, indicating that the transplanted tissue did not survive.
