title: Pathological changes of traumatic dislocated testis.
abstract: We present a 17-year-old patient with a right testicular dislocation. In this case, dislocated testis had been considered as hematoma and therefore remained untreated for 4 months. The patient underwent right orchiopexy 4 months after the injury. Intraoperative testicular biopsy revealed impaired spermatogenesis and existence of many alternative Sertoli cells, but no atrophy of seminiferous tubules. Six months after the operation, semen analysis of the patient revealed the deformity of most sperms. Eight months after the operation, rebiopsy of the right testis disclosed slight improvement in the spermatogenesis of the testis. Damage of the testis appears to be not severe in dislocation and may be recovered by repositioning.
