Two cases of traumatic testicular luxation are described. Patients were a 21 year-old man and a 19 year-old man who were involved in a traffic accident. They were admitted to our hospital with the complaint of right groin mass after the traffic accident. Surgical replacement of the testis, which was dislocated at the right inguinal region, was successfully carried out in both cases. These cases are the 57th and 58th cases of traumatic testicular luxation reported in the Japanese literature.
