[Late results of testis homotransplantation].

15 patients with testis dysplasia and traumatic anorchidism were treated with testis homotransplantation. 14 of 15 cases have been followed up for 1.5 to 5 years. The transplanted testes of 14 cases were with moderate hardness and obvious improvement of secondary sex characters and sexual function have been observed in these patients. The size of the transplanted testes was as big as that of international testis model 15 in 11 cases. The transplanted testes of 3 cases atrophied 9 to 14 months after operation. The sperms were found in semen or urine collected from the bladders after prostatic massage in 3 cases. Sperm count and sperm motility were normal in 2 cases. The wife of 1 case was impregnated and bore a boy in the fourth year after operation. The value of serum testosterone became normal (450-900 ng/dl) from preoperative low level. Therapeutic effectiveness of testis homotransplantation was evaluated and treatment of rejective reaction of the testis homotransplantation was discussed in the paper.
