[Late results of testis autotransplantation]

Seven patients with bilateral undescended testes (9 intraabdominal testes and 5 inguinal testes), aged 7 to 29 years, were treated surgically. Testis autotransplantation was done for 9 intra-abdominal testes, and cryptorchidopexy was done for 5 inguinal testes. Follow-up for 5 to 9 years showed that the transplanted testes survived except 1 atrophied helf a year after operation. The size of the transplanted was as big as that of international testis model 15, and their hardness was moderate. Obvious improvement of secondary sex character and sexual function were observed in 6 of the 7 patients. The value of serum testosterone was norma (1450-600ng/dl) in 4 patients. In 4 patients, sperms were found in semen. The wives of 2 of those patients bore a boy and a girl respectively in 2-3 years after operation. Operative treatment and optimal age for testis autotransplantation are discussed.
