title: [Contribution to the study and treatment of cryptorchism].
abstract: Multiple series of undescended testes reported in the 1970's shown a significant decrease in spermatogonia content and tubular growth. After that most pediatric surgeons perform elective orchiopexy earlier. Pathologic studies in undescended testes shown significant complications. We studied 82 patients who were surgical treated between 1 to 13 years and we studied the tubular fertility index (TFI), mean of tubular diameter and Sertoli cells index (SCI). We found no correlation between age of patients and lesions. In our point of view the alterations of undescended testes is secondary to primary disease no to remain out of the scrotum. Current evidence suggests that the optimal time for performing orchiopexy is between four to seven years.
