    Abstract:
    PURPOSE: Cryptorchidism is a well-defined risk factor for testicular germ cell tumors, whereas the underlying mechanisms have not been fully elucidated. Surgical procedures to reposition undescended testicles into the scrotum (orchidopexy) in early childhood are recommended both to increase fertility potential and to reduce the risk of developing testicular tumors. However, treatment in the post-pubertal period is controversial. The aim of this study is to review the histopathology of orchiectomy specimens and determination of spermatogenesis in post-pubertal patients with non-treated cryptorchidism. METHODS: Retrospective chart review was performed to assess the occurrence of TGCTs and determine spermatogenesis in post-pubertal individuals who underwent inguinal orchiectomy for undescended testis between January 2010 and December 2019. Age at the time of surgery, laterality, location of the undescended testis and pathology results were evaluated. All pathology specimens were reviewed by a blinded pathologist. RESULTS: There were 23 patients in the cohort with a mean age of 21 years (range 13-46 years). All testes were in the inguinal canal. Our results indicated that 1 patient had seminoma. In the histological evaluation of the remaining 22 patients in whom no tumor was detected, normal spermatogenesis was not observed in any patient. Further, seminiferous tubules were not found in 19 patients. Maturation arrest was detected in the remaining 3 patients. CONCLUSION: Testicular germ cell carcinoma was found in 4% of the patients who underwent post-pubertal orchiectomy. In addition, none of the undescended testes had normal spermatogenetic activity. Thus, orchiectomy should be considered in post-pubertal males with unilateral undescended testis that do not need the endocrinological activity of the testis.
