Prevalence of intratubular germ cell neoplasia in cryptorchid testes of infertile men.

Background: Cryptorchidism is a common malformation in neonates; surgery or medical treatments are applied during childhood. Untreated cryptorchid testes are in the risk of intratubular germ cell neoplasia (IGCN) and consequently invasive testicular tumors which could be shown by immunohistochemistry staining for placental like acid phosphatase (PLAP) marker.

Objective: We designed this study to know the prevalence of IGCN in untreated cryptorchid testes of infertile men, in our infertility center as a refferal center.
