title: Ultrastructural investigations of undescended testicles.
abstract: In agreement with data in the literature it has been demonstrated that the degree of testis degeneration is directly proportional to the duration of cryptorchism. Though no changes relating tumour or precancerous state have been found, it is suggested--especially in the case of macroscopically intact contralateral testis--that semicastration should be done instead of forced orchidopexy. More examinations are necessary in order to form a final opinion.
