title: Relation between the test for gonadal stimulation with HCG and testicular histology in cryptorchism.
abstract: A histological study, by means of bilateral biopsy, on 44 cryptorchid patients (26 of whom are monolateral and 18 bilateral), comparing them with the response obtained for the HCG gonadal stimulation test, is presented. A direct, although not always exact, relation is established between the testicular histology and the testosterone levels after the administration of 4,500 U of HCG.
