Carcinoma-in-situ germ cells were demonstrated in testicular biopsies from 9 of 826 patients (1.1%) from a selected group of Danish infertile men. A similar observation was noted in testicular biopsies from 9 Swiss patients (representing 0.55% of the

Based on evidence from morphological and histochemical studies and from clinical experience, the following hypotheses are proposed: carcinoma-in-situ (CIS) germ cells are malignant gonocytes; these CIS gonocytes have some capacity to regress into mor
