[The chorionic gonadotropin hormone: possible cause of seminoma?].

Two cases of seminoma that appeared in young males who had received high dosages of Chorionic Gonadotrophin Hormone (HCG) as treatment for secondary sterility are presented. The authors suggest that this treatment has an etiological or at least permissible role in the development of these tumors. Careful examination with testicular biopsy is recommended on all males receiving hormone treatment for oligospermia, and follow-up should continue after cessation of the treatment.
