[Comparative study of immunopathogenic ability of autologous and allogeneic spermatozoa in Hartley guinea-pigs (author's transl)].
Autologous or allogeneic spermatozoa in amounts of 10(8), 10(7), 10(6) or 10(5) incorporated in complete Freund's adjuvant were injected into hemiorchidectomized Hartley guinea-pigs. The course of autoimmune aspermatogenic orchi-epididymitis, delayed hypersensitivity and humoral responses to autologous and allogeneic spermatozoa and to spermatozoa autoantigens S, P and T (isolated from a large pool of spermatozoa) were investigated after 1,2,3 or 4 weeks of evolution. Testicular and epididymal lesions and the cellular and humoral responses to autoantigens S and T were nearly identical in autoimmunized and alloimmunized guinea-pigs; but the delayed hypersensitivity responses to whole spermatozoa was more frequent in alloimmunized than in autoimmunized guinea-pigs. This latter result might not be due to the addition of two responses on to autoantigens and one to alloantigens (both present in allogeneic spermatozoa) since the positive responses of the alloimmunized guinea-pigs to autologous spermatozoa compared to allogeneic were found more frequent. From the technical conditions of the experiments, especially due to the use of complete Freund's adjuvant, a helper effect originating in allotypic determinants on allogeneic spermatozoa seems an unlikely explanation. Autoimmunization or alloimmunization in incomplete Freund's adjuvant instead of complete adjuvant provoked a weak response. However, the antibody response to antigen S was significantly more frequent in alloimmunized than in autoimmunized animals; in this case allotypic determinants in autoantigen S responsible for a helper effect might be the cause.
