title: [Y-chromosome polysomy and expression of the H-Y antigen].
abstract: The sex-differentiation H-Y antigen was studied in 5 males subjects with Y-chromosome polysomy. All had gonadal deficiency and significant decrease of H-Y antigen as compared with 77 normal 46, XY male controls. Men with additional Y-gonosomes may be hypogonadic or, more often, fertile, as was probably the case with the 3 patients with very high H-Y antigen titers previously described by other research workers. The phenotypic polymorphism of these subjects therefore seems to be parallel with their H-Y antigen polymorphism and there may be, in our 5 subjects, a relationship between abnormal spermatogenesis and H-Y antigen deficiency.
