Studies on infertility in males.
One hundred and fifteen infertile men were examined for circulating spermagglutinating antibodies by the Kibrick spermagglutination test; thirty-three (28%) were found to have positive agglutination titers--1:32 or more in thirteen samples. This high figure may be explained by the high incidence of genital tract infection and of urinary schistosomiasis in our study group. Of the 33 men who demonstrated autoantibodies in their sera, 21 had microscopic agglutination of more than 10%. There was a positive correlation between the serum autoantibody titer and spermagglutination. Eight cases (6.9%) of sperm-immobilizing antibodies were found.
