title: Antispermatozoal immunoglobulin G in the sera of subfertile men.
abstract: Sera were obtained from seven men who had not fathered a child and whose semen showed self-agglutination of spermatozoa. These samples of sera produced considerably more immobilization and agglutination of spermatozoa and positive passive hemagglutination tests than did sera from men whose semen showed less than 10% self-agglutination of spermatozoa.
