title: Incidence of serum agglutinating and immobilizing sperm antibodies in infertile couples.
abstract: Blood specimens from 285 consecutive infertile couples were treated for sperm agglutination and for sperm immobilization by the tray slide agglutination test and a microimmobilization test. The immobilization test was positive only when the agglutination test was also positive. Sperm immobilizing activity in association with agglutinating activity was detected in the serum of 7.5% of the husbands and 1.4% of the wives. These sperm immobilizing activity figures may represent the actual incidence of antibodies in patients attending the author's service.
