Circulating antisperm antibodies in recurrently aborting women.
One hundred seventy-three women with a history of three or more recurrent consecutive abortions were analyzed for circulating antisperm antibodies with a radiolabeled antiglobulin assay (RAA), a modified enzyme-linked immunosorbent assay (ELISA), a tray agglutination test (TAT), and a sperm immobilization test (SIT). No pregnancies were subsequently gestated to term in women who were antisperm antibody-positive unless they were inoculated with their husband's leukocytes as treatment for an immune basis (not related to antisperm antibodies) for their recurrent abortions. In women with an immune basis for their recurrent abortions, immunization with leukocytes from their male partners increased the ability of these women previously aborting their fetuses to carry their fetuses to term, even if they had positive results in the ELISA, TAT, and SIT; women with positive results in the RAA continued to abort subsequent pregnancies, despite leukocyte immunization. Immunization of antisperm antibody-positive women with their partner's leukocytes did not incite or increase the antisperm antibody titer, with any of the assay techniques.
