A very low incidence of antibody reactive with solubilised trophoblast membrane was detected, and no significant antibody to either hCG or SP1 could be detected. Infertile states represented within this serum bank appear unlikely to involve adverse immune reactions to trophoblast. © 1985.Mahidol UniversityImmunology and MicrobiologyMedicineArticleSCOPUS10.1016/0165-0378(85)90009-9
