Besides the pathological anti-sperm humoral immunity, pathological anti-sperm cell-mediated immunity is considered as a crucial facet of the disturbances of human reproduction (male and female infertility, recurrent abortions, endometriosis, late EPH gestosis, fetal hypotrophy). A precise and objective method is designed, based on a one-step agarose Leukocyte Migration Inhibition Factor assay. The migration areas are evaluated by a computer-assisted image analysis system. Optimal concentrations of leukocytes and sperm, as well as technical conditions are described. The Radius Migration Indexes and Area Migration Indexes are computed and expressed as a Migration Index percentage for each patient or control. Preliminary clinical results indicate a highly significant association between leukocyte migration inhibition and cases of "immunopathological" infertility and repeated fetal loss.
