Where there were no differences between the degree of contribution of HLA antigen In couples with recurrent spontaneous abortion and control groups, longitudinal study has shown before and after the pregnancy completed pairs frequently suffer from abortion did not find differences in the extent of the contribution of HLA Between couples who succeeded their pregnancy and later among those lost as well as the inability to prove an increase in the production of the immunological factors Algalqh against HLAantigen Jenin (parental) after pregnancy in each of these women and the control group (Caudle et al.,1983) .

It is through injecting women with recurrent spontaneous abortion unknown reasons, the chance of successful pregnancy have been only 50%. (Stites et al., 1997).
