ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of allogeneic leukocyte immunization combined with in vitro fertilization-embryo transfer (IVF-ET) for treatment of infertility induced by habitual abortion.</p><p><b>METHODS</b>Allogeneic leukocyte immunization was performed in 9 patients with infertility induced by habitual abortion, with another 9 patients undergoing IVF-ET without habitual abortion as the control group. All the patients were treated with long GnRH-a protocols. The infertility patients with recurrent spontaneous abortion history were immunized with lymphocytes from the husband for before IVF-ET and after clinical pregnancy.</p><p><b>RESULTS</b>The fertilization rates of the immunotherapy group and control group were 81.3% and 82.2%, respectively, showing no significant difference (P>0.05). Five patients in each group had clinical pregnancy, and a twin pregnancy occurred in the control group. The embryo implantation rates were also comparable between the two groups (22.7% vs 28.6%, P>0.05). All the fetuses resulted from IVF-ET developed normally and were healthily delivered.</p><p><b>CONCLUSION</b>Allogeneic leukocyte immunotherapy along with IVF-ET is effective for treatment of infertility resulting from recurrent spontaneous abortion.</p>
