The alloimmunization of the partners lymphocytes is accompanied by an increase in the proliferative response in all groups of women regardless of HLA sharing. However, woman with a high sharing of HLA antigens have a lower level of cell proliferation than woman with no sharing of HLA antigens.</p>infertilityHLA sharingproliferative responsemixed lymphocyte cultureбесплодиеантигены гистосовместимостипролиферативный ответсмешанная культура лимфоцитов[1.
