Abstract:

Recurrent implantation failure (RIF) brings huge economic and psychological burden to infertile couples. After excluding the known maternal-fetal factors, the incidence of unexplained RIF is still high. It is believed that immune factor is one of the potential causes. The success of embryo implantation depends on the local immune tolerance of the mother. Peripheral blood mononuclear cell (PBMC) contain T lymphocytes, B lymphocytes and monocytes. Intrauterine infusion of autologous PBMC can restore the immune balance and improve the endometrial receptivity and the implantation rate. Nowdays, the therapy with autologous PBMC intrauterine infusion has made some progress as a new potential treatment for unexplained RIF. However, the mechanism of therapeutic action is not yet clear, even the therapeutic effect is controversial. In addition, the culture method of PBMC, the number of intrauterine infusion cells, the timing of infusion and the applicable population still need to be further explored.
