Brief Summary

The goal of this clinical trial is to test the effect of modulated specialised immune cells isolated from the patients' own blood when administered to the uterus before embryo transfer on the IVF outcome (implantation, pregnancy and live birth rates). To achieve this, blood will be obtained from eligible participants. Target cells will be isolated and incubated with the tested modulator for 24h, and returned to the uterine cavity 1 day prior to embryo transfer. Researchers will compare the reproductive outcome of the tested intervention to that of a control group who will not receive the investigated cell treatment prior to embryo transfer.
