Intra-uterine Injection of Human Chorionic Gonadotrophin (hCG) Before Embryo Transfer

Summary

Chorionic gonadotrophins (hCG) play an important role in implantation. The aim of the study is to evaluate the effect of intrauterine injection of hCG before embryo transfer in IVF/ICSI on the implantation and pregnancy rates. The rational is that intrauterine hCG injection will attract regulatory T cells and improve implantation.
