Intrauterine Human Chorionic Gonadotrophins (hCG) and Endometrial Treg Cells

Summary

Intrauterine injection of hCG around the time of implantation may increase endometrial Treg cells and improve implantation. It has been demonstrated that regulatory T cells expand during pregnancy. hCG was found to be secreted by the embryo immediately after fertilization and has chemoattractant properties to Treg cells.
