Its called HCG, or human chorionic gonadotrophin. It tricks the body into thinking it is corpus lutem because the embryo actually makes the stuff when pregnant.

I remember that a hormone called hCG is the one tested for to ensure that a woman is pregnant. This is because it is actually made by the embryo after it implants into the mother's endometrium for nourishment. It acts as a replacement for the corpus luteum.
