Human chorionic gonadotropin (HCG) is the hormone produced by the embryonic cells and is responsible for maintaining the progesterone and estrogen secretion by the corpus luteum through the first trimester of pregnancy. HCG stimulates the corpus luteum to continue producing progesterone, which is necessary for maintaining the uterine lining and supporting the developing embryo/fetus.
