Human
chorionic gonadotropin (hCG) is a glycoprotein hormone secreted by the
trophoblast cells of the placenta. Its main function is to stimulate the corpus
luteum, which is conducive to the continuous secretion of estrogen and
progesterone to promote the formation of uterine decidua and the growth and
maturation of the placenta.
Once the embryo implants, the trophoblast cells
will begin to secrete hCG, so pregnancy can be judged by the hCG value in the
blood or urine.
