  The important role of HCG

  The main function of HCG is to stimulate the conversion of corpus luteum from the menstrual corpus luteum to the gestational corpus luteum, promote the continuous secretion of estrogen and progestin, maintain the endometrial morphology, promote the formation of the uterine decidua, and make the placenta grow and mature, which is essential for the maintenance of pregnancy.

  At the same time, HCG can also inhibit the stimulating effect of lectin on lymphocytes, and human chorionic gonadotropin can be adsorbed on the surface of trophoblast cells, so as to prevent embryonic trophoblast cells from being attacked by maternal lymphocytes.
