Chorionic gonadotropin refers to HCG. A high HCG suggests the possibility of pregnancy and is not harmful, but it is important to rule out the possibility of chorionic chorionic carcinoma and the like. Chorionic gonadotropin is a glycoprotein secreted by the trophoblast cells of the placenta, which promotes the transformation of the corpus luteum to the corpus luteum gestationum after ovulation, produces estrogen and progesterone, and maintains the development of the embryo.HCG is a hormone of the human body, which is harmless to the human body, and a high HCG level suggests the possibility of pregnancy. When HCG is elevated, it is also necessary to rule out pregnancy-related diseases, such as chorionic villus and choriocarcinoma, which can also elevate HCG. If there is an abnormality such as hyperemesis gravidarum or choriocarcinoma, it should be treated as soon as possible.
