BackgroundHuman chorionic gonadotropin is a glycoprotein hormone produced by normal trophoblast cells of the placenta during pregnancy. It is also is produced by trophoblast cells in hydatidiform mole and choriocarcinoma (trophoblast diseases), and in patients with germ cell tumors (testicular choriocarcinoma, placental site tumors and germ cell carcinomas of the ovary) and sometimes in those with other malignancies. Small amount of hCG may also be produced by the pituitary gland. Human CG (hCG) is the hormone associated with the maintenance of pregnancy.
