Summary
Human chorionic gonadotropin (hCG) is primarily produced in human trophoblasts and placentas. It comprises α- and β-subunits, the former of which is a common form of gonadotropins, and the latter is typical of hCG. hCG has three main functions: corpus luteum maintenance, testicular stimulation, and maternal thyroid stimulation. hCG is used to determine pregnancy, with commercial urine hCG pregnancy kits widely used. In addition, hCG is used to judge normal pregnancy. One typical case of abnormal pregnancy is ectopic pregnancy, and the other is gestational trophoblastic disease. The β-subunit is useful for determining both normal pregnancy and gestational trophoblastic disease.
