Human chorionic gonadotropin (HCG) is secreted from the placenta.

  • During pregnancy, the placenta's syncytiotrophoblastic cells largely generate the hormone human chorionic gonadotropin.
  • To keep the pregnancy going, the hormone stimulates the corpus luteum to release progesterone.
  • Along with the pituitary, the liver, and the colon, other organs that produce less HCG include the colon.
  • The two subunits of HCG are HCG alpha and HCG beta .
  • HCG injections are frequently used to promote ovulation in assisted reproductive treatments because they boost progesterone production in the corpus luteum during the early stages of pregnancy.
  • It signals the body to stop menstruating and thickens the uterine lining to support a developing embryo.
  • After fertilization, HCG levels increase and stay elevated for another 10 weeks or more of pregnancy.
