Human chorionic gonadotropin (hCG, or human chorionic gonadotrophin) is a placental hormone initially secreted by cells (syncitiotrophoblasts) from the implanting conceptus during week 2, supporting the ovarian corpus luteum, which in turn supports the endometrial lining and therefore maintains pregnancy.
It is the hormone that is produced by the placenta after the embryo implants in early pregnancy. HCG is also the hormone that is detected by at home pregnancy tests in early pregnancy. For the first few weeks of pregnancy, HCG levels double every two or three days until finally leveling off.Later in the pregnancy, after the HCG levels begin to level out, they will slowly begin to drop again.CG is also the hormone that is detected by at home pregnancy tests in early pregnancy.
