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.
Cells in the placenta make human chorionic gonadotropin, or hCG. The placenta is the sac that nourishes the egg after itâs fertilized and attaches to the uterine wall. HCG can first be detected in a blood sample about 11 days after conception. Levels of hCG continue to double every 72 hours.
