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.
hCG is important because it is the hormone that pregnancy tests detect to determine if you are in fact pregnant. The average non-pregnant woman has less than 5mlU/ml of hCG present. However, in the first few weeks after implantation happens the amount of hCG that is secreted doubles every 48-72 hours.
