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.
The placenta will start secreting this hormone immediately after implantation but that doesnât take place until seven to ten days after ovulation. After that the hCG levels will double every 48 to 72 hours but still wonât reach the levels necessary to be detected by a home test until six or seven days after ovulation.
