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.
Pregnancy Hormones. A pregnancy hormone known as hCG is in your blood from the time of implantation. This is the hormone detected in a pregnancy test. Usually it takes 3 to 4 weeks from the first day of your last period for the levels of hCG to be high enough to be found by the tests.
