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.
Human chorionic gonadotropin (hCG) produced by the cells of the fertilised egg (blastocyst) builds up rapidly in your body. It doubles every 2 to 3 days in the first few weeks of pregnancy reaching a peak level by 8-12 weeks. Pregnancy tests detect this hormone in urine and blood.
