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 is an endocrine gland that is only present during pregnancy. In this lesson, you will learn about the hormones it produces, including human chorionic gonadotropin (hCG), progesterone, estrogen, and human placental lactogen (hPL).uring pregnancy, the placenta becomes an extra endocrine organ and produces hormones that help maintain the pregnancy. The first hormone produced is called human chorionic gonadotropin (hCG) . hCG helps maintain the corpus luteum during the early stages of pregnancy.
