Explanation:
Detailed explanation-1: -Human chorionic gonadotropin is a hormone produced primarily by syncytiotrophoblastic cells of the placenta during pregnancy.
Detailed explanation-2: -This hormone is secreted by the placenta in pregnant women. Human chorionic gonadotrophin (hCG) is a hormone produced by the cells that surround the growing human embryo that go on to form the placenta (called trophoblasts).
Detailed explanation-3: -hCG is secreted by the syncytiotrophoblast which originates from fused and differentiated cytotrophoblast cells [3, 4]. For a long time, the main known role of hCG was the promotion of progesterone secretion by the corpus luteum in early pregnancy, acting via the hCG/LH (luteinizing hormone) receptor.
