Where is hCG hormone produced?

Human chorionic gonadotropin (hCG) is primarily produced by the placenta during pregnancy. Specifically, it is secreted by the syncytiotrophoblast, a layer of cells that forms part of the outer membrane of the developing embryo. hCG plays a crucial role in maintaining pregnancy by supporting the corpus luteum and stimulating the production of progesterone. Additionally, small amounts of hCG are produced by other tissues, including the pituitary gland.
