Human Chorionic Gonadotropin

Human Chorionic Gonadotropin (hCG) is a hormone produced during pregnancy by the developing embryo and later by the placenta. Its primary role is to support the early stages of pregnancy by maintaining the corpus luteum, which produces hormones like progesterone to sustain the uterine lining. hCG is also what pregnancy tests detect to confirm pregnancy. Additionally, hCG levels can provide information about the health of the pregnancy and are sometimes used in fertility treatments. Its presence and levels are vital indicators in obstetric care.
