What is the Meaning of HCG?

Human Chorionic Gonadotropin is a glycoprotein hormone primarily produced by the syncytiotrophoblast of the placenta during pregnancy, though small amounts can be produced by pituitary tumors. Clinically, it is essential for maintaining the corpus luteum's progesterone production in early gestation. Measurement of serum or urine HCG is the standard diagnostic test for pregnancy.

What is the Origin of HCG?

The name directly references its human origin and its gonadotropin function, as it mimics the action of Luteinizing Hormone (LH) on the ovarian follicles. Its detection was historically key in pregnancy diagnosis assays.

What is the Mechanism of HCG?

HCG exerts its primary effect by binding to the LH/Choriogonadotropin receptor on ovarian cells, activating the cAMP signaling cascade. This activation sustains the production of progesterone, which is vital for endometrial maintenance and supporting the early pregnancy environment. In non-pregnant contexts, exogenous HCG is sometimes used to stimulate testicular function or trigger ovulation.
