HCG ( Human Chorionic Gonadotrophin )  is a glycoprotein hormone produced during pregnancy that is Made by the developing embryo after conception and later by the Syncytiotrophoblast (part of the
Placenta). Some cancerous tumors produce this hormone; therefore, elevated levels measured when the patient is not Pregnant can lead to a cancer diagnosis. however, it is not known whether this Production is a contributing cause or an effect of tumorigenesis. The pituitary Analog of HCG, known as luteinizing hormone (LH), is produced in the pituitary Gland of males and females of all ages.
