It is a gonad-stimulating hormone, a placental glycoprotein with luteinizing activity. HCG consists of α (alpha) subunit and β (beta) subunit. The α (alpha) subunit is identical to that of Follicle Stimulating Hormone (FSH), Luteinizing hormone (LH) and Thyroid Stimulating Hormone (TSH), while the β (beta) subunit is unique to HCG.
