Gonadotrophin, human chorionic

A hormone produced by the placenta in early pregnancy. Human chorionic gonadotrophin (HCG) stimulates the ovaries to produce oestrogen and progesterone, which are needed for a healthy pregnancy. HCG is excreted in the urine, and its presence in urine is the basis of pregnancy tests on urine samples.
