Introduction：
Human chorionic gonadotropin (HCG) is a chemical created by trophoblast tissue, tissue typically found in early embryos and which will eventually be part of the placenta. Measuring hCG levels can be helpful in identifying a normal pregnancy, pathologic pregnancy, and can also be useful following an aborted pregnancy. There is also a benefit in measuring hCG in a variety of cancers including choriocarcinoma and extra-uterine malignancies.
What is HCG used for?
Female infertility
Low testosterone in males (hypogonadism)
Prepubertal cryptorchidism (a condition in boys who haven’t reached puberty where the testes haven’t moved into the scrotum)
