Human chorionic gonadotropin, a human hormone made by chorionic cells
in the fetal part of the placenta. Human chorionic gonadotropin (hCG) is directed
at the gonads and stimulates them. Hence, the name "gonadotropin."
The presence of hCG is detectable by immunologic means within days of fertilization
and forms the foundation of the common pregnancy tests. The level of hCG tends to
be higher with a female fetus soon after conception.
The level of hCG in maternal serum also enters as one component in the "double"
and the "triple" screening tests used during pregnancy to assign risks of Down syndrome
and other fetal disorders.
