gonadotropin

gonadotropin /go·nado·tro·pin/ (-tro´pin) any hormone that stimulates the gonads, especially follicle-stimulating hormone and luteinizing hormone.

chorionic gonadotropin , human chorionic gonadotropin (HCG) (hCG) a glycopeptide hormone produced by the fetal placenta syncytiotrophoblasts that maintains the function of the corpus luteum during the first few weeks of pregnancy; the basis for most commonly used pregnancy tests. It is used pharmaceutically to treat certain cases of cryptorchidism and male infertility, to induce ovulation and pregnancy in certain infertile, anovulatory women, and to stimulate oocyte development and maturation in patients using assisted reproductive technologies. See also choriogonadotropin alfa.

human menopausal gonadotropin  (hMG) menotropins.

go·nad·o·tro·pin (g-nd-trpn, -trpn) or go·nad·o·tro·phin (-trfn, -trpn)

n.

A hormone that stimulates the growth and activity of the gonads, especially any of several pituitary hormones that stimulate the function of the ovaries and testes. Also called gonadotropic hormone.

gonadotropin (gōnad´ōtrōp´in),

n (gonadotropic hormone) a gonad-stimulating hormone derived either from the pituitary gland (e.g., follicle-stimulating hormone FSH] and luteinizing hormone [LH], which is also an interstitial cell-stimulating hormone [ICSH]) or from the chorion (e.g., chorionic gonadotropin, which is found in the urine of pregnant women).

gonadotropin, chorionic,

n See hormone, pregnancy.

gonadotropin

any hormone having a stimulating effect on the gonads. Two such hormones are secreted by the anterior pituitary: follicle-stimulating hormone and luteinizing hormone, both of which are active, but with differing effects, in the two sexes.

chorionic gonadotropin

a gonad-stimulating hormone produced by cytotrophoblastic cells of the placenta; used in treatment of underdevelopment of the gonads and to induce ovulation. See also pregnancy tests.

gonadotropin release inhibiting factor

pituitary hormone which inhibits the release of luteinizing hormone or follicle-stimulating hormone.
