GnRH
|
|
Gonadotrophin Releasing Hormone - the hormone which controls the release of FSH and LH from the pituitary gland
|
|
|
GnRH analogs
|

Synthetic hormones similar to the naturally occurring gonadotropin releasing hormone (GnRH).
|
|
|
Gonadotropin releasing hormone (GnRH)
|
|
Hormone secreted by the hypothalamus that prompts the pituitary gland to release follicle stimulating hormone (FSH) and luteinizing hormone (LH) into the bloodstream.
|
|
|
Gonadotropin releasing hormone agonist (GnRHa)

An agonist for a hormone capable of stimulating the testicles or the ovaries to produce sperm or an egg, respectively.
|
|
|
Gonadotropins
|
|
The category of hormones capable of stimulating the ovary or the testicle to ultimately result in egg or sperm maturation and release. FSH, LH, and hCG are hormones, and all are used at some time during the ovarian stimulation phase of IVF.
