Gonadotropin-releasing hormone (GnRH) is a releasing hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. GnRH is a tropic peptide hormone synthesized and released from GnRH neurons within the hypothalamus. The peptide belongs to gonadotropin-releasing hormone family.
The strongest activator of GnRH neurons is a hormone called kisspeptin. [16] GnRH neurons also integrate information from the body through hormones like neuropeptide Y [17] and adiponectin. [18] These hormones provide the GnRH neurons with information about the body's status to help determine whether reproduction should be prioritized or ...
HPG regulation in males, with the inhibin/activin system playing a similar role on GnRH-producing cells. The hypothalamus is located in the brain and secretes GnRH. [1] GnRH travels down the anterior portion of the pituitary via the hypophyseal portal system and binds to receptors on the secretory cells of the adenohypophysis. [2]
Gonadotropins are glycoprotein hormones secreted by gonadotropic cells of the anterior pituitary of vertebrates. [1] [2] [3] This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the placental/chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG), [3] as well as at least two forms of fish ...
GnRH binds to gonadotropin-releasing hormone receptors (GnRHR), which is a G-protein coupled receptor, and signals the oscillation of calcium that hyperpolarizes gonadotropic cell membranes. [6] This oscillation of calcium ions occurs through the resultant signaling cascade of the GnRH binding to the GnRHR in the plasma membrane of the gonadotroph.
It is the receptor of gonadotropin-releasing hormone (GnRH). Agonist binding to the GnRH receptor activates the Gq/11 family of heterotrimeric G proteins. [1] The GnRHR is expressed on the surface of pituitary gonadotrope cells as well as lymphocytes, breast, ovary, and prostate.

In biology, folliculogenesis is the maturation of the ovarian follicle, a densely packed shell of somatic cells that contains an immature oocyte. Folliculogenesis describes the progression of a number of small primordial follicles into large preovulatory follicles that occurs in part during the menstrual cycle .
