Gonadotropin-releasing hormone (GnRH) Written By: Gonadotropin-releasing hormone (GnRH), also known as luteinizing hormone-releasing hormone, a neurohormone consisting of 10 amino acids that is produced in the arcuate nuclei of the hypothalamus. GnRH stimulates the synthesis and secretion of the two gonadotropinsâluteinizing hormone (LH) and follicle-stimulating hormone (FSH)âby the anterior pituitary gland.
Puberty's trigger lies in a small part of the brain called the hypothalamus, a gland that secretes gonadotropin-releasing hormone (GnRH). GnRH stimulates the pituitary gland, a pea-sized organ connected to the bottom of the hypothalamus, to emit two hormones: luteinizing (pronounced LOO-tee-uh-nize-ing) hormone (LH) and follicle-stimulating hormone (FSH).
