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.
Gonadotropin-releasing hormone (GnRH) is secreted from the hypothalamus by GnRH-expressing neurons. The anterior portion of the pituitary gland produces luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and the gonads produce estrogen and testosterone.he hypothalamicâpituitaryâgonadal axis (also HPG axis) refers to the effects of the hypothalamus, pituitary gland, and gonads as if these individual endocrine glands were a single entity as a whole.
