Gonadotropin-Releasing Hormone (GnRH)

Meaning

Gonadotropin-Releasing Hormone (GnRH) is a crucial neurohormone synthesized and released by specialized neurons located within the hypothalamus, acting as the primary initiator of the entire reproductive endocrine cascade. This specific decapeptide controls the essential pulsatile secretion of the gonadotropins, Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), from the anterior pituitary gland. The precise pulse frequency and amplitude of GnRH release are critically important for dictating and maintaining normal reproductive function in both males and females.
