What is Gonadotropin-releasing hormone?
'''Gonadotropin-releasing hormone''' ('''GnRH'''), or '''Luteinizing-hormone-releasing hormone''' ('''LHRH'''), is a [[hormone]] [[synthesis|synthesized]] and released from [[neurons]] in the [[hypothalamus]]. GnRH occurs in all [[Vertebrate|vertebrates]]. This single hormone controls all the complex processes which prepare the male and female for successful reproduction. GnRH releases [[follicle-stimulating hormone]] (FSH) and [[luteinizing hormone]] (LH) from the [[pituitary gland|anterior pituitary]]. GnRH activity is very low during childhood, and is activated at [[puberty]] or [[adolescence]]. During the reproductive years, it is critical for successful reproductive function as controlled by feedback loops. However, once a [[pregnancy]] is established, GnRH activity is not required. {{biology-stub}} {{Hormones}} [[Category:Hormones]] [[Category:Proteins]] [[Category:Pregnancy and childbirth]]
