Thyrotropin-releasing hormone (TRH)
Gland: hypothalamus
Function: Stimulates release of prolactin
Corticotropin-releasing hormone (CRH)
Gland: hypothalamus
Function: Stimulates secretion of ACTH
Gonadotropin-releasing hormone (GnRH)
Gland: Hypothalamus

Function: causes release of LH and FSH
Prolactin-releasing factor (PRF)
Gland: hypothalamus

Function: Involved in stimulating release of prolactin
Prolactin release-inhibiting hormone (PIH)
Gland: hypothalamus

Function: Inhibits the release of prolactin, also called dopamine
Growth Hormone (GH)
