a hormone that stimulates the rate of secretion of hypophysial hormones; for example, a releasing factor; hypothalamic (regulatory) factor.

hypophysiotropic hormone

A hormone produced by the endocrine cells in the hypothalamus, released to the corresponding capillary bed—the median eminence—and transported directly to the anterior pituitary via the hypophyseal portal vessels. Hypophysiotropic hormones’ sole role are to regulate hormone release by the adenohypophysis.

Our results are similar to those of other studies which indicated that galanin is a hypophysiotropic hormone that elicits GH secretion (Bauer et al., 1986; Giustina et al., 1993) and enhances the GH response to GHRH in NE-fed nonruminants (Davis et al., 1987).
