Hormonal Regulation of Hormone Release. Hormonal regulation of hormone release involves a hormone binding to its receptor on an endocrine cell to regulate hormonal secretion. A hormone that stimulates hormone secretion is called a tropic hormone. Tropic hormones may also stimulate proliferation of endocrine cells.or polar hormones, tropic hormones stimulate endocrine secretion by stimulating cell secretion; that is, exocytosis. An example is the regulation of growth hormone (GH) secretion by the tropic hormone growth hormone releasing hormone (GHRH) . GHRH is a hypophysiotropic hormone.
