Abstract
Like most anterior pituitary hormones, growth hormone (GH) is secreted into the bloodstream in a highly episodic manner. In recent years, it has become clear that both the amount of GH and the pattern in which it is secreted are important in determining its biological effects. The pattern of GH release is in turn governed primarily by output of hypothalamic hypophysiotropic peptides, somatostatin (SS) and GH releasing factor (GRF), integrated with input from peripheral endocrine (adrenal, thyroid, gonadal, and pancreatic hormones) and nutritional factors at both hypothalamic and pituitary levels. Furthermore, GH itself and the IGF-I that it generates both can feed back to inhibit production and/or release of GH into peripheral blood.
