What is the Origin of Growth Hormone Secretagogue Response?

The term is rooted in pharmacology and endocrinology, derived from 'secretagogue,' meaning a substance that promotes secretion, and the specific GH pathway. It is a technical assessment used to gauge the potential for therapeutic intervention targeting GH deficiency or decline. The evaluation focuses on the effectiveness of the signal transmission.

What is the Mechanism of Growth Hormone Secretagogue Response?

Secretagogues, such as Sermorelin or Ipamorelin, act by mimicking or potentiating the action of Growth Hormone Releasing Hormone (GHRH) or inhibiting somatostatin, the natural GH inhibitor. This interaction stimulates somatotroph cells in the pituitary to synthesize and release GH into the systemic circulation. Measuring the resulting plasma GH peak confirms the fidelity of this signaling cascade under stimulation.

Growth Hormone Secretagogue Response

Meaning

Growth Hormone Secretagogue Response describes the body’s quantifiable physiological reaction to agents administered to stimulate the release of endogenous Growth Hormone (GH) from the anterior pituitary gland. Evaluating this response is a key metric in assessing the functional integrity of the somatotropic axis. A robust response indicates preserved pituitary sensitivity and hypothalamic signaling capacity.
