Pituitary Somatotrope Response

Meaning

Pituitary Somatotrope Response is the specific secretory output of Growth Hormone (GH) from the somatotrope cells of the anterior pituitary gland in reaction to a stimulatory signal, most notably Growth Hormone-Releasing Hormone (GHRH) or ghrelin. The magnitude, frequency, and characteristic pulsatile pattern of this GH release are critical determinants of systemic IGF-1 production, lean body mass accrual, lipolysis, and overall metabolic function. A diminished or blunted response is a clinical indicator of potential somatotropic axis dysfunction or age-related decline.
