Controlled estradiol repletion in women revealed three distinct mechanisms of estrogen's GH regulation: enhanced GHRP sensitivity, reduced somatostatin, and modified GH feedback — tripartite estrogen-GH control.
Key findingControlled E2 repletion demonstrated tripartite estrogen regulation of GH secretion: enhanced GH secretagogue (GHRP) pathway sensitivity, reduced soma
What the researchers found
Controlled E2 repletion demonstrated tripartite estrogen regulation of GH secretion: enhanced GH secretagogue (GHRP) pathway sensitivity, reduced somatostatin inhibition, and modified GH autonegative feedback — three independent estrogen-GH control mechanisms confirmed.
