Aromatase and 5α-Reductase Inhibition during an Exogenous Testosterone Clamp Unveils Selective Sex Steroid Modulation of Somatostatin and Growth Hormone Secretagogue Actions in Healthy Older Men

Abstract

The present outcomes suggest a tetrapartite model of GH regulation in men, in which systemic concentrations of Te, DHT, and E(2) along with abdominal visceral fat determine the selective actions of GH secretagogues and SS.
