What is the Origin of Physiological Replacement Therapy?

This clinical term combines Physiological, referring to the normal function of the body, with Replacement Therapy, the medical act of substituting a deficient substance. It is a defining principle in precision and anti-aging endocrinology.

What is the Mechanism of Physiological Replacement Therapy?

The therapy's mechanism focuses on restoring the correct concentration-time profile, often involving the use of bio-identical hormones administered in divided doses or via routes (e.g., transdermal) that avoid first-pass liver metabolism, more closely replicating the continuous or pulsatile secretion of the native gland. This precise dosing ensures optimal receptor saturation and downstream gene regulation without causing negative feedback loops to shut down the body's residual endogenous production.

Physiological Replacement Therapy

Meaning

A clinical approach to hormone therapy that involves administering exogenous hormones in doses and patterns designed to precisely mimic the natural, healthy secretion profile of the endogenous gland, aiming to restore circulating levels to an optimal, pre-decline range. The objective is to provide a replacement that is biologically indistinguishable from the body’s own production, thereby supporting normal cellular function and minimizing the risk of supraphysiological effects or HPA axis suppression. This contrasts with traditional pharmacological dosing.
