What is the Origin of Bio-Identical Hormone Administration?

This practice stems from endocrinology's foundational understanding of steroidogenesis and receptor binding specificity. The "bio-identical" nomenclature distinguishes these compounds from synthetic analogues with altered chemical structures. Administration methods are chosen based on pharmacokinetic profiles necessary for tissue-specific effects.

What is the Mechanism of Bio-Identical Hormone Administration?

Administration provides the necessary ligands to bind with target tissue receptors, such as estrogen or androgen receptors, initiating appropriate genomic and non-genomic signaling cascades. The goal is to mimic the natural pulsatile or diurnal secretion patterns to maintain cellular function. This modulation supports processes including bone density maintenance and neurological signaling integrity.

Bio-Identical Hormone Administration

Meaning

The therapeutic application of exogenous hormones that possess an identical molecular structure to those naturally synthesized within the human body. This practice aims to restore physiological hormone levels when endogenous production declines due to aging or pathology. Precision dosing is critical to avoid supra-physiological concentrations.
