Androgen Metabolism Regulation refers to the precise control over the synthesis, conversion, transport, and inactivation of androgens, such as testosterone and dihydrotestosterone, within the human physiology. This regulation is fundamental for maintaining gonadal function, secondary sexual characteristics, and anabolic processes. Dysregulation in this system often presents as clinical sequelae impacting energy, mood, and body composition. Clinical assessment requires evaluating steroid precursors and downstream metabolites.
Origin
The nomenclature derives from ‘Androgen,’ meaning male-producing hormones, and ‘Metabolism Regulation,’ describing the dynamic biochemical processes governing their concentration. Its foundation lies in classical endocrinology concerning the HPG axis feedback. This concept evolved as clinicians recognized the necessity of looking beyond simple total hormone levels. It represents a modern focus on the kinetic fate of steroid hormones within the body.
Mechanism
Regulation occurs via complex enzymatic pathways involving 5-alpha reductase, aromatase, and sulfotransferases in target tissues and the liver. The HPG axis exerts primary control through LH and FSH stimulation of the gonads. Cellular uptake and receptor binding are modulated by sex hormone-binding globulin (SHBG) levels. Effective management targets the enzymes responsible for conversion and clearance to achieve desired physiological concentrations. This interplay ensures hormonal homeostasis across various tissues.
