What is the Origin of Androgen Expression Baselines?

The term is rooted in endocrinology and genetics, combining 'androgen expression' which refers to the production and action of male sex hormones in all individuals, and 'baselines', a statistical concept denoting a standard starting point. It acknowledges that what is "normal" for androgen levels is highly personalized and dependent on individual physiology and receptor sensitivity. This lexicon emphasizes a personalized approach to hormonal assessment.

What is the Mechanism of Androgen Expression Baselines?

Androgen expression is regulated by the hypothalamic-pituitary-gonadal (HPG) axis, involving the pulsatile release of GnRH and subsequent production of LH and FSH, which stimulate gonadal androgen synthesis. Baselines are fundamentally influenced by genetic polymorphisms in steroidogenic enzymes and androgen receptor density. The liver and peripheral tissues contribute to the circulating baseline through processes like sex hormone-binding globulin (SHBG) production and local steroid conversion.

Androgen Expression Baselines

Meaning

These are the individualized, genetically and physiologically determined minimal levels of androgen hormones, such as testosterone and DHEA-S, required for optimal function in a healthy state. Establishing these baselines provides a critical reference point for assessing hormonal health, particularly in contexts like muscle mass maintenance, libido, and mood regulation. Fluctuations above or below these intrinsic levels often indicate an underlying endocrine imbalance requiring clinical evaluation.
