Androgen Receptor Density

Meaning

Androgen receptor density is the quantifiable concentration of androgen receptors within a target cell or tissue, serving as a critical determinant of that tissue’s responsiveness to circulating androgens. This measure dictates the strength of the biological signal initiated by hormones like testosterone and dihydrotestosterone (DHT) at the cellular level. A higher density of these protein structures generally amplifies the resulting physiological effect for a given hormone concentration, profoundly influencing tissue development and function. This parameter is a key factor in understanding the variability of androgen action across different individuals and tissues.
