Testosterone Cellular Action

Meaning

Testosterone Cellular Action describes the detailed molecular and physiological processes by which the androgen hormone testosterone exerts its effects within target cells, ultimately regulating gene expression and cellular function across various tissues. This action is mediated through two primary pathways: direct binding to the androgen receptor (AR) and conversion to the more potent dihydrotestosterone (DHT) via 5-alpha reductase, which then binds to the AR. Understanding this cellular mechanism is paramount for interpreting the clinical effects of endogenous and exogenous testosterone.
