The effects of testosterone in humans and other vertebrates occur by way of two main mechanisms:by activation of the androgen receptor(directly or as DHT),and by conversion to estradiol and activation of certain estrogen receptors.Free testosterone(T)is transported into the cytoplasm of target tissue cells,where it can bind to the androgen receptor,or can be reduced to 5-dihydrotestosterone(DHT)by the cytoplasmic enzyme 5-reductase.DHT binds to the same androgen receptor even more strongly than T,so that its androgenic potency is about 2.5 times that of T.
