Dihydrotestosterone (DHT, 5α-dihydrotestosterone, 5α-DHT, androstanolone or stanolone) is an endogenous androgen sex steroid and hormone. The enzyme 5α-reductase catalyzes the formation of DHT from testosterone in certain tissues including the prostate gland, seminal vesicles, epididymides, skin, … See more DHT is biologically important for sexual differentiation of the male genitalia during embryogenesis, maturation of the penis and scrotum at puberty, growth of facial, body, and pubic hair, and development and maintenance of … See more DHT is a potent agonist of the AR, and is in fact the most potent known endogenous ligand of the receptor. It has an affinity (Kd) of 0.25 to 0.5 nM … See more DHT is available in pharmaceutical formulations for medical use as an androgen or anabolic–androgenic steroid (AAS). It is used mainly in the treatment of male hypogonadism. When used as a medication, dihydrotestosterone is referred to as androstanolone ( See more Biosynthesis DHT is synthesized irreversibly from testosterone by the enzyme 5α-reductase.
