What is the Meaning of Dihydrotestosterone?

Dihydrotestosterone, abbreviated as DHT, is a potent androgenic steroid hormone derived from the metabolism of testosterone via the enzyme 5-alpha-reductase. This molecule possesses a significantly higher affinity for the androgen receptor compared to its precursor, driving many of the characteristic effects associated with androgen signaling. It plays key roles in male sexual differentiation and maintenance of secondary sexual characteristics.

What is the Origin of Dihydrotestosterone?

The name reflects its chemical structure: 'Di-' indicating two additional hydrogen atoms compared to testosterone, 'hydro-' signifying saturation, and 'testosterone' denoting its steroid class and origin. It is an essential metabolite within the gonadal and adrenal steroidogenesis pathway.

What is the Mechanism of Dihydrotestosterone?

DHT exerts its biological effects by binding with high affinity to the intracellular androgen receptor, facilitating its translocation to the nucleus where it modulates target gene transcription. This action promotes androgenic effects on tissues such as the prostate, hair follicles, and skin, often exhibiting greater biological potency than testosterone itself.
