What is the Origin of DHT?

The abbreviation DHT stands for Dihydrotestosterone, a name that clearly indicates its derivation from testosterone via a reduction process involving two hydrogen atoms. Its distinct physiological importance was fully characterized in the latter half of the 20th century, establishing it as a key, active mediator of androgen action in target tissues. This discovery was central to understanding both normal physiology and conditions like benign prostatic hyperplasia and male pattern baldness.

What is the Mechanism of DHT?

The conversion of testosterone to DHT occurs locally in target tissues like the skin, prostate, and liver, catalyzed by the two isoforms of the 5-alpha reductase enzyme. Once formed, DHT binds to the intracellular androgen receptor with high affinity, forming a complex that translocates into the cell nucleus to regulate gene expression. This genomic action stimulates the development of secondary sexual characteristics and exerts potent anabolic and trophic effects on specific androgen-sensitive tissues.

DHT

Meaning

Dihydrotestosterone, a potent androgen hormone derived primarily from the peripheral metabolism of testosterone through the action of the 5-alpha reductase enzyme in target tissues. DHT is significantly more potent than its precursor at the androgen receptor and plays a vital, non-redundant role in male sexual development, prostate growth, and hair follicle function. Its circulating and tissue-specific levels must be carefully monitored in clinical practice due to its powerful biological effects.
