Dihydrotestosterone (DHT) (Endocrine Sciences)
Also known as: Androstaner-3-one, DHT, Hydroxy-5α
Use
Dihydrotestosterone and dihydrotestosterone/ratio may be used for differential diagnosis of diseases of sexual differentiation (DSD). DHT levels may be inappropriately low compared to testosterone levels in 5a-reductase deficiency. It is recommended by guidelines to measure the ratio of testosterone to DHT.
