5α-Reductase inhibitors (5-ARIs), also known as dihydrotestosterone (DHT) blockers, are a class of medications with antiandrogenic effects which are used primarily in the treatment of enlarged prostate and scalp hair loss. They are also sometimes used to treat excess hair growth in women and as a component of hormone therapy for transgender ...
Dihydrotestosterone (DHT, 5α-dihydrotestosterone, 5α-DHT, androstanolone or stanolone) is an endogenous androgen sex steroid and hormone primarily involved in the growth and repair of the prostate and the penis, as well as the production of sebum and body hair composition.
Androstanolone, or stanolone, also known as dihydrotestosterone (DHT) and sold under the brand name Andractim among others, is an androgen and anabolic steroid (AAS) medication and hormone which is used mainly in the treatment of low testosterone levels in men. [2]
5αR2 is expressed in specific tissues and catalyzes the transformation of testosterone (T) to 5α-dihydrotestosterone (DHT). DHT plays a key role in the process of sexual differentiation in the external genitalia and prostate during the development of the male fetus. 5αR2D is a result of impaired 5αR2 activity resulting in decreased DHT levels.
Other symptoms of androgen deficiency are similar in both sexes, such as muscle loss and physical fatigue. [8] The androgens used for androgen replacement in women include testosterone (and esters), prasterone (dehydroepiandrosterone; DHEA) (and the ester prasterone enanthate), methyltestosterone, nandrolone decanoate, and tibolone, among ...
Antiandrogens are drugs that block the effects of androgens like testosterone and dihydrotestosterone (DHT) in the body. [13] They are the most effective pharmacologic treatment for patient-important hirsutism, however they have teratogenic potential, and are therefore not recommended in people who are pregnant or desire pregnancy. Current data ...
Androstanolone enanthate (brand name Anaboleen Depot), also known as stanolone enanthate or dihydrotestosterone heptanoate (DHTH), as well as 5α-androstan-17β-ol-3-one 17β-heptanoate, is a synthetic androgen and anabolic steroid and a dihydrotestosterone ester.
Mesterolone is described as a very poor anabolic agent due to inactivation by 3α-hydroxysteroid dehydrogenase (3α-HSD) in skeletal muscle tissue, similarly to DHT and mestanolone (17α-methyl-DHT). [2] In contrast, testosterone is a very poor substrate for 3α-HSD, and so is not similarly inactivated in skeletal muscle. [2]
