Infobox references. 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.
Testosterone is the primary male sex hormone and androgen in males. [ 3 ] In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
5α-Reductase 2 deficiency (5αR2D) is an autosomal recessive condition caused by a mutation in SRD5A2, a gene encoding the enzyme 5α-reductase type 2 (5αR2). The condition is rare, affects only genetic males, and has a broad spectrum. 5αR2 is expressed in specific tissues and catalyzes the transformation of testosterone (T) to 5α ...
The medication is a naturally occurring androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and DHT. [ 2 ][ 6 ] Androstanolone was discovered in 1935 and was introduced for medical use in 1953. [ 2 ][ 7 ][ 8 ][ 9 ] It is used mostly in France and Belgium. [ 2 ...
Schematic diagram of the canonical (left), backdoor (middle), and 11-oxy backdoor (right) pathways of androgen biosynthesis. The androgen backdoor pathway is responsible for the synthesis of physiologically relevant androgens. This process starts with 21-carbon (C21) steroids, also known as pregnanes, and involves a step called "5α- reduction ".
Thus, inhibition results in decreased amounts of DHT. Because of this, slight elevations in testosterone and estradiol levels occur. [36] The 5α-reductase reaction is a rate-limiting step in the testosterone reduction and involves the binding of NADPH to the enzyme followed by the substrate. [4] [37] Substrate + NADPH + H + → 5α-substrate ...
The androgen receptor (AR), also known as NR3C4 (nuclear receptor subfamily 3, group C, member 4), is a type of nuclear receptor [9] that is activated by binding any of the androgenic hormones, including testosterone and dihydrotestosterone, [10] in the cytoplasm and then translocating into the nucleus.
1-Testosterone. 1-Testosterone (abbreviated and nicknamed as 1-Testo, 1-T), also known as δ1-dihydrotestosterone (δ1-DHT), as well as dihydroboldenone, is a synthetic anabolic–androgenic steroid (AAS) and a 5α-reduced derivative of boldenone (Δ1-testosterone). It differs from testosterone by having a 1 (2)- double bond instead of a 4 (5 ...
