This case study highlights the role of AKR1C2/4 in the alternative androgen pathways. [74] [6] [3] Isolated 17,20-lyase deficiency syndrome due to variants in CYP17A1, cytochrome b 5, and POR may also disrupt the backdoor pathway to DHT, as the 17,20-lyase activity of CYP17A1 is required for both classical and backdoor androgen pathways.

The androgen backdoor pathway (red arrows) roundabout testosterone embedded in within conventional androgen synthesis that lead to 5α-dihydrotestosterone through testosterone [27] [28] [29] CAH is a genetic disorder characterized by impaired production of cortisol in the adrenal glands. [1] [4] Production of cortisol begins at week 8 of fetal ...
removed 11KT since it is not a significant product of the 11-oxy backdoor pathway: 17:21, 18 February 2024: 1,200 × 675 (365 KB) Boghog: Reverted to version as of 11:25, 17 February 2024 (UTC) 14:08, 18 February 2024: 1,200 × 675 (371 KB) Boghog: Added the 11-oxy backdoor pathway is also important in healthy females: 11:25, 17 February 2024: ...
The androgen backdoor pathway (red arrows) roundabout testosterone embedded in within conventional androgen synthesis that lead to 5α-dihydrotestosterone through testosterone. [ 7 ] [ 8 ] [ 9 ] 5α-Pregnan-17α-ol-3,20-dione (17-OH-DHP) is a progestogen , i.e., it binds to the progesterone receptors .

Ignoring this pathway in such instances may lead to diagnostic pitfalls and confusion, [66] when the conventional androgen biosynthetic pathway cannot fully explain the observed consequences. [64] As with the conventional pathway of DHT synthesis, the backdoor pathway similarly requires 5α-reductase. [63]
An androgen (from Greek andr-, the stem of the word meaning ' man ') is any natural or synthetic steroid hormone that regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors. [1] [2] This includes the embryological development of the primary male sex organs, and the development of male ...
11-Ketoandrosterone is a 11-keto form and a metabolite of androsterone.[4]11-Ketoandrosterone belongs to a group of 11-oxyandrogens, i.e. 11-oxygenated (oxygen atom on C11 position forms a ketone group) 19-carbon steroids. 11-oxyandrogens are potent and clinically relevant agonists of the androgen receptors.
