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. [ 7 ] [ 8 ] [ 9 ] 5α-Pregnan-17α-ol-3,20-dione (17-OH-DHP) is a progestogen , i.e., it binds to the progesterone receptors .
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 ...

Therefore, androstanediol can be used a marker of the backdoor pathway of DHT synthesis. [11] Spectrometric studies identify androsterone as the main backdoor androgen in the human male fetus. Circulating levels are sex dependent, DHT being essentially absent in the female, in which titres of backdoor intermediates also are very low. [12]
Androgens are synthesized in the testes, the ovaries, and the adrenal glands. Androgens increase in both males and females during puberty. [3] The major androgen in males is testosterone. [4] Dihydrotestosterone (DHT) and androstenedione are of equal importance in male development. [4] DHT in utero causes differentiation of the penis, scrotum ...
The activity of this enzyme towards 3α-diol is important not only in the conventional pathways of androgen biosynthesis, but also in the androgen backdoor patthway. [ 21 ] [ 22 ] [ 23 ] [ 7 ] An important emzyme activity in humans is the transformation of the one of the most potent natural androgens, 5α-dihydrotestosterone into 3α-diol, a ...
