[2][160] 3β-Androstanediol and 3β-etiocholanediol can also be formed in this pathway when 5α-DHT and 5β-DHT are acted upon by 3β-HSD instead of 3α-HSD, respectively, and they can then be transformed into epiandrosterone and epietiocholanolone, respectively. The albumin-bound testosterone combined with free testosterone makes up for approximately 35% of total testosterone levels. Effects before birth are divided into two categories, classified in relation to the stages of development. [44] Some research has also indicated that if testosterone is eliminated in an adult male human or other adult male primate's system, its sexual motivation decreases, but there is no corresponding decrease in ability to engage in sexual activity (mounting, ejaculating, etc.).[44].

[170][171] As much as 90% of testosterone is converted into 5α-DHT in so-called androgenic tissues with high 5α-reductase expression,[161] and due to the several-fold greater potency of 5α-DHT as an AR agonist relative to testosterone,[172] it has been estimated that the effects of testosterone are potentiated 2- to 3-fold in such tissues.
