It is a weak androgen with a potency that is approximately 1/7th that of testosterone. In addition, it can be converted to dihydrotestosterone from 3α-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase, bypassing conventional intermediates such as androstenedione and testosterone, and as such, can be considered to be a metabolic intermediate in its own right. Androsterone is also known to be an inhibitory androstane neurosteroid, acting as a positive allosteric modulator of the GABAA receptor, and possesses anticonvulsant effects. The unnatural enantiomer of androsterone is more potent as a positive allosteric modulator of GABAA receptors and as an anticonvulsant than the natural form. Androsterone's 3β-isomer is epiandrosterone, and its 5β-epimer is etiocholanolone. Applications:Androsterone is one of the androgens, which are steroid hormones that affect the masculinization of the fetus and child and that maintain or create masculine traits in adults. Testosterone is the most active and abundant of the androgens. Androsterone was originally isolated from male urine in very small amounts. Many scientists believe it to be a metabolic byproduct of the breakdown of testosterone, and many scientists who study pheromones think it might be active in human relations.
