Androsterone, or 3α-hydroxy-5α-androstan-17-one, is an endogenous steroid hormone and weak androgen with a potency that is approximately 1/7 that of testosteron. In addition, it can be converted to dihydrotestosterone (DHT) from 3α-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase, bypassing conventional intermediates such as androstenedione and testosteron, ve bunun gibi, can be considered to be a metabolic intermediate in its own right.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 testosteron, and many scientists who study pheromones think it might be active in human relations.
