5a,3a–androstanediol is a neuroactive steroid that enhances dopamine activity, important for mood elevation.
3a-Androstanediol (often abbreviated as 3a-diol), also known as 5a-androstane-3a,17b-diol, is an endogenous inhibitory androstane neurosteroid and a weak androgen, and a major metabolite of dihydrotestosterone (DHT). As a neurosteroid, it acts as a potent positive allosteric modulator of the GABAA receptor, and has been found to have rewarding, anxiolytic, pro-sexual, and anticonvulsant effects. Relative to its isomer 3b-androstanediol, which is a potent estrogen, 3a-androstanediol has substantially lower, though still significant affinity for the estrogen receptors.
