5β-Androstanediol, also known as 5β-androstane-3α,17β-diol, is a natural steroid hormone found in the human body. It is a metabolite of the more potent androgenic hormone dihydrotestosterone (DHT), which itself is derived from testosterone.

Unlike its counterpart, 5α-androstanediol, which has weak androgenic properties, 5β-androstanediol is typically considered inactive in terms of androgenic effects. It is present in both males and females, although in relatively small quantities, and its specific physiological functions are not well understood.

While research into the roles and effects of 5β-androstanediol is ongoing, it appears to have minimal influence on sexual development, behavior, or other hormonal processes compared to more potent androgens like DHT or testosterone. Its significance in the endocrine system and its precise functions remain areas of scientific investigation.
