Epiandrosterone, or 3β-androsterone, also known as
3β-hydroxy-5α-androstan-17-one or 5α-androstan-3β-ol-17-one, is a
steroid hormone with weak androgenic activity. It is a natural
metabolite of dehydroepiandrosterone via the 5α-reductase enzyme.
It was first isolated in 1931, by Adolf Friedrich Johann Butenandt
and Kurt Tscherning. They distilled over 17,000 litres of male
urine, from which they got 50 milligrams of crystalline
androsterone (most likely mixed isomers), which was sufficient to
find that the chemical formula was very similar to estrone.
Epiandrosterone has been shown to naturally occur in most mammals
including pigs.Epiandrosterone is naturally produced by the enzyme
5α-reductase from the adrenal hormone Epiandrosterone can also be
converted from the natural steroids androstanediol via
17β-hydroxysteroid dehydrogenase or from androstanedione via
1. Epiandrosterone is a naturally occurring steroid synthesized in
the adrenal cortex, gonads, brain, and gastrointestinal tract.
2. It is less active than androsterone and excreted in small
amounts in normal human urine.
3. Epiandrosterone is a metabolite of the most abundant adrenal
androgenic steroid dehydroepiandrosterone in young adult humans,
but is not completely inactive and is considered an effector as
4. Epiandrosterone is a precursor or substrate for cytochrome P450
species and enzymes (EC 22.214.171.124, 25-hydroxycholesterol
7alpha-hydroxylase) that produce 7alpha- and 7beta-hydroxylated
metabolites in the human brain and other organs.
5.These 7-hydroxylated derivatives exert anti-glucocorticoid and
