Adrenal Androgens (DHEA-S, Androstenedione)
DHEA, DHEA-S, and Androstenedione, The Adrenal Contribution to Androgen Status
Evidence grade 3 of 5, Mixed. Read how the Atlas grades evidence.
The written rationale for this grade is still being prepared.
- FDA
- DHEA sold as a supplement in the US; androstenedione is a controlled anabolic agent
- WADA
- Prohibited (S1 Anabolic Agents, DHEA and androstenedione)

What can go wrong
DHEA is an unregulated supplement with variable content and uncertain long-term safety; it can raise estrogens and is prohibited in sport. Androstenedione is a controlled anabolic agent. Neither is a substitute for evaluating low testosterone, and elevated DHEA-S can signal an adrenal disorder warranting workup.
This is something to take to a clinician. The Atlas can tell you what is known about adrenal androgens (dhea-s, androstenedione) in general. It cannot tell you what is happening in your body, and the difference matters most for exactly the symptoms that bring people to this page.
The adrenal cortex produces DHEA, its sulfate DHEA-S, and androstenedione, which can be converted peripherally toward testosterone and estrogens. DHEA-S declines with age and is a marker of adrenal androgen output, fueling 'anti-aging' supplement claims. In men, however, the testes dominate testosterone production, and DHEA supplementation has not shown reliable testosterone or clinical benefit; androstenedione is a banned, ineffective-to-harmful prohormone.
The adrenal gland's androgen contribution, modest in men, and oversold as a testosterone booster.
What people take it for
These are the reasons people give for taking it. They are not effects it has been shown to have.
How it is supposed to work
DHEA and DHEA-S serve as a circulating reservoir that peripheral tissues can convert through androstenedione to testosterone and onward to estradiol, depending on local enzyme expression. In men this peripheral contribution to total testosterone is minor relative to testicular output, so raising DHEA does not reliably raise serum testosterone.
Why the prohormone logic fails in men
The androstenedione craze assumed that flooding the body with a precursor would raise testosterone; controlled studies in men largely showed little testosterone gain and a tendency to raise estrogens instead, which is part of why it was banned. DHEA shares the limitation: its conversion is tissue-regulated, and benefits in healthy men are not established. Adrenal androgens matter more diagnostically (localizing a source of androgen excess) than as a supplement.
Replacement is not the same as a cycle
Physiologic adrenal androgens are a normal part of androgen status. Supraphysiologic prohormone dosing (androstenedione, high-dose DHEA) does not reliably raise testosterone, can elevate estrogens, and carries anabolic-agent risks and sport sanctions.
What it does to fertility
Adrenal androgens at physiologic levels are not a major fertility lever; prohormones with androgenic activity could in principle suppress the axis like other exogenous androgens, though they are simply ineffective for raising testosterone in most men.
What has to be monitored
The bloodwork this needs, and the reason it belongs with a clinician rather than a website.
- DHEA-S (for adrenal evaluation)
- Total/free testosterone and estradiol if androgen-pathway concern
- Adrenal workup if DHEA-S markedly elevated
What people get wrong
Often saidDHEA or 'andro' will raise your testosterone
ActuallyLargely no in men. Conversion is limited and tissue-regulated; androstenedione tends to raise estrogens and is banned, and DHEA shows no reliable testosterone benefit.
Who profits, and who pushes back
Nobody is named here yet, because we have not done that work on this entry. Read that as unfinished. Somebody almost certainly sells this, and somebody almost certainly disputes it. Assume both until we have checked.
Set against the alternatives
Like pregnenolone, adrenal androgens are marketed as testosterone precursors, but the conversion is tissue-regulated and supplementation does not reliably raise male testosterone.
