- 01DHEA-S tells you where androgen comes from; testosterone and the pace of symptoms tell you how worried to be
DHEA-S (dehydroepiandrosterone sulfate) is made almost entirely by the adrenal glands, so a high DHEA-S says the extra androgen is adrenal in origin. On its own it cannot separate a tumour from a harmless cause. In a 1994 NEJM study of hirsute women, all 14 women with adrenal tumours had a raised testosterone or DHEA-S, but so did 36 of the 73 women without a tumour 5. The authors concluded that "an adrenal tumor is unlikely if the patient has normal basal serum concentrations of testosterone and dehydroepiandrosterone sulfate" 5. Read a high DHEA-S for its source, then let testosterone and the speed of symptoms decide how urgent it is 2.
DHEA-S is the stored form of DHEA, a hormone the adrenal glands make and the body turns into testosterone and estrogen where it needs them. Because almost all of it comes from the adrenals, a high result means the adrenal share of your androgens is larger than usual for your age and sex. People searching for "high DHEA levels" are nearly always holding a DHEA-S result, because the sulfate form is the one labs measure. Our DHEA-S guide covers what the marker is and how it is tested.
Start with the marker itself
What counts as high: DHEA-S levels by age and sex
There is no single cutoff for DHEA-S. Levels peak in the 20s and fall steadily, so a 65-year-old typically runs at a fraction of a 25-year-old's level, and men run higher than women at every age 4. The ranges below are the typical values MedlinePlus gives; your report prints its own range, and that is the one to use. To convert, multiply ug/dL by 0.0271 to get umol/L.
| Age | Women, ug/dL | Women, umol/L | Men, ug/dL | Men, umol/L |
|---|---|---|---|---|
| 18 to 29 | 45 to 320 | 1.2 to 8.7 | 110 to 510 | 3.0 to 14.0 |
| 30 to 39 | 40 to 325 | 1.1 to 8.8 | 110 to 370 | 3.0 to 10.0 |
| 40 to 49 | 25 to 220 | 0.7 to 6.0 | 45 to 345 | 1.2 to 9.4 |
| 50 to 59 | 15 to 170 | 0.4 to 4.6 | 25 to 240 | 0.7 to 6.5 |
| 60 and over | under 145 | under 3.9 | under 204 | under 5.5 |
Example: a DHEA-S of 300 ug/dL in a woman aged 55ug/dL
No guideline grades a high DHEA-S into mild, moderate and severe bands, so the table below sorts results by whether they are above your age range and whether red flags are present. Older teaching treated a DHEA-S above about 700 ug/dL (about 19 umol/L) as a sign of an adrenal tumour. A level that high calls for further tests, but the number alone does not settle it: in the 1994 study, a dexamethasone suppression test, not the size of the DHEA-S, separated the tumours from the harmless causes 5.
| Band | What it usually means | Usual next step |
|---|---|---|
| Within your age and sex range | Normal adrenal androgen output for age 4 | Nothing for DHEA-S; if you have symptoms, testosterone is the next number to read |
| Above the range, no red flags | Most often a supplement, a wrong age range or PCOS; less often non-classic CAH (an inherited adrenal enzyme condition), high prolactin or Cushing's syndrome 2 3 | List every supplement for your doctor (pausing one that is not prescribed is a common first step), repeat at the same lab, and read testosterone and SHBG (the protein that holds testosterone inactive); a 17-hydroxyprogesterone test if non-classic CAH is possible 2 |
| Above the range with red flags | Possible androgen-secreting tumour 2 5 | See the red flags below |
When it is urgent
No lab publishes a critical value for DHEA-S, and no DHEA-S number on its own is an emergency. The pattern that matters is speed. The Endocrine Society hirsutism guideline singles out rapid onset or progression of symptoms, and signs of virilisation, as the trigger to look for an androgen-secreting tumour 2.
Is it really high?
Before reading a single high DHEA-S as disease, rule out the reasons that raise the number without any adrenal problem. They explain most isolated mild highs.
- The wrong age range: a result in your early 20s read against an all-adult or older range looks high when it is normal for your age 4.
- A DHEA supplement, including DHEA hidden in "adrenal support", "anti-aging" and testosterone-booster blends: 50 mg a day lifted DHEA-S into the young-adult range within 2 weeks in adults aged 40 to 70 7.
- Ashwagandha: in a 16-week crossover trial in overweight men aged 40 to 70, 8 weeks of ashwagandha raised saliva DHEA-S by about 18% more than placebo 6. It has not been tested in women.
- High-dose biotin, common in hair and nail products, can make some DHEA-S tests read falsely high 8. Our guide to preparing for a blood test covers how long to pause it.
- A change of lab: different labs use different test methods that give different numbers, so compare results from the same lab.
- Time of day matters little: DHEA-S barely moves through the day, unlike DHEA and cortisol, so a midday draw is not the explanation.
No symptoms and only a mild high? This is a routine appointment with your GP or primary care doctor, not an urgent one. Take your result, your age and a list of every supplement you take, and ask whether testosterone, SHBG and a repeat DHEA-S are worth doing.
Causes
Common
| Cause | How it raises DHEA-S | The clue | What confirms it |
|---|---|---|---|
| DHEA supplement | Supplies DHEA, which the body converts to DHEA-S 7 | Taking a hormone, booster or "anti-aging" blend | A repeat in range after stopping |
| Ashwagandha supplement | Raised DHEA-S in a trial in men; mechanism unclear 6 | Taking an adaptogen or "hormone balance" blend | A repeat in range after stopping |
| Young age read against an adult range | Normal peak output in the 20s 4 | Age under 30, no symptoms | Age-matched range on the report |
| PCOS | Adrenal androgen excess in about 20 to 30% of women with PCOS 3 | Irregular periods, acne or excess hair, often weight gain | Total testosterone, SHBG, ultrasound; testosterone is the first-line test 1 |
Less common
| Cause | How it raises DHEA-S | The clue | What confirms it |
|---|---|---|---|
| Non-classic congenital adrenal hyperplasia (CAH, an inherited enzyme shortfall in cortisol production) | Blocked cortisol pathway diverts precursors into androgens 2 | Excess hair or acne from puberty, family history, some ancestries more affected | Early-morning 17-hydroxyprogesterone, in the first week after your period starts if you have periods 2 |
| High prolactin | Listed in the guideline's differential for androgen excess 2 | Milky nipple discharge, missed periods, headaches | Prolactin |
| ACTH-dependent Cushing's syndrome | Excess ACTH (the pituitary signal that tells the adrenals to work) drives cortisol and adrenal androgens together | Rounded face, purple stretch marks, easy bruising, high blood pressure | Cortisol tests ordered by a doctor; see Cushing's syndrome and high morning cortisol. Cortisol-secreting adrenal tumours do the opposite and usually give a low DHEA-S 10 |
Must not miss
| Cause | How it raises DHEA-S | The clue | What confirms it |
|---|---|---|---|
| Androgen-secreting adrenal tumour (adenoma or carcinoma) | The tumour makes androgens on its own 5 | Red flag: male-pattern signs developing over months; testosterone very high 2 | Total testosterone first, then a dexamethasone suppression test and adrenal imaging as a specialist decides 2 5 |
The markers that sort the causes
Symptoms of high DHEA-S in women
A DHEA-S slightly above the range often causes nothing at all, and many people find it on a routine panel. When symptoms appear, in women they are the signs of androgen excess: acne, extra hair on the face, chest or abdomen (hirsutism), thinning scalp hair, and irregular or missed periods 2. Irregular ovulation is what can make conception harder, which is why fertility depends on the cause, usually PCOS, rather than on the DHEA-S number 1. See hair loss and irregular periods for the wider causes of each.
High DHEA-S in men
Men rarely notice a high DHEA-S, because the testes make far more testosterone than the adrenal contribution adds. In a man, a high result most often traces back to a supplement, young age or the assay; new acne or breast tissue growth alongside a high DHEA-S is worth raising with a doctor. In older men the worry runs the other way: in a study of elderly Swedish men, it was low DHEA-S that went with higher death rates 9, so a high-normal result is not something to chase down. Anxiety, insomnia and body odour are often listed online as high DHEA-S symptoms, but no study links them to DHEA-S itself.
Read it with your other markers
DHEA-S on its own says little about how much androgen reaches your tissues. Testosterone and SHBG decide that, so read the three together. The female hormone panel and male hormone panel guides cover the full set, and hormonal imbalance covers the wider picture.
| Pattern | What it suggests | Read next |
|---|---|---|
| High DHEA-S, normal testosterone, no symptoms | Supplement, young age or assay quirk | Repeat at the same lab |
| High DHEA-S, high testosterone, irregular periods | PCOS with adrenal androgen excess 1 3 | PCOS |
| Normal DHEA-S, high testosterone | Androgen more likely from the ovaries | High testosterone |
| High DHEA-S, low SHBG | More free testosterone, so more symptoms at the same totals | Free testosterone calculator |
| High DHEA-S, high early-morning 17-OHP (17-hydroxyprogesterone) | Possible non-classic CAH 2 | 17-hydroxyprogesterone |
| High DHEA-S, very high testosterone, fast symptoms | Rule out an adrenal tumour 2 5 | See the red flags above |

What can bring it down
The biggest lever is removing what raised the number. After that, treatment targets the cause and the symptoms, and those decisions sit with a doctor.
| Change | Effect measured in humans | Evidence | Source |
|---|---|---|---|
| Stopping a DHEA supplement you started yourself | Removes the direct source; DHEA-S would be expected to fall back toward baseline (the rise on 50 mg a day came within 2 weeks) | Expected from how it works; a stopping trial was not run | 7 |
| Stopping ashwagandha | Removes the source of a rise of about 18% versus placebo seen in one trial in men; the fall after stopping was not measured | RCT (rise only) | 6 |
| Weight loss and lifestyle change in PCOS | Recommended as the foundation of PCOS care; improves androgen excess overall, DHEA-S effect not separately measured | Guideline | 1 |
| Combined oral contraceptive for hirsutism (prescribed) | First-line drug for hirsutism; an antiandrogen is added if the response after 6 months is not enough | Guideline | 2 |
| Treating the cause (CAH, prolactin, Cushing's, tumour) | DHEA-S follows the cause | Guideline | 2 |
