What does a DHEA-S test tell you?
It tells you how much DHEA-S your adrenal glands are making. MedlinePlus explains that DHEA-S is made mostly in the adrenal glands, which sit above the kidneys, with smaller amounts from the testes. It is a weak androgen and a building block the body can use to make testosterone and estrogen.
DHEA-S levels peak around puberty and early adulthood, then fall with age. That built-in decline is the single most important thing to know when reading your result, because the right comparison is with men your age, not with a 25-year-old.
What are typical DHEA-S ranges for men?
Ranges are set by age because the hormone falls so predictably. The MedlinePlus encyclopedia lists these typical ranges for males, and notes that ranges vary slightly among labs:
| Age | Typical range (µg/dL) | Typical range (µmol/L) |
|---|---|---|
| 18 to 29 | 110 to 510 | 3.0 to 14.0 |
| 30 to 39 | 110 to 370 | 3.0 to 10.0 |
| 40 to 49 | 45 to 345 | 1.2 to 9.4 |
| 50 to 59 | 25 to 240 | 0.7 to 6.5 |
| 60 and older | Less than 204 | Less than 5.5 |
Look at how wide each band is. A 55-year-old at 60 µg/dL and one at 220 µg/dL are both in range. The number becomes interesting mainly when it sits well outside the band for your age or does not fit the rest of your labs.
What does an unusually high result suggest?
A high DHEA-S points to the adrenal glands. MedlinePlus lists congenital adrenal hyperplasia, an inherited enzyme disorder, and adrenal tumors, which can be benign or cancerous, as causes of high levels. Men often have no symptoms from high DHEA-S itself.
There is also a simpler explanation to rule out first: a DHEA supplement. The supplement raises the blood level directly, which is why MedlinePlus asks you to report any DHEA product before the test. A very high value without a supplement explanation is worth a closer look, often with imaging or other adrenal hormones.
What does an unusually low result suggest?
A low DHEA-S below the range for your age can reflect adrenal insufficiency, including Addison disease, a pituitary gland that is not making enough of its hormones (hypopituitarism), or recent glucocorticoid medicines such as prednisone, according to MedlinePlus. Adrenal insufficiency often brings other symptoms, such as unexplained weight loss, nausea, dizziness, salt craving and dehydration.
A low DHEA-S that simply tracks age is not a disease. Our page on adrenal fatigue in men looks at how tiredness and the adrenal glands do and do not connect, and the morning cortisol test is the usual next step when true adrenal insufficiency is a concern.
Why are DHEA supplements not a testosterone substitute?
Because they do not fix the problem behind most low testosterone in men, and the evidence for them is weak. In men, the testes make most testosterone in response to signals from the pituitary. When those signals or the testes falter, raising a weak adrenal precursor does not restore normal levels in a controlled, monitored way.
MedlinePlus states that there is no reliable evidence supporting the anti-aging claims made for DHEA supplements and warns that they may cause serious side effects. DHEA is sold as a dietary supplement, so it does not go through FDA approval for safety or effectiveness before it reaches shelves. It is also on the World Anti-Doping Agency prohibited list. Our page on whether testosterone boosters work covers the wider supplement aisle.
If your symptoms point to low testosterone, the more useful path is two early-morning testosterone tests, LH and FSH to locate the cause, and a real discussion of treatment options. Our comparison of TRT and testosterone boosters lays out the difference.
How Ultimate Male uses DHEA-S
DHEA-S is not one of the four tests in the TRT pre-screening panel. Whether it is worth measuring depends on your symptoms, your other hormone results and whether you already take DHEA, so ask on the free 10-minute call whether the panel you are considering includes it or whether it makes sense to add.
At the consultation in San Gabriel or Downey, a PA-C or MD reads DHEA-S against your age band and your testosterone, cortisol and pituitary picture, and tells you plainly whether a supplement you are taking is helping, irrelevant or skewing your labs. Our page on hormone imbalance in men shows how the pieces fit, and our preventative blood testing page lists every panel.
