Low DHEA or DHEA-S levels in men are usually treated by finding and managing the underlying cause, not by taking a DHEA supplement simply because the result is low. Possible causes include normal aging, adrenal insufficiency, pituitary disease, glucocorticoid medication and other health conditions.

Low DHEA Treatment at a Glance
| Situation | Usual medical approach |
|---|---|
| Low DHEA-S with no significant symptoms | Compare the result with the laboratory's age-specific range and investigate further only when the clinical picture calls for it |
| Possible adrenal insufficiency | Check morning cortisol and ACTH. An ACTH stimulation test may also be needed |
| Confirmed primary adrenal insufficiency | Treat with hydrocortisone or another glucocorticoid. Fludrocortisone may be needed when aldosterone production is low |
| Possible pituitary disease | Perform pituitary hormone testing and, when appropriate, pituitary imaging |
| Symptoms of low testosterone | Confirm the diagnosis with two early-morning testosterone tests and investigate the cause |
| Low DHEA-S after prednisone or another glucocorticoid | Do not stop the medicine suddenly. The prescriber should manage any taper or replacement plan |
| Isolated low DHEA-S with no identified disease | Routine DHEA supplementation is generally not recommended |
What Should a Man Do After a Low DHEA-S Result?
1. Check Whether the Result Is Low for Your Age
DHEA-S levels usually decline with age, and reference ranges vary between laboratories. A result marked "low" may be expected for an older man. It may also have little clinical importance when symptoms, other hormone tests and medical history are unremarkable.
A clinician should interpret the result alongside:
- Your age and symptoms
- The laboratory's reference range
- Current and recent medicines
- Medical history
- Other hormone and blood test results
DHEA-S is not the same as testosterone. A low DHEA-S result does not show that testosterone is low, and it does not by itself establish a need for DHEA treatment. If testosterone deficiency is suspected, diagnosis usually requires two separate early-morning testosterone tests.
2. Assess for Adrenal Insufficiency When Symptoms Fit
Low DHEA-S can occur when the adrenal glands do not produce enough hormones. Symptoms that need medical assessment include:
- Ongoing fatigue or muscle weakness
- Unexplained weight loss or reduced appetite
- Dizziness, especially when standing
- Low blood pressure
- Nausea, vomiting or abdominal pain
- Dehydration
- Salt cravings
- Darkening of the skin, particularly when Addison's disease is possible
Doctors commonly check cortisol and ACTH. An ACTH stimulation test may be used to assess how the adrenal glands respond. Electrolytes, renin and aldosterone can help identify the cause and type of adrenal disorder.
3. Review Medicines That Affect Adrenal Hormones
Long-term glucocorticoid treatment, or a recent reduction in the dose, can affect the hypothalamic-pituitary-adrenal system. Medicines that may be relevant include prednisone, prednisolone, dexamethasone and hydrocortisone.
Do not stop a prescribed glucocorticoid suddenly. Abrupt withdrawal can cause serious adrenal insufficiency or an adrenal crisis. The prescriber should provide a tapering or replacement plan.
How Is Low DHEA Treated When Adrenal Insufficiency Is Confirmed?
Treatment replaces the hormones that the adrenal glands cannot make.
- Hydrocortisone is commonly used to replace cortisol.
- Prednisone or prednisolone may be used in some situations.
- Fludrocortisone may be prescribed for primary adrenal insufficiency when aldosterone replacement is needed.
- Glucocorticoid doses may need to increase during serious illness, injury or surgery.
- People with established adrenal insufficiency generally need an emergency plan, medical identification and access to emergency glucocorticoid treatment.
The goal is to restore adequate adrenal hormone function and prevent complications such as adrenal crisis. It is not simply to raise the DHEA-S number.
Is DHEA Supplementation Recommended for Men?
Routine DHEA supplementation is not recommended for men solely because a blood test shows low DHEA-S. The Endocrine Society guideline discusses a monitored DHEA trial for some women with primary adrenal insufficiency, but it does not recommend routine DHEA replacement for men with isolated low DHEA-S.
DHEA supplements also vary in quality and can produce androgenic or estrogenic effects. Possible problems include:
- Acne and oily skin
- Headache or insomnia
- Mood changes or worsening of some mood disorders
- Reduced HDL cholesterol
- Breast enlargement in men
- Possible reduction in sperm count when combined with testosterone
- Concerns involving hormone-sensitive cancers
- Interactions with testosterone, estrogen and some antidepressants
Mayo Clinic advises against DHEA supplements because evidence for anti-aging and performance benefits is weak and safety concerns remain. Supplements are not FDA-approved to treat disease, and manufacturers do not have to establish effectiveness before marketing a product.
If an endocrinologist considers DHEA in an unusual case, treatment should have a defined purpose, a specific dose, symptom follow-up and laboratory monitoring. Over-the-counter DHEA should not replace an assessment for adrenal or pituitary disease. If you are weighing one up anyway, it is worth reading a DHEA supplement's product information first, since the strength per capsule and the full ingredient list are on the page.
What If Low DHEA Occurs With Low Libido or Erectile Dysfunction?
Low libido and erectile dysfunction do not show that DHEA is the cause. Other possible causes include low testosterone, medication effects, depression, sleep disorders, diabetes, vascular disease, relationship factors and other medical conditions.
The American Urological Association recommends diagnosing testosterone deficiency only when symptoms or signs are present and two separate early-morning total testosterone tests are low. A clinician may then check luteinizing hormone, follicle-stimulating hormone, prolactin and other possible causes.
Testosterone therapy is not a treatment for an isolated low DHEA-S result. In the United States, FDA-approved testosterone products are intended for men with low testosterone linked to a medical condition, rather than for nonspecific symptoms alone.
Can Diet, Exercise or Supplements Raise DHEA?
Healthy habits can support metabolic, cardiovascular and sexual health, but they are not proven treatments for medically significant adrenal hormone deficiency. No food, vitamin or over-the-counter supplement has been shown to safely correct an unexplained low DHEA-S level.
Useful steps include:
- Keep a regular sleep schedule.
- Exercise at a level that fits your health and fitness.
- Eat a balanced diet with enough calories and protein.
- Limit heavy alcohol use.
- Review prescription medicines and supplements with a clinician.
- Treat diagnosed conditions such as obesity, diabetes, sleep apnea or depression.
These measures support general health. They should not delay an assessment for adrenal insufficiency when symptoms suggest it.
When Is Low DHEA an Emergency?
Seek emergency care for possible adrenal crisis, especially if you have known or suspected adrenal insufficiency and develop:
- Severe weakness
- Repeated vomiting or diarrhea
- Severe abdominal, back or leg pain
- Confusion
- Fainting or loss of consciousness
- Severe dizziness, dehydration or very low blood pressure
Adrenal crisis requires urgent glucocorticoid treatment and intravenous fluids.
Practical Next Step
Make an appointment with a primary-care clinician or endocrinologist. Bring:
- The exact DHEA-S result, units and laboratory reference range
- Your age and symptoms
- A complete list of prescription medicines, steroids and supplements
- Previous cortisol, ACTH, testosterone, LH, FSH, prolactin, sodium and potassium results
This information helps the clinician decide whether the result reflects age, medication effects, adrenal disease, pituitary disease or another hormone problem.
