Oral DHEA is not a reliable treatment for low libido. In a 52-week randomized trial of 93 postmenopausal women, 50 mg of DHEA daily did not improve sexual activity, sexual function or quality of life compared with placebo. The trial was published in.
Evidence in men is also too limited to recommend DHEA as a libido treatment. DHEA may help indirectly when vaginal dryness or painful sex is reducing sexual interest, but that is different from increasing libido itself.
DHEA and Libido at a Glance
| Question | Evidence-based answer |
|---|---|
| Does oral DHEA reliably increase libido? | No |
| Can DHEA help some postmenopausal women? | Possibly, but benefits are inconsistent and generally small |
| Does DHEA treat low libido in men? | It is not an established treatment |
| Can vaginal DHEA help sexual comfort? | Yes. Prescription vaginal prasterone can treat painful sex caused by menopausal vaginal atrophy |
| Should you take DHEA without medical advice? | No. DHEA affects androgen and estrogen pathways |
Why DHEA Is Thought to Affect Sexual Desire
Dehydroepiandrosterone, or DHEA, is a hormone produced mainly by the adrenal glands. The body can convert DHEA into other hormones, including testosterone and estrogen. DHEA levels usually decline with age, but a lower DHEA level does not prove that supplementation will restore libido.
Libido can also be affected by medication side effects, depression, anxiety, stress, relationship difficulties, menopause, erectile problems, vaginal dryness and pain.
What Does the Research Show?
Research does not show a consistent libido benefit from systemic DHEA.
A systematic review and meta-analysis of randomized trials found that systemic DHEA did not significantly improve libido or sexual function in postmenopausal women with normal adrenal function. The findings were uncertain because the studies were small, inconsistent and often at risk of bias.
Some earlier reviews found a small statistical improvement in libido. However, the evidence quality was low, and the Endocrine Society concluded that it was not strong enough to recommend routine DHEA use for women.
Oral DHEA Is Different From Vaginal Prasterone
Prescription vaginal prasterone, sold in the United States as Intrarosa, is a local DHEA treatment approved for moderate to severe painful sex caused by menopausal vulvar and vaginal atrophy. It is not approved as a general treatment for low sexual desire.
Vaginal prasterone may improve sexual comfort by reducing vaginal symptoms. If pain or dryness has been suppressing desire, better comfort may make sexual activity more appealing. That does not mean the treatment directly increases libido.
Does DHEA Help Libido in Men?
DHEA is not a proven libido booster for men. Low desire, erectile difficulties, fatigue and reduced morning erections can have several causes, including consistently low testosterone, medication effects, sleep problems, depression, diabetes and cardiovascular disease.
The Endocrine Society recommends considering testosterone treatment for men with compatible symptoms and consistently low testosterone after proper evaluation. That recommendation does not support using over-the-counter DHEA as a substitute for diagnosis or testosterone therapy.
When Might DHEA Be Considered?
DHEA may be discussed with a clinician in specific situations:
- Menopausal vaginal dryness or painful sex, when prescription vaginal prasterone may be appropriate.
- Certain adrenal or pituitary disorders, although routine DHEA treatment remains unsupported because benefits and long-term safety are uncertain.
- Low libido when a clinician is investigating several possible causes and reviewing hormone-related conditions.
The Endocrine Society does not recommend routine DHEA use even for women with adrenal insufficiency because the available evidence is limited. Before that discussion it can help to see what is actually sold; these are DHEA capsules for adults, with the dose and ingredient list on the page.
What Are the Risks of Taking DHEA?
DHEA can cause unwanted hormonal effects, and its long-term safety is uncertain. Possible problems include:
- Acne and oily skin
- Unwanted facial or body hair growth in women
- Mood changes or mania in people with mood disorders
- Reduced HDL cholesterol
- Hormonal effects when combined with estrogen or testosterone
- Potential concerns involving hormone-sensitive cancers
- Unknown long-term safety
DHEA should generally be avoided during pregnancy and breastfeeding. It should also be used cautiously by people with hormone-sensitive cancer, cardiovascular disease, high cholesterol or mood disorders. Discuss DHEA with a healthcare professional before using it, especially if you take hormone therapy, antidepressants or other regular medicines.
What Should You Do Instead of Starting DHEA?
Persistent or distressing low libido calls for an evaluation of possible causes rather than self-treatment based on a DHEA level.
A clinician may review:
- Medication effects, including antidepressants, hormonal contraceptives, blood-pressure medicines and opioids.
- Menopause-related symptoms, such as vaginal dryness, pain or hot flashes.
- Hormonal or medical conditions, based on symptoms and medical history.
- Mental health and relationship factors, including anxiety, depression, stress and sexual pain.
- Testosterone levels in men when symptoms suggest possible hypogonadism.
Bottom Line
Oral DHEA is not a reliable treatment for low libido. Vaginal prasterone can improve menopausal vaginal symptoms and painful sex, but it is not a general treatment for low sexual desire. New, persistent or distressing low libido is better addressed through medical evaluation than by starting an over-the-counter DHEA supplement. If you are weighing a product anyway, you can see how DHEA supplements on Amazon are labeled and take those details to the evaluation.
