When your PCOS blood test comes back showing high DHEA-S, many women feel confused: isn’t PCOS an ovary problem? Why are the adrenal glands suddenly involved? DHEA-S (dehydroepiandrosterone sulfate) is the one major androgen produced almost entirely by the adrenal glands rather than the ovaries. So when it is elevated, it signals that part of your excess androgens may be coming from this “second source”. This article explains what high DHEA-S actually means, why it is not a separate diagnosis, and what calm, sensible steps make sense for women with PCOS in Malaysia.

DHEA-S: an adrenal-specific marker

The body makes androgens from two main places: the ovaries and the adrenal glands (two small glands sitting on top of the kidneys). Most of the androgen excess in PCOS, such as testosterone, comes from the ovaries. But DHEA-S is secreted almost exclusively by the adrenals. This is why doctors treat it as an “adrenal-specific marker”.

Among women with PCOS, roughly 20 to 30 percent have DHEA-S levels above the age-adjusted normal range. That means most women with PCOS actually have normal DHEA-S. When it is genuinely high, it usually occurs alongside ovarian androgens rather than on its own. Only in a small fraction of women (estimated around 5 percent) does the androgen excess come from the adrenals alone.

One detail that often goes unnoticed: DHEA-S naturally declines with age. A value considered “high” for a woman in her 20s may differ from one in her 40s. That is why a good laboratory reports reference ranges by age group. Do not compare your number with an older or younger friend without taking age into account.

Is “adrenal-type PCOS” a real diagnosis?

The term “adrenal-type PCOS” is popular on social media and health blogs, but it is not an official diagnostic category in the 2023 international PCOS guideline (which Malaysia also follows). No test gives you a label saying “you have adrenal PCOS”. Instead, the term is just an informal way to describe women whose androgen excess is largely driven by adrenal DHEA-S, with lower ovarian testosterone.

Why is this distinction still useful? Because it helps doctors think about the cause and rule out other conditions. High DHEA-S prompts a doctor to check whether there is another adrenal reason, rather than assuming everything is PCOS. The PCOS diagnosis itself still rests on the same criteria (the Rotterdam criteria: a combination of irregular periods, signs of high androgens, and polycystic ovaries on a scan), and does not change simply because your DHEA-S is high.

If you were recently diagnosed and are still making sense of all these numbers, our guide for the newly diagnosed lays out the first steps in order.

Why DHEA-S is not the first test for PCOS

This often surprises women: DHEA-S is actually not the main androgen test used to diagnose PCOS. According to the 2023 international guideline, the first-line blood tests for assessing high androgens are total testosterone and free testosterone (or the free androgen index). DHEA-S is considered only as a second-line test, usually when testosterone is not elevated but androgen symptoms are clearly present, because its specificity is lower.

This means a mildly raised DHEA-S on its own is not strong evidence of anything. It is just one piece of the bigger picture. A doctor will weigh it alongside your symptoms (acne, hirsutism meaning excess male-pattern hair, thinning scalp hair), your menstrual cycle, and other tests. To understand the main PCOS androgen more fully, read our article on high testosterone in PCOS, which explains the difference between total testosterone, free testosterone, and SHBG.

Follow-up tests when DHEA-S is high

High DHEA-S, especially if very high or rising sharply, prompts a doctor to consider two other conditions that can mimic PCOS. This is part of a thorough assessment, not a reason to panic.

Non-classic (late-onset) congenital adrenal hyperplasia (NCAH). This genetic condition can look almost identical to PCOS, with irregular periods and signs of high androgens. The screening test is 17-hydroxyprogesterone (17-OHP), taken in the morning and in the follicular phase of the cycle (the first half of the menstrual cycle). Evidence shows a baseline 17-OHP of at least 2 ng/mL (about 6 nmol/L) warrants further investigation, while a value of at least 10 ng/mL (about 30 nmol/L) confirms NCAH. Interestingly, in NCAH the DHEA-S is often normal, so DHEA-S alone cannot tell the two apart. It is the 17-OHP that matters.

Adrenal tumour (very rare). When DHEA-S exceeds around 700 µg/dL, doctors typically investigate the possibility of a tumour on the adrenal gland, usually with imaging and additional tests. This is very uncommon, but it is the reason extreme values or rapidly changing symptoms (a deepening voice, male-pattern muscle gain, an enlarging clitoris) should be referred promptly. For a full picture of the signs that need urgent referral, see the summary in our PCOS hormones hub.

Stress, cortisol and the adrenals: beware the myth

Because DHEA is also linked to the adrenals, a lot of online content overstates the connection between “adrenal PCOS”, stress, and cortisol, as if reducing stress alone would lower DHEA-S. The reality is that evidence for a direct link is limited and not as strong as often claimed. Chronic stress does affect overall health and can indirectly worsen PCOS symptoms, but there is no strong evidence that stress-relief techniques specifically will “normalise” a high DHEA-S.

More importantly, a safety warning: DHEA supplements (sold as anti-ageing or energy boosters) actually raise androgen levels. For women with PCOS, this can worsen acne, hirsutism, and hair loss. DHEA supplements are not recommended for general PCOS and should be avoided, especially during pregnancy and breastfeeding. Do not take DHEA on your own initiative without a doctor’s advice. For a discussion of cortisol and stress in PCOS, we have a separate article in the PCOS hormones hub.

A practical approach for Malaysian women

The most sensible first step is to discuss your results with a doctor who can interpret them in full context, not as a single number. In Malaysia, the public pathway starts at a KKM Klinik Kesihatan (costing as little as RM1 for citizens, including basic investigations), which can then refer you to a hospital O&G or endocrine clinic if needed. Specialist follow-up is around RM5. Private clinics charge more and vary widely, so check directly with your chosen clinic.

For women who are unmarried or have no history of intercourse, a transabdominal ultrasound (through the abdomen) is the first-line method in Malaysia, not the transvaginal one. PCOS can still be diagnosed without a transvaginal scan, so this will not hold back your assessment.

If you fast during Ramadan, a controlled study found that FSH, LH, testosterone, and insulin levels in women with PCOS were largely unchanged during Ramadan. However, if you take metformin or diabetes medication, discuss adjusting your dosing times with your doctor. Finally, remember that PCOS, even with a different androgen source, still raises long-term risks such as type 2 diabetes and heart disease. Many Malaysian women are unaware of this. Regular monitoring (fasting glucose, HbA1c, lipid profile) is just as important as managing androgen symptoms.

When to see a doctor

See a doctor for a full assessment if you have irregular periods together with signs of high androgens, or if a test shows unexplained high DHEA-S. Seek a prompt referral if androgen symptoms appear or worsen quickly (a deepening voice, marked muscle growth, an enlarging clitoris), because sudden changes need earlier investigation. Your doctor, not an online chart, is the right person to interpret the combination of your numbers and symptoms.
