What can a DHEA-S test tell you?
A DHEA-S test helps evaluate how well your adrenal glands — two small organs that sit above your kidneys — are functioning. These glands make androgens like DHEA-S, and several other hormones, including cortisol and aldosterone.
Doctors may use the DHEA-S test to:
Assess whether your adrenal glands are producing too much or too little androgen.
Help evaluate low libido
Evaluate potential adrenal disorders, including Cushing’s syndrome, Addison’s disease, or adrenal tumors.
Help investigate early or delayed puberty in boys or hormone-related infertility in adults.
Since DHEA-S acts as a precursor to testosterone and other androgens, measuring it can give your provider insight into your overall androgen status — especially when total or free testosterone levels are inconclusive or when signs of hormonal imbalance are present.
What is being tested?
DHEA-S is the sulfated form of DHEA, a steroid hormone derived from cholesterol. It’s produced mainly in the adrenal cortex under stimulation from adrenocorticotropic hormone (ACTH) released by the pituitary gland.
DHEA-S circulates in the blood at much higher levels than DHEA and acts as a reservoir for androgen and estrogen synthesis in tissues such as the ovaries, skin, and brain.
In women, normal DHEA-S levels help support balanced hormone production, healthy energy levels, and overall well-being. Abnormally high or low levels can affect mood, libido, and metabolism, or signal issues with adrenal or pituitary function.
Where is the DHEA-S test typically included?
DHEA-S testing is usually ordered individually or as part of a targeted hormone or endocrine evaluation, especially when symptoms suggest an adrenal or androgen issue.
It may be included in:
Hormone or androgen panels (alongside testosterone, LH, FSH, and estradiol)
Adrenal function tests (alongside cortisol or ACTH)
Comprehensive endocrine workups for fatigue, infertility, or sexual dysfunction
In a telehealth setting, these may be available as part of an at-home hormone test that measures DHEA-S along with testosterone and cortisol to help provide a fuller picture of hormone balance.
Who should get a DHEA-S test?
Your provider may order a DHEA-S test if you have symptoms or risk factors that suggest a hormonal imbalance or adrenal problem.
Common Reasons to Test DHEA-S Include:
Low libido, erectile changes, or fatigue that might be related to low testosterone or adrenal dysfunction
Unexplained muscle loss or changes in body composition
Chronic stress, which can suppress or overstimulate adrenal hormone production
Gynecomastia (enlarged breast tissue) or other signs of hormone imbalance
Early puberty in boys or delayed puberty in adolescents
Evaluation of adrenal masses or tumors seen on imaging
Monitoring congenital adrenal hyperplasia (CAH) or other known endocrine disorders
Providers may also include DHEA-S when evaluating causes of low testosterone that don’t fit typical patterns, such as when total and free testosterone levels are normal but symptoms persist.
DHEA-S levels naturally decline with age — sometimes dropping by 80–90 percent from their peak by the time a man reaches his 70s. This gradual decline, called adrenopause, is normal and not necessarily a sign of disease. However, values far outside the expected age range on either side can signal that something more significant is going on.
