Questions about this test
How is DHEA different from DHEA-S?
DHEA changes through the day, while DHEA-S, its stored form, is steadier. DHEA-S is more often used for adrenal checks.
Does DHEA fall with age?
Yes. DHEA peaks in early adulthood and falls steadily with age.
Should I take DHEA supplements for fertility?
Some clinics discuss DHEA for women with low ovarian reserve, but the evidence is limited. Only take it if your fertility doctor advises.
