Are you concerned that your male hormones are declining with age? DHEA is a sex hormone (androgen) that’s created in men and, to a lesser extent, in women. Your body converts it into other hormones, namely testosterone and oestrogen. Measuring your DHEAS can help to diagnose adrenal insufficiency. Levels may also be elevated if you have polycystic ovaries. DHEA (Dehydroepiandrosterone) is an androgen hormone produced from cholesterol that your body converts into other hormones, including testosterone and oestrogen. Most of the DHEA in your body exists in your blood in the sulphated form, DHEAS, which we measure in this test. Measuring DHEAS can help to investigate adrenal insufficiency and tell you whether your levels are normal for your age. DHEAS can also help to find polycystic ovaries as levels are likely to be elevated.
