Enter your information to understand your DHEA-S levels.

The History of DHEA-S

The broader story of steroid hormone chemistry traces back to German biochemist Adolf Butenandt, who isolated several key sex hormones during the late 1920s and 1930s, including estrone in 1929 and progesterone in 1934, establishing much of the foundational chemistry that later research on DHEA and its sulfated form would eventually build directly upon decades afterward in time. Butenandt's remarkable body of work earned him the 1939 Nobel Prize in Chemistry, though Germany's government at the time forced him to publicly decline it under considerable political pressure, and he wasn't able to actually receive the physical medal and diploma until 1949, years after the war had finally concluded completely. DHEA-S itself became clinically measurable and properly understood only once steroid biochemistry techniques matured considerably further through the mid-20th century, decades later still.

What DHEA-S Actually Is

DHEA-S is a steroid hormone produced almost entirely by the adrenal glands, with the sulfate group attached specifically to make the molecule far more stable and considerably longer-lasting in the bloodstream than the related, unsulfated form of DHEA circulating alongside it in the body. Because it doesn't fluctuate throughout the day the way cortisol famously does, DHEA-S serves as a reliable snapshot of overall adrenal androgen production regardless of what specific time of day a blood sample happens to be drawn from a given patient. It also functions as a raw material that other tissues throughout the body can convert into more potent hormones, including testosterone and estrogen, as biological circumstances require at any given moment in time or need. Levels typically peak during young adulthood and decline gradually and quite predictably with advancing age afterward, year by year steadily and consistently.

How DHEA-S Is Measured

DHEA-S is most commonly measured using chemiluminescent immunoassay techniques, in which antibodies designed to bind the hormone trigger a light-emitting chemical reaction whose intensity is precisely measured by automated laboratory equipment within a matter of just a few short minutes. Because DHEA-S circulates at considerably higher and far more stable concentrations than many other steroid hormones in the body, testing doesn't require the careful time-of-day scheduling that cortisol testing famously demands, making it a genuinely more convenient test to schedule for both patients and busy laboratories alike, at virtually any hour of the day or night.

Scientists Behind the Science

Adolf Butenandt's pioneering isolation of multiple sex steroid hormones throughout the late 1920s and 1930s provided the essential chemical foundation that all later adrenal hormone research, including DHEA-S specifically, would eventually build upon over the following many decades of work. His parallel work alongside other steroid chemists of that same remarkably productive era helped establish the broader biochemical map connecting the adrenal glands, the gonads, and the many related hormones each of them produces throughout an entire human lifetime. That foundational mapping work remains directly relevant today, underlying how modern laboratories interpret DHEA-S alongside cortisol and other adrenal hormones as part of one single, interconnected diagnostic picture used in clinics everywhere around the entire world today.
