Description and Applications:
Dehydroepiandrosterone/dehydroepiandrostenedione (DHEA, more correctly didehydroepiandrosterone), also known as androstenolone as well as 3β-hydroxyandrost-5-en-17-one or 5-androsten-3β-ol-17-one, is an important endogenous steroid hormone. In its pharmaceutical drug form it is called prasterone (INN). It is the most abundant circulating steroid hormone in humans, in whom it is produced in the adrenal glands, the gonads, and the brain, where it functions predominantly as a metabolic intermediate in the biosynthesis of the androgen and estrogen sex steroids. However, DHEA also has a variety of potential biological effects in its own right, binding to an array of nuclear and cell surface receptors, and acting as a neurosteroid.
A review in 2003 found the then-extant evidence sufficient to suggest that low serum levels of DHEAS may be associated with coronary heart disease in men, but insufficient to determine whether DHEA supplementation would have any cardiovascular benefit.
A meta-analysis of intervention studies shows that DHEA supplementation in elderly men can induce a small but significant positive effect on body composition that is strictly dependent on DHEA conversion into its bioactive metabolites such as androgens or estrogens.
DHEA and other adrenal androgens such as androstenedione, although relatively weak androgens, are responsible for the androgenic effects of adrenarche, such as early pubic and axillary hair growth, adult-type body odor, increased oiliness of hair and skin, and mild acne. Women with complete androgen insensitivity syndrome (CAIS), who have a non-functional androgen receptor (AR) and are immune to the androgenic effects of DHEA and other androgens, have absent or only sparse/scanty pubic and axillary hair and body hair in general, demonstrating the role of DHEA, testosterone, and other androgens in body hair development at both adrenarche and pubarche.
As a neurosteroid, DHEA has important effects on neurological and psychological functioning.
In United States
DHEA is legal to sell in the United States as a dietary supplement. It is currently grandfathered in as an "Old Dietary Ingredient" being on sale prior to 1994. DHEA is specifically exempted from the Anabolic Steroid Control Act of 1990 and 2004. It is banned from use in athletic competition.
Sports and Athletics
DHEA is a prohibited substance under the World Anti-Doping Code of the World Anti-Doping Agency, which manages drug testing for Olympics and other sports. In January 2011, NBA player O.J. Mayo was given a 10-game suspension after testing positive for DHEA. Mayo termed his use of DHEA as "an honest mistake," saying the DHEA was in an over-the-counter supplement and that he was unaware the supplement was banned by the NBA. Mayo is the seventh player to test positive for performance-enhancing drugs since the league began testing in 1999. Rashard Lewis, then with the Orlando Magic, tested positive for DHEA and was suspended 10 games before the start of the 2009-10 season. 2008 Olympic 400 meter champion Lashawn Merritt has also tested positive for DHEA and was banned from the sport for 21 months. Yulia Efimova, who holds the world record pace for both the 50-meter and 200-meter breaststroke, and won the bronze medal in the 200-meter breaststroke in the 2012 London Olympic Games, tested positive for DHEA in an out-of-competition doping test.
In the United States, DHEA or DHEAS have been advertised with claims that they may be beneficial for a wide variety of ailments. DHEA and DHEAS are readily available in the United States, where they are marketed as over-the-counter dietary supplements.
