DHEA for Both Sexes
have heard that DHEA and Pregnenolone are more beneficial for men than
women. Is this true?
MS, Jackson Hole, WY
A All of the
returns are not in, but at face value this doesn't seem to be true, because
the levels of both hormones decline with age in both men and women at about
the same rate. More importantly, recent quality-of-life studies suggest
that women benefit as much as men, if not more.
A recent British study surveyed 140 women with regard to determinants
of sexuality and well-being, and correlated their answers with hormonal
analysis of blood samples. Measures included sexual function,
sexual experience scales, and a multiple choice affect adjective check
list. Determinants were evaluated using multiple regression analysis, included
age, menopausal status, BMI, smoking, ovarian steroids and adrenal androgens.
While none of the hormonal parameters significantly predicted measures
of sexuality, the most important predictors were other aspects of the sexual
relationship, sexual attitudes and measures of well-being. The best predictor
of both well-being and depression was tiredness. The only hormone positively
related to well-being was DHEA (dehydroepiandrosterone).
In another recent study, DHEA sulfate levels were associated with body
fat distribution as measured by waist-hip ratio in a sample of 151 consecutively
enrolled healthy premenopausal women aged 18 to 24 years. In
other words, the higher the level of DHEA sulfate (into which DHEA is freely
converted in he body), the lower the level of obesity. Differences in concentration
of circulating DHEAS and total testosterone are independently associated
with the waist-hip ratio in premenopausal women, providing epidemiologic
support to the "neuroendocrine dysregulation" hypothesis for
the pathogenesis of central obesity. In the famous Yen study, after 6 months
of supplementing with 100 mg of DHEA, both men and women had increased
levels of lean body mass.
Women with autoimmune diseases, like lupus and rheumatoid arthritis
have been found to have lower plasma androgen levels than controls. The
case for the use of supplemental DHEA has thus received support for the
treatment of lupus. Lupus is four times more common in women
than in men. In a study involving 11 patients with lupus, several days
of therapy with pregnenolone resulted in increased feelings of well-being
as well as improved joint pain and significantly reduced skin rash.
It is also hypothesized by Eugene Roberts, Ph.D. (author of principal
articles on pregnenolone and DHEA) that pregnenolone may be able to obviate
the long-term virilizing side-effects of DHEA in some women.
Moreover, ". . . pregnenolone will also reduce the excessive ketosteroid
excretion of pathologic origin which occurs in virilism in women."
