| Abstract: | Many animal and human studies show that supraphysiological doses of dehydroepiandrosterone (DHEA) can influence body composition and carbohydrate and lipid metabolism. Most studies have concentrated on women and have not been randomized, thus creating controversial results. With this in mind, we designed a cross-over double-blind placebo-controlled study of 12 men aged 59.0 ± 4.8 years, who received either 50 mg/24 h DHEA or placebo for 3 months to assess the influence of DHEA on the content and distribution of fat tissue and serum insulin, glucose, total cholesterol, low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol levels, as well as testosterone, estradiol, DHEA-sulfate (S), prostate-specific antigen (PSA) concentrations and indexes of insulin sensitivity and resistance. Patients were recruited from university employees attending for periodic health checks, with normal hepatic and renal function with endogenous DHEA-S level < 1500 ng/dl. Our results did not reveal any significant changes in study parameters, apart from a statistically significant increase in DHEA-S levels after therapy with active substance. |
