RESUMO
Dehydroepiandrosterone (DHEA) and its sulphated metabolite (DHEA-S) are endogenous steroid hormones, synthesized by the adrenal cortex, gonads and CNS. The secretion profile changes with age and depends on the sex. Human DHEA and DHEA-S levels decline linearly and systematically with age and suggest the potential importance of that parameter as a biomarker of ageing. The counteraction of DHEA against atherosclerotic disease, cancer growth, diabetes mellitus, insulin resistance, obesity and the influence on immunological functions are observed in researches. DHEA influences the condition of mind, cognition functions, memory and well-being. DHEA hormonal replacement therapy is expected to lengthen human life by the stoppage of physiological degeneration changes and prevention of age-related clinical disorders.
