title: Association of DHEA-S and estradiol serum levels to symptoms of aging men.
abstract: OBJECTIVE
  A number of interactions between age-related changes in serum levels of dehydroepiandrostendione sulfate (DHEA-S) and estradiol and symptoms of aging men have been proposed, yet data regarding this issue are scant. We therefore set up a prospective study to analyze these associations.
  
  
  METHODS
  In a prospective, cross-sectional study, men aged 45-85 years were recruited. All men completed a questionnaire containing 38 items covering a number of aspects of the aging male. Questionnaires were compiled by using items from previously published and validated questionnaires. Several socioeconomic parameters were also determined. In parallel, serum levels of testosterone, free testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH), DHEA-S, estradiol, sex hormone binding globulin and prostate-specific antigen (PSA) were quantified by commercially available immunoassays.
  
  
  RESULTS
  A total of 375 men with a mean age of 59.9 +/- 9.2 years (mean +/- standard deviation) were analyzed. Average DHEA-S and estradiol levels of 135.8 +/- 90.9 micrograms/dl and 29.7 +/- 14.6 pg/ml, respectively, were recorded. DHEA-S serum levels were negatively correlated to patient age, sexual function score, total score and PSA. Estradiol serum levels were positively correlated to testosterone and free testosterone. None of the other scores or questions revealed a correlation with DHEA-S or estradiol serum levels.
  
  
  CONCLUSIONS
  This prospective study elucidates only small interactions between partial androgen deficiency of the aging male (PADAM)-related symptoms and serum levels of DHEA-S and estradiol. Nevertheless, the data suggest an impact of DHEA-S on sexual function.
