Endocrine status in elderly men with lower urinary tract symptoms: correlation of age, hormonal status, and lower urinary tract function. The Prostate Study Group of the Austrian Society of Urology

To correlate endocrine parameters in elderly men with lower urinary tract symptoms (LUTS) to patient age and clinical parameters such as prostate volume, prostate-specific antigen (PSA) levels, and uroflowmetry and to compare the clinical and endocrinologic parameters in men with or without hypogonadism. Men (40 years old or older) with untreated LUTS as defined by an International Prostate Symptom Score (IPSS) of 7 or greater due to benign prostatic hyperplasia were included in this study and underwent the following investigations: IPSS, free uroflow study, postvoid residual volume, transrectal ultrasound for assessment of prostate volume, serum PSA determination, and an endocrine study, including testosterone, human luteinizing hormone, human follicle-stimulating hormone, prolactin, dehydroepiandrostendione-sulphate (DHEA-S), and prolactin. Three hundred twelve men (mean age 62.8 +/- 10.6 years, range 40 to 91) were analyzed. The serum levels of estradiol (correlation coefficient [r] = 0.19), human luteinizing hormone (r = 0.32), human follicle-stimulating hormone (r = 0.19), and DHEA-S (r = -0.39) correlated (P
