The prevalence and predictors of androgen deficiency in Taiwanese men with lower urinary tract symptoms

AbstractObjectiveTo evaluate the prevalence and associated factors of androgen deficiency (AD) in men with lower urinary tract symptoms (LUTS).Materials and methodsFrom November 2011 to March 2012 in a single institute, we enrolled 122 men with LUTS. AD was defined as having a total testosterone level less than 3 ng/mL. The underlying disease and associated factors related to AD were analyzed with univariate and multivariate methods.ResultsOf the 122 patients, 55.3% reported having AD. The AD group had a larger waist circumference (WC) and higher blood white cell count (WBC) in the univariate analysis but in multivariate analysis, only WC >90 cm was an independently associated factor of AD (OR: 2.864, p = 0.042).ConclusionA considerable portion of men with LUTS had AD. The major associated factor of AD was WC >90 cm. WC should thus be measured routinely in men with LUTS and physicians should pay more attention to those with WC >90 cm in order to identify and treat these patients earlier to improve symptoms of LUTS and life quality
