PURPOSE: We performed a randomised controlled study regarding the effects of androgen replacement therapy (ART) on lower urinary tract symptoms (LUTS) in hypogonadal men with benign prostate hypertrophy (BPH). METHODS:Fifty-two patients with hypogonadism and BPH were randomly assigned to receive testosterone (ART group) as 250 mg of testosterone enanthate every 4 weeks or to the untreated control group. We compared International Prostate Symptom Score (IPSS), uroflowmetry data, post-voiding residual volume (PVR) and systemic muscle volume at baseline and 12 months after treatment. RESULTS:Forty-six patients (ART group, n=23; control, n=23) were included in the analysis. At the 12-month visit, IPSS showed a significant decrease compared with baseline in the ART group (15.7 +/- 8.7 vs. 12.5 +/- 9.5; p<0.05). No significant changes were observed in the control group. The ART group also showed improvement in maximum flow rate and voided volume (p<0.05), whereas no significant improvements were observed in the controls. PVR showed no significant changes in either group. In addition, the ART group showed significant enhancement of mean muscle volume (p<0.05), whereas no significant changes were seen in the controls. CONCLUSION: ART improved LUTS in hypogonadal men with mild BPH.
