Outcomes
Primary Outcome Measures
Percent Change From Baseline in the Prostate Volume at Month 6
Percent change from baseline was calculated as the prostate volume at Month 6 minus the volume at baseline, divided by the prostate volume at baseline and multiplied by 100. Prostate volume was measured by transrectal ultrasound.
Secondary Outcome Measures
Percent Change From Baseline in the Prostate Volume at Month 3
Percent change from baseline was calculated as the prostate volume at Month 3 minus the volume at baseline, divided by the prostate volume at baseline and multiplied by 100. Prostate volume was measured by transrectal ultrasound.
Change From Baseline in the Prostate Volume at Month 6
Change from baseline was calculated as the prostate volume at Month 6 minus the volume at baseline. Prostate volume was measured by transrectal ultrasound.
Change From Baseline in the Prostate Volume at Month 3
Change from baseline was calculated as the prostate volume at Month 3 minus the volume at baseline. Prostate volume is measured by transrectal ultrasound.
Percent Change From Baseline in the Serum Dihydrotestosterone (DHT) at Month 6
Percent change from baseline was calculated as serum DHT at month 6 minus the value at baseline ,divided by the baseline value and multiplied by 100.
Percent Change From Baseline in the Serum DHT at Month 3
Percent change from baseline was calculated as the DHT at Month 3 minus the value at baseline, divided by the baseline value and multiplied by 100.
Change From Baseline in the Serum DHT at Month 6

Change from baseline was calculated as the value of DHT at Month 3 minus the baseline value.
Percent Change From Baseline in the American Urological Association Symptom Index (AUA-SI) Score at Month 6
Percent change from baseline is calculated as the AUA-SI score at month 6 minus the baseline AUA-SI score, divided by the baseline score and multiplied by 100.

Change From Baseline in the AUA-SI Score at Month 3
Change from baseline was calculated as the AUA-SI score at month 3 minus the baseline score. AUA-SI is a self-administered questionnaire that assesses the severity of benign prostate hyperplasia symptoms. Scores range from 0 to 35; mild, 0-7; moderate, 8-19; severe, 20-35.
Percent Change From Baseline in Maximum Urinary Flow Rate (Qmax) at Month 6

Percent Change From Baseline in Qmax at Month 3
Percent change from baseline was calculated as Qmax at Month 3 minus Qmax at baseline, divided by baseline Qmax and multiplied by 100. Qmax is the peak urinary flow measured by a uroflow meter.
Change From Baseline in Qmax at Month 6
Change from baseline was calculated as Qmax at Month 6 minus Qmax at baseline. Qmax is the peak urinary flow measured by a uroflow meter.
