Brief Summary
The purpose of this trial is to evaluate the effect of tadalafil 5 milligrams (mg) daily for 8 weeks compared to placebo on prostatic blood perfusion in men with signs and symptoms of Benign Prostatic Hyperplasia (BPH), measured by resistive index (RI) in the prostate transition zone.

Outcome Measures
Primary Outcomes (1)
Change From Baseline to 8-Week Endpoint in Arterial Resistive Index (RI) in the Prostate Transition Zone
Arterial RI was a measure of vascular resistance using Doppler ultrasound. RI was the ratio of (peak systolic velocity - end diastolic velocity)/peak systolic velocity, and increased as resistance to blood flow increased. The least squares (LS) mean was estimated from a mixed-effects model with repeated measures (MMRM) that included fixed effects for treatment, region, visit, and treatment-by-visit interaction, baseline as a covariate, a random effect of participant within treatment, and an unstructured covariance matrix.
Baseline, Week 8
Secondary Outcomes (3)
Change From Baseline to 4-Week Endpoint in Arterial Resistive Index (RI) in the Prostate Transition Zone
Baseline, Week 4
Change From Baseline to 4 and 8 Weeks in Arterial Resistive Index (RI) in the Prostate Peripheral Zone and Bladder Neck
Baseline, Week 4 and Week 8
Change From Baseline to 4 and 8 Weeks in Color Pixel Intensity (CPI) in the Prostate Transition Zone, Peripheral Zone, and Bladder Neck
Baseline, Week 4 and Week 8
Study Arms (2)
5 milligrams (mg) Tadalafil
