Outcome results

Primary

International Index of Erectile Function (IIEF) Erectile Function Subdomain (EF) Scores.

The IIEF-EF questionnaire has a total score ranging from 0 - 30 with the higher score indicating better erectile function.

Time frame: Baseline, Month 1, Month 3, Month 6, Month 9, and Month 12

Population: No statistical analyses have been performed or would be considered scientifically appropriate because actual enrollment fell well below target enrollment. Enrollment terminated early as a result of the COVID-19 pandemic.
