Trial Outcomes & Findings for Treatment of Erectile Dysfunction II (NCT NCT01037218)

NCT ID: NCT01037218

Last Updated: 2015-06-19

Results Overview

Erectile Function domain: 0 - 5 scoring scale for each of 6 questions (scale: 0/min/poor - 30/max/good). Over last month: How often were you able to get erection? When you had erections with stimulation, how often were your erections hard enough for penetration? When you attempted intercourse, how often were you able to penetrate your partner? How often were you able to maintain your erection after penetrating your partner? How difficult was it to maintain your erection to completion of intercourse? How do you rate your confidence that you can get \& keep your erection?
