|---|---|---|
| IIEF (International Index of Erectile Dysfunction) questionnaire scores | 30 days | Mean change in IIEF scores. There are five specific areas addressed including Erectile Function (questions:1-5 & 15;score range: 0-5, maximum score:30); Orgasmic Function (questions:9-10; score range:0-5; maximum score:10); Sexual desire (questions:11-12; score range:1-5; maximum score:10); Intercourse satisfaction (questions:6-8; score range:0-5; maximum score:15); Overall satisfaction (questions:13-14; score range:1-5; maximum score:10). The lower the score represents greater dysfunction within each domain. |
