Outcome Measures

Primary Outcomes (1)

  • Change From Baseline to 12 Week Endpoint in International Index of Erectile Function (IIEF) Erectile Function (EF) Domain Score

    The IIEF EF domain score was the sum of Questions (Q) 1 to Q5 and Q15 of the IIEF self-reported questionnaire. Q1 to Q5 were rated 0 (low/no EF) to 5 (high EF) and Q15 was rated 1 (no/low confidence) to 5 (high confidence). IIEF EF domain scores ranged from 1 to 30. Higher scores denoted better EF.

    Baseline, Week 12

Secondary Outcomes (9)

  • Change From Baseline to 12 Week Endpoint in the Percentage of "Yes" Responses on the Sexual Encounter Profile (SEP) Diary

    Baseline, Week 12

  • Change From Baseline to 12 Week Endpoint in IIEF Domain Scores (Intercourse Satisfaction, Orgasmic Function, Sexual Desire, and Overall Satisfaction)

    Baseline, Week 12

  • Change From Baseline to 12 Week Endpoint in the Percentage of Participants Who Return to "Normal" on the International Index of Erectile Function (IIEF) Scale (EF>25)

    Baseline, Week 12

  • Change From Baseline to 12 Week Endpoint in IIEF EF Domain Score Reported by Testosterone Concentration Subgroups
