Primary Outcome Measures:
  • Response of treatment for 4 injections at 1 year; score on an IIEF-5 [ Time Frame: 4 injections at 1 year for each subject, at 12,30,46 weeks. ]

Secondary Outcome Measures:
  • Testosterone level [ Time Frame: at 6,12,18,36,46 weeks ]

Enrollment: 30
Study Start Date: January 2007
Study Completion Date: May 2011
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Testosterone Undecanoate,1000mg
    duration for 4 injections
    Other Name: Nebido 1000 mg
Detailed Description:
Hypogonadism is a pathophysiologic and clinical factor in a substantial number of patients with ED,and data indicate that a threshold level of testosterone is necessary for normal erectile function.Testosterone therapy is clearly indicated in hypogonadal patients and is beneficial in other patients with ED and hypogonadism.However,testosterone efficacy as monotherapy for ED could be limited,and combination therapy with testosterone and other ED treatments,such as PDE-5 inhibitors may be valuable in certain subpopulations of patients.
