Outcomes
Primary Outcome Measures
Change in SHIM (Sexual Health Inventory for Males) Score at 6 Months After Initial Screening Visit.
SHIM range is 0-25. 0= no sexual activity;1-7 severe ED; 8-11 Moderate ED; 12-16 Mild to Moderate ED; 17-21 Mild ED
Secondary Outcome Measures
Change in the IIEF (International Index of Erectile Function) Score 6 Months After the Initial Screening Visit.
There are 15 questions, each divided into 5 domains. Maximum score is 75 = best function, and minimum is 5 = worst function
Change in the ADAM (Androgen Deficiency in the Aging Male)Score 6 Months After the Initial Screening Visit.
ADAM scores of one evaluated patient. ADAM is 10 questions ("yes" or "no" answers) and if you answer yes to question 1 or 7 or "yes" to any 3 questions you are said to test "positive" to the ADAM questionnaire.
Change in the EPIC (Expanded Prostate Cancer Index Composite) Score 6 Months After the Initial Screening Visit.
EPIC is scored from 0 -100,lower EPIC score= worse, higher EPIC score= better

5. Study Description
Brief Summary
The purpose of this study is to determine the effectiveness of testosterone replacement therapy (TRT) in men following surgery to remove the prostate in improving erectile function. Subjects will be randomized (like flipping a coin) to one of two groups. One group will receive Testim® (testosterone gel) 5 g per day plus Viagra 25 mg every night and the other will receive Placebo-Testim® 5 g per day plus Viagra 25 mg every night.
Subjects will begin drug treatment 3 months after the initial screening visit and will take study drug for 3 months only. Participation will end at the end of the 6-month visit.
Detailed Description
There was only one patient who began treatment with the study drug. After blind was broken, it was noted that he received placebo Testim and Viagra.
