NCT00848497

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.
