Meta-analysis of Results of Testosterone Therapy on Sexual Function Based on International Index of Erectile Function Scores

We investigated the effect of testosterone treatment on sexual function by performing a meta-analysis of all available studies that used the most frequently used assessment tool, the International Index of Erectile Function. We found that testosterone treatment significantly improves erectile dysfunction, as well as other aspects of sexual function, in men with testosterone deficiency. This treatment may be all that is required for hypogonadal men with milder erectile dysfunction; however, additional treatments may be necessary in more severe cases.
