Abstract
Context: The efficacy and safety of testosterone replacement therapy (TRT) in hypogonadal men remain incompletely understood.
Objective: To conduct a systematic review and meta-analysis of randomized clinical trials (RCT) to determine the effects of TRT on patient-important outcomes and adverse events in hypogonadal men.
Data Sources: We searched Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Database of Systematic Reviews, Ovid Cochrane Central Register of Controlled Trials, and Scopus from inception to March 2th, 2017.
Study selection: RCTs that assessed the efficacy and adverse events of TRT of at least 12 weeks compared with placebo in adult men with hypogonadism, defined by morning testosterone ≤300 ng/dL and at least one symptom or sign of hypogonadism.
Data extraction: Reviewers working independently and in duplicate assessed the quality of the trials and collected data on patient characteristics, interventions, and outcomes.
Data synthesis: We found 11 publications, reporting on 4 eligible trials (including 1,779 patients) at low risk of bias. Compared to placebo, TRT was associated with a small but significant increase in sexual desire or libido [standardized mean difference (SMD): 0.17, 95% CI 0.01, 0.34] (n=1383), erectile function [SMD: 0.16, 95% CI 0.06, 0.27] (n=1344), and sexual satisfaction [SMD: 0.16, 95% CI 0.01, 0.31] (n=676), but had no effect on energy or mood. TRT was associated with an increased risk of developing erythrocytosis [relative risk: 8.14, 95% CI: 1.87, 35.40] (n=1579) compared to placebo, but had no significant effect on lower urinary tract symptoms (LUTS).
Conclusion: In hypogonadal men TRT improves sexual desire, erectile function, and sexual satisfaction, however it increases the risk of erythrocytosis.
