What was done
A systematic review and meta-analysis conducted under PRISMA guidelines searched 6 electronic databases (January 1990 to July 2016) and reference lists for randomized controlled trials. Eligible studies included patients diagnosed with erectile dysfunction allocated to aerobic, pelvic floor, or combined exercise interventions versus controls. Random-effects meta-analyses evaluated mean differences in erectile function scores, including International Index of Erectile Function (IIEF) scores, across intervention durations ranging from 8 weeks to 2 years.
What was found
Seven randomized controlled trials involving 478 participants met inclusion criteria. Pooled analysis showed a statistically significant improvement in erectile function score favoring exercise (mean difference 3.85, 95% CI 2.33 to 5.37). In sensitivity analyses, the mean difference in IIEF score remained statistically significant, ranging from 3.39 (95% CI 1.92 to 4.87) to 4.28 (95% CI 2.54 to 6.02). Benefits were reported for short-term and long-term protocols, and whether exercise was used alone or added to usual care.
Why it matters
This meta-analysis quantifies the therapeutic benefit of structured physical activity, particularly moderate-to-vigorous aerobic exercise, as an effective non-pharmacological intervention for erectile dysfunction.
Limits
The total sample size across all included trials was small (478 participants across 7 studies). Primary trials exhibited moderate to high risk of bias due to lack of participant/personnel blinding and questionable blinding of outcome assessors for subjective self-reported measures. Specific exercise modalities, baseline severity subgroups, and adverse events were not detailed in the abstract.
