Effects of Low-Intensity Shock Wave Therapy on Erectile Function and Penile Vascular Parameters in Men with Erectile Dysfunction: A Systematic Review and Meta-Analysis of Randomized Controlled Studies

LiSWT provides modest improvements in IIEF scores but fails to produce significant changes in other functional or vascular parameters. These findings suggest that while LiSWT may offer some benefit, the clinical relevance is limited for most patients. Current evidence does not support its routine inclusion in ED treatment algorithms. Future research should focus on identifying patient subgroups most likely to experience significant and sustained improvements from this therapy.
