This study examined the impact of piezoelectric shockwave therapy on erectile dysfunction in a randomised trial. A total of 126 men suffering from ED were enlisted and divided into two groups. Each participant underwent shockwave therapy or a sham treatment once weekly for five weeks, followed by a break of four weeks, and then another five weeks of treatment.
The primary outcome was an increase of at least five points on the International Index of Erectile Function erectile function domain (IIEF-EF) score. The secondary outcome was an improved Erection Hardness Scale (EHS) score of at least 3 in men who had a baseline score no higher than 2. The results did not demonstrate a significant effect of piezoelectric shockwave on ED, with success rates based on IIEF-EF score being 37.9% in the shockwave group and 38.3% in the sham group. Furthermore, success rates based on EHS score were 3.5% in the shockwave group and 6.7% in the sham group.
The results indicated that piezoelectric shockwave therapy was ineffective in treating ED, as there was no significant difference in erectile function between the two groups. This strengthens the growing body of evidence supporting electromagnetic shockwave therapy’s superiority.
Several other high-quality studies have demonstrated that electromagnetic shockwave therapy is a powerful and safe method for enhancing erectile function. Notable among these are studies by Ayala et al. (2017), Chung et al. (2015), Olsen et al. (2015), and Tsai et al. (2017).
