Shockwave therapy effective for erectile dysfunction
The total number of shockwave therapy significantly affects treatment efficacy, according to a recent study, which has shown improved sexual function in erectile dysfunction patients undergoing 12 vs 6 shockwave therapy sessions.
The researchers randomized 42 adults with vasculogenic erectile dysfunction to receive low-intensity shockwave therapy either once (group A; n=21) or twice (group B; n=21) a week for 6 consecutive weeks. Six additional sessions were offered for the second phase of the study, where group A received two sessions per week and group B received one session per week.
In the entire cohort the mean score in the erectile function domain of the International Index for Erectile Function (IIEF-EF) significantly increased after the 6-week treatment (15.8±3.7 to 19.9±3.8; p<0.001).
For group A, scores after 1 month, 3 months and 6 months were 19.5, 19.0 and 19.3 points, respectively, indicating significant improvements from the 16.2 score at baseline (p<0.001). The respective improvements in group B were greater (20.6, 20.6 and 20.5 points; p<0.001).
At 6 months, group B had significantly better outcomes in the Sexual Encounter Profile than group A. Compared to 47 percent in group A, 65 percent in group B affirmed that their erections lasted long enough for successful intercourse. The between-group difference reached significance (p=0.02).
Retreatment with the six additional sessions resulted in further significant improvements in IIEF-EF scores. Scores increased from 20.3±3.5 points at baseline to 22.1±4.3 points at the 6-month follow-up after the six additional sessions (p<0.001).
