This study’s findings demonstrate that combination treatment of low-intensity shock wave therapy (Li-SWT) with platelet-rich plasma (PRP) injections is not only safe for individuals with erectile dysfunction (ED) but also effective and safe in prolonging the intravaginal ejaculatory latency time (IELT).
This study included 93 patients who were subjected to Li-SWT only (Group 1) and 91 patients subjected to Li-SWT with PRP (Group 2).
It was shown that the analysis of the International Index of Erectile Function-Erectile Function Area (IIEF-EF) scores demonstrated a significant increase in both the groups post-treatment (Group 1: from 14.33 ± 4.39 to 23.8 ± 4.37, p = .001; Group 2: from 17.82 ± 3.44 to 26.3 ± 2.55, p = .001).
No statistically significant difference was found between them when the increase in the IIEF-EF scores was compared pre-and post-treatment between the groups concerning the ED grades.
Moreover, Group 2 presented 1.5–3.5 times (mean, 2.4) prolongation, while the intravaginal ejaculatory latency time (IELT) in successfully treated patients of Group 1 remained the same.
In addition, their mean IELT score indicated an increase from 2.2 (0.8–3.5) min to 5.3 (2.8–10.5) min.
