Erectile Function Recovery Using Shockwave and Platelet-Rich Plasma: A Single-Centre Prospective Comparative Study

The study aimed to analyse the comparative effect of low-intensity extracorporeal shockwave therapy (Li-ESWT), platelet-rich plasma (PRP), and their combination for treating arteriogenic erectile dysfunction (ED).

This prospective observational study involved men diagnosed with arteriogenic ED over six months. Four hundred men aged 35-65 with ED, diagnosed using the International Index of Erectile Function (IIEF-5) and penile colour Doppler ultrasonography (USG), joined the research. The participants were divided into four groups: Li-ESWT, PRP, Li-ESWT + PRP, and Control. Outcomes were assessed at baseline and at one, three and six months post-treatment, focusing on changes in IIEF-5 scores and penile haemodynamics, including peak systolic velocity (PSV) and end-diastolic velocity (EDV).

Li-ESWT significantly improved IIEF-5 scores from baseline to three months (p = 0.001), with sustained but reduced effects at six months (p = 0.001). PRP alone showed mild improvement at one month (p = 0.028), with no significant effect persisting at six months (p = 0.119). Combination therapy demonstrated the most pronounced and sustained improvement in IIEF-5 scores, particularly at three and six months (p = 0.001). Haemodynamic analysis revealed a significant increase in PSV at three months in the Li-ESWT and combination groups (p = 0.001) with mild regression at six months (p = 0.003). EDV changes were negligible across all groups and time points (p > 0.05).

Combining Li-ESWT and PRP provided the most substantial and sustained improvement in erectile function and arterial haemodynamics. While Li-ESWT demonstrated notable efficacy, PRP alone showed limited and transient benefits.
