Safety and efficacy evaluation of intracavernosal injection of platelets rich plasma in treatment of vasculogenic erectile dysfunction.

Abstract

Objectives: The study's objective is to compare platelet-rich plasma (PRP) injections to placebo in terms of effectiveness and safety for patients with vasculogenic erectile dysfunction (ED).

Methods: This randomized placebo-controlled clinical trial was done on 50 male patients with organic vasculogenic ED and sexually active in a stable heterosexual relationship for a period of over three months. The patients were randomized into two main groups: Group (A) (n = 25) underwent PRP treatment. Group (B) (n = 25) control underwent placebo treatment.

Results: The two groups under study differed in a statistically significant way regarding the achievement of minimal clinically important differences (MCID) at 3 months and 24 months. Statistically significant variations existed between the mild subgroup and placebo regarding achieving MCID after 3 months and 24 months. The level of satisfaction was statistically significantly higher in the PRP group. A statistically significant variation was present between the mild subgroup and placebo at 3 months and 24 months in terms of changes from baseline in the erectile function domain of the International Index of Erectile Function (IIEF-EF) questionnaire score in each subgroup.

Conclusions: PRP is an effective alternative modality of treatment in cases of ED, and they offer an intermediate stage between pharmaceutical therapy and surgical interventions at least in mild and mild to moderate cases where unsatisfactory results or unpleasant side effects compel the patients to abandon all hope on medical treatment.
