Abstract

BACKGROUND: Animal studies postulate that platelet-rich plasma (PRP) injections improve key elements of the pathophysiologic mechanisms leading to erectile dysfunction (ED). AIM: To conduct the first double-blind, randomized, placebo-controlled trial assessing the efficacy and safety of PRP injections in patients with mild and moderate ED. METHODS: Sixty sexually active patients with mild and moderate ED were randomly assigned to two sessions, with a one-month difference, of 10 mL PRP (n = 30) or placebo (n = 30) intracavernosal injections. An FDA-approved separation system was used. Patients were evaluated at 1, 3 and 6 months after completion of the treatment protocol. A per-protocol analysis was applied. All participants withheld any ED treatment during the trial. OUTCOMES: The achievement of minimal clinically important difference (MCID) in the International Index of Erectile Function - Erectile Domain (IIEF-EF) from baseline to 6 months after final treatment. Erectile function at all time points, as well as safety of PRP injections, were also evaluated. RESULTS: At 6 months, a MCID was achieved by 20/29 (69%) patients in the PRP group compared to 7/26 (27%) in the placebo group. The risk difference between the two groups was 42% (95%CI: 18-66), P < 0.001 and the baseline-adjusted mean between-group-difference in the IIEF-EF score was 3.9 points (95%CI: 1.8-5.9). Similarly, a statistically significant difference of both the number of participants attaining a MCID and the IIEF-EF score was also observed at the 1- and 3-month evaluation between the two groups. Accordingly, patients receiving PRP were more satisfied with the treatment. No adverse events were observed during the study period. CLINICAL IMPLICATIONS: Intracavernosal PRP injection therapy used as outlined in this trial appears to be a safe and effective short-term treatment for the management of mild to moderate ED. STRENGTHS & LIMITATIONS: We conducted the first clinical trial exploring the role of PRP in the management of ED. Conversely, our findings lack external validity due to single-center design. Furthermore, our results cannot be extrapolated to other PRP separation systems. CONCLUSIONS: PRP intracavernosal injections may be a promising addition to the urologist's armamentarium for the management of ED. Still, further high-quality studies are warranted to corroborate our findings. Evangelos P, Mykoniatis I, Pyrgidis N, et al.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
