Platelet-Rich Plasma With or Without Tadalafil for Erectile Dysfunction

Sponsor: Benha University

Summary

Platelet-rich plasma is being studied as a regenerative treatment option for erectile dysfunction, but it is unclear whether adding daily tadalafil gives additional benefit over platelet-rich plasma alone. This study evaluates adult men with mild to mild-moderate erectile dysfunction who had an inadequate response to previous phosphodiesterase type 5 inhibitor treatment. Participants were randomly assigned to receive either intracavernosal platelet-rich plasma injections combined with oral tadalafil 5 milligrams once daily, or intracavernosal platelet-rich plasma injections alone. The platelet-rich plasma injection protocol consisted of three intracavernosal treatment sessions spaced two weeks apart. Erectile function was assessed using the International Index of Erectile Function-5 questionnaire at baseline and during follow-up at 1, 3, and 6 months. Penile duplex Doppler ultrasound was performed at baseline and after 6 months to assess erectile blood-flow parameters. The study hypothesis is that adding daily tadalafil to intracavernosal platelet-rich plasma may produce greater improvement in patient-reported erectile function compared with platelet-rich plasma alone, while also allowing assessment of whether this improvement is accompanied by measurable changes in penile Doppler parameters. The study included 156 participants in the final analysis, with 78 participants in each treatment group.
