In a nutshell
This study evaluated the effectiveness and safety of platelet-rich plasma (PRP) injections for the treatment of patients with mild and moderate erectile dysfunction (ED). The data showed that PRP was a safe and promising treatment for improving mild to moderate ED.
Some background
Erectile dysfunction (ED) consists of the inability to get and keep an erection firm enough for sexual intercourse. This has a negative impact on the quality of life of men. The standard primary treatment is with phosphodiesterase-5 (PDE5) inhibitors. PDE5 inhibitor such as tadalafil (Cialis) has been shown to improve ED symptoms by increasing the blood flow to the penis and helping to maintain an erection. However, a significant number of these patients still do not manage to have satisfactory intercourse despite treatment with these medications.
Platelet-rich plasma (PRP) therapy is a newer therapy based on injecting a portion of the patient’s blood. PRP contains a variety of growth factors that promote tissue repair. However, the effectiveness and safety of PRP for the treatment of patients with mild to moderate ED are still unknown.
Methods & findings
This study involved 100 patients with mild to moderate ED. Patients were randomly assigned into 2 groups. Group 1 included 50 patients who received treatment with PRP injections into the penis. Group 2 included 50 patients who received treatment with saline injections (placebo). The patients were followed up at 1, 3, and 6 months.
Erectile function was evaluated through a standardized International Index of Erectile Function domain (IIEF-EF) questionnaire. Patients were also evaluated using the Minimal Clinically Important Difference (MCID). MCID is defined as the smallest change in an outcome that a patient would perceive as clinically meaningful.
After 1 month of follow-up, the average IIEF scores significantly improved in 76% of the patients in group 1 as they achieved an MCID compared to 18% of the patients in group 2.
After 3 months of follow-up, the average IIEF scores significantly improved in 72% of the patients in group 1 as they achieved an MCID compared to 16% of the patients in group 2.
After 6 months of follow-up, the average IIEF scores significantly improved in 70% of the patients in group 1 as they achieved an MCID compared to 16% of the patients in group 2.
The overall and intercourse satisfaction levels of the patients were higher in group 1 than in group 2.
There were no major side effects reported in either group.
The bottom line
This study concluded that PRP was a safe and promising treatment for improving mild to moderate ED.
The fine print
The sample size was very small and the follow-up period was short. This study only included patients treated at a single institution in Egypt. Larger studies with longer follow-up periods are needed.
