This study found that PRP injections may safely improve penile curvature and PDQ scores in men with stable-phase Peyronie's Disease, although the curvature reduction observed was not enough to determine long-term clinical significance.
January 2026 in “Andrology” This study found that PRP injections are safe and may slightly reduce penile curvature and improve PDQ scores in men with stable-phase Peyronie's Disease, but the changes are not significant enough to predict long-term effects.
This study evaluated the effect of intralesional injections of lyophilized Platelet Derived Growth Factors in 42 patients with Peyronie's disease and found significant reductions in penile curvature and plaque size, along with improvements in Peyronie's Disease Questionnaire scores, suggesting a potential treatment role.
