A Phase 2 Randomized, Placebo-controlled Crossover Trial to Evaluate Safety and Efficacy of Platelet-rich Plasma Injections for Peyronie's Disease: Clinical Trial Update

European Association of Urology Guidelines on Male Sexual and Reproductive Health: 2025 Update on Male Hypogonadism, Erectile Dysfunction, Premature Ejaculation, and Peyronie's Disease

OBJECTIVE

The objective of this study is to present a summary of the updated 2025 European Association of Urology (EAU) guidelines on sexual and reproductive health (SRH), focusing on hypogonadism, erectile dysfunction (ED), premature ejaculation (PE), and Peyronie's disease (PD), providing practical recommendations on the clinical workup, with a focus on diagnosis, treatment, and follow-up.

EVIDENCE ACQUISITION

The panel conducted an updated systematic review of new research published in 2021-2024 in Medline, EMBASE, and Cochrane Libraries. The guidelines' recommendations focused on key clinical decisions that would impact patient care most. Each recommendation's strength was evaluated based on three factors: the trade-offs between benefits and drawbacks of different treatment approaches, the quality and reliability of the available evidence, and the diverse preferences and values of patients.

KEY FINDINGS

Along with a detailed basic and advanced diagnostic approach for every condition, key recommendations emphasise the importance of appropriate indications and subsequent follow-up for testosterone therapy in patients with late-onset hypogonadism (LOH), a clinical condition in the ageing male combining low levels of circulating testosterone and specific symptoms associated with impaired hormone production and/or action. The decision-making algorithm for treating ED-defined as the persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance-aims to support personalised treatment tailored to individual patients, according to the invasiveness, tolerability, and effectiveness of the different therapeutic options and patients' expectations. Hence, patients should be fully counselled with respect to all available treatment modalities. The EAU guidelines adopted the definition of PE, which has been developed by the International Society for Sexual Medicine. After the subtype of PE has been defined, patient's expectations should be discussed thoroughly, and pharmacotherapy must be considered as the first-line treatment for patients with lifelong PE, whereas treating the underlying cause must be the initial goal for patients with acquired PE. An accurate baseline assessment of patients with PD should differentiate between acute and stable phases of the disorder. Surgical treatment for PD should be offered to patients having a penile deformity with a negative impact on sexual function: patients with concomitant ED should be offered penile prosthesis implantation.

CONCLUSIONS AND CLINICAL IMPLICATIONS

This overview of the 2025 EAU SRH guidelines offers valuable insights into the diagnosis, treatment, and follow-up of LOH, ED, PE, and PD.

Evidence of restorative therapies in the treatment of Peyronie disease: A narrative review

OBJECTIVE

To describe the evidence of Platelet Rich Plasma (PRP), Stem cells therapy (SCT) and Extracorporeal shockwave therapy (ESWL) for the treatment of Peyronies disease (PD), including information from the main urological society guidelines.

MATERIALS AND METHODS

A literature review of PubMed articles published between 2000 and 2023 was conducted, utilizing keywords such as "Peyronie's Disease", "Penile curvature", "Platelet Rich Plasma", "Stem cells", and "Extracorporeal shockwave therapy". Only full-text articles in English were included, excluding case reports and opinions.

RESULTS

A considerable number of clinical trials were conducted using PRP penile injections for therapy of PD, showing reduction of curvature, plaque size and improvement in quality of life. Preclinical studies in rats have shown the potential benefit of adipose-derived stem cells, with improvements in erectile function and fibrosis. Human studies with mesenchymal stem cells demonstrated promising results, with reduction of curvature and plaque size. ESWL effects on PD were investigated in randomized clinical trials and demonstrated no significant impact in curvature or plaque size, but reasonable effect on pain control.

CONCLUSION

Restorative therapies has emerged as an innovative treatment option for PD and the results from current studies appear to be promising and demonstrated good safety profile. Unfortunately, due to scarce evidence, PRP and SCT are still considered experimental by American Urological Association (AUA) and European Association of Urology (EAU) guidelines. ESWT is recommended, by the same guidelines, for pain control only. More high-quality studies with long-term follow-up outcomes are needed to evaluate efficacy and reproducibility of those therapies.

Platelet-rich plasma therapy in erectile dysfunction and Peyronie's disease: a systematic review of the literature

PURPOSE

Platelet-rich plasma (PRP) as a regenerative therapy has gained interest in the field of andrology for the treatment of erectile dysfunction (ED) and Peyronie's disease (PD). This systematic review aims to critically evaluate the current evidence on the use of PRP for these conditions.

METHODS

We performed a systematic literature search according to the PRISMA guidelines using PubMed and Scopus databases in December 2023. Studies were included if they evaluated the effect of PRP therapy for ED or PD in humans.

RESULTS

We identified 164 articles, 17 of which were included, consisting of 11 studies on ED, 5 studies on PD, and 1 study on both. We included four randomized controlled trials, 11 prospective cohort studies, and three retrospective cohort studies including a total of 1099 patients. The studies on ED and PD generally showed small to moderate benefits with mild and transient side effects and no major adverse events were reported. General limitations included variations in PRP protocols, small sample sizes, short follow-up periods, and lack of control groups except in the three randomized trials on ED and the one on PD.

CONCLUSION

The literature on PRP therapy in andrology is limited and difficult to interpret due to variations in protocols and methodological drawbacks. Further research is necessary to determine the optimal preparation and treatment protocols for PRP therapy and clarify its effectiveness in andrology.

Stem-Cell, Shockwave, and Platelet Rich Plasma Therapy for the Treatment of Erectile Dysfunction and Peyronie's Disease: A Survey of Clinics Across the USA

OBJECTIVE

To identify clinics offering off-label therapies for erectile dysfunction (ED) and Peyronie's disease (Pyd) including stem cell, platelet-rich plasma (PRP), and shockwave therapy and to determine the transparency they provided to patients inquiring about these treatment modalities.

METHODS

Clinics were identified in different regions in the US using a systematic search on online website directories and were approached by asking a series of standardized questions regarding the cost of treatment, duration of therapy, the medical staff involved, and patient outcome data. A total of 26 clinics were surveyed for stem cell therapy, 26 for PRP treatment, and 27 for shockwave therapy.

RESULTS

Of the 79 clinics contacted, 93.7% provided some answers to the questions we asked, with a majority offering treatments for both ED and Pyd. The cost of treatment varied widely between clinics. The average cost per stem cell therapy injection was $5291, PRP per injection was $1336, and shockwave therapy per session was $413. A physician was involved in 67% of treatments, and only 6 of 79 clinics reported that a urologist was involved. Over 75% of the clinics reported patient satisfaction following treatment. Durability of benefits to patients ranged from months to years according to the clinics' reports.

CONCLUSION

Our data not only demonstrate the widespread use of off-label therapies for ED and PyD across the United States but also the lack of scientific data to support the claims made to patients. This study highlights the need for more oversight and standardization in novel regenerative therapies for ED and PyD.
