Fiocruz Brasília and UnDF Forge Partnership for PMMA Penile Filler Research
In a significant development for public health research in Brazil, Fiocruz Brasília, a leading biomedical research institute under the Oswaldo Cruz Foundation (Fundação Oswaldo Cruz, or Fiocruz), has partnered with the Universidade do Distrito Federal (UnDF). This collaboration, formalized through Technical Cooperation Agreement No. 25/2025 on April 30, 2025, and published in the Official Gazette of the Federal District, aims to advance scientific research and medical training focused on sanitary surveillance and regulation. The initiative responds directly to a demand from Brazil's National Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, or Anvisa) to investigate the safety of polymethylmethacrylate (PMMA), a synthetic filler material used in certain medical procedures.
The partnership emphasizes integrated efforts in teaching, research, and extension services, aligning with the principles of Brazil's Unified Health System (Sistema Único de Saúde, or SUS). Funded by Anvisa's project "Support for Actions to Develop Regulation and Sanitary Surveillance," it marks a crucial step in generating evidence-based knowledge to inform health policies and practices.
Background on PMMA Use in Penile Augmentation Procedures
Polymethylmethacrylate (PMMA) is a biocompatible, permanent filler approved by Anvisa primarily for reparative purposes, such as correcting lipodystrophy in HIV patients. However, its off-label use in aesthetic procedures, particularly penile girth enhancement (preenchimento peniano), has surged in popularity despite significant safety concerns. Penile fillers like PMMA are injected to increase circumference, appealing to men seeking non-surgical augmentation for perceived inadequacies or cosmetic reasons.
Brazilian plastic surgery societies, including the Brazilian Society of Plastic Surgery (Sociedade Brasileira de Cirurgia Plástica, or SBCP), and the Federal Council of Medicine (Conselho Federal de Medicina, or CFM) have repeatedly warned against PMMA's aesthetic applications. Reports highlight risks including chronic inflammation, granulomas, infections, material migration, penile deformity, and even necrosis requiring reconstructive surgery. Anvisa's March 2026 alert reiterated that fillers must be used strictly within approved indications, volumes, and anatomical sites to avoid irreversible harm.
Despite these cautions, demand persists, often driven by unqualified practitioners. This underscores the urgent need for rigorous scientific evaluation, which the Fiocruz-UnDF partnership addresses head-on.
Anvisa's Call for Evidence Spurs Collaborative Research
The research originated from Anvisa's specific request for data on PMMA's safety as an intradermal filler and implant in reparative plastic surgeries. This evolved into a targeted systematic review on PMMA for penile enlargement, examining clinical outcomes, adverse events, and long-term efficacy. Coordinated by Flávia Elias from Fiocruz Brasília's Policy, Economics, Procurement, and Strategic Management Support Center (Pepts) and Erika Camargo from UnDF, the study compiles global and Brazilian evidence to guide regulatory decisions.
In its first year, the team produced a manuscript submitted to an international peer-reviewed journal. This review synthesizes existing literature on PMMA's biocompatibility, injection techniques, complication rates, and reversibility challenges. Preliminary insights highlight variability in outcomes based on dilution (e.g., 30% PMMA mixtures), provider expertise, and patient factors like immune status. While some international studies report low adverse event rates (under 5% for gluteal fillers), penile applications show higher risks due to vascularity and mobility.
The collaboration exemplifies how regulatory needs can drive academic research, positioning Brazilian institutions as contributors to global health technology assessment.
UnDF Medical Students Gain Hands-On Research Experience
A cornerstone of the partnership is the practical involvement of four UnDF medical students in the PMMA study. This immersion bridges classroom theory with real-world application, fostering skills in systematic literature reviews, data synthesis, and critical appraisal—essential for evidence-based medicine. Students contribute to protocol design, article screening, and manuscript drafting under mentor supervision, embodying Fiocruz's commitment to early-career research training.
UnDF, as Brasília's public university, benefits from Fiocruz's expertise in public health research. This model integrates higher education with SUS priorities, preparing future physicians for roles in regulatory science and clinical decision-making. Participants report enhanced understanding of sanitary surveillance, emphasizing multidisciplinary approaches to cosmetic procedure risks.
Addressing Gaps in Medical Training for Aesthetic Procedures
Brazilian medical curricula often underemphasize aesthetic medicine training, particularly high-risk interventions like penile fillers. The partnership plans 2026 extension courses for UnDF undergraduates, covering scientific methods, critical thinking, and PMMA-specific protocols. These short programs aim to equip students with tools for evaluating unapproved uses, promoting ethical practice and patient safety.
- Core modules: Systematic review methodologies and GRADE evidence assessment.
- Practical components: Case simulations of PMMA complications.
- Outcomes: Certificates enhancing CVs for SUS residencies.
This initiative counters informal training prevalent in aesthetics, where non-specialists perform procedures, amplifying risks. By embedding research in training, it cultivates a generation of urologists and plastic surgeons versed in pharmacovigilance.

Reported Risks and Complications of PMMA Penile Fillers
Existing data paints a cautionary picture. Brazilian case reports document late-onset granulomatous reactions, erectile dysfunction, and penile shortening post-PMMA injection. A 2025 integrative review analyzed 587 complications, noting inflammation (42%), migration (28%), and infections (15%). International studies on mixtures like Lipen-10 (PMMA-dextran) report 2-10% major events, but penile-specific data is sparse and biased toward favorable outcomes from proponents.
Anvisa's stance: PMMA is Class III device for small-volume reparative use only. Off-label penile volumes (10-30ml) exceed approvals, risking embolism and autoimmunity. Proper training mitigates but doesn't eliminate hazards; ultrasound guidance and sterile techniques are mandated yet inconsistently applied.
| Complication | Incidence (Reported) | Severity |
|---|---|---|
| Granulomas | 20-40% | High (surgical excision) |
| Infection | 5-15% | Medium-High |
| Migration/Deformity | 10-30% | High |
| Necrosis | 1-5% | Critical |
The Fiocruz study promises unbiased synthesis, potentially informing Anvisa restrictions.
Implications for Public Health Regulation in Brazil
Brazil leads Latin America in cosmetic surgeries (1.5 million/year), with penile augmentation rising amid social media influence. Unregulated clinics exacerbate harms, straining SUS resources for revisions. Fiocruz's review could catalyze PMMA reclassification, mandating training certification and volume caps.

Stakeholders: SBCP advocates hyaluronic acid alternatives (reversible, lower risk). Urologists stress psychological counseling pre-procedure, as 70% dissatisfaction ties to body dysmorphia.
Broader Impact on Brazilian Higher Education and Research
This partnership exemplifies Fiocruz's role in bridging research institutes and universities, vital for Brazil's 200+ public universities facing funding cuts. UnDF gains prestige, attracting SUS-aligned talent. Nationally, it models integration amid CAPES graduate program reforms emphasizing applied health research. Ties to /higher-education-news/peer-academic-leadership-academy-or-1-pal-program-or-academicjobs-19683 highlight retention strategies via such collaborations.
Statistics: Brazil produces 200,000 health graduates yearly, yet 40% lack research exposure. Initiatives like this boost employability in regulatory bodies like Anvisa (1,200 staff trained by Fiocruz historically).
Future Outlook: Extension Courses and Ongoing Studies
2026 priorities: Launch extension courses for 50+ UnDF students, piloting PMMA workshops. Long-term: Prospective cohort tracking PMMA patients, pharmacokinetics modeling. Global dissemination via publications positions Brazil in aesthetic medicine discourse. Experts foresee training mandates if safety thresholds unmet.
