Fertility Impact of Microplastics - Advancing Countermeasures and Tracking (FERTIMPACT)

Although the presence of MNPs in the human body, including reproductive fluids and placental tissue, has recently been documented, their health implications remain poorly understood, particularly in the context of the function of the human reproductive system. FERTIMPACT is the first project to systematically investigate the links between MNP exposure and reproductive toxicity by leveraging Machine Learning (ML) and multi-omics, while also exploring transgenerational effects, enabling real-time risk prediction and tracking through an integrated AI-driven platform, and developing evidence-based countermeasures and policy tools for exposure reduction. The project introduces several innovative and ground-breaking elements, derived from several diagnostic needs, including an integrated methodological approach that combines state-of-the-art label-free spectroscopic imaging techniques, thermo-analytical tools, advanced particle characterization methods and multiparametric graphene-based biosensing at the point of care for comprehensive exposure assessment in the human body and environment; a novel conceptual framework linking environmental contamination to reproductive dysfunction via shared molecular mechanisms such as oxidative stress, endocrine disruption, and genotoxicity; an AI-powered Environmental Health Intelligence Platform capable of integrating environmental and health data to dynamically assess exposure-health relationships and generate real-time risk maps; and a transdisciplinary approach bridging lab-based science with public health action through environmental monitoring, clinical research, AI, and regulatory science. Crucially, FERTIMPACT emphasizes co-development of policy recommendations and mitigation strategies with stakeholders to ensure meaningful real-world impact and uptake. Preliminary patent and publication searches indicate no prior integrated platform that combines real-world biomonitoring, mechanistic analysis, and predictive modeling of MNPs reproductive risks at this scale. Recent publication form the scientific foundation, but FERTIMPACT will extend these findings into actionable health interventions.

Although the present study is non-interventional, it is based on a biologically plausible hypothesis supported by emerging experimental and translational evidence. Micro- and nanoplastics (MNPs) have been shown to induce oxidative stress, leading to the generation of reactive oxygen species and disruption of cellular homeostasis, which may impair gamete quality and reproductive function. In addition, MNPs can act as carriers of endocrine-disrupting chemicals, potentially interfering with hormonal regulation critical for reproductive processes. Experimental studies have also demonstrated genotoxic effects, including DNA damage and chromosomal instability, which may affect fertility and early embryonic development. These mechanisms provide a strong biological rationale for investigating the association between MNP exposure and reproductive outcomes in human populations. However, clinical evidence in humans remains limited, particularly in well-defined reproductive cohorts, justifying the need for the proposed prospective clinical study.
