Review of PFAS exposure links to reproductive dysfunction in assisted reproductive technology

This narrative review focuses on the relationship between per- and polyfluoroalkyl substances (PFAS) exposure and reproductive dysfunction in individuals undergoing assisted reproductive technology (ART). The scope of the publication is to provide updated perspectives for researchers and public health policymakers regarding this emerging area of concern.

Current evidence indicates that PFAS may be associated with diminished fertility, adverse pregnancy outcomes, and impaired fetal health. The review does not report specific effect sizes, absolute numbers, or p-values for these associations. The direction of the association is noted without statistical quantification in this source.

The authors acknowledge that underlying mechanisms remain incompletely elucidated. This limitation suggests that the biological pathways linking PFAS exposure to these reproductive outcomes are not yet fully understood. Consequently, the review avoids definitive causal language and frames findings as associations based on available data.

The practice relevance is directed toward researchers and policymakers rather than immediate clinical management of individual patients. The review highlights the need for further investigation into the mechanisms of PFAS toxicity in the context of ART.
