Reproductive Toxicity of Per- and Polyfluoroalkyl Substances

Ajana, Robinson, Rachoń, Dominik, Gałęzowska, Grażyna·2025·Environmental Toxicology and Pharmacology

Abstract

Per- and polyfluoroalkyl substances (PFAS) are synthetic fluorinated compounds known for their persistence in the environment and widespread presence in consumer products. Human exposure occurs through multiple routes, leading to bioaccumulation in various tissues and significant health concerns, particularly reproductive toxicity. This review critically examines the reproductive effects of both long- and short-chain PFAS and explores the mechanisms underlying their toxicity. PFAS have been shown to downregulate key genes involved in steroidogenesis, including steroidogenic acute regulatory protein (StAR), cytochrome P450 enzymes (CYP11A1, CYP17A1), 3β-hydroxysteroid dehydrogenase, and 17β-hydroxysteroid dehydrogenase. Additionally, PFAS exert direct toxic effects on developing spermatogonia and oocytes, impairing reproductive function. While most research has focused on long-chain PFAS, this review highlights that short-chain PFAS pose comparable risks, necessitating further investigation. The ability to biodegrade PFAS has been demonstrated, offering a potential approach to mitigate tissue accumulation and reduce associated health risks. However, gaps remain in our understanding of PFAS mechanisms, with conflicting evidence across different compounds and study models. Standardized methodologies and long-term human studies are essential to fully elucidate the chronic effects of PFAS exposure and develop effective mitigation strategies.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • PFASs suppress expression of critical genes involved in steroid hormone biosynthesis (StAR, CYP11A1, CYP17A1, 3β- and 17β-hydroxysteroid dehydrogenases).

    “Per- and polyfluoroalkyl substances have been found to suppress the expression of critical genes involved in steroid hormone biosynthesis, such as the steroidogenic acute regulatory protein, several cytochrome P450 enzymes (CYP11A1, CYP17A1), and 3β- and 17β-hydroxysteroid dehydrogenases.”
  • PFASs can directly damage developing germ cells-including spermatogonia and oocytes-potentially compromising reproductive capacity.

    “Furthermore, PFASs can directly damage developing germ cells—including spermatogonia and oocytes—thereby potentially compromising reproductive capacity [90].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
