Level 5 - mechanism / opinion, no new human data
Narrative review summarizing mechanistic and observational literature without systematic review methodology or new human data.

What was done
The authors reviewed literature on the effects of legacy, alternative, and short-chain per- and poly-fluoroalkyl substances (PFAS) and PFAS mixtures on female reproductive health. The review synthesized evidence on endocrine disruption, impacts on the hypothalamic-pituitary-gonadal axis, thyroid, and breast tissue, as well as downstream effects on hormone secretion, menstrual cyclicity, and fertility.
What was found
The abstract reports no numerical data or quantitative effect sizes. It qualitatively describes findings that long- and short-chain PFAS disrupt female reproductive function by altering hormone secretion, menstrual cyclicity, and fertility via direct tissue effects and indirect endocrine disruption.
Why it matters
This review highlights how widespread environmental PFAS exposures may contribute to declining female fecundity and reproductive disorders via endocrine disruption.
Limits
The abstract describes a narrative review without meta-analysis, systematic methodology, or quantitative data. Precise molecular targets and mechanisms of action in female reproductive tissues remain unestablished.
