flag A new Australian study links low-level PFAS exposure to hormonal disruption, reduced sperm counts, and abnormal gene expression in mice, raising concerns about human fertility and generational health.

flag A new Australian study finds that short-term exposure to real-world levels of a mixture of PFAS chemicals—commonly found in water—disrupts hormones, reduces sperm counts in male mice, and causes abnormal gene expression in embryos, even when offspring aren’t directly exposed. flag The research, using a PFAS mix from a contaminated site including PFOS, PFHxS, and PFOA, revealed hormonal changes and fertility issues at low doses, suggesting non-linear effects typical of endocrine disruptors. flag Findings support concerns about PFAS impacting human fertility and future generations, with nearly all Australians having detectable levels of these chemicals. flag The study was funded by NHMRC and has implications for human and wildlife health.
