Per- and polyfluoroalkyl substances (PFAS) and fetal growth: A nation-wide register-based study on PFAS in drinking water
Science
8 May 2024 | Environ Int
A nationwide study in Sweden found no clear link between maternal exposure to certain PFAS during pregnancy and newborn birthweight or risk of being small-for-gestational-age, but did find a slight increase in the risk of being large-for-gestational-age, particularly associated with PFOS.

Sub-acute exposure of male guppies (Poecilia reticulata) to environmentally relevant concentrations of PFOA and GenX induces significant changes in the testis transcriptome and reproductive traits
Science
26 Apr 2024 | Environ Int
Exposure of male guppies to environmentally realistic levels of a legacy PFAS and its replacement compound (GenX) resulted in altered reproductive traits, including changes in sexual behavior and sperm motility, as well as gene expression related to immune regulation. These changes highlight the potential adverse effects of PFAS on behavior, fertility, and immunity in fish populations.
