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.
