Researchers used multi-omics analysis to study the effects of long-term polystyrene nanoplastic exposure on mouse testes and found signs of premature testicular aging. The damage was dependent on both the age of the mice and the duration of exposure, with younger animals showing particular vulnerability. The study suggests that protecting mRNA metabolism and testosterone production could help preserve reproductive function in males exposed to nanoplastics.
Integrated with multi-omics analyses, our study collectively extends the current understanding of PS-NP-induced testicular and sperm toxicology, highlighting age- and duration-dependent risks to male reproduction. Protecting mRNA metabolism and testosterone production may help preserve reproductive capacity in young males exposed to NPs.
