Summary

Story summary

A study from the University of California, Riverside confirms that paternal exposure to microplastics before breeding causes metabolic dysfunction in offspring.
Female offspring develop insulin resistance when fed a high-fat diet.
Male offspring show metabolic changes.
The study identifies over 4,000 alterations in sperm RNA, suggesting these changes influence embryonic gene expression and intergenerational health.
