Nano and microplastics (NMPS) impair meiosis and alter the redox state of the mouse female germ cell

Impact and mechanisms of microplastics and nanoplastics on the reproductive system

AI summary · Read the abstract

Researchers reviewed evidence that microplastics and nanoplastics disrupt both male and female reproductive systems across multiple species, causing oxidative stress, endocrine disruption, reduced sperm quality, impaired ovarian function, and potentially transgenerational reproductive damage — with human data still limited but concerns growing.

Microplastics and nanoplastics: Emerging threats to female reproductive health and developmental outcomes

AI summary · Read the abstract

Researchers reviewed the effects of microplastics and nanoplastics on female reproductive health, finding that these particles accumulate in reproductive organs and are linked to oxidative stress, hormonal disruption, DNA damage, and impaired oocyte and embryo development, with potential cross-generational impacts on offspring health.

Microplastics and nanoplastics in human health: a comprehensive review of exposure pathways, cellular mechanisms, and toxicological implications

AI summary · Read the abstract

Researchers reviewed human exposure pathways to microplastics and nanoplastics through seafood, salt, drinking water, inhalation, and skin contact, examining how these particles cross biological barriers to reach organs and trigger oxidative stress, inflammation, and endocrine disruption with poorly understood long-term consequences.

Molecular mechanisms of microplastics toxicity

The toxicity of polyethylene microplastics on molecular and biochemical parameters in albino mice

AI summary · Read the abstract

Researchers assessed the molecular and biochemical effects of polyethylene microplastic exposure in albino mice, finding dose-dependent toxicity across multiple organ systems, with measurable alterations in liver enzymes, oxidative stress markers, and blood cell parameters consistent with systemic health impacts.
