ClearUnderstanding the impact of nanoplastics on reproductive health: Exposure pathways, mechanisms, and implications
This review summarizes existing research on how nanoplastics (tiny plastic particles smaller than one micrometer) affect reproductive health in animals and potentially humans. Studies show that nanoplastics can accumulate in reproductive organs including the placenta, and evidence from animal studies links exposure to hormone disruption, reduced fertility, and developmental problems. The authors highlight a significant knowledge gap about nanoplastic effects on human reproduction, despite growing evidence that these particles reach our reproductive systems.
Adverse effects of microplastics and nanoplastics on the reproductive system: A comprehensive review of fertility and potential harmful interactions
This review summarizes how microplastics and nanoplastics can harm both male and female reproductive systems by disrupting hormone signaling, damaging sperm and egg cells, and causing inflammation in reproductive tissues. Smaller nanoplastics are especially concerning because they can cross biological barriers more easily and reach the testes and ovaries. With global infertility rates rising, the authors highlight environmental plastic exposure as a factor that deserves more research attention.
