Effects of nano and microplastics on the reproduction system: In vitro and in vivo studies review
Summary
This review summarizes both lab and animal studies on how micro and nanoplastics affect the reproductive system in males and females. Evidence shows that microplastics can reduce sperm quality, damage ovaries, disrupt hormone levels, and even cross the placenta during pregnancy. The findings raise significant concerns about how widespread microplastic exposure might contribute to fertility problems and reproductive health issues in humans.
Microplastics (MPs) and nanoplastics (NPs), as their name suggest, are tiny plastic particles. The negative impact of MPs as an emerging pollutant on humans is not hidden from anyone. Recent research on how this pollutant affects the reproductive system and how it enters the blood, placenta, and semen has attracted the attention of scientists. This review study deals with the reproductive toxicity of MPs particles in terrestrial animals, aquatic animals, soil fauna, human cells, and human placenta. In vitro and in vivo animal studies showed that MPs can lead to reduced fertility in men, reduced ovarian capacity, apoptosis of granulosa cells, or even reduced sperm motility. They cause oxidative stress and cell apoptosis and inflammatory effects. The results of these animal studies show that MPs may have similar effects on the human reproductive system. However, not much research has been done on human reproductive toxicity by MPs. Therefore, special attention should be paid to the toxicity of the reproductive system by MPs. The purpose of this comprehensive study is to express the importance of the impact of MPs on the reproductive system. These results provide new insight into the potential dangers of MPs.

Effects of micro(nano)plastics on the reproductive system: A review
This review summarizes research on how micro and nanoplastics affect the reproductive system in both animal studies and cell experiments. Evidence indicates these particles can cross biological barriers, accumulate in reproductive organs, and disrupt hormones, egg development, and sperm quality. While human studies are still limited, the animal data suggests microplastic exposure may be a meaningful concern for reproductive health.
Unraveling the threat: Microplastics and nano-plastics' impact on reproductive viability across ecosystems
This review summarizes research on how microplastics and nanoplastics affect reproduction across many species, from aquatic invertebrates to mammals including humans. In males, exposure leads to testicular damage, lower sperm quality, and hormone disruption; in females, it causes ovarian and uterine problems, inflammation, and reduced fertility. The evidence also shows these reproductive harms can be passed to offspring, raising serious concerns about long-term effects on human fertility.
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.
Toxicological effects of micro/nano-plastics on human reproductive health: A review
This review summarizes research on how micro- and nanoplastics affect human reproductive health in both men and women. Evidence from animal and lab studies shows that these particles can accumulate in reproductive organs, disrupt hormones, damage eggs and sperm, and cause inflammation and oxidative stress. While human studies are still limited, the growing body of evidence suggests that microplastic exposure is a potential threat to fertility that warrants further investigation.
The reproductive and transgenerational toxicity of microplastics and nanoplastics: A threat to mammalian fertility in both sexes
This review examines how microplastics and nanoplastics can accumulate in reproductive organs and harm fertility in both males and females. In animal studies, exposure led to damaged sperm, disrupted hormones, and abnormal ovary and uterus structure. Offspring of exposed mothers also showed metabolic problems, immune issues, and cognitive disorders, suggesting these particles may affect future generations.
