This review summarizes research on how microplastics and nanoplastics affect female fertility across multiple species, from reproductive failure to developmental problems in offspring. The tiny particles can infiltrate the body through food, air, and skin, accumulating in reproductive tissues where they disrupt hormones and damage eggs. While animal studies cannot be directly applied to humans, the consistent findings across species raise serious concerns about the potential impact of microplastic exposure on women's reproductive health.

Microplastics (MPs) and nanoplastics (NPs) are emergent pollutants, which have sparked widespread concern. They can infiltrate the body via ingestion, inhalation, and cutaneous contact. As such, there is a general worry that MPs/NPs may have an impact on human health in addition to the environmental issues they engender. The threat of MPs/NPs to the liver, gastrointestinal system, and inflammatory levels have been thoroughly documented in the previous research. With the detection of MPs/NPs in fetal compartment and the prevalence of infertility, an increasing number of studies have put an emphasis on their reproductive toxicity in female. Moreover, MPs/NPs have the potential to interact with other contaminants, thus enhancing or diminishing the combined toxicity. This review summarizes the deleterious effects of MPs/NPs and co-exposure with other pollutants on female throughout the reproduction period of various species, spanning from reproductive failure to cross-generational developmental disorders in progenies. Although these impacts may not be directly extrapolated to humans, they do provide a framework for evaluating the potential mechanisms underlying the reproductive toxicity of MPs/NPs.

The reproductive and transgenerational toxicity of microplastics and nanoplastics: A threat to mammalian fertility in both sexes

AI summary Read the abstract

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.

Unraveling the threat: Microplastics and nano-plastics' impact on reproductive viability across ecosystems

AI summary Read the abstract

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.

Reproductive toxicity of micro- and nanoplastics

AI summary Read the abstract

This review summarizes existing research on how micro- and nanoplastics harm reproduction across many species, from marine invertebrates to mammals. The particles can cause oxidative stress and hormone disruption, leading to reduced fertility, abnormal embryo development, and toxic effects that pass to offspring. The findings raise concerns that human reproductive health could be similarly affected given our increasing exposure to these particles.

Adverse effects of microplastics and nanoplastics on the reproductive system: A comprehensive review of fertility and potential harmful interactions

AI summary Read the abstract

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.

A review of the impact of micro‐ and nanoplastics on female reproduction: What we know and gaps in knowledge

AI summary Read the abstract

This review examines what is known about how micro- and nanoplastics affect female reproductive health. Animal studies show these particles accumulate in ovarian tissue, disrupt hormones, and cause oxidative stress, leading to hormonal imbalances and ovarian damage, though research in humans is still limited.
