This review examines the growing evidence linking microplastic and nanoplastic exposure to potential effects on human fertility. Researchers noted that these tiny plastic particles have been detected in blood, placenta, and seminal fluid, suggesting continuous systemic exposure and the ability to cross key biological barriers. Animal studies indicate that microplastics may affect reproductive health through oxidative stress, hormonal disruption, and tissue damage, though more standardized human research is needed.

The authors found microplastics detected in testes, ovaries, placenta, and semen, and summarized mechanistic evidence linking them to hormonal disruption, oxidative stress, and impaired gamete function.
Exposure to micro- and nanoplastics and human reproductive outcomes: a systematic review
This systematic review summarizes existing research on whether micro and nanoplastics affect human fertility and pregnancy outcomes. While the evidence is still emerging, the review found that these particles have been detected in placenta and fetal tissue, raising important questions about potential effects on reproductive health that warrant further study.
Health Implications of Widespread Micro- and Nanoplastic Exposure: Environmental Prevalence, Mechanisms, and Biological Impact on Humans
This review summarizes how microplastics and nanoplastics enter the human body through food, air, and skin contact, then travel through the bloodstream to accumulate in various organs. Health effects range from immediate problems like pain and inflammation to long-term conditions including infertility, chronic lung disease, and potentially cancer, though the exact concentrations that build up in the body and the full extent of harm are still being studied.

This review summarized current evidence on microplastic detection in human blood and placenta, discussing what is known about how these particles enter the bloodstream and reach fetal tissue. The authors highlight the potential implications for maternal and fetal health.
The Plastic Within: Microplastics Invading Human Organs and Bodily Fluids Systems
This review documents the presence of microplastics in human organs and body fluids including the liver, blood, heart, placenta, breast milk, lungs, and reproductive tissues. The particles enter through ingestion, inhalation, and skin contact, and may also be introduced through invasive medical procedures. The widespread distribution of microplastics throughout the body raises concerns about their potential effects on organ function and long-term health.
A systematic review of the impacts of exposure to micro- and nano-plastics on human tissue accumulation and health
This systematic review found growing evidence that micro- and nanoplastics accumulate in human tissues including lungs, gut, and blood, with lab studies showing potential disruption to immune, reproductive, endocrine, and nervous systems. The review identifies ingestion, inhalation, and dermal contact as the three main exposure routes and highlights that the smallest nanoplastic particles pose the greatest concern due to their ability to cross biological barriers.
A review on micro- and nanoplastics in humans: Implication for their translocation of barriers and potential health effects
This review compiles evidence showing that micro- and nanoplastics have been found in human blood, lungs, placenta, and other organs, and can cross protective barriers including the blood-brain and placental barriers. The accumulated evidence links these particles to inflammation, oxidative stress, hormone disruption, and potential effects on reproduction and brain health, though more research is needed to determine exact risk levels.
