Features, Potential Invasion Pathways, and Reproductive Health Risks of Microplastics Detected in Human Uterus
AI summary Read the abstract
Researchers found microplastics in the uterine lining of 22 women, identifying common plastics like polyamide, polyurethane, and PET in sizes ranging from 2 to 200 micrometers. In mouse experiments, microplastic exposure led to reduced fertility, abnormal offspring sex ratios, and significant uterine inflammation. These findings raise serious concerns about the potential impact of microplastic contamination on female reproductive health and pregnancy outcomes.
Microplastics (MPs) are ubiquitous in global ecosystems and may pose a potential risk to human health. However, critical information on MP exposure and risk to female reproductive health is still lacking. In this study, we characterized MPs in human endometrium and investigated their size-dependent entry mode as well as potential reproductive toxicity. Endometrial tissues of 22 female patients were examined, revealing that human endometrium was contaminated with MPs, mainly polyamide (PA), polyurethane (PU), polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), and polyethylene (PE), ranging from 2-200 μm in size. Experiments conducted in mice demonstrated that the invasion of the uterus by MPs was modulated either through diet-blood circulation (micrometer-sized particles) or via the vagina-uterine lacuna mode (larger particles reaching a size of 100 μm. Intravenous exposure to MPs resulted in reduced fertility and abnormal sex ratio in mouse offspring (P < 0.05). After 3.5 months of intragastric exposure, there was a significant inflammatory response in the endometrium (P < 0.05), confirmed by embryo transfer as a uterine factor leading to decreased fertility. Furthermore, human endometrial organoids cultured with MPs in vitro exhibited significantly apoptotic responses and disrupted growth patterns (P < 0.01). These findings raise significant concerns regarding MP contamination in the human uterus and its potential effects on reproductive health.

This review paper pulls together existing research on how microplastics, the tiny plastic particles found in our water, food, and air, may physically alter the vagina, uterus, and ovaries. The findings suggest these pollutants could disrupt reproductive organ structure and function, raising concerns about their potential impact on fertility and women's health. Since microplastics are now nearly impossible to avoid in daily life, understanding these risks matters for anyone concerned about long-term reproductive health.
Microplastics and reproductive health: implications for human health and areas for future research
AI summary Read the abstract
Tiny plastic bits called microplastics have been found in human testes, semen, ovarian fluid, and placentas, and this review of existing research suggests they may harm fertility by triggering inflammation, cell damage, and hormone disruption. While scientists are still figuring out exactly how much exposure is harmful and which types of plastic pose the biggest risk, the growing evidence is a reason to pay attention to reducing everyday plastic exposure. More research is needed before we know the full picture, but this is an area worth watching closely.
Microplastics exposure: implications for human fertility, pregnancy and child health
AI summary Read the abstract
This review examines growing evidence that microplastics accumulate in the human placenta and may affect pregnancy outcomes and child development. Given that exposure during pregnancy can program lifelong health in offspring, the presence of these tiny plastic particles in reproductive tissues raises important concerns about fertility, pregnancy complications, and children's health.
The Effect of Microplastics on the Female Reproductive System: Morphological Changes in the Vagina, Uterus, and Ovaries
AI summary Read the abstract
This review paper summarizes existing research on how microplastics, tiny plastic particles found throughout our environment, may physically alter the vagina, uterus, and ovaries, and explores possible reasons why this damage happens. As microplastics continue to show up in our food, water, and even human tissue, understanding their potential impact on female reproductive organs matters for assessing risks to fertility and long-term reproductive health.
Detection and quantification of various microplastics in human endometrium based on laser direct infrared spectroscopy

For the first time, researchers detected microplastics in human uterine lining tissue, finding 13 different types of plastic particles in the samples. Most particles were very small (under 100 micrometers), and certain habits like drinking from plastic bottles and chewing gum were linked to higher microplastic levels. This raises concerns about potential effects on reproductive health and fertility, though more research is needed.
