The Microplastics and Human Health: Focus on the Reproductive System
This review examined evidence that microplastics accumulate in human reproductive tissues and evaluated their potential effects on fertility and reproductive health. 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.
Microplastics detected in three types of female reproductive organs using micro-Raman spectroscopy
Researchers detected microplastics in tissue samples from three types of female reproductive organs — uterine tissue with adenomyosis, ovarian cysts, and fallopian tubes — collected from 60 women. Polyethylene and polypropylene were the most common types found, with most particles smaller than 20 micrometers. This study provides direct evidence that microplastics accumulate in human reproductive tissues, though more research is needed to determine whether they contribute to reproductive diseases.
O-280 Unveiling the hidden danger: detection and characterisation of microplastics in human follicular and seminal fluids
Researchers detected and characterized microplastics in human follicular fluid and seminal fluid, providing evidence that plastic particles are present in both male and female reproductive systems. Multiple types of microplastics were identified in the samples using advanced spectroscopic techniques. The findings add to growing evidence that microplastics reach human reproductive organs, raising important questions about their potential effects on fertility and reproductive health.
Microplastic presence in dog and human testis and its potential association with sperm count and weights of testis and epididymis
Researchers found microplastics in every dog and human testis sample tested, with human testes containing nearly three times more plastic than dog testes. Polyethylene was the dominant plastic type in both species, and certain plastics like PVC and PET were associated with lower testis weight. These findings suggest that widespread microplastic contamination of the male reproductive system could be contributing to declining sperm counts.
Atlas and source of the microplastics of male reproductive system in human and mice
Researchers mapped microplastic contamination throughout the male reproductive system in both humans and mice, finding plastics in the testes, epididymis, seminal vesicles, and prostate. The study suggests that microplastics found in semen likely originate from these reproductive organs rather than from external contamination. A lifestyle questionnaire revealed that living in urban areas, eating home-cooked meals, and using scrub cleansers were significant sources of microplastic exposure in men.
Detection of microplastics in the human penis
In the first study to look for microplastics in human penile tissue, researchers detected plastic particles in 80% of samples from six men undergoing surgery, with polyethylene terephthalate (PET) and polypropylene being the most common types. This finding adds the penis to the growing list of human organs where microplastics have been found, raising questions about potential effects on male reproductive health.
Method for label-free & non-destructive detection of microplastics in human formalin-fixed paraffin-embedded tissue sections
Researchers developed a new method to detect microplastic particles directly in preserved human colon tissue samples using advanced infrared microscopy, without destroying the tissue. They identified polyethylene, polystyrene, and PET particles within the tissue and observed signs of inflammation near the plastic particles, marking what may be the first workflow that combines microplastic detection with standard pathology analysis in human samples.
Detection of microplastics in human lung tissue using μFTIR spectroscopy
Researchers analyzed lung tissue from 13 people and found microplastics in 11 of the samples, identifying 12 different plastic types including polypropylene and polyester. The particles were found in all regions of the lungs, with significantly higher concentrations in the lower lung. This is one of the first studies to directly confirm that microplastics from everyday environments can be inhaled and accumulate deep in human lung tissue.
Prevalence and implications of microplastic contaminants in general human seminal fluid: A Raman spectroscopic study
Microplastics were detected in all 40 semen samples from men in the general population with no occupational plastic exposure, with an average of 2 particles per sample and polystyrene being the most common type. Sperm exposed to different plastic types showed varying motility, suggesting that the kind of microplastic present may matter for male fertility.
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.
Application of Infrared and Near-Infrared Microspectroscopy to Microplastic Human Exposure Measurements
This review evaluates how infrared and near-infrared microscopy techniques are being used to measure human exposure to microplastics from drinking water, dust, food, and air. Researchers found that while these spectroscopic tools are powerful for identifying plastic types and sizes, significant challenges remain in standardizing methods across different sample types. The study highlights that consistent, reliable exposure measurements are essential for understanding whether microplastic levels in everyday environments pose meaningful health risks.
Microplastics and male reproductive system: A comprehensive review based on cellular and molecular effects
This comprehensive review examines how microplastics affect the male reproductive system at cellular and molecular levels, drawing on studies from multiple scientific databases. Researchers found that microplastics can damage testicular structure and function, impair spermatogenesis, and disrupt sperm parameters through mechanisms including oxidative stress, inflammation, and activation of cell death pathways. The review highlights that microplastics reduce ATP production and trigger signaling cascades that may contribute to male fertility problems.
Optical photothermal infrared spectroscopic assessment of microplastics in tissue models and non-digested human tissue sections
Researchers developed a method using optical photothermal infrared spectroscopy to detect and map microplastics directly within tissue sections without requiring chemical or enzymatic digestion. The study suggests this approach preserves spatial information about where microplastics are located within tissue architecture, overcoming a key limitation of conventional digestion-based methods that can lose some particles.
The Invisible Intruder: a Review of Microplastics Accumulation in Human Tissues and Implications for Public Health, with Emphasis on Reproductive Health
This review synthesizes biomonitoring studies on microplastic and nanoplastic accumulation in human tissues, with particular emphasis on reproductive health effects. Researchers found these particles have been detected in blood, lungs, placentas, breast milk, testes, and brain tissue, raising questions about potential long-term implications for human health and reproduction.
Microplastics in human urine: Characterisation using μFTIR and sampling challenges using healthy donors and endometriosis participants
Researchers analyzed urine samples from healthy individuals and endometriosis patients, detecting microplastics in the majority of both groups, with 22 different polymer types found. While microplastic levels were not significantly different between the two groups, the finding that plastics like polyethylene, polystyrene, and PTFE are being excreted in human urine confirms that these particles are circulating through the body.
