A shocking new study published in Environmental Health Perspectives has found a strong correlation between microplastic exposure and the development of endometriosis, a painful condition where tissue similar to the uterine lining grows outside the uterus. The research, conducted across five countries, analyzed tissue samples from over 1,200 women with endometriosis and found microplastics in 89% of the lesions.
Microplastics—tiny plastic particles less than 5mm in size—have infiltrated nearly every aspect of modern life, from food and water to household dust. The study identified polyethylene (common in packaging) and polyvinyl chloride (used in pipes and flooring) as the most prevalent types in endometrial tissue. Researchers believe these particles may disrupt hormonal pathways and trigger chronic inflammation, exacerbating the growth of abnormal tissue.
Dr. Hannah Wei, the study’s lead author, warned, “This is the first direct evidence linking microplastics to endometriosis. Given how widespread these particles are, the implications for women’s reproductive health are deeply concerning.”
Endometriosis affects roughly 10% of women of reproductive age, causing severe pain, infertility, and other complications. Current treatments focus on symptom management, but this discovery opens new avenues for prevention and targeted therapies. Advocacy groups are now calling for stricter regulations on plastic production and better filtration systems to reduce exposure.
“This isn’t just an environmental issue—it’s a women’s health crisis,” said Lisa Monroe, director of the Endometriosis Foundation. “We need urgent action to limit plastic pollution and fund further research into how these particles are affecting our bodies.”
