Microplastics Detected in Human Semen and Female Reproductive Fluids, Raising Infertility Crisis Concerns
Microplastics Invade Human Reproductive Fluids, Raising Fertility Concerns
Microplastics—tiny particles found from the deepest oceans to the highest mountains—are now detected in human reproductive fluids, according to a study presented at the European Society of Human Reproduction and Embryology (ESHRE) conference. Researchers warn this could threaten fertility by damaging sperm and egg quality.
Scientists analyzed follicular fluid from 29 women and seminal fluid from 22 men. Over half contained microplastics, including particles from non-stick coatings, polystyrene, plastic containers, and textiles. Lead researcher Dr. Emilio Gomez-Sanchez noted microplastics were present in 69% of female samples and 55% of male samples, stating, “We were struck by how common they were.”
While the study didn’t prove direct harm, animal research links microplastics to inflammation, DNA damage, and hormone disruption. “They could impair reproductive cells, but we need more evidence,” Dr. Gomez-Sanchez cautioned.

How Do Microplastics Reach Our Bodies?
These particles enter through food, water, air, and skin contact, traveling via the bloodstream to organs. Everyday items like tea bags, plastic bottles, and baby bottles are major sources. A 2023 study found a single tea bag can release billions of microplastics.
Expert Reactions
Dr. Carlos Calhaz-Jorge of ESHRE urged reduced plastic use, calling the findings “an additional argument for caution.” However, Dr. Stephanie Wright of Imperial College London highlighted contamination risks during lab analysis: “We can’t rule out procedural artifacts.”

Prior Evidence of Widespread Contamination
Microplastics have been found in breast milk, blood, and brain tissue. A 2020 study detected them in 80% of blood samples tested. Their long-term health effects remain unclear, but potential risks include:
- Inflammation triggering tissue damage.
- Toxin accumulation from chemicals like mercury or pesticides bound to plastics.
- Immune responses mistaking particles for threats.
The Path Forward
Researchers stress the need for urgent studies linking microplastic exposure to fertility outcomes. Meanwhile, reducing plastic use—avoiding single-use containers, opting for natural fabrics, and filtering tap water—may minimize risks.
“Presence doesn’t equal harm, but we must act prudently,” said Prof. Fay Couceiro of the University of Portsmouth. As science races to uncover impacts, the ubiquity of microplastics underscores a pressing environmental and health crisis.
