Scientists Discovered Microplastics in Human Semen and Follicular Fluid
- Scientists detected microplastics in 69% of follicular fluid and 55% of seminal fluid samples at the 41st ESHRE meeting in 2025 in Paris.
- This research followed reports that microplastics, tiny plastic particles under 5mm, accumulate widely in human tissues and enter bodies via ingestion, inhalation, and skin contact.
- Researchers analyzed samples from 29 women and 22 men undergoing fertility procedures, identifying nine microplastic types, most frequently PTFE found in 31% of samples.
- Lead researcher Dr. Emilio Gomez-Sanchez noted animal studies link microplastics to inflammation and DNA damage but said current human evidence is insufficient to confirm fertility impairment.
- The findings raise concerns about reproductive health and support calls to reduce plastic use, but experts urge caution until further research clarifies potential human impacts.

Groundbreaking study finds microplastics in human reproductive fluids
A growing body of research warns that these nearly ubiquitous tiny particles, under 5mm in size, pose a threat to environmental and public health
Microplastics discovered in human reproductive fluids
New research presented at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) reveals the presence of microplastics in human reproductive fluids, raising important questions about their potential risks to fertility and reproductive health.
Study finds widespread microplastics in reproductive fluids, what it means for fertility
Microplastics have been detected in human reproductive fluids, with researchers finding them in 69% of female and 55% of male samples, raising concerns about potential effects on fertility. Although causality remains unproven, the findings prompt calls for reducing plastic exposure.
More and more research points to the omnipresence of microplastics, those small particles that worry about their possible impact on health and the environment.
Can plastic affect reproduction? That's the question researchers are asking after finding microplastics in both ovaries and semen.
