New research presented at the 41st Annual Meeting of ESHRE has revealed the widespread presence of microplastics in human reproductive fluids. This includes follicular and seminal fluid samples.
Scientists examined reproductive samples from 29 women and 22 men. Their goal was to investigate whether microplastics had infiltrated these essential components of human fertility. Their analysis confirmed that microplastics are indeed present, raising urgent questions about their impact on reproductive health.
Microplastics Found in Over Two-Thirds of Follicular Fluid Samples
The research team identified several common microplastic polymers in the reproductive fluids they studied. These polymers include polytetrafluoroethylene (PTFE), polystyrene (PS), and polyethylene terephthalate (PET).
Microplastics were detected in 69% of the follicular fluid samples. This fact underscores the alarming prevalence of plastic particles in the human body. Notably, PTFE was the most frequent polymer, appearing in 31% of the tested samples.
Male Seminal Fluid Also Contained Microplastics in More Than Half the Samples
Similarly, the study discovered that 55% of the male seminal fluid samples contained microplastics, with PTFE again emerging as the most common polymer.
Although the study did not measure fertility outcomes directly, researchers emphasised the need for more data to understand whether these particles affect egg and sperm quality over time.
potential Health Risks and Next Steps for Research
Animal studies have shown that microplastics can trigger inflammation, free radicals, DNA damage, and endocrine disruption, all of which may harm reproductive cells.
While researchers cannot yet confirm similar effects in humans, they highlighted the importance of further studies. The next phase of research will include larger sample groups and detailed analysis of environmental exposures.
Practical Ways to Reduce Microplastic Exposure in Daily Life
Although fertility depends on many factors, experts recommend taking practical steps to limit microplastic exposure whenever possible.
You can reduce your intake by storing and heating food in glass containers, avoiding excessive use of bottled water, and choosing products with minimal plastic packaging.
A Call for Caution, Not Panic
Lead researcher Dr. Emilio Gomez-Sanchez reassured the public that there is no cause for immediate alarm. However, the findings should prompt reflection on our daily use of plastics.
As Professor Dr. Carlos Calhaz-Jorge noted, this evidence strengthens the case for reducing plastic consumption to protect both environmental and human health in the long term.
