New research presented at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) has shed light on the presence of microplastics in human reproductive fluids. This discovery raises important questions about the potential risks these microplastics may pose to fertility and reproductive health.
The study involved the examination of follicular fluid from 29 women and seminal fluid from 22 men, both of which are crucial components in natural conception and assisted reproduction. Researchers identified a variety of commonly used microplastic polymers in both groups, including polytetrafluoroethylene (PTFE), polystyrene (PS), polyethylene terephthalate (PET), polyamide (PA), polypropylene (PP), and polyurethane (PU).
Microplastics were found in 69% of the follicular fluid samples analyzed, with PTFE being the most frequently detected polymer. In seminal fluid samples, microplastics were present in 55% of the samples, once again with PTFE as the most prevalent polymer.
Lead researcher Dr. Emilio Gomez-Sanchez expressed surprise at the prevalence of microplastics in the reproductive fluids studied. While previous studies have shown that microplastics can be found in various human organs, the high occurrence in reproductive fluids underscores the need to investigate potential implications for human reproductive health.
Although this study did not directly assess how microplastics affect fertility, animal studies have shown that these particles can induce inflammation, DNA damage, and endocrine disruptions in tissues where they accumulate. The research team plans to expand their analysis to a larger cohort and explore the relationship between microplastics and egg or sperm quality.
Dr. Gomez-Sanchez emphasized that while the presence of microplastics in reproductive fluids is concerning, fertility is influenced by various factors. The findings should not cause alarm among individuals trying to conceive, but it is advisable to take steps to reduce exposure to microplastics.
Professor Dr. Carlos Calhaz-Jorge added that the findings should be considered as a reason to limit the use of plastics in daily life. The study abstract is set to be published in Human Reproduction.
In conclusion, the discovery of microplastics in human reproductive fluids highlights the need for further research into their potential impacts on fertility and reproductive health. By taking steps to reduce exposure to microplastics, individuals can help safeguard their reproductive well-being.
