Reacción a "Microplastics found in reproductive fluids"

This study reveals the existence of microplastics in reproductive fluids. These substances were found in 69% of follicular fluid samples from 25 women and 30% of semen samples from 18 men.

The press release, however, refers to 29 females and 22 males, with slightly higher percentages of the presence of microplastics*.

Although previous published studies have demonstrated the presence of microplastics in reproductive fluids, this work studies selected polymers, of which polytetrafluoroethylene (PTFE) is the most frequently found in 69% of follicular fluid samples and 41% of semen samples. These results are supported by sound methodology and demonstrate how the increased use of plastics in everyday life can affect the reproductive system in humans.

The main limitation of the study is the low number of cases. However, as direct evidence of the effects of microplastics on human health is still scarce, this study opens a research avenue in this area to assess the risk of the presence of microplastics on human reproduction. Of particular concern is the ability of these particles to act as vectors for other pollutants, such as persistent organic pollutants and heavy metals, which can adsorb on their surfaces and be transported into the body.

In conclusion, this work underlines the need for future studies to fully understand the risks posed by microplastics on reproductive health and to inform on the danger of their routine use.
