Microplastics were found in 69% of women’s follicular fluid and 55% of men’s seminal fluid, raising concerns about possible fertility implications.
In a recent study presented at an international reproductive health conference, researchers detected microplastics in the follicular fluid of 69% of women and in the seminal fluid of 55% of men. Using advanced microscopy techniques, the team identified polymers including PTFE (commonly known as Teflon), polystyrene, PET, polyamide, polypropylene, and polyurethane.
Lead researcher Dr. Emilio Gomez-Sanchez stated, “Previous studies had already shown that microplastics can be found in various human organs. We were struck by how common they were,” noting that PTFE appeared in 31% of female samples and 41% of male samples.
Although the direct impact on fertility is not yet confirmed, animal studies suggest that microplastics may trigger inflammation, oxidative stress, DNA damage, and hormonal disruption, potentially affecting egg and sperm quality. “It’s possible they could impair egg or sperm quality in humans, but we don’t yet have enough evidence to confirm that,” said Dr. Gomez-Sanchez. He advised limiting exposure by using glass containers for food storage.
