Scientists Found Microplastics In Human Ovaries

A recent report shows evidence of what scientists have feared for a long time: presence of microplastics in human ovaries.

For the first time, scientists have discovered microplastics in the follicular fluid of human ovaries, according to a new peer-reviewed study out of Italy. This fluid plays a crucial role in nourishing and developing a woman's eggs, and researchers have alarmingly found plastic particles in 14 out of 18 samples collected from patients undergoing fertility treatment.

The study, led by researcher Luigi Montano and published in Ecotoxicology and Environmental Safety, marks a major step forward in understanding how deep plastic pollution runs — not just in the environment but in our bodies.

Follicular fluid surrounds the egg cells in the ovaries and helps regulate hormones, nutrient delivery, and fertilization. The presence of microplastics in this fluid raises the possibility that these tiny particles are interfering with essential reproductive processes.

"This discovery should serve as an important warning signal about the invasiveness of these emerging contaminants in the female reproductive system," the study states, according to the Guardian.

Montano's broader research has already revealed microplastics in human semen and urine, and animal studies suggest the plastics may disrupt ovarian function and reduce the ability to conceive.

Microplastics — which form when larger plastics break down — are everywhere: in our food, water, air, and even in newborns. These tiny particles often carry toxic chemicals like PFAS and bisphenol, which are known hormone disruptors and have been linked to cancer, neurological disorders, and developmental delays.

Now, scientists suspect these particles could further be contributing to declining sperm counts and fertility struggles in both men and women. The research notes a "possible presence of correlation between the concentration of microplastics" and reproductive health in the women who participated in the new study.

"This stuff is increasing in our world exponentially," said toxicologist Dr. Matthew Campen in an earlier New York Times report on microplastic exposure. "And it's already inside us."
