Polluted testicles may be the cause of rising male infertility

USA TODAY

Scientists have detected “significant concentrations” of microplastics in tissue form human testicles, raising concerns about their effects on reproductive health.
Microplastics refer to any plastics that are less than 5 millimeters (0.2 inches) in length.
The plastic particles have been found in our food, water, air and even in human placenta.
“The plastic makes a difference—what type of plastic might be correlated with potential function,” Yu said.
“PVC can release a lot of chemicals that interfere with [sperm production] and it contains chemicals that cause endocrine disruption.”
“These findings highlight the pervasive presence of microplastics in the male reproductive system in both canine and human testes, with potential consequences on male fertility,” they write.
However, more research is needed to confirm how these plastics might affect sperm production in humans.
We want to scientifically provide the data and make people aware there are a lot of microplastics.

The effects of microplastics on reproductive health are a cause for concern as scientists have found “significant concentrations” of them in human testicular tissue.

Polymers smaller than five millimeters (0.02 inches) in length are referred to as microplastics. Plastic particles have been discovered in human placentas, water, and food.

It has been demonstrated that the mixture of chemicals present in these microplastics can disrupt the body’s normal hormone release, raising the possibility of reproductive issues and certain types of cancer. For this reason, the discovery is concerning. Additionally, the surface of them may contain heavy metal toxins.

It’s not surprising that these microplastics have been discovered inside our bodies, as prior estimates place the average person’s weekly consumption at roughly the amount of a credit card.

Researchers from the University of New Mexico examined 46 canine tissue samples from private veterinary clinics and animal shelters in the City of Albuquerque, as well as anonymized postmortem tissue from 23 human testes provided by the New Mexico Office of the Medical Investigator, in a recent study that was published in the journal Toxicological Sciences.

The average concentration of microplastics per gram in humans was 329.44, whereas in dogs it was 122.63. Microplastics were found in all tested samples.

Research leader Xiaozhong “John” Yu, a professor at the University of New Mexico’s College of Nursing, said in a statement, “I was skeptical at first about whether microplastics could enter the reproductive system [at all].”. “I was taken aback when I initially got the results for dogs. When I saw the results for humans, I was even more shocked. “.

Additional analysis on the dog samples showed a correlation between lower sperm counts and higher levels of PVC, one type of plastic, in the testis tissue.

According to Yu, “the plastic matters—what kind of plastic might be connected with possible function.”. “PVC contains chemicals that cause endocrine disruption and can release a lot of chemicals that interfere with [sperm production]. ****.

More than half a century ago, the U.S. S. have dropped by 50%, which the researchers think could be impacted by these microplastics to some extent.

They state, “These results demonstrate the widespread presence of microplastics in the male reproductive system in both canine and human testes, with potential implications on male fertility.”.

To confirm how these plastics might impact human sperm production, more investigation is necessary. “There are many unknowns,” Yu remarked. “The possible long-term impact needs to be carefully considered. “.

“We want to avoid frightening people,” he continued. Our goal is to raise awareness about the abundance of microplastics by providing data based on science. We are able to alter our lifestyles, modify our behavior, and better avoid exposures by making our own decisions. “.”.
