We know that we can find microplastics even in the depths of the ocean, but these structures have apparently permeated every aspect of our lives. Resembling people and other beings They cannot protect themselves against microplastics. In the latest study, microplastic was found in testicles of humans and dogs.

at the University of New Mexico Professor Xiaozhong “John” Yu The long-term effect of the environment on the human reproductive system was examined in the study conducted by a team led by Dr. After microplastics appeared in every human placenta examined in a separate study, the scientist decided to investigate dogs as well. The reason for this situation is that dogs live in a similar environment.

12 different microplastics found

Scientists examining tissues from the testicles of humans and dogs found microplastics in all of these tissues. of 23 people and 47 dogs When examining the collected tissues, samples of 12 different types of microplastic were found. On the other hand, microplastic density was three times higher in tissue samples taken from humans.

Yu said in his statement that they initially did not expect microplastics to have penetrated reproductive systems, but the results surprised him. This job, microplastics in reproductive systems It also proved that it could penetrate. Scientists will now investigate whether these structures damage the testicles or sperm. It is thought that microplastics may play a role in the global decline in sperm quality.
