Scientific American: Microplastics Have Now Been Found in Testicles. How Bad Is That?


A study by Hu et. al (2024) sampled 42 dog and 23 human testicles for presence of microplastics, and the researchers reported microplastics in every single one. Because microplastics are known to harm hormonal levels in the body, this wasn’t a surprise to many researchers. Additionally, the scientists saw that humans had three times more microplastics in their testes than the canines, which can be easily attributed to humans eating, drinking, and surrounding themselves with plastic materials UCSF Tracey Woodruff states.
