I remember this story from about 6 months ago:
Freeze your sperm now; microplastics could be making us infertile | ScienceWriters (www.NASW.org)
According to a 2021 Nature article, some researchers believe that the amount of microplastics in the environment is not enough to impact human health. However, some researchers are convinced that reduced sperm count and sperm quality in humans is related to the increased microplastic pollution in water and food, and human autopsy studies have found microplastics in human placentas and posthumous liver and fat tissue samples.
While studies in humans have been inconclusive, due to ethical reasons, lab mice have provided some evidence of the link between microplastics and male infertility. In a study where mice’s water supplies were exposed with different amounts of polystyrene microplastics for 35 days, researchers found that mice who were exposed to microplastics had lower sperm counts than a control group who were not exposed.
The sperm of the mice who received the highest dose of microplastics also had significantly more abnormalities than the sperm of the mice who were not exposed. For example, some of the sperm had two tails, or visible swelling on its head.
