Plastic is everywhere.
Microplastics could be contributing to a global fall in fertility Significant concentrations of microplastics have been found in human testicles, raising concerns they may be adding to the global decline in sperm quality. Researchers from the University of New Mexico analysed testicular tissue from both humans and dogs, and found every sample included microplastics. In total, they found 12 different types of material.
Plastic production has increased enormously since the 1950s, and plastics take hundreds of years to decompose. This was then heated to 600C, as different plastics emit different gases at certain temperatures, allowing the researchers to determine which plastics were present. In dogs, the average concentration of microplastics was 122.63 micrograms per gram of tissue – a microgram is a millionth of a gram. In humans, the concentration was almost three times higher at 329.44 micrograms per gram.
