Sex toys may seem harmless, but many have not been assessed for health risks and could have terrible effects.

According to experts, our body may absorb the chemicals in the toys and recent experiments at Duke University found that four different sex toys, including anal toys, beads, dual vibrators, and external vibrators, shed nanoplastic fragments when mechanically rubbed and scraped.

What’s more, all these sex toys were found to contain phthalates; a group of chemicals that that can damage the liver, kidneys, lungs, and the reproductive system, at high enough concentrations.
