Scientists have discovered microplastics in human penile tissue for the first time, raising concerns about their proliferation and potential health impacts.
The study, published in IJIR: Your Sexual Medicine Journal, found seven types of microplastics in four out of five samples from men with erectile dysfunction (ED) undergoing penile implant surgery.
These microplastics, ranging from less than 5 millimeters to as small as 1 micrometer, are fragments of larger plastics that degrade chemically or physically.
Lead author Ranjith Ramasamy, a reproductive urology expert, based his research on previous studies finding microplastics in the human heart. Given the penis’s vascular nature, Ramasamy wasn’t surprised by the findings. The samples, analyzed using chemical imaging, revealed polyethylene terephthalate (PET) and polypropylene (PP) as the most prevalent microplastics.
The study underscores the need for further research to determine if microplastics contribute to conditions like ED and to understand their broader health implications.
Toxicologist Matthew J. Campen highlighted the ubiquity of plastics in the body and their potential to disrupt normal bodily functions, including erection and sperm production.
Prior research by Campen found high levels of microplastics in human testicles compared to animal testes.
Experts recommend reducing plastic exposure by using stainless steel and glass containers, avoiding microwaving food or beverages in plastic, and not putting plastic in dishwashers to prevent chemical leaching.
