I heard that microplastics were found in the penis. Could this be a cause of erectile dysfunction?

Yes, in one study, microplastics were found in the penises of men with severe erectile dysfunction. Scientists suggest that microplastics may disrupt hormonal balance (lowering testosterone) and impair vascular function, which can affect erections. However, these are still preliminary findings, and most research has been conducted on animals. If you are concerned about erectile dysfunction, it is important to see a doctor rather than self-diagnose.
