It is possible to drastically reduce the concentration of microplastics in the blood and semen through targeted interventions.

Bryan Johnson relies on a personal observation correlated with a recent meta-analysis (published in Science of The Total Environment, 2024) which establishes a link between the presence of microplastics and impaired semen quality, including a decrease in sperm motility and concentration. While the association between microplastics and reproductive health is an active and concerning area of research, the exact method for "eliminating 85%" of these particles via lifestyle changes is not yet validated by randomized clinical trials (RCT). Current scientific literature confirms that we ingest and inhale these particles daily, making such a rapid and significant reduction difficult to generalize without knowing the specific bodily elimination mechanisms. It is highly probable that the creator has modified environmental variables (diet, containers, filtration), but the direct cause-and-effect link between these specific changes and his numerical results remains to be scientifically demonstrated. The observation is fascinating, but it constitutes an isolated case (n=1) that will need to be confirmed by larger clinical studies.
