Environmental toxins, including heavy metals and microplastics, appear in semen earlier and in higher concentrations than in blood, serving as an early indicator of exposure.

“The presence of environmental toxins in semen has long been recognized as an early indicator of exposure. For instance, studies have shown that new exposure to heavy metals like cadmium, copper, and zinc leads to earlier and higher concentrations of these metals in semen, with a corresponding decline in semen quality and viability. My findings suggest that this principle extends to microplastic particles as well: microplastics appear in semen earlier and in potentially higher concentrations.”
