View Original AbstractMilitary-strength electromagnetic pulses caused lasting sperm damage in mice, but antioxidant supplementation provided significant protection against reproductive harm.
Plain English Summary
Researchers exposed young male mice to electromagnetic pulses (EMPs) for four weeks and found significant damage to sperm production and testicular health. The mice that received a protective antioxidant supplement (selenium-rich Cordyceps fungi) showed much less reproductive damage. This suggests that electromagnetic radiation can harm male fertility, but certain protective compounds might help reduce this damage.
Why This Matters
This study adds to growing evidence that electromagnetic exposures can damage male reproductive health. The 200 kV/m electric field intensity used here is extremely high - far beyond typical consumer device exposures - representing military-grade electromagnetic pulse conditions. However, the biological mechanisms demonstrated (oxidative stress, cellular damage to sperm-producing cells) are the same pathways affected by lower-level EMF exposures from everyday sources like cell phones and WiFi. What makes this research particularly valuable is its demonstration that the reproductive damage persisted for at least 60 days after exposure ended, suggesting lasting effects on fertility. The protective effect of antioxidant supplementation also supports the oxidative stress theory of EMF harm that appears consistently across EMF research.

Study Details
We sought to determine whether EMP exposure (1) induces biological damage on reproductive health and (2) the extent to which selenium-rich Cordyceps fungi (daily coadministration) offer protection on the testicles and spermatozoa.
In a preclinical randomized study, 3-week-old male BALB/c mice were repeatedly exposed to EMP (peak ...
The group without Cordyceps cotreatment displayed decreased spermatozoa formation, shrunk seminifero...
