In young male mice, electromagnetic pulse exposure reduced sperm formation and testicular antioxidative capacity, and daily selenium-rich Cordyceps fungi co-treatment alleviated those effects.

Plain English Summary

Summary written for general audiences

Researchers conducted a preclinical randomized study using 3-week-old male BALB/c mice repeatedly exposed to electromagnetic pulses at a peak intensity of 200 kV/m, 5 days per week for four consecutive weeks. Some mice also received daily co-administration of selenium-rich Cordyceps fungi at 100 mg/kg. Mice exposed without Cordyceps showed decreased sperm formation, shrunk seminiferous tubule diameters, and diminished antioxidative capacity at 28 and 60 days after exposure. Daily Cordyceps co-treatment alleviated the testicular damage, increased sperm formation, and reduced apoptotic spermatogenic cells.

Why This Matters

The study sought to answer two questions: whether electromagnetic pulse exposure induces biological damage on reproductive health, and whether selenium-rich Cordyceps fungi offer protection on the testicles and spermatozoa. Testicular index and spermatozoa formation were measured at baseline and at 1, 7, 14, 28, and 60 day time points after exposure. The researchers noted that these observations warrant further preclinical and clinical studies as an innovative approach for potential protection against electromagnetic radiation.

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 ...

Quick Questions About This Study

The study used 3-week-old male BALB/c mice.
Mice were exposed to electromagnetic pulses at a peak intensity of 200 kV/m, pulse edge 3.5 ns, pulse width 15 ns, 0.1 Hz, and 400 pulses per day.
Mice without Cordyceps co-treatment showed decreased sperm formation, shrunk seminiferous tubule diameters, and diminished antioxidative capacity at 28 and 60 days after exposure.
Daily Cordyceps co-treatment alleviated testicular damage, increased sperm formation, and reduced apoptotic spermatogenic cells in exposed mice.
The researchers stated that these observations warrant further preclinical and clinical studies as an innovative approach for potential protection against electromagnetic radiation.
