Abstract

Overview

Recent increases in human exposure to 150 kHz intermediate-frequency electromagnetic radiation (IF EMR) have prompted research into its effects on male fertility. This study investigates these potential impacts using adult male Sprague-Dawley rats.

Methods

• Subjects: Fourteen male rats divided into control and EMR-exposed groups.
• Exposure: Continuous irradiation at 150 kHz for 8 weeks.
• Metrics Evaluated: Body and testicular mass, rectal temperature, testicular histology, histometry, sperm analysis, and serum gonadotrophic hormone levels.

Findings

No significant change was found in body mass, rectal temperature, or overall testicular histology between the control and EMR groups. However, notable findings included:

• Decrease in testicular mass.
• Reduction in interstitial cell count.
• Lower sperm motility trajectories.
• Increase in sperm distal cytoplasmic droplets.
• Rise in follicle-stimulating hormone levels.

Conclusion

While overall most male fertility parameters were unaffected, specific detrimental effects were observed relevant to testicular mass and function following prolonged exposure to 150 kHz EMR in male rats. This suggests potential risks to male fertility associated with prolonged EMF exposure.
