Comparison of the effect of changing the spatial distance with exposure time to mobile phones radiation on the structure and function of the testis in NMRI mice

Abstract

Overview

The study investigates the impact of varying spatial distances and exposure durations of radio frequency (RF) radiation from mobile phones on the testicular structure and function in NMRI mice.

Methodology

Mice were grouped into control, exposed, and sham categories. Exposed mice were further divided based on proximity (5 cm and 20 cm) to the radiation source and exposure durations (6 and 10 weeks). Exposure occurred 5 days per week, 6 hours per day. Sham groups mimicked exposure setups but without actual radiation.

Findings

• The structural changes in testicles were more dependent on the distance from radiation source than on exposure time.
• Decreases in testicle diameter and sperm motility were notably time-dependent.
• Sperm motility exhibited changes based on proximity to the radiation source, hinting at a complex interaction between distance and exposure duration.

Conclusion

This study highlights significant yet unpredictable effects of radiation on testicular function and structure, influenced by both the proximity to the radiation source and the duration of exposure. Stress factors played a critical role, sometimes overshadowing the effects of RF radiation.
