Exposure to non-ionizing electromagnetic radiation of public risk prevention instruments threatens the quality of spermatozoids

Abstract

Overview

The following abstract details research concerning the impact of non-ionizing radiation (NIR) from public risk prevention instruments on bovine spermatozoa. This study is highly relevant due to the frequent use of these instruments at places such as airports and during public events. The findings contribute to our understanding of how routine exposure to NIR could affect reproductive capabilities in both human and animal populations.

Methodology

The study utilized both freshly ejaculated and cryopreserved bovine spermatozoa exposed to different durations of NIR through a hand-held metal detector. The exposure times ranged from zero to sixty minutes for freshly ejaculated samples, and from zero to five minutes for cryopreserved samples pre and post freezing.

Findings

• Seminal analysis showed a decrease in both total and progressive motility in fresh and post-thaw semen that was exposed to radiation after cryoconservation.
• Interestingly, certain exposure intervals indicated a potential short-term stimulation in sperm velocity.
• Despite these mobility changes, DNA fragmentation assays confirmed that sperm DNA integrity remained intact.

Conclusion

This comprehensive study emphasizes the potential reproductive hazards posed by NIR exposure, a common element in modern security protocols. The ability of NIR to both reduce motility and paradoxically stimulate spermatozoa immediately post-exposure underscores the complex bioeffects of NIR on reproductive health. Such findings are crucial in understanding and mitigating the risks associated with routine NIR exposure.
