Abstract

Overview

The use of artificial insemination in cattle breeding has expanded globally, with insemination doses often transported via air, necessitating stringent radiation-based checks.

Methodology & Findings

• This study evaluates the effect of non-ionizing radiation (NIR) on bovine spermatozoa, using both freshly ejaculated and cryopreserved samples.
• Sperm was exposed to hand-held metal detectors for varied durations, and their motility and DNA integrity were analyzed.
• Fresh semen and post-cryopreservation irradiated doses showed a significant decrease in motility.
• Interestingly, NIR exposure showed potential short-term stimulation of spermatozoa velocity, although this effect varied after thawing.

Conclusion

Sperm DNA remained intact despite radiation exposure. The study highlights the possible risks of NIR commonly used for security at airports and events, emphasizing its adverse impact on reproductive capabilities in humans and animals, alongside noting an unusual short-term stimulation in sperm movement.
