50 GHz microwave exposure damaged sperm cells and disrupted reproduction in rats, suggesting 5G frequencies may contribute to male fertility decline.

Plain English Summary

Summary written for general audiences

Researchers exposed male rats to 50 GHz microwave radiation (similar to 5G frequencies) for 2 hours daily over 45 days and examined the effects on sperm cells. The exposed rats showed significant damage to sperm quality, including increased cell death, disrupted cell division cycles, and reduced antioxidant defenses that normally protect cells from damage. These changes suggest the radiation could contribute to male fertility problems.

Why This Matters

This study adds to growing evidence that microwave radiation can harm male reproductive health, even at relatively low power levels. The 50 GHz frequency tested falls within the millimeter wave spectrum used by 5G networks, making these findings particularly relevant as this technology expands globally. What's striking is that the researchers observed multiple types of cellular damage in sperm cells - from increased programmed cell death to disrupted DNA replication cycles. The science demonstrates that reproductive cells appear especially vulnerable to EMF exposure, likely because they're rapidly dividing and have high metabolic activity. While this was an animal study, the biological mechanisms observed mirror those found in human studies examining cell phone radiation and sperm quality. The reality is that male fertility rates have been declining for decades in developed countries, and EMF exposure represents one potential contributing factor that deserves serious consideration.
