Plain English Summary
Researchers exposed male mice to 2.45-GHz microwave radiation (the same frequency used by Wi-Fi and microwaves) for 2 hours daily over 30 days at very low power levels. The exposed mice showed significant decreases in sperm count and viability, reduced testosterone levels, and damaged reproductive tissue. The study suggests these effects occur through oxidative stress, where radiation generates harmful free radicals that damage cells.
Why This Matters
This study adds to mounting evidence that chronic microwave exposure can harm male fertility, even at power levels far below current safety standards. The 0.018 W/kg SAR used here is roughly 80 times lower than the FCC limit of 1.6 W/kg, yet still produced measurable reproductive damage after just 30 days of exposure. What makes this research particularly relevant is the 2.45-GHz frequency, which is identical to Wi-Fi routers and microwave ovens that surround us daily. The researchers identified oxidative stress as the likely mechanism, meaning the radiation generates free radicals that damage sperm cells and hormone-producing tissue. This finding aligns with dozens of other studies showing similar reproductive effects from RF radiation. The reality is that men today carry phones in their pockets and work surrounded by wireless devices emitting these same frequencies for hours each day.

Where This Falls on the Concern Scale
Study Details
Electromagnetic radiations are reported to produce long-term and short-term biological effects, which are of great concern to human health due to increasing use of devices emitting EMR especially microwave (MW) radiation in our daily life. In view of the unavoidable use of MW emitting devices (microwaves oven, mobile phones, Wi-Fi, etc.) and their harmful effects on biological system, it was thought worthwhile to investigate the long-term effects of low-level MW irradiation on the reproductive function of male Swiss strain mice and its mechanism of action.

Further, these adverse reproductive effects suggest that chronic exposure to nonionizing MW radiation may lead to infertility via free radical species-mediated pathway.
