Rats exposed to 2.4 GHz Wi-Fi radiation for one year showed increased sperm head defects and decreases in epididymis weight, seminal vesicle weight, seminiferous tubule diameter, and tunica albuginea thickness.

Plain English Summary

Summary written for general audiences

The study used Wistar Albino adult male rats divided into a sham group and an exposure group, with rats in the exposure group exposed to 2.4 GHz radiofrequency radiation for 24 hours a day during 12 months. Sperm head defects increased in the exposed group, and weight of the epididymis and seminal vesicles, seminiferous tubule diameter, and tunica albuginea thickness all decreased. Other measured parameters did not show statistically significant differences between the groups.

Why This Matters

The study measured sperm motility, concentration, tail defects, head defects, and total morphologic defects, as well as weights of the testes, left epididymis, prostate, and seminal vesicles. Seminiferous tubule diameter and tunica albuginea thickness were also measured, and results were evaluated using Johnsen's score. The exposure level used was 2420 μW/kg averaged over 1 gram of tissue. The researchers concluded that long-term exposure to 2.4 GHz RF from Wi-Fi affects some reproductive parameters of male rats.

Study Details

The aim of this study was to investigate long-term effects of radiofrequency radiation (RFR) emitted from a Wireless Fidelity (Wi-Fi) system on testes.

The study was carried out on 16 Wistar Albino adult male rats by dividing them into two groups such ...

In conclusion, we observed that long-term exposure of 2.4 GHz RF emitted from Wi-Fi (2420 μW/kg, 1 g average) affects some of the reproductive parameters of male rats. We suggest Wi-Fi users to avoid long-term exposure of RF emissions from Wi-Fi equipment.
