This animal experiment assessed GSM-modulated 3.5 GHz RF exposure in male Wistar rats and reported hormonal, oxidative, and histological changes consistent with testicular impairment. RF exposure was associated with lower testosterone, LH, and FSH, higher oxidative stress (increased MDA and TOS), and degenerative testicular histology. Coenzyme Q10 supplementation partially mitigated several reported changes. The authors caution against generalizing these results to FR1 5G NR signals and call for further research.
