This experimental study exposed adult male Wistar rats to 900 MHz GSM-band cell phone-related waves for 2 or 3 weeks and assessed sperm parameters and total antioxidant capacity. All exposure groups showed significantly reduced sperm viability, motility, and total antioxidant capacity compared with controls.…

This animal study examined whether chronic low-level non-thermal 900 MHz electromagnetic radiation alters rat sleep EEG. Rats were exposed for 1 month (1 h/day) to either unmodulated 900 MHz or 900 MHz modulated at 8 and 16 Hz. The abstract reports that REM sleep measures were more affected than slow wave sleep,…

This animal study exposed male Fischer-344 rats to 900 MHz or 1800 MHz microwave radiation for 30 days (2 h/day) and compared outcomes to sham exposure. The authors report significant cognitive impairment along with increased oxidative stress in brain tissue in exposed rats. They also report increased inflammatory…

This rat study tested whether acute exposure to 0.9 and 1.8 GHz continuous-wave radiofrequency radiation alters blood-brain barrier permeability. Using Evans-blue/albumin as a tracer, the authors report no BBB leakage in exposed female rats but a significant increase in albumin in exposed male rat brains versus sham.…

This animal study assessed DNA damage in rat brain, liver, and kidney cells after repeated whole-body exposure to 915 MHz GSM-modulated RF radiation (SAR 0.6 W/kg) using the comet assay. Tail length was slightly increased in brain cells and differed more notably in liver and kidney samples versus sham controls, while…

This animal study examined whether an extremely low frequency magnetic field (7 mT, 40 Hz) used in magnetotherapy alters oxidative balance in rat brain after 10 days of exposure. The 30 min/day exposure condition was associated with increased lipid peroxidation, while the 60 min/day condition was associated with…

This animal PET study examined whether a weak 60-Hz magnetic field alters brain glucose utilization in rats. The abstract reports increased FDG uptake in hindbrain voxels when a 2.5-G field was oriented orthogonally to the sagittal plane, but not when field direction varied randomly. Distinct activation effects were…

This animal study examined whether prenatal exposure to mobile phone microwaves affects ovarian development in rats. Pregnant rats were exposed to a phone placed under the cage throughout pregnancy, with mostly standby exposure and brief periodic speech-mode exposure. Female pups assessed at 21 days had fewer ovarian…

This rat study examined sub-chronic exposure to a 30 MHz electromagnetic field at 0–1600 V/m for 8 hours/day, 5 days/week, over 56 days. The authors report no change in ovarian wet weight, but dose-related changes in estrous cycle timing, reproductive hormones (higher LH and lower E2 at higher exposures), and ovarian…

This rat study examined whether EMR from GSM mobile phones affects oxidant/antioxidant status. Compared with controls, exposed rats had lower plasma antioxidant vitamins (C, E, A), reduced glutathione, and lower CAT and SOD activities. The acute exposure condition was reported to produce larger decreases than the…

This rat study examined 900 MHz radiofrequency exposure (30 min/day for 30 days) and reported biochemical and histopathologic changes in endometrial tissue consistent with oxidative stress and tissue injury. The abstract reports increased NO and MDA and decreased antioxidant enzyme activities (SOD, CAT, GSH-Px) in…
