Researchers exposed female mice to 1800 MHz mobile phone radiation (the frequency used by GSM networks) and found it significantly damaged their reproductive systems. The radiation increased harmful stress molecules in the brain, ovaries, and uterus while reducing fertility hormones and the number of healthy egg follicles. This suggests that mobile phone radiation may impair female fertility through cellular stress pathways.

Researchers exposed brain support cells called astrocytes to repetitive magnetic stimulation at different frequencies to see how they responded. They found that 1 Hz magnetic pulses caused a significant increase in calcium levels inside these cells, which is a sign of cellular activation. This suggests that magnetic fields can directly influence brain cells beyond just neurons, potentially explaining some of the biological effects seen with magnetic field exposure.

Researchers exposed mice to 900 MHz cell phone radiation for 6 hours daily over several weeks, then infected them with a common fungal pathogen (Candida) to test their immune response. The radiation-exposed mice showed delayed wound healing, higher infection levels in their skin, and increased susceptibility to life-threatening systemic infections. This suggests that chronic exposure to cell phone frequencies may weaken the immune system's ability to fight off infections.
Mortazavi SMJ et al. · 2017
Iranian researchers exposed rats to 915 MHz radiofrequency radiation (similar to microwave ovens) for 4 hours daily over one week, then tested whether this 'primed' their liver cells to better handle a subsequent dose of gamma radiation. They found that low-power RF exposure increased antioxidant enzymes like glutathione, which helped protect liver tissue from oxidative damage when the rats were later exposed to harmful gamma radiation.

Italian researchers exposed brain cancer cells (neuroblastoma) to 50 Hz magnetic fields and aluminum compounds, both separately and together, to see if they would cause DNA damage. After exposing the cells to magnetic field levels ranging from 0.01 to 1 mT for up to 5 hours, they found no DNA damage, no changes in cellular stress markers, or any harmful synergistic effects when the exposures were combined. This suggests that short-term exposure to these power-frequency magnetic fields, even in combination with aluminum, does not appear to damage DNA in these particular brain cell types.
Danese E et al. · 2017
Italian researchers exposed blood samples from 14 healthy volunteers to 900 MHz radiofrequency radiation from a commercial mobile phone for 30 minutes, then examined the cells for DNA damage markers called gamma-H2AX foci. They found no significant increase in DNA breaks or genetic damage compared to unexposed blood samples. This suggests that short-term mobile phone radiation exposure at typical frequencies may not cause immediate detectable DNA damage in human immune cells.

Researchers exposed brain cells to cell phone radiation (1950 MHz) for 2 hours daily over 3 days to see if it affected amyloid-beta processing, which is linked to Alzheimer's disease. They found no significant changes in the proteins that create these brain plaques. However, the researchers noted that longer-term exposure might produce different results than their short 3-day study.
Zhang JP et al. · 2017
Chinese researchers exposed adolescent mice to cell phone frequency radiation (1.8 GHz) for four weeks and tested their behavior and brain function. While the mice showed no changes in depression, memory, or brain structure, they did display increased anxiety-like behavior and had lower levels of key brain chemicals that regulate mood and brain activity. This suggests that radiofrequency exposure during adolescence may specifically affect anxiety responses in the developing brain.
Benassi B et al. · 2016
Italian researchers exposed brain cells to 50 Hz magnetic fields, then tested their response to a Parkinson's toxin. While EMF alone didn't harm cells, it weakened their antioxidant defenses, making them far more vulnerable to the toxin's damage, suggesting EMF might increase susceptibility to Parkinson's disease.
Calvente I et al. · 2016
Spanish researchers measured radiofrequency electromagnetic field exposure around the homes of 123 ten-year-old boys and tested their cognitive abilities and behavior. Boys living in areas with higher RF exposure (though still below safety guidelines) showed some concerning patterns including lower verbal skills and higher rates of anxiety-related problems. While the study found mostly no effects, the few significant associations raise questions about environmental RF exposure during critical brain development years.
Calvente I et al. · 2016
Spanish researchers measured radiofrequency radiation around the homes of 123 ten-year-old boys and tested their cognitive abilities and behavior. While most measures showed no effects, boys living in areas with higher RF exposure (though still below safety guidelines) had lower verbal skills and higher rates of anxiety-related behaviors compared to those in lower exposure areas. The researchers cautioned that study limitations prevent drawing definitive conclusions.

Researchers exposed pregnant rats to 900 MHz cell phone radiation for 6 hours daily and then tested their offspring's brain function. The exposed offspring showed reduced brain cell activity in the hippocampus (the brain's memory center) and performed worse on learning and memory tests. This suggests that cell phone exposure during pregnancy may impair brain development in offspring.
Erdem Koç G et al. · 2016
Pregnant rats exposed to cell phone radiation (900 MHz) for one hour daily had offspring with fewer brain cells in the hippocampus, the memory center. Melatonin and omega-3 supplements during pregnancy prevented this brain damage, suggesting potential protective strategies for human prenatal development.
Erdem Koç G et al. · 2016
Pregnant rats exposed to cell phone-level radiation (900 MHz) for one hour daily produced offspring with fewer brain cells in the hippocampus, the memory center. However, melatonin and omega-3 supplements during pregnancy prevented this brain damage in the developing babies.
Erdem Koç G et al. · 2016
Turkish researchers exposed pregnant rats to cell phone radiation (900 MHz) for one hour daily throughout pregnancy, then examined brain development in their male offspring. They found that prenatal radiation exposure significantly reduced the number of pyramidal neurons in the hippocampus (a brain region critical for memory and learning). However, when pregnant rats received protective supplements like melatonin or omega-3 fatty acids alongside the radiation exposure, their offspring's brain development remained normal.

Australian researchers measured radiofrequency electromagnetic field (RF-EMF) exposure levels in kindergarten children from cell towers, Wi-Fi, and other wireless sources. They found that environmental exposure levels in kindergarten settings were significantly higher than the personal exposure levels children experienced, with cell tower signals being the dominant source of exposure at levels up to 179 mV/m.

Researchers exposed male mice to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for 4-8 hours daily for 35 days to study effects on sperm production. The radiation caused DNA damage in sperm-producing cells and disrupted the normal development process, resulting in significantly reduced sperm counts. While some recovery occurred after radiation exposure ended, the study demonstrates that RF radiation can impair male fertility through cellular damage.
Odacı E et al. · 2016
Researchers exposed pregnant rats to 900 MHz radiofrequency radiation (the same frequency used by many cell phones) for one hour daily during pregnancy, then examined the reproductive health of their male offspring at 60 days old. The exposed animals showed significantly reduced sperm quality, including lower sperm motility and vitality, along with increased DNA damage and cell death in their testes. This study suggests that EMF exposure during critical developmental periods may have lasting effects on male fertility.

Researchers exposed pregnant rats to cell phone-frequency radiation (900 MHz) for one hour daily during late pregnancy and examined their female offspring's ovaries at 34 days old. The exposed offspring had significantly fewer healthy egg follicles and more damaged, dying follicles compared to unexposed controls. This suggests that EMF exposure during pregnancy may harm the developing reproductive system of female offspring.
Son Y et al. · 2016
Researchers exposed mice genetically modified to develop Alzheimer's-like symptoms to cell phone radiation (1950 MHz) for 3 months to see if it would worsen their memory problems. The radiation exposure at 5 W/kg (about 5 times higher than typical phone use) did not make the mice's memory worse or increase the brain plaques associated with Alzheimer's disease. This suggests that cell phone radiation may not accelerate Alzheimer's progression, at least in this animal model.
Falone S et al. · 2016
Researchers exposed drug-resistant brain cancer cells to pulsed electromagnetic fields (PEMF) at 75 Hz for brief periods over five days, then tested how well the cells handled oxidative stress. The PEMF treatment boosted the cells' antioxidant defenses and reduced harmful reactive oxygen species when challenged with hydrogen peroxide. This suggests that specific electromagnetic field exposures might actually help protect cells from oxidative damage rather than harm them.

Researchers exposed human brain immune cells to magnetic fields at 50 Hz while depriving them of oxygen to mimic stroke conditions. The magnetic field exposure protected cells from dying by reducing harmful calcium and oxidative stress, suggesting potential therapeutic applications for stroke treatment.

Researchers exposed brain cells to extremely low frequency magnetic fields (the type from power lines) at levels as low as 10 microtesla for 24 hours. The study found significant DNA damage in human neuroblastoma cells and increased oxidative stress in rat brain cells. These effects occurred at magnetic field levels that are commonly encountered near electrical appliances and power infrastructure.
(E) Barthélémy A et al. · 2016
French researchers exposed rats to cell phone radiation (900 MHz) for 15-45 minutes and found that even brief exposures caused brain inflammation and memory problems. At exposure levels similar to what heavy cell phone users experience (6 W/kg), rats showed a 119% increase in brain inflammation markers and reduced long-term memory performance. The study demonstrates that radiofrequency radiation can trigger inflammatory responses in the brain that directly impact cognitive function.
Hu Y et al. · 2016
Researchers exposed genetically modified mice with Alzheimer's disease to extremely low frequency magnetic fields (50Hz, 500μT) for three months daily. The magnetic field exposure improved cognitive function, reduced brain cell death, and decreased tau protein abnormalities that are hallmarks of Alzheimer's disease. This suggests that controlled magnetic field exposure might have therapeutic potential for neurodegenerative conditions.
