Researchers exposed mouse sperm cells to 50 Hz power line frequency electromagnetic fields at different intensities for 72 hours. They found that low-intensity exposure (1 mT) decreased DNA methylation while high-intensity exposure (3 mT) increased it, suggesting EMF can alter how genes are regulated in reproductive cells. These epigenetic changes could potentially affect sperm function and fertility.
Li Y, Wang X, Yao L · 2015
This study investigated how oligodendrocyte precursor cells (OPCs) respond to applied electric fields, finding that OPCs migrate toward the anode (positive electrode) with increased directedness at higher field strengths (50-200 mV/mm), while migration speed remained unchanged. Transcriptional analysis revealed that the mitogen-activated protein kinase pathway, which signals cell migration, was significantly upregulated at 200 mV/mm, suggesting electric fields can guide OPC migration through specific genetic mechanisms relevant to neural regeneration.

Researchers exposed bone marrow stem cells from rats and mice to 50 Hz electromagnetic fields (the same frequency as power lines) for several days. The EMF exposure increased stem cell growth and boosted production of immune-signaling molecules. The study found these EMF-stimulated stem cells also enhanced the growth and movement of immune cells when their secretions were tested.
Bertea et al. · 2015
Italian researchers exposed Arabidopsis plants to artificially reversed Earth's magnetic field conditions using specialized coil systems. They found that reversing magnetic polarity significantly altered plant growth patterns and changed the expression of genes involved in stress response and antioxidant systems. This supports the theory that magnetic field reversals throughout Earth's history may have driven plant evolution.
Al-Huqail AA, Abdelhaliem E · 2015
Researchers exposed maize seedlings to extremely low frequency (ELF) electric fields for varying time periods and analyzed the genetic damage. They found significant changes to proteins, enzymes, and DNA structure, with the most severe damage occurring after 5 days of exposure. The study demonstrates that longer EMF exposure periods cause increasing genetic stress in plant cells.
Zheng F et al. · 2015
This cross-sectional study of 746 Chinese schoolchildren examined connections between mobile phone use and self-reported health symptoms. Researchers found that children using phones longer each day and for more years experienced significantly higher rates of fatigue, with those making longer daily calls nearly three times more likely to report exhaustion. The findings suggest that even in children, mobile phone exposure correlates with measurable wellness impacts.
De Amicis A et al. · 2015
Researchers exposed human fetal cells to terahertz (THz) radiation at 0.1-0.15 THz frequencies and found chromosome damage without DNA breaks. The study revealed increased micronuclei formation and abnormal cell structure changes, suggesting THz radiation can cause chromosomes to separate incorrectly during cell division.

Researchers exposed rats to Wi-Fi radiation (2.4 GHz) 24 hours daily for one full year and found significant changes in brain microRNA expression. Two specific microRNAs decreased by over 3 times compared to unexposed rats. The researchers concluded this could contribute to neurodegenerative diseases.
Megha et al. · 2015
Researchers exposed rats to low-level microwave radiation at cell phone frequencies (900, 1800, and 2450 MHz) for 60 days and found significant brain damage. The radiation caused oxidative stress, inflammation, and DNA damage in brain tissue, with effects becoming more severe at higher frequencies.
Zalata A et al. · 2015
Researchers exposed human sperm samples from 124 men to cell phone radiation for one hour in laboratory conditions. The radiation significantly reduced sperm movement and increased DNA damage, with the worst effects seen in men who already had fertility problems. This suggests that cell phone radiation may harm male fertility by damaging sperm quality and genetic material.
Sehitoglu I et al. · 2015
Researchers exposed pregnant rats to 900 MHz cell phone radiation for 24 hours daily during pregnancy, then examined the reproductive health of their male offspring at 60 days old. The exposed rats had 13% lower testosterone levels, smaller testes, and increased cell death markers compared to unexposed controls. This suggests that cell phone radiation exposure during pregnancy may harm the developing reproductive system of male offspring.
Sangun O, Dundar B, Darici H, Comlekci S, Doguc DK, Celik S · 2015
Researchers exposed pregnant and newborn female rats to WiFi-frequency radiation (2450 MHz) for one hour daily and tracked their development through puberty. Rats exposed in the womb showed slower growth, delayed puberty, and increased oxidative stress in brain and ovary tissues compared to unexposed controls. This suggests that WiFi radiation during critical developmental periods may disrupt normal reproductive maturation.
Saili L et al. · 2015
Researchers exposed rabbits to WiFi signals (2.45GHz) for one hour and measured their heart function and blood pressure. The WiFi exposure increased heart rate by 22% and blood pressure by 14%, while also disrupting normal heart rhythm patterns. This suggests that common WiFi radiation can directly affect cardiovascular function, even after just brief exposure.
Mahmoudabadi FS, Ziaei S, Firoozabadi M, Kazemnejad A · 2015
Researchers in Iran studied 600 women to examine whether mobile phone use during pregnancy increases the risk of miscarriage. They compared women who had unexplained miscarriages before 14 weeks with those who carried pregnancies past 14 weeks. The study found significant differences in mobile phone usage patterns between the two groups, with higher phone use associated with increased miscarriage risk.
Geronikolou SA et al. · 2015
Researchers studied how children's stress hormone systems respond to cell phone calls after experiencing mental stress. They found that children who regularly use cell phones had different cortisol (stress hormone) patterns compared to occasional users when making a 5-minute phone call after a stressful task. This suggests that frequent cell phone use may alter how young people's bodies handle stress.
Gandhi G, Kaur G, Nisar U. · 2015
Researchers studied 63 people living within 300 meters of a cell phone tower and compared their DNA damage to 28 people living farther away. They found significantly more genetic damage (DNA breaks and mutations) in the blood cells of those living near the tower, where radiation levels exceeded safety limits. Women showed more DNA damage than men, and the amount of damage correlated with how close people lived to the tower and how much they used their phones.
Ulubay M et al. · 2015
Researchers exposed pregnant rats to 900 MHz electromagnetic fields (the frequency used by older cell phones) and examined their offspring's kidneys at four weeks old. They found that prenatal EMF exposure caused the kidneys to grow abnormally larger while reducing the number of glomeruli (tiny filtering units essential for kidney function). Importantly, supplementing with melatonin or omega-3 fatty acids during pregnancy prevented these harmful effects.
Topal Z et al. · 2015
Researchers exposed pregnant rats to cell phone radiation (900 MHz) for one hour daily during the final third of pregnancy, then examined their male offspring at three weeks old. The exposed pups showed significant liver damage, including cellular death and increased oxidative stress markers. This suggests that prenatal exposure to wireless radiation may cause lasting organ damage that persists after birth.
Sokolovic D et al. · 2015
Researchers exposed rats to microwave radiation for 4 hours daily and found it caused oxidative stress and DNA damage in testicular tissue. However, when rats were also given melatonin (a natural hormone), it prevented much of this damage by reducing harmful chemical reactions and protecting genetic material. This suggests melatonin may offer some protection against microwave radiation's harmful effects on reproductive organs.
Olgar Y et al. · 2015
Researchers exposed rats to 2.1 GHz radiofrequency radiation (similar to cell phone frequencies) for 2 hours daily over 10 weeks and studied how their heart muscle cells responded. While the basic heart muscle contractions remained normal, the cells became less responsive to adrenaline-like stress hormones, and nitric oxide levels in the heart increased significantly. This suggests that chronic RF exposure may alter how the heart responds to stress, even when basic heart function appears unchanged.
Odacı E, Özyılmaz C. · 2015
Researchers exposed male rats to 900 MHz electromagnetic fields (the same frequency used by cell phones) for one hour daily over 30 days and found significant damage to testicular tissue and function. The EMF-exposed rats showed structural damage to sperm-producing tubes, increased cell death, and reduced levels of important antioxidants that protect against cellular damage. This suggests that chronic exposure to cell phone-level radiation may harm male reproductive health.
Ma HR, Ma ZH, Wang GY, Song CM, Ma XL, Cao XH, Zhang GH. · 2015
Researchers exposed rats to 900 MHz mobile phone radiation for 4 hours daily over 18 days and found significant liver damage. The radiation caused increased oxidative stress (cellular damage from harmful molecules), liver cell death, and visible tissue damage including cell swelling and death. This suggests that prolonged exposure to mobile phone frequencies may harm liver function through cellular stress pathways.
Hancı H et al. · 2015
Researchers exposed pregnant rats to 900 MHz cell phone radiation for one hour daily and examined the immune organs (spleen and thymus) of their male offspring at 21 days old. The prenatal radiation exposure caused significant oxidative damage and structural abnormalities in these critical immune system organs. This suggests that EMF exposure during pregnancy may compromise immune system development in offspring.
Schoeni A, Roser K, Röösli M · 2015
Swiss researchers followed 439 adolescents for one year to see if cell phone radiation affects memory. They found that teens with higher exposure to radiofrequency electromagnetic fields from mobile phones showed measurably worse performance on figural memory tests (the ability to remember visual patterns and shapes). The effect was stronger when researchers calculated actual radiation dose to the brain rather than just looking at call time.
