Turkish researchers exposed rats to cell phone radiation at 900 MHz and 1800 MHz frequencies for 20 minutes and measured how much dye leaked through the blood-brain barrier. They found that both frequencies increased brain barrier permeability in male rats, with 1800 MHz showing stronger effects, while female rats showed different response patterns.

Researchers exposed SH-SY5Y cells to an extremely low frequency magnetic field set up to reproduce environmental prolonged exposure to ELF-MF (50 Hz, 1 mT) and then treated the cells with the pro-Parkinson's toxin MPP+. ELF-MF alone did not affect cell survival, shape, or morphology, but it did significantly impair redox homeostasis and thiol content, triggering an increase in protein carbonylation. When MPP+ was added to ELF-MF-exposed cells, toxicity was highly enhanced, with significant increases in ROS levels, oxidative damage, and caspase-dependent apoptosis. Pre-incubation with the thiol antioxidants N-acetyl-L-cysteine and GSH ethyl-ester significantly reduced oxidative damage and protected cells from death caused by the combined ELF-MF/MPP+ treatment.

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 used an exposimeter to measure radiofrequency radiation across 20 bands from 88 to 5,850 MHz at Stockholm Central Railway Station. They recorded 1,669 data points and found a median total exposure of 921 μW/m2 with mean levels varying between 2,817 and 4,891 μW/m2 per walking round. High mean measurements were observed for GSM + UMTS 900 downlink and UMTS 2100 downlink, and almost all levels exceeded the BioInitiative precautionary target of 3–6 μW/m2.

Researchers exposed young male rats to 2.45 GHz microwave radiation (WiFi frequency) for 3 hours daily over 30 days and found significant damage to testicular tissue, including increased oxidative stress, inflammation, and reduced sperm production. The antioxidant gallic acid helped protect against these harmful effects when given alongside the radiation exposure.

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.

Researchers established seven groups of pregnant rats and exposed some to 900 MHz EMF for 60 minutes per day during the gestation period. After birth, male rat pups were selected and the total number of pyramidal neurons in the hippocampal region was counted using the optical fractionator technique. The total number of pyramidal cells in the EMF group was significantly lower than in the control, sham, EMF plus melatonin, and EMF plus omega-3 groups. No difference was observed between any groups in terms of rats' body or brain weights.

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.

Researchers exposed pregnant rats to 900 MHz electromagnetic fields (similar to early cell phone frequencies) for one hour daily during late pregnancy. When the offspring reached 60 days old, males showed significantly damaged sperm quality, increased DNA damage, and widespread cell death in their reproductive organs compared to unexposed controls.

Turkish researchers exposed pregnant rats to 900 MHz electromagnetic fields (similar to 2G cell phone frequencies) for one hour daily during late pregnancy. When the offspring reached 60 days old, males showed significantly damaged sperm quality, including reduced motility and vitality, plus increased DNA damage and cell death in their reproductive organs. This suggests prenatal EMF exposure may have lasting effects on male fertility.

This study examined the effects of prenatal exposure to continuous 900-MHz electromagnetic fields on ovarian development in female rat pups. Exposure during pregnancy (days 13-21) resulted in decreased numbers of primordial and tertiary follicles, increased atretic follicles and apoptosis, and histopathological changes including follicle degeneration and stromal fibrosis in the ovaries of prepubertal offspring.

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.

Pregnant rats were exposed to 900 MHz EMF for 1 hour each day during days 13 to 21 of pregnancy. At 60 days old, offspring showed higher apoptotic index, greater DNA oxidation levels, and lower sperm motility and vitality compared to controls. Histopathological examination revealed immature germ cells in seminiferous tubule lumen and altered seminiferous tubule epithelium and structure. TUNEL staining showed nuclear changes indicating apoptosis with large numbers of apoptotic cells in most seminiferous tubule epithelium.

Turkish researchers exposed female rats to 3G cell phone radiation (2100 MHz) for either 10 or 40 days and measured DNA damage in their brains. They found increased DNA damage after 10 days of exposure, but surprisingly, the damage decreased after 40 days, suggesting the brain may develop protective responses to chronic radiation exposure.

Turkish researchers exposed pregnant rats to 900 MHz electromagnetic fields (similar to cell phone radiation) for one hour daily during pregnancy days 13-21. When they examined the female offspring at 32 days old, they found significantly fewer Purkinje cells in the cerebellum and signs of brain cell damage. This suggests that EMF exposure during pregnancy can cause lasting brain development problems in offspring.

Researchers exposed pregnant Sprague Dawley rats to continuous 900-MHz EMF for one hour daily on gestational days 13-21. Female offspring were evaluated on postnatal day 34 for ovarian follicle counts and histopathology. Exposed offspring showed significantly fewer primordial and tertiary follicles and more atretic follicles and higher apoptotic index than controls. Histopathology revealed severe follicle degeneration, vasocongestion, increased stromal fibrotic tissue, and cytoplasmic vacuolization in granulosa cells.

Turkish researchers exposed adolescent male rats to 900 MHz electromagnetic fields (similar to 2G cell phone radiation) for one hour daily during a critical development period. The study found significant damage to spinal cord tissue, including deteriorated myelin sheaths and increased oxidative stress markers. This suggests that EMF exposure during adolescence may harm the developing nervous system.

Researchers exposed 5xFAD mice to 1950 MHz RF-EMF at 5 W/kg SAR for 2 hours daily, 5 days a week, for 3 months. They used Y-maze, Morris water maze, and novel object recognition tests to assess spatial and non-spatial memory. They also measured Aβ deposition, APP and CTFβ levels in hippocampus and cortex, and plasma Aβ peptides. The 3-month exposure did not affect Aβ-related memory impairment or Aβ accumulation.

Researchers exposed SK-N-BE(2) drug-resistant human neuroblastoma cells to a pulsed electromagnetic field and then challenged the cells with hydrogen peroxide to measure oxidative stress responses. The PEMF increased MnSOD-based antioxidant protection and reduced ROS production in response to a pro-oxidant challenge. The researchers suggested their work might lay foundation for the development of non-invasive PEMF-based approaches aimed at elevating endogenous antioxidant properties in cellular or tissue models.
