The study also examined whether melatonin or omega-3 supplements could protect against these effects, but found limited benefits.

The effect on rat peripheral nerve morphology and function of a 900-MHz electromagnetic field applied in the prenatal period

Hancı H, Yenilmez E, Demir S, Yıldırım M, Gedikli Ö, Kaya H · 2025

Researchers exposed pregnant rats to 900 MHz electromagnetic fields (similar to cell phone radiation) for one hour daily throughout pregnancy. They found that this prenatal EMF exposure caused lasting damage to peripheral nerve development in the offspring, with structural changes still visible when the rats reached adulthood. While nerve function wasn't completely impaired, the study demonstrates that EMF exposure during pregnancy can cause permanent developmental changes.

Effects of 1800 MHz and 2100 MHz mobile phone radiation on the blood-brain barrier of New Zealand rabbits

Unknown authors · 2025

Researchers used 21 New Zealand rabbits divided into three groups of seven, with a control group and two groups exposed to 1800 MHz and 2100 MHz radiation. Exposure was maintained at a constant power intensity of 15 dBm for 38 minutes per day under non-thermal conditions with RF levels about ten times lower than normal. Blood-brain barrier permeability was assessed by measuring Evans blue dye in brain tissue using spectrophotometry at 620 nm. No statistically significant difference was found for 1800 MHz exposure, but 2100 MHz exposure produced a statistically significant difference at the 95% confidence level with a decrease in EB values.

Repeated Head Exposures to a 5G-3.5 GHz Signal Do Not Alter Behavior but Modify Intracortical Gene Expression in Adult Male Mice

Unknown authors · 2025

Researchers exposed mice to 5G signals at 3.5 GHz for six weeks, finding no changes in behavior, memory, or anxiety levels. However, the radiation did alter gene expression in brain cells, particularly affecting genes related to brain communication pathways. The study shows 5G can cause biological changes even when behavioral effects aren't obvious.

Possible effects of radiofrequency electromagnetic radiation on contextual fear conditioning, hippocampal perivascular space, apoptosis and adrenal gland microarchitecture in rats

Narayanan SN et al. · 2025

Male albino Wistar rats aged four weeks were exposed to 900 MHz radiation from a cellphone for four weeks at one hour per day. In the contextual fear conditioning test, the RF-EMR exposed group showed considerably elevated bright and dark compartment transitions and a significant decrease in latency to enter the dark compartment. Apoptosis was apparent in the CA3 region and perivascular space was significantly increased in the hippocampus of the radiation-exposed group. Lymphocytic infiltrates, congested sinusoids, and apoptotic-like changes were evident in the zona fasciculata, while the cytoarchitecture of the adrenal medulla was comparable in all three groups.

5G Radio-Frequency-Electromagnetic-Field Effects on the Human Sleep Electroencephalogram: A Randomized Controlled Study in CACNA1C Genotyped Volunteers

Unknown authors · 2025

Swiss researchers exposed 34 people to 5G signals (3.6 GHz and 700 MHz) for 30 minutes before sleep and monitored their brain waves during sleep. They found that people with a specific genetic variant showed altered brain wave patterns (faster sleep spindles) only when exposed to 3.6 GHz 5G radiation. This suggests that genetic differences may determine how sensitive individuals are to 5G's effects on brain activity during sleep.

The influence of Wi-Fi on the mesonephros in the 9-day-old chicken embryo

Unknown authors · 2025

Researchers exposed 9-day-old chicken embryos to Wi-Fi radiation (2.4 GHz) for the entire incubation period and found cellular damage in developing kidney tissue. While overall organ development appeared normal, the radiation caused degenerative changes, increased cell death, and altered gene expression in the mesonephros (embryonic kidney). This suggests Wi-Fi radiation can disrupt normal tissue development even at low power levels.

Possible effects of melatonin and omega-3 on the obesity-related hypothalamic nuclei of the electromagnetic field-exposed offspring rats: a stereological and immunohistochemical analysis

Altun G, Kaplan S · 2025

This study exposed pregnant rats to 900 MHz cell phone radiation (similar to 2G/3G frequencies) for 2 hours daily throughout pregnancy, then examined brain changes in their male offspring. Researchers found fewer neurons in key appetite-control brain regions, increased anxiety behaviors, and altered expression of genes linked to obesity. Neither melatonin nor omega-3 supplements protected against these effects.

Greater prevalence of symptoms associated with higher exposures to mobile phone base stations in a hilly, densely populated city in Mizoram, India

Sailo L et al. · 2025

Researchers gave a symptom questionnaire to 183 highly exposed and 126 reference residents matched on demographics in a hilly city in Mizoram, India. They measured RF-EMF levels in residents' lounge rooms and compared symptoms between those living closer than 300 meters and farther than 400 meters from base stations. Residents living closer reported more symptoms in all four health categories, and higher exposure levels were the only factor predicting the number of symptoms.

Oxidative stress and testicular damage induced by chronic exposure to 35.5 GHz millimeter wave radiation in male Wistar rats

Gautam R, Jha N, Tomar AK, Nirala JP, Arora T, Rajamani P · 2025

The exposed group received 35.5 GHz millimeter wave radiation for 2 hours per day over 60 days. Exposure significantly reduced sperm viability and count and caused morphometric changes in testicular tissue. Lipid peroxidation increased while superoxide dismutase, total sulfhydryl levels, and total antioxidant capacity decreased in exposed rats. DNA damage measured by comet assay was significantly increased in the exposed group.

Researchers exposed rats to 5.9 GHz 5G radiation for 2 hours daily for 30 days and found significant damage to testicular tissue, including loss of sperm cells and increased cellular stress markers. When rats were also given coenzyme Q10 supplements, the testicular damage was largely prevented. This suggests 5G frequencies may harm male reproductive health through oxidative stress.

Can Theta Burst Electromagnetic Fields Disrupt Learning in Planaria? Evidence of Impaired Fear-Conditioned Responses

Unknown authors · 2025

Researchers exposed planaria to a theta burst electromagnetic field of 1 μT intensity and 100 Hz bursts in a T-maze with an aversive light stimulus. Planaria that received only the light stimulus learned to avoid the associated maze arm, shown by a significant decrease in preferred arm selections. Planaria exposed to the electromagnetic field before or after light exposure did not show this learning, as their arm selections remained stable.
