Researchers exposed pregnant rats to 5G EMF at 3500 MHz continuous wave with a whole-body SAR of 0.07 W/kg for 22 hours per day from gestational day 8 to postnatal day 21. Both male and female pups showed delayed incisor eruption by one day in the exposed group compared to sham controls. In adolescent open-field testing, exposed females exhibited 70% fewer stereotyped movements while exposed males exhibited 50% more stereotyped movements than sham-exposed rats.

Researchers exposed male and female Wistar albino offspring to 900 MHz EMF for one hour per day during prenatal (23 days) and/or postnatal (40 days) periods and collected brain and kidney tissues at puberty. In all exposed groups, total oxidant status, IL-2, IL-6, and TNF-α rose while total antioxidant status fell in both sexes' brain and kidney tissues. Renin-angiotensin system components including angiotensinogen, renin, AT1, AT2, and MAS1-like receptor expression were also elevated in all exposed groups compared with controls.

Turkish researchers exposed pregnant rats and their offspring to 900 MHz cell phone radiation (the frequency used by GSM networks) for one hour daily. They found significant increases in inflammation, oxidative stress, and activation of the renin-angiotensin system in both brain and kidney tissues of the young rats. The effects occurred whether exposure happened during pregnancy, after birth, or both periods.

The study used prepubertal male rats exposed to 2.45 GHz RF radiation at varying electric field intensities. The exposure groups included electric field strengths of 0.6, 1.9, 5, 10, and 15 V/m, with daily 1-hour exposures for 45 days. Exposed rats showed elevated malondialdehyde (MDA) and decreased glutathione (GSH) levels in testicular tissue. Histological analysis revealed distinct alterations in testicular tissue compared to controls.

Male Sprague Dawley rats were divided into four groups: control, RFR exposure, paricalcitol treatment, and combined RFR plus paricalcitol. No significant differences were found in seminiferous tubule diameters or germinal epithelial thicknesses among groups. Ultrastructural changes observed in the seminiferous tubule and Leydig cells in the RFR group were decreased in the RFR plus paricalcitol group. The RFR plus paricalcitol group showed increased Johnsen Score, Ki67, p63 immunoreactivity, SOD and CAT activities, and decreased MDA levels compared with the RFR group.

Researchers exposed Chinese hamster ovary cells to a non-toxic dose of 15-nm gold nanoparticles for 48 hours and then to 900 MHz GSM radiofrequency radiation for 24 hours. The conditioned medium from these cells was transferred to new bystander cells, and cell death, DNA breaks, oxidative stress, and COX-2 expression were measured. RFR increased metabolic death in GNP-treated cells, while colony formation was reduced in bystander cells and RFR-exposed cells regardless of GNP presence. ROS levels were significantly lower in GNP-treated cells, but RFR-induced DNA breaks and micronuclei frequencies were not significantly affected by GNP.

Researchers exposed Chinese hamster cells to 900 MHz cell phone radiation in the presence of gold nanoparticles, then transferred the culture medium to unexposed 'bystander' cells. They found that radiation created harmful effects in both directly exposed cells and bystander cells, with gold nanoparticles changing how these effects occurred.

Researchers exposed male rats to 1800 MHz radiofrequency radiation (cell phone frequency) for one hour daily over 30 days, finding it caused testicular damage including cellular changes and increased oxidative stress. When rats received paricalcitol (a vitamin D compound) alongside radiation exposure, the testicular damage was significantly reduced. This suggests certain compounds might help protect reproductive organs from cell phone radiation effects.

Weaned Wistar rats were divided into four groups and exposed to EMF (1,760 MHz, 2 h/day) and/or 15% fructose solution for 8 weeks. In the hypothalamic tissue of the combined exposure group, expressions of SIRT1, FOXO1, p-PI3K, p-AKT, Complex III, UCP2, MnSOD, and catalase and activities of OXPHOS and GSH were significantly decreased compared to the normal, EMF-only, and fructose-only groups. In hepatic tissue of the combined exposure group, expressions of p-AMPKα, SIRT1, FOXO1, IRS1, p-PI3K, Complex I, II, III, IV, V, UCP2, and MnSOD and activities of OXPHOS, SOD, catalase, and GSH were significantly reduced compared to the normal group.

Researchers exposed growing rats to mobile phone radiation (1,760 MHz) and high-fructose diets for 8 weeks, finding that the combination significantly disrupted metabolic regulation in the brain and liver. The dual exposure impaired insulin signaling, mitochondrial function, and antioxidant defenses more severely than either stressor alone. This suggests that common modern exposures may work together to increase metabolic dysfunction risk during critical developmental periods.

Researchers exposed two-week-old immature male chickens to non-thermal low-level 2.45 GHz microwave radiation for two hours per day over 30 days. Exposed chickens showed decreased testicular weight, volume, and gonado-somatic index, as well as a substantial reduction in seminiferous tubule diameter. Radiation exposure increased oxidative stress parameters, increased IL-1β immunoreactivity, decreased IL-10 immunoreactivity, and reduced ERα expression in testes.

Researchers exposed young male chickens to 2.45 GHz microwave radiation (the same frequency as WiFi and microwave ovens) for 2 hours daily over 30 days. The radiation caused testicular shrinkage, increased inflammation, and reduced hormone receptor activity linked to male fertility. This study provides biological evidence that common microwave frequencies may impair reproductive development.

Researchers exposed human HEK293 cultured cells to a 1.8 GHz carrier frequency at amplitudes typical of household telecommunications. ROS concentrations increased significantly after 15 minutes of exposure and were localized to both nuclear and cytosolic compartments. qPCR analysis revealed altered gene expression of anti-oxidative enzymes SOD, GPX, and CAT, and oxidative enzyme Nox-2. Multiple genes responsive to static magnetic fields were also regulated by RF, suggesting common response mechanisms. Many RF effects showed evidence of hormesis with biphasic dose-response curves and blind spots at certain amplitudes.

Researchers exposed human cells to 1.8 GHz radiofrequency radiation (similar to cell phone signals) and found it triggered the formation of harmful reactive oxygen species (ROS) within just 15 minutes. The study revealed that cellular damage doesn't increase linearly with signal strength - instead, certain amplitudes caused no measurable effects while others triggered significant responses. This suggests that even everyday wireless exposures can disrupt normal cellular function through oxidative stress.
