Exploring the impact of environmental factors on male reproductive health through epigenetics

Research RF Safe Research Library Jan 1, 2025

This narrative review discusses how environmental factors may affect male reproductive health through epigenetic mechanisms, including DNA methylation, histone modifications, chromatin remodeling, and non-coding RNA regulation. It reports that electromagnetic radiation, particularly from mobile phones and wireless devices, is linked in the reviewed literature to reduced sperm count and motility, increased oxidative stress, and chromatin damage. The authors conclude there is a substantive connection between EMF exposure and adverse male reproductive outcomes and suggest practical risk-reduction guidance.

Potential Impacts of Radiofrequency Electromagnetic Fields on the Central Nervous System, Brain Neurotransmitter Dynamics and Reproductive System

Research RF Safe Research Library Jan 1, 2025

This review discusses potential impacts of radiofrequency electromagnetic fields from technologies such as Wi‑Fi and mobile phones on the central nervous system, neurotransmitter dynamics, and reproductive health. It describes proposed mechanisms including oxidative stress, thermal effects, altered neurotransmitter activity, ion channel changes, and neuronal apoptosis, while acknowledging conflicting evidence. The authors note that Wi‑Fi RF exposure has not been confirmed to exceed safety guidelines but argue that updated standards and long-term studies are needed, particularly for children/adolescents and in the context of expanding technologies such as 5G.

5G EMF Exposure at 3.6 GHz in Greece Using Data From Frequency-Selective Monitoring Sensors

Research RF Safe Research Library Jan 1, 2025

This exposure-assessment study analyzed two years of continuous frequency-selective monitoring from 13 sensors in the five largest cities in Greece, focusing on the 3.6 GHz 5G band. It reports a gradual increase in 3.6 GHz environmental EMF levels over time and greater variability than legacy cellular bands, with 30-minute averaging reducing observed fluctuations. Despite the upward trend and variability, all measurements were reported to remain well below Greek and ICNIRP reference levels, and the authors emphasize the value of continuous monitoring as 5G deployment expands.

Electromagnetic fields regulate iron metabolism: From mechanisms to applications

Research RF Safe Research Library Jan 1, 2025

This review synthesizes evidence that electromagnetic field (EMF) exposure is associated in the literature with changes in systemic and cellular iron metabolism, with reported effects varying by EMF parameters, exposure duration, and biological context. It proposes mechanistic pathways involving iron-containing proteins/tissues, membrane and ion channel modulation, and reactive oxygen species (ROS). The authors frame iron-metabolism modulation as relevant to both therapeutic applications and safety evaluation, while emphasizing inconsistencies and the need for standardized exposure protocols.

Single exposure to near-threshold 5G millimeter wave modifies restraint stress responses in rats

Research RF Safe Research Library Jan 1, 2025

In a rat experiment (n=59), a single 40-minute whole-body 28 GHz exposure at near-threshold WBA-SAR levels was evaluated under normal and heat conditions with restraint. After accounting for sham-related restraint stress, exposure was associated with increased serum-free corticosterone 1–3 days later, especially when rectal temperature rose by >1°C. Urinary catecholamines suggested an immediate inhibitory effect on stress response (notably noradrenaline), with heat amplifying effects and linking noradrenaline to tail surface temperature.

Longer cell phone call duration during pregnancy was reported to be associated with higher risk of miscarriage, abnormal birth weight, and abnormal newborn height. Increased cordless phone use was also reported to be linked to abnormal birth weight, while other outcomes were assessed but not described as significantly associated in the abstract.

Effects of Mobile Electromagnetic Exposure on Brain Oscillations and Cortical Excitability: Scoping Review

Research RF Safe Research Library Jan 1, 2025

This scoping review evaluates evidence on mobile phone electromagnetic exposure and its effects on brain oscillations and cortical excitability in healthy individuals. Across 78 EEG studies (and 2 TMS studies), the authors report that exposure may be linked to changes in neural activity, including increased amplitudes in several EEG bands and possible changes in cortical silent period. However, substantial methodological inconsistency across studies limits firm conclusions, and the review highlights limited evidence for 5G/mmWave exposures and argues for precaution and potential guideline revision.

Impact of expectancy on fatigue by exposure to the fifth generation of mobile communication signals

Research RF Safe Research Library Jan 1, 2025

This randomized sham-controlled study in 21 healthy participants tested whether routine-level 5G RF-EMF exposure affects fatigue and EEG power, while manipulating expectancy via correct, false, or no information about exposure order. The study reports no change in EEG power with real versus sham exposure. However, self-reported fatigue varied with the conveyed information about being exposed, suggesting an expectancy/psychological priming effect on symptom reporting.

Determining the relationship between mobile phone network signal strength and RF-EMF exposure: protocol and pilot study to derive conversion functions

Research RF Safe Research Library Jan 1, 2025

This protocol and pilot study evaluated whether smartphone signal strength indicators can be converted into RF-EMF exposure estimates using derived formulas and regression models. The study reports a positive log-linear association between LTE RSSI and far-field (base station) exposure aggregated by location, while handset-related exposure at the ear and chest during data transmission showed negative log-linear trends with improving signal quality. The authors conclude the ETAIN 5G-Scientist app may support large-scale RF-EMF exposure assessment, but emphasize the need for more data to improve accuracy and address uncertainties in individual measurements.

Research RF Safe Research Library Jan 1, 2025

This biophysics study used molecular dynamics simulations to examine how terahertz electromagnetic fields affect ion permeation in voltage-gated potassium (Kv1.2) and sodium (Nav1.5) channels. The simulations report increased ion permeability at several specific terahertz frequencies, with effects depending on field frequency and direction and increasing with field amplitude. The authors frame these results as evidence of specific EMF–ion channel interactions with potential health relevance and possible biomedical applications.

Residential exposure to magnetic field due to high-voltage power lines and childhood leukemia risk in mainland France - GEOCAP case-control study

Research RF Safe Research Library Jan 1, 2025

This French GEOCAP registry-based case-control study evaluated childhood acute leukemia risk in relation to residential proximity to high-voltage overhead power lines and modeled ELF magnetic-field exposure. It reports an increased risk for children under 5 living within 50 m of power lines, particularly when restricting to high-quality geocoded addresses. However, modeled ELF-MF exposure >0.3 µT was not associated with increased risk, and the authors suggest proximity may capture other factors and call for further research and precaution.
