The findings suggest phone use may not directly harm male reproductive health, though questions about exposure measurement remain.

Histomorphometry and Sperm Quality in Male Rats Exposed to 2.45 GHz Wi-Fi

Vijay S et al. · 2025

Researchers exposed male rats to 2.45 GHz Wi-Fi radiation for either 4 or 24 hours daily over 8 weeks and found significant damage throughout the reproductive system. The study revealed tissue damage in testes, sperm ducts, and accessory glands, along with reduced sperm count and impaired sperm movement. This comprehensive analysis shows Wi-Fi exposure affects the entire male reproductive system, not just sperm production.

An Evaluation of Neuronal PARP-1 and Caspase-3 Levels in the Brain Tissue of Female Rats Exposed to Electromagnetic Fields at Different Gestational Stages

Unknown authors · 2025

Researchers exposed pregnant rats to 900 MHz EMF radiation (similar to cell phone frequencies) during different stages of pregnancy and examined brain damage in their offspring 28 days after birth. They found that exposure during the final week of pregnancy (days 15-21) caused significant brain cell death in the hippocampus, the brain region critical for learning and memory. This timing coincides with a crucial period of brain development when new neurons are forming.

Unknown authors · 2025

Researchers tracked 1,666 pregnant women in Iran from 2015-2019, measuring their exposure to cell phones, cordless phones, and Wi-Fi devices. Women with longer cell phone call durations during pregnancy showed significantly higher rates of miscarriage, abnormal birth weight, and abnormal infant height. The study found that every additional minute of daily cell phone use increased miscarriage risk by 0.6%.

Men with genetic predisposition face greater fertility challenges when exposed to electromagnetic radiation

Pal S, Paladhi P, Dutta S, Ghosh P, Chattopadhyay R, Ghosh S · 2025

This study examined 708 azoospermic men and 640 controls from West Bengal to investigate whether genetic variants in meiotic regulator genes (SPO11, RNF212, SYCP3) combined with electronic radiation exposure increase azoospermia risk. The researchers found significant associations between these genetic variations and azoospermia, particularly in men aged 30+ with electronic radiation exposure, suggesting radiation may exacerbate meiotic errors and impair fertility in genetically predisposed individuals.

The Effect of 5G Mobile Phone Electromagnetic Exposure on Corticospinal and Intracortical Excitability in Healthy Adults: A Randomized Controlled Pilot Study

Unknown authors · 2025

Researchers exposed 19 healthy adults to 5G phone radiation at 3.6 GHz for 5 and 20 minutes, then measured brain nerve activity using magnetic stimulation. They found no detectable changes in brain excitability or nerve function after either exposure duration. The study suggests any effects from typical 5G phone calls are likely too subtle to measure with current methods.

The CB1R of mPFC is involved in anxiety-like behavior induced by 0.8/2.65 GHz dual-frequency electromagnetic radiation

Unknown authors · 2025

Scientists exposed mice to dual-frequency electromagnetic radiation at 0.8/2.65 GHz (similar to cell phone and WiFi frequencies) and found it caused significant anxiety-like behavior. The radiation disrupted the brain's endocannabinoid system, particularly reducing CB1 receptors in the prefrontal cortex that help regulate emotions. This study provides new evidence that common wireless frequencies may affect mental health through specific brain chemistry changes.

The Role of Glutamatergic Neurons in Changes of Synaptic Plasticity Induced by THz Waves

Unknown authors · 2025

Researchers exposed mouse brain tissue to 1.94 THz (terahertz) waves for one hour and found significant damage to brain cell connections and communication. The study showed these waves reduced the activity of glutamatergic neurons (brain cells that use glutamate for signaling) and impaired synaptic plasticity, which is essential for learning and memory. Artificially stimulating these neurons helped reverse the damage, suggesting potential protective strategies.
