Researchers followed 2,618 Dutch children to see if mothers' cell phone and cordless phone use during pregnancy affected their children's behavior at age 5. They found no significant link between prenatal phone exposure and behavioral problems, whether reported by teachers or mothers. The study suggests that maternal phone use during pregnancy does not increase the likelihood of behavioral issues in young children.
Guxens M et al. · 2013
Dutch researchers studied whether pregnant mothers using cell phones or cordless phones would have children with more behavioral problems at age 5. They followed 2,618 children and found no significant increase in behavioral issues among children whose mothers used phones during pregnancy, even with heavy phone use of 5 or more calls per day. The study suggests that prenatal phone exposure doesn't appear to cause behavioral problems in young children.

Researchers exposed pregnant rabbits and their offspring to 1800 MHz cell phone radiation (similar to GSM signals) for short periods daily. They found that this exposure caused oxidative stress and altered blood chemistry in the infant rabbits, with different effects in males versus females. This suggests that developing animals may be particularly vulnerable to radiofrequency radiation during critical growth periods.
Orhan Baş et al. · 2013
Researchers exposed pregnant rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) during a critical brain development period and found significant loss of brain cells in the hippocampus region of their female offspring. The exposed rat pups had fewer pyramidal cells in the cornu ammonis, a brain area crucial for memory and learning. This suggests that EMF exposure during pregnancy may harm developing brains, potentially affecting cognitive function later in life.
İkinci A et al. · 2013
Researchers exposed pregnant rats to 900 MHz electromagnetic fields (the same frequency used by many cell phones) for one hour daily during late pregnancy. The female offspring showed significant learning and memory problems in maze tests, plus visible damage to the hippocampus, the brain region crucial for learning and memory. This suggests that EMF exposure during pregnancy may harm developing brains in ways that persist after birth.

Researchers exposed pregnant rats to 900-MHz mobile phone radiation for 6 hours daily throughout pregnancy and studied the brain development of their offspring. While the young rats showed no obvious behavioral problems, detailed electrical measurements revealed that specialized brain cells called Purkinje neurons (which help control movement and coordination) had altered electrical activity. This suggests that prenatal cell phone exposure can affect brain development at the cellular level, even when outward behavior appears normal.

Researchers exposed pregnant rats to 900MHz cell phone radiation for three hours daily throughout pregnancy and found significant brain damage in both mothers and offspring, including swollen brain cells and reduced antioxidant defenses. However, when rats were given vitamin E supplements during pregnancy, the protective antioxidant largely prevented this brain damage. This suggests that EMF exposure during pregnancy can harm developing brains, but certain nutrients may offer protection.
Ersan Odacı et al. · 2013
Researchers exposed pregnant rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for one hour daily during late pregnancy, then examined the spinal cord development and motor behavior of their female offspring. The exposed rat pups showed pathological changes in their spinal cord tissue and unexpectedly increased motor activity on behavioral tests. This suggests that prenatal EMF exposure can alter nervous system development in ways that persist after birth.

Turkish researchers studied 500 pregnant women to see if using electronic devices affected birth outcomes. They found that mothers who used mobile phones or computers during pregnancy were significantly more likely to deliver prematurely (before 37 weeks), though device use didn't affect birth weight. The study suggests everyday EMF exposure from common devices may influence pregnancy duration.
Ozorak A et al. · 2013
Turkish researchers exposed pregnant rats and their offspring to Wi-Fi (2.45 GHz) and mobile phone frequencies (900 and 1800 MHz) for one hour daily from pregnancy through 6 weeks of age. The exposed animals showed significant oxidative damage in kidneys and reproductive organs, with increased harmful byproducts and decreased protective antioxidants. This suggests that common wireless radiation may interfere with normal development and damage vital organs during critical growth periods.
Ozgur E et al. · 2013
Researchers exposed pregnant rabbits and their offspring to cell phone-like radiation (1800 MHz GSM) for 15 minutes daily and measured blood chemistry changes in the baby rabbits. They found that even brief daily exposures caused oxidative stress (cellular damage from free radicals) and altered blood chemistry parameters, with different effects in male versus female offspring. The findings suggest that developing animals may be particularly vulnerable to radiofrequency radiation during critical growth periods.
İkinci A et al. · 2013
Researchers exposed pregnant rats to 900 MHz electromagnetic fields (the same frequency used by many cell phones) for one hour daily during late pregnancy, then tested the learning abilities of their female offspring. The exposed pups showed significantly impaired learning and memory performance on standard tests, along with visible damage to brain tissue in the hippocampus, a region critical for learning and memory.
Gao X, Luo R, Ma B, Wang H, Liu T, Zhang J, Lian Z, Cui X · 2013
Pregnant rats exposed to 900MHz cell phone radiation for three hours daily showed brain damage in mothers and offspring, including cellular swelling and reduced antioxidant defenses. Vitamin E supplements prevented most damage, suggesting antioxidants may protect developing brains from EMF-related oxidative stress during pregnancy.
Tsybulin O et al. · 2013
Researchers exposed developing quail embryos to cell phone radiation at extremely low power levels (1000 times weaker than typical phone exposure) and found dramatically different effects depending on exposure duration. Short exposure (38 hours) actually stimulated development and reduced DNA damage, while longer exposure (158 hours) stunted development and increased DNA damage. This reveals that EMF effects aren't simply dose-dependent but follow complex biological patterns.
Hancı H et al. · 2013
Researchers exposed pregnant rats to cell phone-level radiation (900 MHz) for one hour daily during late pregnancy, then examined the testicles of their male offspring at 21 days old. The exposed offspring showed significant damage to their developing reproductive organs, including structural abnormalities, increased cell death, and DNA damage that persisted weeks after birth. This suggests that EMF exposure during pregnancy may harm the reproductive development of male offspring.
Odacı E et al. · 2013
Researchers exposed pregnant rats to cell phone radiation (900 MHz) daily during late pregnancy. Their offspring showed spinal cord damage and increased motor activity compared to unexposed pups, suggesting prenatal EMF exposure can disrupt normal nervous system development.
Haghani M, Shabani M, Moazzami K · 2013
Pregnant rats exposed to cell phone radiation (900 MHz) for six hours daily produced offspring with altered brain function. While the young rats behaved normally, their Purkinje neurons (cells controlling movement and learning) showed reduced electrical activity, suggesting prenatal exposure affects developing brain circuits.
Baş O et al. · 2013
Researchers exposed pregnant rats to cell phone frequency radiation (900 MHz) for one hour daily during a critical brain development period and examined their female offspring at 32 days old. They found significant loss of pyramidal neurons in the hippocampus, a brain region crucial for learning and memory. This suggests that prenatal EMF exposure during critical development windows may cause lasting brain damage that persists into later life.
Poulletier de Gannes F et al. · 2012
French researchers exposed pregnant rats to Wi-Fi signals (2.45 GHz) for 2 hours daily during pregnancy to test whether this radiation could harm developing babies. They found no birth defects, developmental problems, or other harmful effects in the rat pups, even at the highest exposure level tested (4 W/kg). This study suggests that Wi-Fi exposure during pregnancy may not cause developmental harm at levels tested.
Laudisi F et al. · 2012
Italian researchers exposed pregnant mice to WiFi signals (2.45 GHz) at high levels for 2 hours daily throughout pregnancy to study effects on their offspring's immune system development. They found no detrimental effects on T cell development, immune cell counts, or immune function in the offspring at either 5 weeks or 26 weeks of age. This suggests that prenatal WiFi exposure may not harm developing immune systems, though the study used exposure levels much higher than typical human exposure.
Panagopoulos DJ · 2012
Researchers exposed fruit flies to cell phone radiation (GSM) and found that exposed females developed significantly smaller ovaries compared to unexposed flies. The radiation caused DNA damage and cell death in egg chambers, disrupting normal reproductive development. This suggests that wireless radiation may interfere with reproductive processes in biological systems.

Researchers exposed pregnant rats to cell phone radiation for different durations (10, 30, or 60 minutes, three times daily) throughout their pregnancies and then examined the brain chemistry of their offspring. They found that longer exposures caused significant oxidative stress (cellular damage from free radicals) and altered neurotransmitter levels in the fetal brains. The study suggests that prenatal cell phone radiation exposure may harm developing brain tissue.
Ingole IV, Ghosh SK. · 2012
Researchers exposed developing chick embryos to cell phone radiation and examined the effects on nerve cells in the spinal cord area (dorsal root ganglion neurons). They found that exposure caused dose-dependent damage to these developing nerve cells, meaning higher doses caused more damage. The damage persisted even when researchers gave the embryos breaks between exposures, suggesting the effects weren't easily reversed.

Researchers exposed pregnant mice to cell phone radiation (800-1900 MHz) and found their offspring showed hyperactivity and memory problems as adults. Brain recordings revealed altered development in the prefrontal cortex, the brain region responsible for attention and memory. This is the first experimental evidence that prenatal cell phone exposure can cause lasting behavioral and brain changes.

Researchers exposed pregnant mice and newborn mice to 50-Hz electromagnetic fields (the same frequency used in electrical power systems) for five days and then tested their motor coordination skills. They found that mice exposed during pregnancy showed significant learning deficits when tested on a rotating rod device, while mice exposed only after birth showed no such problems. This suggests that developing brains may be particularly vulnerable to EMF exposure during the prenatal period.
