Researchers exposed pregnant rats to cell phone and Wi-Fi radiation for 60 minutes daily throughout pregnancy and tracked their offspring for multiple generations. They found that this exposure significantly decreased essential reproductive hormones (prolactin, estrogen, and progesterone) in both mothers and offspring, while increasing oxidative stress damage in the uterus. This suggests that everyday wireless radiation exposure during pregnancy could disrupt hormonal balance and reproductive health across generations.

Researchers exposed rats to microwave radiation for 4 hours daily and found it caused oxidative stress and DNA damage in testicular tissue. However, when rats were also given melatonin (a natural hormone), it prevented much of this damage by reducing harmful chemical reactions and protecting genetic material. This suggests melatonin may offer some protection against microwave radiation's harmful effects on reproductive organs.

Researchers exposed young male rats to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwaves) for 3 hours daily over 30 days and found significant damage to their testes. The radiation increased oxidative stress, triggered inflammation, and reduced sperm production in the animals' reproductive organs. However, when rats received gallic acid (a natural antioxidant) alongside the radiation exposure, it protected against much of this testicular damage.

Male rats exposed to cell phone radiation (900 MHz) for one hour daily showed damaged sperm quality, reduced sperm count, and abnormal testicular tissue after seven days. This research suggests that cell phone radiation may harm male fertility in mammals.
Wang D et al. · 2015
Researchers exposed sperm samples from 97 healthy men to cell phone radiation (1950 MHz frequency) for 3 hours at levels similar to what phones emit during calls. The radiation significantly reduced sperm movement and survival rates while increasing cell death and structural defects in sperm heads. This suggests that cell phone radiation can directly damage sperm quality, which could impact male fertility.

Japanese researchers exposed rats to cell phone radiation (2.14 GHz W-CDMA signals) for 20 hours daily across three generations to see if it affected brain development and behavior. They found no abnormalities in brain function, behavior, or general health in any generation of rats, even with continuous exposure from pregnancy through adulthood. The study suggests that this type of cell phone radiation at these exposure levels does not cause harmful effects that pass from parents to offspring.
Shirai T et al. · 2014
Japanese researchers exposed three generations of rats to cell phone signals (2.14 GHz W-CDMA) for 20 hours daily, testing brain function and development across multiple generations. They found no adverse effects on brain function, behavior, or development in any of the three generations studied. This comprehensive multigenerational study suggests that chronic exposure to these specific cell phone frequencies at the tested levels did not cause detectable brain or developmental problems in rats.

Russian researchers exposed pregnant rats and their male offspring to cell phone radiation (897 MHz) for 8 hours daily throughout pregnancy and early development. The exposed male rats showed accelerated sexual development, disrupted sperm production with abnormal cell counts at different stages, and decreased sperm viability despite having more mature sperm overall. This suggests that EMF exposure during critical developmental periods can cause lasting reproductive damage that persists into adulthood.
Sepehrimanesh M et al. · 2014
Researchers exposed male rats to 900 MHz radiofrequency radiation (the same frequency used by many cell phones) for 1, 2, or 4 hours daily over 30 days. Rats exposed for 4 hours daily showed significantly decreased testosterone levels and disrupted reproductive hormones compared to unexposed rats. This suggests that prolonged RF exposure may interfere with male fertility and reproductive function.

Researchers exposed male rats to cell phone radiation (900 MHz) for 1-4 hours daily over 30 days and analyzed changes in testicular proteins. They found 13 proteins that appeared or disappeared after exposure, including stress-response proteins like heat shock proteins and antioxidant enzymes. This suggests that even moderate cell phone-level radiation triggers cellular stress responses in reproductive tissue.

Egyptian researchers exposed rats to 900 MHz radiation from a mobile phone base station for 8 weeks and found it caused oxidative stress (cellular damage from unstable molecules) and disrupted cholesterol levels and antioxidant enzymes. When rats were also given sesame oil during exposure, many of these harmful effects were reduced, suggesting the oil's antioxidants provided some protection against the radiation damage.
Karaman MI et al. · 2014
Researchers exposed rats to cell phone electromagnetic waves for 8 hours daily over 20 days and examined their testicular tissue. Both exposure groups showed significant damage to sperm-producing cells, including abnormal tubules and reduced sperm cell development, compared to unexposed controls. This suggests that prolonged cell phone radiation exposure may harm male reproductive health and fertility.

Researchers exposed healthy men's sperm samples to mobile phone radiation for 5 hours and compared them to unexposed samples. The exposed sperm showed significantly reduced swimming ability and increased DNA damage (fragmentation of genetic material). This suggests that cell phone radiation can directly harm sperm quality, which could impact male fertility.
Geronikolou S et al. · 2014
Researchers exposed fruit flies (Drosophila) to radiation from both mobile phones (900 MHz) and cordless phones (1880 MHz) to study reproductive effects. They found that mobile phone radiation significantly reduced egg laying in the second generation of flies, while cordless phone radiation showed only limited effects. The study suggests that lower frequency radiation may cause stronger biological impacts.
Azadi Oskouyi E et al. · 2014
Researchers exposed male rabbits to 950 MHz microwave radiation (similar to older mobile phone frequencies) for 2 hours daily over 2 weeks. They found that the radiation caused significant damage to the epididymis (part of the male reproductive system), including tissue shrinkage, reduced testosterone levels at higher power, and increased cell death. This suggests that microwave radiation from mobile devices could potentially harm male fertility.
Sepehrimanesh M, Kazemipour N, Saeb M, Nazifi S. · 2014
Researchers exposed male rats to cell phone radiation (900 MHz) for 1-4 hours daily over 30 days, then analyzed protein changes in testicular tissue. They found significant alterations in 13 proteins, including heat shock proteins and antioxidant enzymes that typically respond to cellular stress. These changes suggest that even moderate cell phone radiation exposure can trigger stress responses in reproductive tissue without heating effects.

Researchers exposed male rats to electromagnetic radiation from 3G mobile phones to study effects on reproductive health. They found significant damage including reduced sperm count, DNA damage in sperm cells, and decreased testicular weight. The findings suggest that mobile phone radiation may harm male fertility.
Cetin H et al. · 2014
Researchers exposed pregnant rats to cell phone radiation (900 and 1800 MHz) daily and found it reduced protective antioxidants in the brain and liver while increasing harmful iron levels. This suggests cell phone radiation may damage developing brains during pregnancy and early development.
Tas M et al. · 2014
Turkish researchers exposed male rats to 900 MHz cell phone radiation for 3 hours daily over one full year to study reproductive effects. While sperm count and movement weren't affected, the radiation caused structural damage to testicular tissue, including thinner protective layers and lower tissue health scores. This suggests that chronic cell phone radiation exposure may harm male reproductive organs even when basic sperm parameters appear normal.

Researchers exposed male mice to 2.45-GHz microwave radiation (the same frequency used by Wi-Fi and microwaves) for 2 hours daily over 30 days at very low power levels. The exposed mice showed significant decreases in sperm count and viability, reduced testosterone levels, and damaged reproductive tissue. The study suggests these effects occur through oxidative stress, where radiation generates harmful free radicals that damage cells.
Qin F et al. · 2014
Researchers exposed male rats to cell phone radiation (1800 MHz) for 2 hours daily over 32 days and found it disrupted their natural body clocks and harmed reproductive function. The radiation reduced testosterone levels, decreased sperm production and movement, and interfered with the normal daily rhythms that regulate these processes. This suggests that the timing of EMF exposure throughout the day may influence how severely it affects male fertility.
