Wi-Fi Decreases Human Sperm Motility And Increases Sperm DNA Fragmentation

Immunohistopathologic Demonstration Of Deleterious Effects on Growing Rat Testes of Radiofrequency Waves Emitted from Conventional Wi-Fi Devices.

OBJECTIVE: To investigate effects on rat testes of radiofrequency radiation emitted from indoor Wi-Fi Internet access devices using 802.11.g wireless standards.
RESULTS: We observed significant increases in serum 8-hydroxy-2'-deoxyguanosine levels and 8-hydroxyguanosine staining in the testes of the experimental group indicating 
DNA damage due to exposure (p < 0.05). We also found decreased levels of catalase and glutathione peroxidase activity in the experimental group, which may have been due to radiofrequency effects on enzyme activity (p < 0.05).
CONCLUSIONS: These findings raise questions about the safety of radiofrequency exposure from Wi-Fi Internet access devices for growing organisms of reproductive age, with a 
potential effect on both fertility and the integrity of germ cells.

Effects of exposure to 2.45 GHZ microwave radiation on male rat reproductive system.
"Conclusion: MW radiation exposures caused reduction in sperm counts and motility and increased the proportion of abnormal sperm cells and induced reduction in sperm count and motility while increasing the proportion of abnormal sperm cells."

Use Of Laptop Computers Connected To Internet Through Wi-Fi Decreases Human Sperm Motility And Increases Sperm DNA Fragmentation
Ex vivo exposure of human spermatozoa to a wireless internet-connected laptop decreased motility and induced DNA fragmentation by a nonthermal effect.”

Effects of Laptop Computers' Electromagnetic Field on Sperm Quality
...magnetic fields induced by laptop computers may decrease sperm count and sperm motility, ultimately affecting male reproductive capabilities. It is advisable to limit the time these devices are used in a laptop position."

Mobile Phone Mast Effects on Common Frog (Rana temporaria) Tadpoles: The City Turned into a Laboratory
In the exposed group, low coordination of movements, an asynchronous growth, resulting in both big and small tadpoles, and a high mortality (90%) was observed. Regarding the control group (n ¼ 70) under the same conditions but inside a Faraday cage, the coordination of movements was normal, the development was synchronous, and a mortality of 4.2% was obtained.”

progressive decrease in the number of newborns per dam was found, which ended in irreversible infertility."

Analyzing The Health Impacts Of Modern Telecommunications Microwaves
The effect of cell death induction in the developing eggs of the exposed female insects, just like the corresponding effect on the reproductive capacity... evident for distances up to 100 cm (radiation intensities down to 1 μW/cm2).”

Lethal And Teratogenic Effects Of Long-Term Low-Intensity Radio Frequency Radiation At 428 Mhz On Developing Chick Embryo
"...for more than 20 days resulted in 
embryolethal and/or teratogenic effects and delayed hatching. These adverse biological effects were not due to any thermal effect of the RF radiation. We have demonstrated teratogenicity in the chick embryo as a result of protracted low-dose RF irradiation." http://onlinelibrary.wiley.com/doi/10.1002/tera.1420430616/abstract "Almost one fourth of dead embryos in the radio frequency group occured within 10 days after incubation and the rest was due to death within the eggshell following inability to hatch... A functional abnormality consisting of creeping movement and inability to stand was found in 89% of exposed embryos, but not in the control group.

Possible Effects of Electromagnetic Fields from Phone Masts on a Population of White Stork (Ciconia ciconia).
Balmori Alfonso (2005).  Electromagnetic Biology and Medicine, 24: 109-119
"Total productivity (number of young per couple, including nests with 0 chicks) for nests within 200m of the antenna was 0.86 (0.7 - 1.02), whereas productivity for nests further than 300m away was 1.6 (1.46- 1.74). Both were statistically significant, with a p value of 0.001. A large part of the difference here appears to be due to the likelihood of the couples in the nests near the mast (cell tower) not having any chicks: 40% of those within 200m had no chicks, whereas in the nests greater than 300m away only 3.3% did not have chicks! Odd behaviour was also noted in the storks, happening much more frequently the closer the nests were to the masts."

The Effects of Microwave emitted by Cellular Phones on Ovarian Follicles in Rats.
“The number of pups per delivery was significantly decreased in the exposure group compared to the control group. The data showed that in the pups of the exposed group, the number of follicles was significantly lower than that in the control group. The decreased number of follicles in pups exposed to mobile phone microwaves suggest that intrauterine exposure has toxic effects on ovaries.“

Effects of 2.45 GHz microwaves on meiotic chromosomes of male CBA/CAY mice.
"The findings are interpreted to indicate interference with normal spermatogenesis during the exposure period."

Effects of microwave at 2.45 GHz radiations on reproductive system of male rats.
"Chronic exposure to these radiations produced formation of apoptotic cells in testis. In addition, a significant decrease in the levels of GPx, and SOD activities as well as an increase in CAT activity was observed in the exposed group. These results indicate that a low level exposure of microwave radiations exerts a negative impact on male reproductive system function."

Biological Effects of Mobile Phone Electromagnetic Field on Chick Embryo (risk assessment using the mortality rate)
"Chicken embryos were exposed to EMF from GSM mobile phone during the embryonic development (21 days). As a result the 
embryo mortality rate in the incubation period increased to 75% (versus 16% in control group)."http://www.ncbi.nlm.nih.gov/pubmed/14658287
