We hope you will take a look at this research and consider the implications to our children's health and future.  Our daughters are born with one set of eggs at birth. If their ovaries or eggs sustain damage, then the effect is permanent.

The NACST thinks prevention is the best medicine.  We do not want to wait to find out what the health effects of holding iPads on laps will be.  The research below gives us enough early warnings to take precautions now.

  • Ex vivo exposure of human spermatozoa to a wireless internet-connected laptop decreased motility and induced DNA fragmentation by a nonthermal effect.

  • 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).

  • “Radiofrequency electromagnetic waves emitted from cell phones may lead to oxidative stress in human semen.  We speculate that keeping the cell phone in a trouser pocket in talk mode may negatively affect spermatozoa and impair male fertility.”

  • Those suffering from erectile dysfunction carried a switched-on mobile phone 4.4 hours per day on average, compared to just 1.8 hours per day for the men who did not experience impotence.

De Iuliis GN, Newey RJ, King BV, Aitken RJ., Mobile phone radiation induces reactive oxygen species production and DNA damage in human spermatozoa in vitro. PLoS One. 2009 Jul 31;4(7)
  • In step with increasing SAR, motility and vitality were significantly reduced after RF-EMR exposure, while the mitochondrial generation of reactive oxygen species and DNA fragmentation were significantly elevated (P<0.001). Furthermore, we also observed highly significant relationships between SAR, the oxidative DNA damage bio-marker, 8-OH-dG, and DNA fragmentation after RF-EMR exposure.  These findings have clear implications for the safety of extensive mobile phone use by males of reproductive age, potentially affecting both their fertility and the health and wellbeing of their offspring.

Shahin et al. 2.45 GHz Microwave Irradiation Adversely Affects Reproductive Function in Male Mouse, Mus musculus by Inducing Oxidative and Nitrosative Stress.Free Radic Res. 2014 Feb 4.
  • Significant decrease in sperm count, sperm viability, decrease in seminiferous tubule diameter, degeneration of seminiferous tubules.  Reduction in testicular 3β HSD activity and plasma testosterone levels and increased expression of testicular i-NOS was observed.  These “adverse reproductive effects suggest that chronic exposure to microwave radiation may lead to infertility via free radical species-mediated pathway.”

  • 30 minutes every 24 hours pregnancy resulted in “decreased number of follicles in pups exposed to mobile phone microwaves suggest that intrauterine exposure has toxic effects on ovaries.” The authors state, “microwaves of mobile phones might decrease the number of follicles in rats by several known and, no doubt, countless unknown mechanisms.”

  • “The ovarian size of the exposed insects is significantly smaller than that of the corresponding sham-exposed insects, due to destruction of egg chambers by the GSM radiation, after DNA damage and consequent cell death induction in the egg chamber” cells of the virgin females as shown in previous experiments on inseminated females.

  • Sperm viability, motility, and total antioxidant capacity in all exposure groups decreased significantly compared to the control group (p<0.05). "These waves can also decrease sperm total antioxidant capacity in rats and result in oxidative stress."

  • This study concludes that RF-EMF exposure had a significant effect on sperm morphometry.  In addition, a significant decrease in sperm binding to the hemizona was observed.  These results could indicate a significant effect of RF-EMF on sperm fertilization potential.

  • Their results indicated that mobile phones may cause endometrial apoptosis and oxidative stress

  • The fertility literature is inconclusive, but increasingly points towards significant time- and dose-dependent deleterious effects from cellphone exposure on sperm.  Genotoxic effects have been demonstrated from "non-thermal‟ exposures, but not consistently.  There is sufficient evidence and expert opinion to warrant an enforced school policy removing cellphones from students during the day.

At this time significant research has shown that wireless radiation damages fertility and could even damage even our children's future reproductive capabilities.  Exposure to wireless radiation is linked to :

  • Decreased sperm count, sperm motility and vitality
  • Sperm DNA damage 
  • Ovarian changes
  • Decreased fertility
  • Erectile dysfunction


  • Have your children use technology with the Wifi OFF.
  • Do not store your cell phone in your pants pocket.
  • Prefer wired connections.
  • Reduce the wireless radiation in your home.
  • Reduce your time spent in WiFi hot spots.
  • Take action to reduce your child's exposure at school and home.
