A recent study of 29 healthy sperm donors found the effects of Wi-Fi on the samples unfavorable. Donor sperm samples exposed during a short time period to a wireless laptop showed a marked decrease in sperm motility and an increase in sperm deterioration.
This study was done to evaluate the effects of laptop computers connected to area networks wirelessly on the human spermatozoa. It involved 29 healthy Argentinian donors who had motile, virile sperm samples. The semen from the subjects was collected and divided into two groups, one group was the experimental exposed sperm, and the other group was the unexposed sperm.
The results showed that this sperm that was exposed to the wireless internet-connected laptop (Wi-Fi) showed a significant drop in the progressive sperm motility and an increase in the sperm collapse. Levels of dead sperm were similar for both groups, however. The unexposed sperm was incubated and not exposed to the laptop.

The conclusions were that exposure of human sperm to a wireless laptop will decrease the motility and induce DNA fragmentation. The researchers further speculate that keeping the laptop connected on the lap near the testes may result in decreased fertility of the male or infertility. Further studies were recommended to be absolutely conclusive regarding this issue, however.

Once the healthy sperm were exposed to the connected laptop, a quarter of them were no longer swimming around, compared to just 14 percent of the control, unexposed sample. Around 9 percent of the sperm showed damage to the DNA, three times more than the other sample. The reason for this was said to be the electromagnetic radiation generated during the wireless communication, according to the lead researcher of Nascentis Medicina Reproductiva in Argentina.
 
The researchers believe that this suggests that the use of laptops could decrease the human sperm quality and put the person at risk for infertility. Other research found that radiation from cell phones causes sperm to be sluggish and feeble, too. Heat is said to contribute to this problem, too, as heat lowers levels of sperm. Between the heat and the radiation, testicles can be ‘hard-pressed’ and at risk.

The American Urological Association reports that one in six couples in the United States are having difficulty with conception, and around half of the time, the male partner is to blame. Modern technology may be contributing to this issue. A report in the journal Fertility and Sterility found that men who eat a certain diet have better luck getting their partners pregnant during fertility treatment. Apparently, a diet with lots of fruit and grains and not much red meat, coffee, and alcohol is where it’s at.

The critics agree that much more research on these issues is necessary to confirm the questioned data. Overall, the research is telling us to push back from the T-Bone and turn off the laptop for better fertility success.
