Recent research indicates the use of laptops equipped with wifi can threaten male fertility. Preliminary research, published the journal Fertility and Sterility states, wifi connection on the laptop could potentially threaten the quality of sperm.
The results of experiments in the laboratory by exposing the wi-fi signal near the sperm showed motility of sperm cells decreased. In addition, the sperm is also changing the genetic code.
Although wi-fi effects were apparent in these experiments, the researchers assert, the same effect will not necessarily happen in real life. Therefore, these findings need to be followed up by subsequent studies to ascertain the effects of the use of wi-fi laptop to sperm.
Not the effect of hot temperaturesExperts from Argentina and the United States conducted the study by testing 29 samples of sperm from healthy men. Each sample was divided into two containers, and one was kept for 4 hours at the nearby laptops connected to wireless internet. Samples were kept in a container in the same duration in places that do not have laptops.
The researchers suspect, adverse effects on sperm arising in this trial is not related to the heat caused by the laptop. Despite the hot temperatures are since long known to interfere with sperm quality.
Health Protection Agency (HPA) UK argues, those who use wi-fi connection or are near a wi-fi devices can indeed be exposed to radio signals. Most of the energy emitted from the signal will be absorbed by the body. But exposure to signals from wi-fi so far believed to be safe because its strength is very low.
Until now, the HPA said, have not found scientific evidence that states that exposure to radio signals from wi-fi can damage the health of the population in general.
Andrology and fertility of the University of Sheffield, Dr Allan Pacey, stated, this research needs to be further developed to ensure the effects of exposure to wi-fi signal.
"This research has been done well, but we need to be aware of what can affect the fertility of men who regularly assume the laptop wi-fi," he said.
Sperm that have diejakulasi, continued Pacey, is sensitive to many factors. Because, when it is outside the body, the sperm no longer have the protection of cells, tissues, and other body fluids that are stored before ejaculation.
"Therefore, we can not conclude from this study that men who use a laptop wi-fi on pangkuanya for approximately four hours can be damaged or become less fertile sperm. We need a larger epidemiological studies to confirm it and so far it has not ever done, "said Pacey.
