WiFi devices affect sperm, suggests study

7 May 2019
Appeared in BioNews 997

A small study by researchers in Japan has indicated that exposure to WiFi may have detrimental effects on sperm function.

The study assessed the effect of electromagnetic (EM) waves from WiFi devices on human sperm. It found that longer periods of direct exposure to a portable WiFi router decreased the motility rate and increased the death rate of sperm from human samples.

The researchers also found that using a small WiFi shield to block EM waves improved the outcome for the sperm. The work was presented at the Asia Pacific Initiative on Reproduction (ASPIRE) conference in Hong Kong.

'Recently, the decrease in fecundity in developed countries has been a matter of great concern,' said Kumiko Nakata at the Yamashita Shonan Yume Research Centre in Fujisawa, Japan, who led the study. 'EM waves are said to be safe, but the shower of them caused by WiFi devices may be a contributing factor to the declining fertility trend.'

She added: 'Our study has shown that over a relatively short time, a WiFi shield can offer some protection from the harmful effects of the EM waves.'

The sperm samples analysed were taken from 51 men seeking fertility treatment, such as IVF or artificial insemination, at the clinic.

Samples were tested under different conditions; no exposure to EM, shield-protected, and full exposure.

The exposed samples were placed near a pocket WiFi router – similar to the way a mobile phone might be carried in a man's trouser pocket. After two hours, sperm from all groups had decreased health and motility, but the most substantial effect was seen in the sperm with full exposure to EM waves. The difference in sperm health between groups was seen even more clearly after 24 hours of exposure.

'Judging by the results of the current study, it is fair to assume that the longer the exposure is, there is a higher risk for potential negative effects,' Nakata told newsGP. 'And what I mean by longer exposure is not only a few days, weeks or months – we are talking about years. So looking at billions of people over the next few decades, the impact could be huge when it comes to fertility rates.'

The rise in WiFi-based technology in recent years has prompted concerns over its effects on human health. The possible links between exposure to WiFi connections and sperm quality has been previously investigated with laptops (see BioNews 636), and mobile phones in trouser pockets (see BioNews 758).

Yes, the EMF spectrum has its effect on all forms  of life that is well acknowledged.
The secret is it is all about dosage. Put your hand closer to any light bulb for the thermal effects.Yes, the EMF spectrum has its effect on all forms  of life that is well acknowledged.
The secret is it is all about dosage. Put your hand closer to any light bulb for the thermal effects.
The thermal effect is caused by the vibrational  frequency of the emitting source commonly from 50HZ into the Ghz range.
The vibration intensity causes molecules, cells and tissue to rub against each other causing friction, breaks bonds and causes other damage.
The other effect is cellular metabolic neurological interference due to the induction of current triggering normal biochemical process at given J values.
As we all know the body produces its own voltages and has naturally flowing currents and most of what we experience inside our bodies is lower than that of outside exposure.
Yes, the electric chair is an exception. This is not rocket  science. There has been a tremendous amount of controlled advanced research testing that is ongoing  but you need to find it as it is available.
Unfortunately much is behind the dollar door that you must pay for. Surprisingly when you do see these studies they say exactly what is said here.  Being part of one of the world's largest medical technical publication journal I have been part of the peer review process  have seen them and many others that are not generally available due the fact they are internal to science.
Yes, there is a glass ceiling to their availability  limited to researchers that even academia has no privy.
In closing with many decades of working with over 1,000 patients  having concern about exposure to the electron at every frequency   conducting exposure studies for government , state, and private   having seen it all. There are no mysteries at any level regarding exposure. Get off the websites that sell fear, filters, gadgets and come to "test" by  silly meter readers.
