Scientists are questioning if using wi-fi on a laptop to roam the internet could harm a man's fertility, after lab work suggested ejaculated sperm were significantly damaged after only four hours of exposure.The benchside tests showed sperm were less able to swim and had changes in the genetic code that they carry.
Experts stress this does not mean the same would occur in a real-life setting and say men should not worry unduly. But they are recommending more studies.
The preliminary research, published in the journal Fertility and Sterility, looked at semen samples from 29 healthy donors. Each donor sample was separated out into two pots. One of these pots was then stored for four hours next to a laptop that was wirelessly connected to the internet. The other was stored under identical conditions, minus the laptop.
The scientists, from Argentina and the US, suspect that the effect seen is unrelated to the heat kicked out by a laptop, although heat can damage sperm.
