Working on a laptop wirelessly may hamper a man's chances of fatherhood. In a study, sperm placed under a laptop connected to the internet through wi-fi suffered more damage than that kept at the same temperature but away from the wireless signal. The finding is important because previous worries about laptops causing infertility have focused on the heat generated by the machines. In the latest study, researchers took sperm from 29 men aged 26 to 45 and placed them either under a wi-fi connected laptop or away from the computer. The laptop then uploaded and downloaded information from the internet for four hours. At the end of the experiment, 25% of the sperm under the laptop had stopped moving and 9% showed DNA damage. By comparison, just 14% of samples kept away from the wi-fi stopped moving. And just 3% suffered DNA damage, the journal Fertility and Sterility reports. The wireless connection creates electromagnetic radiation that damages semen, the scientists, from the United States and Argentina, believe.
使用接入無(wú)線網(wǎng)絡(luò)的筆記本電腦可能會(huì)造成男性不育。 在一項(xiàng)研究中,放置在開通無(wú)線網(wǎng)絡(luò)的筆記本下面的精子比放在同一溫度下但遠(yuǎn)離無(wú)線信號(hào)處的精子受損程度更深。 這項(xiàng)發(fā)現(xiàn)很重要,因?yàn)橹瓣P(guān)于筆記本電腦引起不育的矛頭都指向電腦產(chǎn)生的熱量。 在這項(xiàng)最新研究中,研究者收集了29名年齡在26到45歲之間的男子的精液,并將其分別放在連接無(wú)線網(wǎng)絡(luò)的筆記本電腦下面和遠(yuǎn)離電腦的地方。 接著,筆記本電腦連續(xù)四個(gè)小時(shí)在網(wǎng)上上傳下載信息。 實(shí)驗(yàn)結(jié)束時(shí),放在筆記本電腦下面的精子中,有25%不再游動(dòng),另有9%DNA受損。 而遠(yuǎn)離電腦的精子中,只有14%不再游動(dòng),并且僅有3%出現(xiàn)DNA損傷。這項(xiàng)研究報(bào)告發(fā)表在《生育與不育》期刊上。 來(lái)自美國(guó)和阿根廷的科學(xué)家認(rèn)為,無(wú)線網(wǎng)絡(luò)產(chǎn)生的電磁輻射會(huì)損害男性精子。
