Results of a study posted on the Wireless Armour [website](https://wirelessarmour.co.uk/em-radiation-kills-25-of-sperm-after-4-hours/) showed that radiation emitted from WiFi devices, like the smartphone in your pocket or the computer on your lap, killed 1/4 of the sperm sample after just 4 hours of exposure, proving that all your Tinder and OK Cupid activity might seriously damage your fertility. The underwear is made from a fabric called RadiaText, which is a blend of cotton and silver. Because silver is a top conductor of electricity, it creates an “unbroken shield” against the radiation, according to the [website](https://wirelessarmour.co.uk/about/). The blend makes it both soft and strong, and the silver makes the underwear “highly anti-microbial,” ergo more hygienic. Prices range from £24 to £35 (about $37 to $55), but can you really put a price on your crown jewels? ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4003928/underwear-fertility-radiation/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4003928/underwear-fertility-radiation/"},"headline":"This Underwear Can Protect You From Radiation Exposure","datePublished":"2015-08-19T21:06:13.000Z","dateModified":"2026-02-22T10:18:02.878Z","description":"It'll keep your swimmers swimming.","url":"https://time.com/4003928/underwear-fertility-radiation/","keywords":["fertility","Science topic","Tech","Radiation","WiFi","pubdesk"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltbe3916360bc71dd8/69886023196cf4bcc2037a47/180-black-bb.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"TIME Staff","jobTitle":null,"url":"https://time.com/author/time-staff/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltbe3916360bc71dd8/69886023196cf4bcc2037a47/180-black-bb.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"180-Black-BB","caption":"Courtesy Wireless Armour","creditText":"","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/4003928/underwear-fertility-radiation/","name":"This Underwear Can Protect You From Radiation Exposure"}}]}] ```
