(The Telegraph) -- Sex toy injuries have doubled since 2007, with a large increase in 2012 and 2013, after the release of the Fifty Shades of Grey books.
The figures are estimates from the National Electronic Injury Surveillance System, which has tracked casualty admissions since 1991, the Washington Post reported.
The injuries relating to "massage devices and vibrators" were initially low but began to rise steeply from 2005, when around 1500 people across the US received treatment for sex injuries.
Middle aged men were most likely to get such injuries. Male patients accounted for 58 per cent, with the median age in that group being 44 years old. The median aged for women was younger, at 30 years old.
