Jan Vinzenz Krause of the Institute for Condom Consultancy measures a prototype of a spray-on condom, in Singen December 5, 2006. Krause’s team are hoping to produce the perfect condom for men that’s suited to every size of penis. They are developing a type of spray can into which the man inserts his penis first. At the push of a button it is then coated in a rubber condom. Krause said the plan is to make the product ready for use in about five seconds. He said it would function more effectively as a contraceptive because it would fit better and not slip. He had hit upon the idea when considering the difficulties some people faced using condoms, and drew inspiration from spray-on plasters now used in medicine. REUTERS/Miro Kuzmanovic (GERMANY)
