Under this campaign, advertisements will appear on television and radio, in magazines and online from Nov. 20. The campaign features teenagers wearing pants sporting slogans such as 'I've got gonorrhea' and 'I'll give you one', with reference to STIs.

Public Health Minister Caroline Flint, said: "Improving the nation's sexual health is a key government priority and improving access times to sexual health clinics, chlamydia screening and this campaign will all help to drive down the number of cases of STIs."

"The aim of this campaign is to make carrying and using a condom among this age group as familiar as carrying a mobile phone, lipstick or putting on a seat-belt," Flint continued.
