Size matters when it comes to safe sex.

A southern Swedish health clinic is offering services to men to measure their penis in order to fit them with the correct condom size.

Specially designed tape will measure penises in diameter rather than in length and the clinic hopes the unique opportunity will help boost the number of young men to visit youth clinics.

Emelie Svensson, a nurse at the clinic, told radio station P4 Blekinge: "When you get guys to visit you can move on to mental health, so we want to get them here one way or another."

Condom use numbers in Sweden is declining, reported The Local, despite the country having very high numbers of sexually transmitted disease cases.

Sweden was named the STD capital of Europe in 2013, according to studies by Health Express.

In 2015, there was a 26 per cent increase of gonorrhoea cases and a 35 per cent increase in syphilis cases, according to Sweden's Public Health Agency.

The health clinic hopes that the higher spread use of condoms will encourage safe sex practices in young Swedish men.
