What is Chlamydia?

Chlamydia is the most common bacterial sexually transmitted infection (STI) in the UK and can cause infertility in both men and women.

Often called the silent epidemic, chlamydia can stay undetected for months and years, with up to 70 per cent of people not experiencing any symptoms of infection.

The only way of checking if you have a chlamydia infection is to take a test. However, research by Clamelle found that although 94 per cent of people are aware of chlamydia and its implications for infertility, only one third of people have been tested.

Chlamydia could be passed on to you by a sexual partner without you knowing and then stay hidden for years.
