Chlamydia is the most common sexually transmitted infection (STI) in the UK. 1 in 10 young people who are sexually active have Chlamydia and they don't know it! Chlamydia is easy to transmit between sexual partners. Both males and females very often have no symptoms. However, if not treated, Chlamydia can cause pelvic pain, infertility and blocked fallopian tubes in females; in males, testicular problems and reduced fertility can occur.
