 [ Symptoms ] i have knocked knees – no fix – or do i need surgery [ Disease ] hi this is from a site called clamelle co uk 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 do take a test it will help clear up your problem if you do have it both ways do hope this helps good luck
