How long does it take for a chlamydia infection to show up?
It usually takes one to three weeks for men to show symptoms of infection. It may not be possible to detect chlamydia if a test is performed less than 72 hours after exposure. Without treatment with an appropriate antibiotic it is unlikely that the body will clear itself of the infection. It is therefore possible to test positive for chlamydia from an exposure years earlier. As a consequence it is a leading cause of pelvic inflammatory disease and associated fertility difficulties.
