The Fallopian tube is where the sperm meets the egg and fertilisation occurs. Because the symptoms of PID are vague or non-existent, most women don't realise anything is wrong, and discover the problem only when they try to get pregnant. So any woman who thinks she might be at risk of chlamydia definitely needs a check-up, because it can be treated very easily with the correct antibiotics. However, half of the men affected don't notice anything. So you can't be sure that you don't have it.
Some women notice a slightly increased discharge, or slight bleeding between periods or after sex.
Chlamydia infection is very common Chlamydia is caused by infection with chlamydia bacteria. Many people have never heard of it, but it is the most common sexually transmitted infection in Britain. There must be hundreds of thousands of people with chlamydia who are unaware they have it, and therefore don't go to a clinic. When doctors in Portsmouth tested urine samples from sexually active women under the age of 25 who were visiting their GP for any reason, they found about 1 in 10 had chlamydia. No one is happy at the thought of visiting a genito-urinary clinic.
