A gynecologist cannot tell if a person has chlamydia just by examining them but will collect a cell sample for laboratory testing.
If a person has had untreated chlamydia for a while, it can spread to the upper reproductive tract, the uterus, and the fallopian tubes. This can lead to pelvic inflammatory disease (PID).
PID can cause pelvic pain, ectopic pregnancy, and infertility.
