The short answer
Yes, if it goes untreated. Chlamydia can move from the cervix into the uterus and fallopian tubes, causing pelvic inflammatory disease. Scarring of the tubes can lead to infertility or ectopic pregnancy. Early testing and treatment with antibiotics prevents this, which is why screening matters even without symptoms.
Chlamydia is often silent. Over time, untreated infection can inflame the tubes (PID). Tubal damage blocks the path between egg and sperm, a recognized cause of infertility.

If you have had chlamydia before and are struggling to conceive, tell your doctor; tubal assessment may be suggested.
