Is it true that chlamydia sometimes can cause infertility or etopic?

Yes: Chlamydia that isn't treated promptly and gets to the tubes can cause scarring in the tubes. This scarring can lead to difficulty in getting pregnant as well as ectopic pregnancy (a pregnancy that grows outside the uterus like in a tube). Your best option is to get tested if you have a new partner or symptoms and treated right away.

Yes, but not always: Not all chlamydia infections cause problems. Women under 26 should be tested yearly. It can cause scar tissue (adhesions) around the fallopian tubes or ovaries which can affect the tubes' function causing ectopic pregnancy, or block the tubes or stop the egg getting to the tube causing infertility. Chlamydia can lead to pelvic inflammatory disease which can damage the ovaries and lower egg supply.
