My partner told me that he/she once had chlamydia but had it treated. How could that affect me?

Provided both partners have treatment at the same time, once treated, chlamydia is completely gone. If your partner and their partner at the time were not treated together and continued having sex, your partner may have been re-infected. If this was the case, you may be at risk if you are having sex without using a condom.

It is possible that the infection caused damage that could result in your partner becoming  infertile. It really depends on how long your partner had it before treatment.

Head along to your local Family Planning Clinic, Sexual Health Service, Youth Health Centre or your own doctor for a sexual health check-up. You can arrange it so that you are both allowed to see each other’s results which is a good idea to remove any doubt. If you have had recent partners, you might want to wait 3-6 months and return for a second check-up as some STIs can take a while to show up in a test.
