[Question #3681] chlamydia

35 months ago
I was diagnosed chlamydia in April 18. My partner and I have long-distance relationship. Last time we had sex was in January. After the doctor told me that I have chlamydia, I asked my boyfriend to test. However, his result is negative. I don't have any other sexual partner and did not have sex with any other people. I would like to know the possibles reasons for this situation. What are the possible reasons? Thank you very much!

Welcome to the forum. Thanks for your question.

This is a very common situation. Among all persons with chlamydia, the partner who likely infected them often tests negative. There are several possible explanations. Chlamydia is cleared by the immune system over time; in men this typically is just a few weeks or a couple of months. So your partner might have been infected but the problem is now gone. Second, the test could be wrong. The best chlamydia tests miss roughly 10% of infections. We probably should also consider the possibility your partner had sex with someone else, suspected something was wrong (or had a positive chlamydia test), took an antibiotic and was cured, but isn't being honest with you. (That's not an accusation. But it's a fact of life that some persons are not entirely truthful about such things. And surely you have some understanding of the sexual implications of long-distance relationships. You're in a much better situation than I am to judge this possibility:  you know him and I don't.)

The most important thing is that your partner needs treatment for chlamydia despite is negative test result; and the two of you should not be having sex until both have been treated.

I hope this information is helpful. Let me know if anything isn't clear.

Thank you very much for your quick response. Just want to confirm. If he take the treatment without being positive, shall the medicine have some side effect on him?

The antibiotics used for chlamydia are very safe and usually have no side effects. And side effects are not more common if someone doesn't have an infection.
