Treatment
Antibiotics will clear up the chlamydia infection.
You should not have sex until 1 week after both you and your partner(s) have finished treatment. This includes oral sex and sex with a condom.
If chlamydia is not treated, you may pass it on to other sexual partners.
In women, untreated chlamydia can spread to the womb and cause a serious condition called pelvic inflammatory disease (PID). This is a major cause of ectopic pregnancy and infertility in women.
In men, untreated infection may spread to the testicles and cause discomfort, which could affect fertility.
How chlamydia is passed on
You can get chlamydia through unprotected vaginal, anal or oral sex (sex without a condom). Other ways of getting chlamydia include:
- sharing sex toys that are not washed or covered with a new condom each time they are used
- infected semen or vaginal fluid getting into your eye
Chlamydia can also pass from a pregnant woman to her baby during childbirth.
Anyone who is sexually active can get chlamydia, and it is most common in people under 30.
You could have had chlamydia for some time without knowing it.
