Chlamydia

Symptoms might show within one to three weeks of infection, but around half of those infected have no symptoms.

Chlamydia in the penis can cause a whiteish discharge and a burning feeling, especially when urinating.

Chlamydia in the throat is usually symptom-free.

It usually causes no symptoms in the rectum but might cause discomfort and discharge.

Among men, chlamydia is spread during oral or anal sex without condoms. It can also spread on fingers when you touch an infected part of the body then touch other parts of your or another man's body.

Using a condom cuts the risk.

If you have HIV, having untreated chlamydia makes it more likely that you’ll pass on HIV during unprotected sex.

There’s a urine test for Chlamydia, or a sample is taken from the infected part of your body using a swab (small cotton bud). Swabs taken from the rectum and throat don’t hurt - a swab taken from the inside tip of your penis is uncomfortable for a second or two.

Chlamydia is treated with antibiotics. Don’t have sex until treatment has finished or you could pass on the infection. People you’ve had sex with also need to get checked - a clinic can contact them if you don’t want to. Untreated chlamydia sometimes causes serious problems.

Most people get tested and treated for infections like chlamydia at sexual health (or ‘GUM’) clinics. It is free and confidential - no one else, including your GP will be told about your visit. Some GP surgeries also test for and treat these infections.

The more people you have sex with, especially unprotected sex, the more chance you have of getting infections like chlamydia. You can have them without knowing, so regular check-ups are a good idea, especially if you are starting a new relationship and/or you want to stop using condoms with your partner.
