Sexually Transmitted Infections (STIs)

STIs are caused by germs - viruses and bacteria - and are transmitted through vaginal, anal or oral sex.

Most STIs can be easily treated but can cause permanent damage if left untreated, including infertility (inability to have children) . Not all STIs have symptoms, or they may take several weeks or months to develop.

If you have had unprotected sex (sex without condoms) it is important to have a sexual health check at one of our services. The services page can help you to search for STI testing and treatment services near you. The clinics are free and confidential.

It's a good idea for you and your boyfriend or girlfriend to get tested for any STIs before you start having sex.

The risk of getting an STI can be reduced by using condoms. Condoms are the only form of contraception to protect you against STIs and unplanned pregnancy. Read more about condoms.

If you get an STI, you should always tell your partner/s so they can be protected and tested.
