Chlamydia is caused by bacteria that infect the mucous membrane (lining) of the genitals. This STI is common among young women. And it is women who don't usually notice that they have a chlamydial infection. About 60% of all infected women have no obvious symptoms. If the infection isn’t treated at an early stage, there can be complications. Chlamydia can cause an infection in the urethra, anus and cervix. It can also spread to the fallopian tubes and this can lead to infertility. An untreated chlamydia infection in men can cause a swelling in the testicles.


In women:

  • Pain in the lower or upper right abdomen
  • Pain when passing urine
  • Pain during sex
  • Bleeding between periods
  • More or a different kind of discharge

In men:

  • Pain when passing urine
  • Watery discharge from the penis
  • Pain in the scrotum

Chlamydia is easy to treat if diagnosed in time.

Safe Sex

Use a condom for vaginal, anal and oral sex. Use a dental dam for licking the vagina or anus (rimming). Take care when sharing sex toys and avoid any unprotected genital contact (even using your hands).
