Chlamydia is a sexually transmitted infection (STI) that affects all genders. It is currently the most common STI, infecting approximately four million people a year. Chlamydia is a bacterial infection, that is curable with antibiotics. It spreads through sexual fluids via oral, vaginal or anal sex.


  • About 70% of the women and trans men with chlamydia have no symptoms. They may have it for years without being diagnosed.

For women and trans men who do have symptoms, they include an

  • unusual vaginal discharge
  • irregular vaginal bleeding
  • pelvic pain
  • painful urination
  • swollen glands near the groin.

About 10% of men and trans women have no symptoms. In men and trans women who have symptoms, they include a

What Are The Health Problems Associated With Chlamydia?

  • In women and trans men, chlamydia usually begins with an inflammation of the cervix.
  • The long-term health effects of chlamydia remain unclear.
  • The medical profession speculates that chlamydia could be a cause of sterility in women and trans men if the chlamydia infection were to spread into the uterus and tubes, causing a pelvic infection and scarring in the tubes (Pelvic Inflammatory Disease or PID)
  • Many women and trans men that have chlamydia do not get PID and not all people with PID have a chlamydia infection.
  • A woman or trans man can also transmit chlamydia to her/his infant during birth. This can cause pneumonia if it spreads to the infant's lungs or blindness if it infects the eyes.
  • In men and trans women, chlamydia may cause urethritis, which is an inflammation of the urethra referred to as NGU or NSU. If this remains untreated, it may also cause sterility.

How Is Chlamydia Transmitted?

Chlamydia is passed to sexual partners during unprotected vaginal, anal and/or oral intercourse.
