Men who have sex with men


  • This guideline reflects the Australian Sexually Transmitted Infections & HIV Testing Guidelines 2019 for asymptomatic men who have sex with men and is intended for all men who have sex with men, including trans men who have sex with other men.
  • Most STIs in men who have sex with men are asymptomatic. The main barriers to STI control are insufficient frequency of testing and incomplete testing in asymptomatic patients. Testing should be performed at all three sites (swab of oropharynx and anorectum, and first pass urine), and syphilis serology should be performed every time human immunodeficiency virus (HIV) test or HIV treatment monitoring is performed.
  • Pre-exposure prophylaxis (PrEP) effectively prevents HIV infection. All patients who are eligible under the Australian guidelines should be actively offered PrEP.
  • Undetectable equals untransmittable: people who take antiretroviral therapy for HIV daily as prescribed, and who achieve and maintain an undetectable viral load, cannot sexually transmit the virus to an HIV-negative partner.
  • Men who have sex with men may be cis or transgender.
  • A global outbreak of Monkeypox (mpox) virus started in 2022 and mpox infection has almost exclusively been diagnosed among men who have sex with men, transmitted through sexual contact and other similarly close contact. Please visit the Monkeypox (mpox) page for more information.
