Sociodemographic and behavioural factors associated with testing for HIV and STIs in a US nationwide sample of transgender men who have sex with men.

These findings indicate that a notable percentage of TMSM had never tested for HIV and bacterial and viral STIs, though at rates only somewhat lower than among cisgender MSM despite similar patterns of risk behaviour. Efforts to increase HIV/STI testing among TMSM, especially among those who engage in condomless anal sex, are needed.
