The present study assessed the prevalence of sexually transmitted infections (STIs) in 90 transsexual men (female-to-male transsexual persons) from southern Brazil. A retrospective review of the medical records of all transsexual men who visited an outpatient clinic in Rio Grande do Sul from 1998 to 2017 was performed. Although the sample had a high prevalence of risk factors for contracting STIs, such as drug use, one-third of the participants had never been tested for STIs and, when screened, it was mostly for HIV, but not for syphilis or other STIs. Based only on laboratory-tested transsexual men, the prevalence of syphilis and hepatitis C was 3.4% and 1.6%, respectively, which is higher than the general population. It is clear that health professionals need to broaden their understanding of transsexual men, acknowledging STIs as a possible diagnosis.
