RESUMEN
OBJECTIVE: Describe and analyze the mental health service and medical needs of a group of transgender men from the point when they changed their gender identity to male. MATERIAL AND METHOD: Transgender men volunteers who attended a specialized care center in Mexico City answered a qualitative semi-structured interview to explore their needs as well as the adversities they unnecessarily face due to the lack of information and care for their condition. Interviews were audio-recorded and transcribed for thematic analysis. RESULTS: Respondents began to develop their transgender identity in childhood; however, during that time, almost none of them had any helpful contact with a health professional. Those who did receive some form of care received mistreatment rather than positive feedback. It was not until adulthood that they obtained facts about a specialized care center. CONCLUSION: It is necessary for health professionals to have information about sexual diversity and be trained to meet the needs of transgender children, in order to have information on places and professionals who accompany them and advise on available treatments such as hormone blockers or treatments. The study includes a small but important sample. However, the currently hostile, discriminatory environment, significantly exposes transgender people to developing mental health problems.
