Transmasculine persons may experience stigma, which increases the risk of psychological distress. They may need reproductive, perinatal, and sexual health care; however, qualitative studies addressing transgender individuals' experiences are scarce. This study aimed at interpreting and describing the experiences of transmasculine persons in encounters with health care professionals (HCPs) within reproductive, perinatal, and sexual health care. Methods: Nine qualitative semi-structured online interviews were conducted via email with transmasculine persons, and data were analyzed by using Braun and Clarke's thematic analysis. Results: Two themes were identified. The first theme is normalization and confirmation of the gender identity. This theme comprises the knowledge and experience that these transmasculine persons are facing. The verbal approach from the HCPs was important as well as could be addressed with a non-binary approach. The second theme is Respect in an especially exposed situation. This theme shows the great importance of being involved in the care and at the same time being met with openness and empathy. There must be good prospects of being able to preserve dignity. Conclusion: Transmasculine persons are in an exposed position in reproductive, perinatal, and sexual health care. The encounters in health care could be negatively affected if HCPs show inadequate knowledge or express gender stereotypical attitudes. A good encounter is characterized by respect, preserved integrity, involvement in the care, and an open attitude toward gender variations.
