This article focuses on the provision of gender-affirming care and preventive care for transfeminine individuals-those assigned male at birth who identify as female or on the feminine spectrum. To meet the learning needs of health care providers less familiar with gender-affirming care, this article begins with an overview of gender identity concepts. Initiation and management of feminizing gender-affirming hormone therapy is then covered in detail, including common gender-affirming medications and their adverse effects, diagnostic criteria, psychosocial evaluation, initial physical examination and laboratory work, and recommendations for follow-up visits and laboratory monitoring. Lastly, the article briefly reviews health care of transfeminine individuals before and after surgical gender-affirming interventions and details best practices for transfeminine preventive care.
