This special issue will focus on Gender Affirmation Surgery (GAS) which is an important topic for transgender health professionals.

Gender dysphoria (GD) is a condition in which a person experiences discrepancy between the sex assigned at birth and the gender they identify with, often leading to extensive personal distress. The treatment may consist of psychotherapy, cross-sex hormone therapy, and different forms of GAS in accordance with the Standards of Care of the World Professional Association of Transgender Health. GAS refers to the whole genital, facial, and body procedures required to create a feminine or masculine appearance.

GAS remains an area of super-specialization and in development. Few surgical refinements have been published within the last few years, and follow-ups of a long-term series of patients proceed slowly. Cooperation among the different centers is the solution to standardize approaches and techniques and achieve a higher level of evidence.

This special issue will focus on the surgical part of the Gender Affirmation procedures as well as their impact on the psychosocial well-being of these patients.

Potential topics include but are not limited to the following:

• Criteria for selective surgical techniques
• Definition of patient reported outcome measures (PROM)
• Evaluation of surgical outcomes
• The impact of GAS on the psychosocial well-being of transgender patients
• Long-term follow-up of GAS
• Innovations
• Future of GAS
