Gender Affirmation Surgery, Transmasculine.

Transmasculine genital gender affirmation surgery (GAS) is evolving rapidly due to social and surgical advances over recent decades.

Disappointingly, most publications have thus far failed to address standardization, classification systems, and prospective trials to help guide shared decision making. This narrative review highlights contemporary techniques, controversies, and innovations while addressing gaps in the literature and future directions for research.
