The youngest age at which gender reassignment surgery (also known as gender confirmation surgery or gender-affirming surgery) can be performed varies depending on various factors, including the laws and regulations of the country or region, the guidelines of medical organizations, and the specific circumstances of the individual.

In many countries, there are legal and ethical considerations in place regarding the age at which gender reassignment surgery can be performed. Generally, surgery for gender reassignment is not performed on minors or individuals who are below the age of consent. Instead, medical interventions for transgender youth often focus on social transitioning, mental health support, and hormone therapy under the guidance of qualified healthcare professionals.

It is crucial for transgender individuals and their families to consult with healthcare professionals who specialize in transgender healthcare, including pediatric endocrinologists and psychologists, to understand the available options, risks, benefits, and appropriate timing for any medical interventions.

The age at which gender reassignment surgery can be performed is a complex and individualized decision that takes into account factors such as physical and emotional development, capacity for informed consent, and the overall well-being of the individual. It is important to work closely with qualified healthcare professionals who can provide appropriate guidance and support throughout the transition process.
