WPATH: World Professional Association for Transgender Health
Persistent, well documented gender dysphoria.
Capacity to make a fully informed decision and to consent for treatment.
Age of majority in a given country.
If significant medical or mental health concerns are present, they must be well controlled.
12 continuous months of hormone therapy as appropriate to the patient’s gender goals (unless the patient has a medical contraindication or is otherwise unable or unwilling to take hormones).
12 continuous months of living in a gender role that is congruent with their gender identity.
Although not an explicit criterion, it is recommended that patients also have regular visits with a mental health or other medical professional. The criterion noted above for some types of genital surgeries – i.e., that patients engage in 12 continuous months of living in a gender role that is congruent with their gender identity – is based on expert clinical consensus that this experience provides ample opportunity for patients to experience and socially adjust in their desired gender role, before undergoing irreversible surgery.
*Above requirements are from the WPATH Standards of Care version 7*
** Please be aware that these above standards of care are not always the same requirements that your insurance plan may follow. They have their own guidelines that patient's must meet prior to approving gender affirming bottom surgery.**
