Many medical professionals and numerous professional associations have stated that surgical interventions should not be required in order for transsexual individuals to change sex designation on identity documents. However, depending on the legal requirements of many jurisdictions, transsexual and transgender people are often unable to change the listing of their sex in public records unless they can furnish a physician's letter attesting that sex reassignment surgery has been performed. In some jurisdictions legal gender change is prohibited in any circumstances, even after genital or other surgery or treatment.
