"Excerpt: As for the trans community, gender reassignment surgery is
only permitted over twenty years of age, and only if one has either
undertaken or been exempted from military service, although the South
Korean Supreme Court (2003) has ruled that transpeople are entitled to
receive alteration of their gender details and names on official
documentation.
