Abstract
Minors are increasingly reaching countries far from their homes as migrants, and their ages are often unknown. In Europe, up to 1500 people per country annually have medical examinations and procedures to estimate their chronological age.1 These procedures can cause considerable harm to individuals, particularly if performed without appropriate safeguards. Inappropriate age estimation may deter minors from applying for asylum in specific countries, and doctors may find themselves exploited in the service of migration policy. During missions, military doctors face demands to estimate the age of child soldiers destined for potentially unlawful detention or interrogation. Doctors therefore need to be aware of the limitations of medically estimating age and the associated ethical problems.
