Transsexuals Maiamar Abrodos, right, and Maria Laura Aleman pose for a picture as they arrive at the civil registry to begin the legal process to change their gender, in Buenos Aires, Argentina, Monday, June 4, 2012. Argentina's gender identity law that won congressional approval with a 55-0 Senate vote earlier this month went into effect Monday. Transgender rights activists say Argentina now leads the world by granting people the right to change their legal and physical gender identity simply because they want to, without having to undergo judicial, psychiatric and medical procedures beforehand.
