Transsexual Sandra Gonzalez holds her passport as she waits for documentation in the legal process to change gender, outside the civil registry, 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.
