The women's doubles defending champions were Mexicans Paola Longoria and Samantha Salas and they won gold for a third straight time.
In the final, they defeated American Aimee Ruiz, a former World Champion doubles player, and Janel Tisinger in two straight games.
Longoria and Salas beat the Chilean team of Angela Grisar and Carla Muñoz in the semi-finals, which was a rematch of the 2012 final.
In the other semi-final, Ruiz and Tisinger needed to come back after losing the first game against the Ecuador team of Veronica Sotomayor and Maria Paz Muñoz, winning the match in a tie-breaker.
Previously, players were seeded into an elimination round based on how their countries had done at previous World Championships, and then a second team competition was also played.
