Olympic boxing champion Imane Khelif won a gold medal at the Paris Olympics last summer amid international scrutiny on her and Taiwan's Lin Yu-ting, another gold medal winner.

The 26-year-old Algerian welterweight was at the center of Olympic controversy regarding her gender at the Paris Games, beginning when her first-round opponent, Italy’s Angela Carini, quit after 46 seconds. Carini eventually backtracked and apologized for causing the uproar.

World Boxing will introduce mandatory sex testing for all boxers in its competitions, the body said on Friday, adding that Paris Olympics gold medallist Imane Khelif will not be allowed to compete until she undergoes such a test.
