The purpose of this move was to detect male imposters, who would have a natural advantage while competing with females.

Ironically these tests did nothing to prevent the males with genotypic variations from participating in the Games.

Genetic basis of gender assignment: By 1980, the Barr body test was considered redundant and the International Olympic Committee (IOC) replaced it with the Polymerase Chain Reaction (PCR) test to detect the SRY gene, linked to the Y chromosome, usually present in males. This was initiated during the
