I find Martina's comments odd as the Olympic committee has spent decades researching into gender and sport, and has been through various phases, e.g., genital inspection, chromosome analysis, and more recently hormone analysis. There have been problems at every stage, for example, with chromosome analysis, there are individuals with mosaicism, where different cells in the body have XX or XY chromosomes. They seemed to have settled on hormone analysis, thus requiring intersex women and trans women to reduce testosterone, (which is meant to reduce athletic performance), but there is now a legal block on that. It's extremely complicated. Ironically, one of Martina's coaches was Renee Richards, well known trans tennis player.
