I feel desperately sorry for DSD athletes. Some don't even find out they have the condition until they reach a high level in athletics and they then have to face the whole world knowing their intimate medical information at the same time as struggling to be allowed to continue to compete and do what they love
Bit of a coincidence, though, that Mboma and Masilingi, two phenomenal teenage athletes who both turn out to have this very specific DSD (male chromosomes and internal testes) happen to have the same coach, even though it's being loudly denied that anybody had any prior suspicion at all about their amazing times.
Mboma ran the 400m in June, in Poland, and won with a time of 48.54. The very talented Justyna Święty-Ersetic was soundly beaten into second at 51.91. Like the result in the 200m Olympic race, Mboma's result in that 400m was another under-20 world record, and was the fastest of the year at that point.
The performances of these two still-inexperienced athletes seem to have been truly spectacular for a while and yet nobody ever stopped to think about it. Apparently.
