OK, but then why did the IAAF let her keep competing as a woman for several years after they tested her in 2009?

“The IAAF did not release the results of the tests, but media outlets began reporting on alleged leaks, fueling even more speculation about Semenya’s private medical information. Australia’s Daily Telegraph newspaper claimed that Semenya was a “hermaphrodite,” a term that the Intersex Society of North America deems stigmatizing and misleading. A BBC correspondent said in 2009 that Semenya had “testosterone levels that are three times higher than those normally expected in a female” and that “it’s likely that she has some hermaphroditic or intersex condition.”

“No matter what her personal medical history is, her story illustrates the way people, especially people of color, can be scrutinized when they seem to fall outside gender norms.”
