Oh.
It does need to be looked into.
Intersex athletes is an issue that has a 70 years or more history. Things change as we know more. See José Martínez-Patiño as an example of women caught up in previous testing regimes.
It used to be that it was a visual test. Show us your vagina - congrats, you are a woman. This was up until the 1960s. Then we had chromosone-based gender testing.Officials collected mouth scrapings and ran a simple test for the presence of two X chromosomes. The method proved to be unreliable, since it's possible for a biological male to have an extra X chromosome (XXY) or a female to only have one X chromosome. By 1992 there were tests for genes related to embryo development - SRY. If you had SRY gene material you werent a woman. That test didn't work, either. Having the SRY gene material, or even a Y chromosome, doesn't always make you a man. Some people born with a Y chromosome develop all the physical characteristics of a woman except internal female sex organs.This can result from a defect in one of the genes that allows the body to process testosterone. Someone with this condition (known as "androgen insensitivity syndrome") might be XY, and she might develop testes. But she'll end up a woman, because her body never responds to the testosterone she's producing. Other signs of AIS include hairless genitalia and the absence of menstruation.
The new rules (prior to the current suspension of them I think) had, when and if, Semenya failed the initial hormone screen, she’d be examined in more detail to see if her testosterone was “functional” enough to give her an advantage. How would the doctors figure out if her testosterone was functional? They’d check how much of it was bound to her receptors, screen her for known mutations in those same receptors, weigh the hoarseness of her voice, rate the development of her pubic hair and breasts, evaluate her muscles, size her labia, palpate her vagina, and measure her anogenital distance. In other words, they’d try to calculate the degree to which she’d been virilized—or one might say, made “manly”—by her intersex condition.
It is, very invasively, being looked into.
