If the person has a vagina but also testes who gets to decide they are male and not female?
If Khelif has 46XY 5-ARD, which is what is widely suspected, then he doesn't have a vagina. It's the prescence of testes that makes a person like that male. The defininition of sex is which of the two types of gametes the person produces, or would produce if everythinig was working properly. Presence of testes mean male.
Almost all people with DSDs are either male or female, because they have either testes or ovaries, but often don't have clearly defined external genitalia to match.
when it comes to sports, the authorities need to come up with some clear rules, and that’s always going to be hugely contentious and complex
If the athlete has male testes, and produces and uses testoerone in the normal male range - and especially if they went through puberty with testosterone having the normal male effect on their bodies - then they should not be eligible for the female category.
It's possible to determine this nowadays. If the simple chromosome test shows they are not the sex they appear to be, then further investigation can find out what DSD they have, and whether it gives them male advantage in sport.
The DSD conditions might be complex, but it's straightforward to find out whether the athelte has male advantage.
some intersex people have both a vagina and a uterus, they can procreate, have a baby, but also have a Y chromosome.
In that case they are female.
no one knows what category the boxers fall into
No, but the reason that competitors and their coaches started to complain to the IBA over the last few years about these two boxers, was because they appeared to have male characteristics, ie were far stronger than the range of strength in female boxers.
That's why there is widespread suspicion that they have a DSD that means they are male and have male advantage.
so no one should be saying they are a man and deluded,
I said that Semenya was deluded, because we know he is male and yet he continues to believe he's female. I said that it might be the same for Khelif.
The fact that the IOC refuses to test the boxers is what is causing this fuss. Proper tests would establish once and for all whether they are eligible for the female category or not. If they are not, the authorities don't need to reveal the reason for their ineligibility, simply to say, as the IBA did, that they are ineligible.
The fact that neither boxer went through with an appeal to the CAS over the IBA test results in 2023 stongly suggests they knew they wouldn't win their case.
