All boxers, including Algeria's Imane Khelif, who won Olympic gold last summer amid scrutiny over a disputed failed gender eligibility test conducted by a different body, will be unable to compete without a test which reveals their biological sex.

I'm honestly confused about what you're asserting here. For my daughter, they did a blood test on my wife in order to tell us that we're having a daughter instead of a son. Doesn't that mean that there IS in fact a genetic test that "reveals biological sex"?

So there's a relatively miniscule fraction of people who have unexpected outcomes that you wouldn't expect based on their genetics, e.g due to some unexpected hormonal activity during fetal development.

For almost every birth, the biological concept of sex is a straightforward conclusion from genetics, so, by and large, a genetic test is accurate. But there have been cases that never got genetic tests and from all assessments were biologically female, but find out later they had XY. Maybe because they never hit puberty, or while trying to diagnose infertility, but something drove a deeper look.

FYI, Intersex people (those born with nonbinary sex characteristics such as sexual anatomy, reproductive organs, hormonal patterns and/or chromosomal patterns) are approximately 1.7% of the general population.

By comparison, red hair occurs at similar rates, and accounts for between 1 - 2% of the general population.

When you consider how many people with red hair you may have met in your life, on average, you have also met a similar number of intersex people, whether you knew it at the time or not.

The 1.7% figure is generally considered inaccurate, with most of that 1.7% being anomolous, but not out-right counter to the genotypic sex. LOCAH can cause infertility/reduced menstrual cycles as well as excessive body hair or balding in women, but wouldn't generally be considered phenotypically male. The second biggest one is a male having their urethra open in the wrong spot, which while anomolous, is certainly not going to make someone think they should be considered to be sexed female just because their penis has the hole in the wrong place.

The syndromes more like one would expect, like AIS, amounts to somewhere around 0.02% to 0.05%.

But that's why we don't let people with red hair compete in sports either.

That "relatively miniscule fraction" is over-represented in sports, as the hormonal edge cases of humanity can end up being stronger/faster/bigger than the typical humans.

Possibly true, but it would be good to have a source for that.

But even if true, what genetic factors should and shouldn't count? If someone is clearly female to all observers but happens to have XY genes, how is that different from an XX female who has an abnormally high amount of testosterone but still appears female for all intents and purposes?

I'm basically saying it's a complicated problem that laymen like us without specialized knowledge should consider very carefully and possibly defer to experts' opinions.

Well frankly, there's a whole can of worms to be had about how people should be categorized. A different league for distinct height ranges? Different leagues based on ACTN3? There's a whole bunch of uneven biological factors that competitors had no control over, should gender be the only one so broadly recognized?

Looks like it's time to pull out the chart again...

Source.

The test is for the SRY gene, which may not be active on a Y gene, among other things. There are 2 or 3 points on that chart that are relevant to your question.

I want to second the helpfulness of this. Thank you!

[-] Wrufieotnak@feddit.org 3 points 1 day ago

Thanks! That picture is sure to come in handy at some point.

How old is your daughter?
