I’ve read it about ten times and it’s just a hot mess of platitudes (not always bad), overlapping concepts, absent definitions and inconsistent ‘rules’.

Devil’s advocate: I could have written a better framework document for them.
Pretty sure this doesn’t preclude eligibility criteria by sex 😂
You can test trans athletes for ‘disproportionate’ advantage but it can’t be a test initiated because of their sex or gender identity 😂
Another here: so ‘cis’ males can’t be systematically excluded? 🙄
If ‘unfair’ is defined as ‘an advantage gained by altering one’s body’, that’s transmen on testosterone out then. <no laughing face>
And if ‘disproportionate’ is defined as ‘outside reasonable advantage in elite comp (not verbatim)’, why are they congratulating Hubbard, whose winning margins in age-matched elite comp were well beyond typical winning margins? 🙄

Richard Budgett, medical director of the IOC, is saying here that sports performance is not proportional to natural (“endogenous”) testosterone level.

What do we know?
1. Males are, as a class, better athletes than females.
2. Males have, as a class, higher testosterone (T) levels than females.
3. T has well-researched effects on sports relevant physiology.
4. The effects of T on sports relevant physiology happens during male puberty.
So what on earth can he possibly mean when he says that performance is not proportional to natural T level? More, that is it *obviously* not and anyway who thinks otherwise must be stupid or something.

With Cathy's permission, I have converted the stats from this paper into graphic form.

Read on.
First, Cathy reported the numbers and % split of UK males and females playing selected sports. Male participation is higher than female participation.
Then, Cathy used population estimates to predict the numbers of male and female athletes who would be eligible, under a selfID model, for the opposite sex category. Cathy calculated these trans athletes as % of opposite sex category.

“From time to time, politicians and other rulers-of-men like to categorize the natural world not according to biology, but rather for convenience or monetary gain.”
“So in the 17th century, the Bishop of Quebec approached his superiors in the Church and asked whether his flock would be permitted to eat beaver meat on Fridays during Lent, despite the fact that meat-eating was forbidden.”
“The Church, by the way, also classified another semi-aquatic rodent, the capybara, as a fish for dietary purposes. The critter, the largest rodent in the world, is commonly eaten during Lent in Venezuela.”

@MargaretAtwood Why?

Microchimerism is common during/after pregnancy. It is the phenomenon that permits us to diagnose fetal sex and chromosome disorders from a maternal blood sample.
@MargaretAtwood If a female has carried a male child, those fetal cells she carries often incorporates will be XY.

Fetal microchimerism has outcomes for maternal health. Most wondrous is the role of fetal cells in tissue repair when pregnant Mum suffers tissue damage.
@MargaretAtwood Tracking fluorescent rat fetal cells when pregnant rat Mum has a cardiac arrest shows those fetal cells trafficking to the damaged tissue to contribute to repair.

Amazing stuff.

“If you don’t want me talking about sexual abuse just fire me,” said Hogshead-Makar.

@Hogshead3Au
Unbelievable details in this story.

Nancy’s continued relationship with @WomensSportsFdn dependent on no discussion, writing or advocacy regarding sexual abuse, harassment or allegations, as either a private citizen, on behalf of WSF or on behalf of anyone else.
Rather than submit all documents, erase all hard drives and surrender copyright for 30 years of legal work and advocacy for WSF, Nancy told them to stuff their severance pay and took everything. 👏

I’ve explained, as far as is possible, this paper many times. Here’s another shot.

ncbi.nlm.nih.gov/pmc/articles/P…
1. A 17 year old woman with no menstruation is examined and found to have no palatable gonads (no testes/ovaries) and a small uterus. Her karyotype was identified as XY.

This looks like Swyer Syndrome.
2. Examination of this woman’s family history revealed, on her mother’s side, multiple family members with infertility, ambiguous genitalia etc.

Suggests she inherited her disorder from Mum, which is a bit odd, because her Mum is clearly fertile and apparently typical female.
