This is Tupou Neiufu. She is a NZ paralympic swimmer. At two years old, she was injured in a hit a run, and left with a permanent brain injury causing hemiplegia.
She won her first Olympic gold medal at Tokyo 2020.
This is Lisa Adams. She is a NZ paralympic shotputter. She has left hemiplegia.
In 2020, she won her first Olympic gold medal and, in separate competition, set the world record for her event.
This is Sophie Pascoe. She is a NZ paralympic swimmer. At 2 yrs old, she suffered severe leg injuries, resulting in left amputation below the knee, in an accident.
She did not win her first gold medal at Tokyo 2020.
She joined an elite club of 40 athletes with 10 Olympic golds.
This is Anna Grimaldi. She is a NZ paralympic sprinter and longjumper. She was born without a functional right forearm/hand.
She jumped her way to her second Olympic gold at Tokyo 2020.
This is Holly Robinson. She is a NZ paralympic javelin thrower. She was born without a left forearm/hand.
She won her first Olympic gold at Tokyo 2020.

Birds use genetic sex determination, just like humans.
The "make male" gene for humans is called SRY, and it lives on the Y chromosome.
If you have functional SRY and its downstream transcriptional storm, you will make testes and make male.
Birds differ. Their "make male" gene is called DMRT1.
It pretty much works like SRY, in that it's immediate downstream target is the parallel gene in both humans and parrots, and the ensuing transcriptional storm triggers testes development (testes being male, of course).
"This model of estradiol’s role in improving resistance to wound sepsis predicts at least four “sexes” across two treatment groups: females who are in the proestrus phase, females who are in the diestrus phase, females who are postmenopausal, and males."
This is Sarah Richardson, of the Fuentes review.
Four "sexes", three of them female and the other male. JFC.
Apparently-female athletes who test positive for SRY will have a consultation with WA, with a view to medical assessment to better understand any medical conditions (DSDs) they have.
It is this diagnosis that will determine eligibility (or not).
After a primer on sex development, Sinclair tries a gotcha.
Describing Swyer Syndrome and CAIS, he argues these athletes would be unfairly excluded.
But WA makes it clear that CAIS is exempt from exclusion. It’s in both the policy and the press release. I doubt Swyer would be excluded either.
Five years ago, I gave a speech comparing sex denialism to creationism.
At the time, my partner-in-crime, Colin Wright, and I were near-lone academic voices willing to stand up and say “Biology! We have a problem!”

Reflecting, back in 2020, on that state of affairs:
“[That] there are two sexes, male and female is apparently something that biologists do not think needs to be said.
I think they are wrong.”
Since then, biologists with far more authority than an unknown developmental biologist who was trying to work out how nerves navigate over muscles and an unknown evolutionary biologist who was studying what makes insects mad have spoken up.
