To save further derailment of the Sandie Peggie tribunal threads with people debating Tandora's statements on the above theme, I've started this thread to point them to instead.

You sound way too emotionally invested in this topic to be conducting research with any kind of objectivity. The STEM academics I work with (many of whom have won prizes for public engagement) do not speak like this.

It is not derogatory or offensive to note that CAIS individuals are technically male, whilst agreeing that in this specific situation it is not unreasonable to treat them as socially female. It is also clear to everyone but yourself that this has fuck all to do with Eddie Izzard insisting he gets to use the womens toilets on days he decides to wear high heels and a short skirt.

It’s entirely unreasonable because it is

a) not true/ nothing to do with science.

b) profoundly harmful to real people who are actually living with this condition.

If you knew any actual women living with CAIS , and you understood anything about their real lives, you would feel emotional too (assuming normal levels of human empathy).

I can't explain anything about that assertion because I don't believe it is true.

Trans woman does not erase or redefine the word woman. The trans pre fix clearly sets them apart from biological women. The existence of a trans woman does not redefine or diminish your womanhood in any way, your womanhood is personal to you, no one can change it, steal it, whatever else you claim trans people are doing to it.

Exactly . This is so obvious.

The self centred-ness of humans knows no bounds sometimes. why do they think the simple existence of another person has anything to do with them?

There is no context where it is appropriate or justified to refer to a CAIS person as male. You can refer to the person as having a male karyotype, which is true. That is the end of any appropriate, scientific, reasonable, necessary application of the term “male” when it comes to women with CAIS.

But you said earlier on the thread that some individuals with CAIS are male.

outofdate · 24/07/2025 08:30

@Tandora At least you’ve learnt how to spell karyotype- that’s a start I guess.

There are absolutely female people with Y chromosomes. One classic example (that people on mumsnet get really angry if you talk about) are women with CAIS. They have a y chromosome but their body is insensitive to androgens so doesn’t masculinise in the typical manner. People with CAIS are almost always assigned female at birth, so they would fit the SC definition of biological female/ woman as well as medically . They tend to have typical looking female genitalia externally, but what is known as a “blind vagina” and they do not have ovaries or a uterus.

'almost assigned female at birth'

What sex are are the others, then?

Yes, to be strictly accurate I should have said-

“There is no context where it is appropriate or justified to refer to a woman with CAIS as male. You can refer to the person as having a male karyotype, which is true. That is the end of any appropriate, scientific, reasonable, necessary application of the term “male” when it comes to women with CAIS.”

This refers to almost all people ever born with CAIS. There are a handful of historical cases where people with CAIS have been assigned male. It’s exceptionally rare.

If no-one can change womanhood, then there's no such thing as transitioning.

I actually took a screenshot as I was so shocked.

I wouldn't worry too much about that individuals opinion of you, they've said similar sensationalist things about me and other posters.

It's not personal, they are clearly very angry and their posts are usually full of made up words like transperbole and half written in caps.

There is also one documented case from 2011 with a person with CAIS assigned female at birth with a male gender identity : https://pubmed.ncbi.nlm.nih.gov/20358272/

This is an excellent description of men who claim to be women.

They have no regard for women only spaces, they want to insert themselves there to validate their self identity. They don’t care if they have a detrimental effect upon the sex class of people for whom the space has been designated; it’s as if women don’t actually exist.

The only existence that matters here is that of men, & the idea they hold that they are (obviously not) women. As you say, a boundless self centredness. At it’s worst you could imagine a woman being forced to share a prison cell with a man? Oh, hang on ….

Edited

Previous posters have explained the biological rationale behind why an individual born with CAIS, from an embryo created with a Y sperm cell, can be described as male, with reference to gonads and hormones. To say this approach is "nothing to do with science" is just wilfully silly. We are not the ones wanting to use feelings as a basis for classification.

If using clear, factual terminology is "profoundly harmful" then something has gone wrong with scientific literacy in this country.

I note that this NHS trust's website explains the condition whilst being careful to only refer to "indivduals" or "someone" with CAIS: https://www.uclh.nhs.uk/patients-and-visitors/patient-information-pages/complete-androgen-insensitivity-syndrome-cais

Complete Androgen Insensitivity Syndrome (CAIS) : University College London Hospitals NHS Foundation Trust

This page goes through the science behind CAIS and the different ways which having CAIS can affect someone.

No. Because they are taking about themselves , who they are, you are talking about who someone else is. See the difference?

Do You understand the difference between a karyotype and a person?

If so, this really shouldn’t be hard for you.

people with CAIS have a male karyotype. True, scientific statement.

people with CAIS are male. Totally inappropriate, unscientific, meaningless statement, informed by ignorance and dogma.

In people without a DSD, male karyotype = male person.

In people with a DSD, their sex is determined according to what DSD they have.

CAIS is a male DSD therefore CAIS = male person, even if they may choose to live as if they were female for more valid reasons than trans women do.

Glad to see you can now spell karyotype correctly though. You have learned something from this thread at least.

NeverOneBiscuit · 24/07/2025 08:48

No. It’s about the fact they’re men claiming to be women. So it’s about who they are - men - and who they’re claiming to be.

It’s about the fact that they have one idea of who they are, you have a different idea of who they are, and you seem to think your opinion on who they are is the most informed and important.

I understand, I just disagree.

Interesting thought experiment: if a couple paid for sex selective IVF requesting a boy, and had a baby with CAIS could they take the clinic to court? I assume the clinic would argue they fertilised a Y sperm with an egg and successfully implanted a male embryo, so not their problem.

It might not be their problem because it was no “error” of their own. It doesn’t logically follow from this that the baby is a boy.

I would gently suggest that it’s not really your place to disagree with the facts/ realities of other people’s personhood.

NeverOneBiscuit · 24/07/2025 08:58

No. I don’t have an idea, or a belief, of who they are, they’re a man - it’s a material reality.
Who they say they are, believe/think they are, is nothing to do with their biological sex.
My opinion of them isn’t what prevents them from using female only spaces & services, the law does that.
