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.

I’m not being facetious here, but I’m still not seeing evidence that variations of biological processes means the reality of trans is anything other than an imaginary concept that trans people and many others fully believe in.

There’s nothing wrong with the term sex, you just have to understand what it means when you use it- which is a complex, system of development with multiple components and lots of variations.

Show me the end result of these variations that result in a person being entirely different to male or female culminating in a completely different gamete capable of successfully reproducing.

Can you do that? Simple question

I disagree, but I think we have established that already.

I didn’t say you can’t talk about them, I said you can’t stop others talking about the realities of sex development

I don't want to! I love the reality of biology and sex development and am constantly banging on about it:

Sex is so complex that millions of uneducated people around the world, and even the simplest animals understand it

baby =m+f
no baby something broken perhaps

m+m
or f+f no baby possible

if you think it’s complex you are overthinking it and adding additional factors to it

strip it back to basics and start agin

They don't have mixed sex attributes. They have ambiguous or incorrect secondary sex characteristics due to their DSD. Their sex is clear. In extreme case like CAIS, it might make more sense for them to live as the incorrect sex. And they certainly have a claim to that, unlike normal XY men who just decide they 'feel' like women.

https://theparadoxinstitute.org/read/sex-development-charts

The case law on biological sex bases it on karyotype, gonads, and genitals (including internal structures), at birth, but not psychology. It doesn't tell us anything about the legal position of anyone for whom these three attributes are not in perfect alignment. I've searched in vain for relevant case law, but wonder if it has just never been a problem needing a view from the courts?

So now that you can see that we do understand the complexitis of sexual development in humans, are we allowed to talk about sex? Or is there something else about sex that you are uniquely positions to m.....explain to us? Eg with one of your research papers?

WarriorN · 23/07/2025 17:37

The thing is that I DO understand that the term sex to mean m and f has associated with it, many variables in terms of how genes are expressed etc.

but that’s still not trans.

what is trans?

WarriorN · 23/07/2025 17:38

Also, why do so many people change their minds? Or imagine them selves differently

Your sex denotes which of the two roles you play, or would or could potentially play in sexual reproduction. That's it.
But this is way too simplistic (and also kind of religious).

Where does this simplistic/ reductive framework leave women with CAIS for example ? They are infertile. Even the very weird “oh but their body intended to or was organised around (again very religious as if there’s some sort of intentionality or grand design) this wouldn’t work for women with CAIS as they have a male karyotype. They would fit the definition of biological female for the purposes of the SC judgement though.

These aren’t just scientific debates, it’s actually really harmful to insist on these dogmatic truths.

Remember this morning though, poster's definitions of sex where falsely twisted to drop off the 'whether those small gametes were produced, ever produced or would ever be produced', in a false and weak attempt to discredit a definition that has been repeated by experts in developmental biology. Here it was done by 'They are infertile' as if this impacted on whether a person is male or female.

It is important to keep track of the dishonest representations of what has been said and what has not when reading a poster who makes declarations such as that male people with CAIS should not be described as 'male people'. In this instance, the reasoning ended up being that male people with CAIS did not produce small gametes so therefore are not male people. And that to suggest that they are is somehow 'religious' and 'dogmatic'. ie. that to describe a male person with CAIS as being a male person genetically is the indoctrinated position. Whereas, it is the opposite.

needtostopnamechanging · 23/07/2025 17:44

There is one rare DSD where continuing to live as a female makes sense

these are raised as girls and the issue only discovered when they don’t menstruate. The hormones balance that they have means they don’t get the male body advantages.

I see no problem in allowing for people with essentially a disability being given some dignity and choice - it has nothing to do with transgender - it’s objective , measurable by an independent observation and doesn’t rely on stereotypes

I'm sure most people are happy to treat cais individuals as women because they look like women and so get the same shit that the rest of us do (apart from periods etc). It's not worth having conniptions about. And it's not relevant to trans.

teksquad · 23/07/2025 17:47

Yep, CAIS (Complete Androgen Insensitivity) - and completely understood and measurable, using science, unlike transness, where we are meant to just accept that somone identifies as feeling like the opposite sex, with no way of knowing whether that is genuine or hides a nefraious motive, as in so many cases that make the headlines.

Auntiebenita · 23/07/2025 17:49

Tandora · 23/07/2025 00:32

There is kareotype, there are genes (a whole system of them that related to sex-hormone signalling), there is the way that the body produces hormones, as well as how the body absorbs these hormones. these hormonal balances , and the way the body responds to them , drives the development of gonadal structures- both internal and external. And yet the systemic effects of sex hormones aren’t just restricted to governing reproductive organs, they have systemic impacts, and these include brain structures which influence psychosexual development.

I might respect your credentials in this field more if you hadn’t misspelled "karyotype"…

LittleBitofBread · 23/07/2025 17:49

Tandora · 23/07/2025 07:06

Thank you for your thoughtful and respectful question. I'll try to break them down into different parts.

First of all, I totally agree that sex matters and impacts on experience; I do not think it's irrelevant at all. But sex is complex - it is on just one thing it has multiple components and variations that all have important impacts on experience.

Given all this improvement in the understanding of the biological markers of sex, i am really interested in any research into this amongst trans people without any DSD . Is there any?

Yes, although scientific conventions wouldn't put it in exactly these terms. Sex development is layered and complex and there are minority variations. These minority variations are driven by different balances in genetic and molecular signalling, as well as how environmental factors impact on genes.

The balancing of the production and reception of sex hormones also have profound organisational effects on the brain, which underly neurodevelopment.

It is often assumed that the development of 'gender identity' (which is simply the sense/ knowledge of one's own sex) is an entirely social and simple process which (somewhat paradoxically) directly follows from what 'sex' you are observed to be at birth/ what genitals or karyotype you have. But this is far far too simplistic. As with all areas of science that relate to understanding the complex, adaptive systems of the brain there is a long way to go in our understanding (this doesn't just apply to transness it applies to all areas of neurodevelopment - ASD, ADHD, etc etc), but there is emerging evidence that transness and gender dysphoria are underpinned by variations in sex hormone signalling genes and prenatal hormone balancing. In fact if you think about it, it's foolish to believe otherwise. The brain after all - the physical structures of which underpin cognition - is part of the body and for a very long time now scientists have understood the very powerful impact that sex hormones have on the brain.

There's so much more detail I could provide, but this is the explanation in brief.

there is emerging evidence that transness and gender dysphoria are underpinned by variations in sex hormone signalling genes and prenatal hormone balancing.
Can you give us some links to some of this evidence?

Tandora · 23/07/2025 17:50

I see no problem in allowing for people with essentially a disability being given some dignity and choice

Yet some posters on this thread continue to insist on calling them male regardless of the actual person because of their own dogmatic quasi religious ideologies, it’s actually making me ill the extent to which some people think they have the right to impose labels and judgements on other people’s body and personhood.

yes, and still not relevant to the concept of trans.

teksquad · 23/07/2025 17:51

TBH as a scientist, this was my propose approach circa 2018 when my friend transitioned - see if there is a biological basis to the sudden uptick in people identifying as the opposite sex.

The TRAs were not happy .......

with the same depth of feeling, many posters feel it is extremely disrespectful to claim that a healthy bodied male has any correlation with someone who has a DSD

which led to the evil comment on the other thread.

They are male. they have functioning SRY genes located normally on a Y chromosome. They have a downstrem mutation that means they can't follow the male developmental cascade properly. They are still male. They are phenotypically female and don't benefit from a male puberty so nobody has any problem treating them as bona fide women. Why on earth does that make you feel ill?
