But do you have any actual evidence that this can happen? Does anyone?
What do you mean by evidence?
With an apology to the OP for the derail, I will explain whilst having to experience of trans I very much emphasise with her
Last year one doctor was genuinely considering admitting DS to hospital for munchusens by proxy. the Doctor couldn't fit Ds's symptoms into something he knew and understood, it simply couldn't be happening the way i was being reporting it and so the obvious conclusion was i was harming my child. (Thankfully his colleague felt differently)
One year later, the right test results and a few very clever Doctors, DS is diagnosed.
Exactly as i had reported the symptoms but a slightly different medical pathway than is currently documented. They don't really have all the information behind my DS's SN, chances are DS will end up in the medical books somewhere. (Along with an awful lot of other children with disperate unexplained symptoms who are part of some pretty major breakthrough studies). It's is amazing how little we actually know about how the body and how and why it develops beyond simple baseline mechanics.
Up to the point of diagnosis the only "actual evidence" was observation. And that was subject to interpretation. Does that mean it wasn't happening? No of course not. It just meant we didnt understand it.
I wonder if the Doctor who now finds himself on the wrong side of DS' personal history will ever comprehend the idea that because we only have observational evidence of something it doesn't mean it doesn't exist.
Now treatment is not an area I can comment on, i have no baseline and no experience. Other than your last sentence reminds me of a Doctor who 5 years ago told me I by asking for a specific unpleasant intrusive test i was ridiculous And clearly wanted to harm my child, the doctor who suggested it was an irresponsible unethical nutjob. Guess which test proved my son's condition...
So no despite the lack of evidence beyond people's experience, it's not hard for me to believe that systems that govern development stuff up in ways we don't yet understand
Of course i may prove wrong in the long run. But so might much of the gender/sex stuff. In the end we are only making sense of what we experience based on current knowledge.
What we really need to be aware of is how limited that currently knowledge is.
