We're just scratching the surface of the possibilities of gene therapies.

Gene therapies are aimed at making it possible to override, delete, select or "turn on" or "silence" individual genes or mutations. That's a far cry from being able to change a person's sex chromosomes! It's basically chalk and cheese, in fact.

Changing sex chromosomes would be a tall order since they are present in each and every one of the human body's many trillion individual cells.

As well as getting close to growing organs to match someone's cells.

Please share links to the research being done showing that it's possible or likely that female cells can be used to grow sperm-producing testicles and male cells can be used to grow egg-containing ovaries. I'd be very interested to learn of this research.

My understanding is that when it comes to growing new organs from a person's cells, the organs would have to be ones consistent with the person's sex chromosomes and species. Otherwise male TRAs wouldn't be so focused on and exercised about the possibility of getting surgeries that would implant in them the uteri, ovaries and vaginas taken from the bodies of girls and women - they'd be supporting the technology that will allow them simply to grow their own. Similarly, furries and those who "identify as" animals wouldn't have rely on costumes or fake headgear any more coz they could simply grow their own animal fur/hides, paws, tails and the like - and their own kitten ears, antlers and elephant tusks too. Probably their own unicorn horns to boot.
