You really should see Ryan Johnson’s doctor. I know it’s not “canon”, but the woman who played the doctor was quite good, it wasn’t a joke, and it was 30 years ago. There were 4 episodes, the 4th one being the best.
Ryan has a website that can be found with a modest bit of googling.
I am intrigued - will certainly give it a go.
On a separate note I don’t get all the selective cherry-picking of past episodes to try and discredit the notion that a Gallifreyan can’t change sexes - we’re told, and have been shown, that they can change colour, age, personality, character, memory, and sex - so it’s hardly a big surprise…
and just because it hasn’t been mentioned in the earlier Who content doesn’t mean it’s any less correct.
The Doctor will be a woman - big deal.
I just hope Jodie Whittaker gets some decent stories and lines - she’s a talented and interesting actress - and that the series does well.
