You all have to remember that it is not the pitch to make you sound female, but the way you use your voice. High pitch only makes you sound like a guy with a high pitched voice (like I used to be). Females talk very different than men, their pitch moves way more along the scale when they talk (more half tones). men talk pretty flat, with way less half tones.
No surgery of the world will enable you to use your voice like a female, it can (when lucky) only increase you pitch. The hard work is to use the increased pitch to talk like a woman. There is lots of information out on this on the net.
I learned to talk like this because for the last 10 or so years I had only female friends, and I adopted their speech pattern over time. This made me still sound like a woman in daily life, even with my destroyed voice, as long as I could do a whole conversation. I just sounded like a woman with a rotten sounding voice. This did not work on the phone, because the few words I talked there did not show the female way of talking, and i was misgendered almost all the time.
To summarize my experience from being identified as a male, followed by easily talking like a female, going back into the male pitch mode, and now back to female, I can only emphasize to do voice training as much as you can, prior to any surgery. Much of this can be done free of any costs by following the guidance found on the net. And after that a voice coach (I don't know what they do, cause I am with a PhD pathologist), or a pathologist may be able to help you even more.
And only after those specialists would recommend surgery as being needed, I would start to look into surgery. But remember, the surgery increases your pitch only, all the other stuff requires as much exercise as it does for people who do not have surgery! The negative aspect of surgery is the unknown outcome (I seem to remember that some ladies over at SP needed corrections), and the rather long healing time before any voice training can start!
