Before anyone gives you a date, somebody has to decide you are eligible. Who that somebody is, and what they want to see, depends on where you live, who is paying and which surgeon you choose. This section takes the common requirements one at a time so you can work out which of them apply to you and start collecting the slow ones early.

Most of what you will be asked for traces back to one document. The WPATH Standards of Care are the guidelines that surgeons, insurers and public health systems lean on. They are not law, and they are read tightly by some clinics and loosely by others, but once you know what is in them you will understand why you are being asked for a particular piece of paper.

The requirement that holds people up is letters of support. Vaginoplasty commonly asks for two, while breast augmentation often asks for one and sometimes for none. Getting them takes anything from a fortnight to a couple of years depending on your route, so this is the thing to start before you start anything else. That page covers who can write a letter, what it has to say, and what to do when the only route you can find is a waiting list.

Not every surgeon works that way. Some run an informed consent model, where you and the surgeon settle it between you and no therapist is involved. It is more common for breast and facial work than for genital surgery, and more common with private surgeons than with funded pathways.

Then come the physical requirements. Some surgeons set a minimum time on oestrogen and anti-androgens and some do not, though almost all of them want a chest and a body that have stopped changing. Many work to a BMI ceiling, and it moves around by surgeon and by procedure. Nearly all of them will tell you to stop smoking, vaping and nicotine in every form for weeks either side, and they are strict about it, because moved skin lives or dies on very small blood vessels.

One prerequisite is not paperwork at all. If you are heading for vaginoplasty, permanent hair removal on the area the surgeon will use has to be finished before your date rather than chased around it, and that runs over many months. It belongs on the same early list as your letters. Start here sets out where it sits in the wider timeline.

There are separate pages for people under 18 and for non-binary people, because the rules and the reactions you get from clinicians tend to be different.

None of this is medical advice. It is what I have pieced together from years of walking patients through Bangkok consultations, from surgeons' published criteria, and from what people have told me went wrong. Always check the written requirements of the specific surgeon, clinic or programme you are dealing with. They set their own rules, those rules differ between countries, and they change.
