Informed Consent
On this page
"Informed consent" gets used in two different ways in trans healthcare, and it helps to separate them. In the narrow, legal sense, every surgery requires informed consent: you are told the risks, benefits and alternatives, and you agree. In the wider sense that people use in forums, an informed consent model means you can access surgery by demonstrating that you understand it, without needing a mental health assessment or a referral letter first. This page is about the second meaning.
What the informed consent model actually is
Under an informed consent model, the surgeon (or their team) takes on the job of confirming that you understand what you are agreeing to. There is no separate gatekeeper. You have a consultation, you may fill in a detailed questionnaire, and the surgeon decides whether you have capacity to consent and whether the procedure is appropriate. No therapist is involved unless the surgeon has concerns.
This is how most cosmetic and elective surgery already works. Someone getting a reduction mammoplasty for back pain does not need a psychologist's letter; the surgeon assesses them. Informed consent for gender-affirming surgery applies the same logic.
It is not "no assessment". A good informed consent process still asks about your history, your mental health, your support at home, your understanding of the recovery, and your expectations. It just does not outsource that to a third party.
Where it is offered
United States. Informed consent is common for top surgery among private surgeons when you are paying out of pocket. If you use insurance, the insurer's policy overrides the surgeon's, and almost every US insurer still requires at least one letter. So in practice "informed consent" in the US usually means "self-pay". Hormones have been available on an informed consent basis at many clinics for years; surgery has followed more slowly, and mostly for chest surgery. Genital surgery on a pure informed consent basis is rare, partly because hospitals require letters as a condition of granting operating privileges, regardless of what the surgeon thinks.
United Kingdom. Some private top surgeons operate on a modified informed consent basis, though many still ask for a letter from a psychologist or GP because it protects them under GMC guidance. The NHS does not use informed consent for surgery; the gender clinic assessment is mandatory. Private genital surgery in the UK is limited and generally requires letters.
Thailand and other surgical tourism destinations. Clinics vary. Some ask for a psychiatrist's letter (which is a legal requirement in Thailand for some procedures), some accept a letter from your home clinician, some ask for nothing beyond a consultation. See Surgery Abroad.
How it differs from a letter pathway
| Informed consent | Letter pathway | |
|---|---|---|
| Who assesses readiness | The surgeon | An independent clinician, then the surgeon |
| Typical time to surgery | Consultation to date, often weeks to months | Add time to obtain letters, plus insurer or clinic approval |
| Who pays | Usually you | Usually an insurer or public system |
| Documentation you need | ID, medical history, consent forms | The above plus one or two letters, often hormone history |
| Where it is widely available | US private top surgery, some UK private surgeons, some clinics abroad | Everywhere else |
What the consultation looks like
Expect the same conversation you would have with any surgeon, with a bit more emphasis on expectations and permanence. You will be asked how long you have wanted the surgery, what you expect it to change, what your plan is for recovery and support, and whether you have any conditions that affect healing. You may be asked to sign a longer consent form than usual, sometimes with a short written explanation of the procedure in your own words. That is not a test; it is the surgeon documenting that you understood.
If the surgeon has concerns, they may ask for a letter after all. That is within their rights and does not mean you have been rejected. It usually means something in your history made them want a second opinion on readiness or timing.
Pros and cons, honestly
The upside is speed and autonomy. You skip a step that many people find patronising, and you avoid the wait and cost of finding a letter writer.
The downside is that informed consent mostly exists where you are paying yourself, so it ties you to the self-pay price. It also puts more weight on your own judgement about readiness and about the surgeon. There is no independent clinician to say "have you thought about..." and some people find they miss that.
The other real risk is that informed consent gets used as marketing. A clinic that promises "no letters, no questions" is not necessarily doing you a favour. The point of the model is that the surgeon does the assessment properly, not that nobody does it. Ask what their process is. If the answer is "sign here", think twice.
If you want it but can only get a letter pathway
Get the letter. It costs a few hundred dollars or pounds through a single-session service and takes days, which is the same order of magnitude as finding a good surgeon anyway. Letters of Support covers the fastest ways to do it. Informed consent is worth having as a principle; it is not worth delaying surgery over.
