FTM Surgery for Under-18s
On this page
This is the part of the site where the answer depends most on where you live and when you are reading it. The clinical guidelines have not changed much in the last few years; the law and the political climate have changed a great deal. What follows is accurate as of 2026 as far as I can make it, but check the current position where you are before making any plans.
What the clinical guidelines say
The WPATH Standards of Care (SOC8, 2022) treat adolescents in a separate chapter. The published version does not set minimum ages for surgery; a draft included them and they were removed in a correction. What it says instead is that chest surgery can be considered for adolescents on a case-by-case basis, with parental or guardian involvement, a multidisciplinary team, and evidence of sustained gender incongruence over time. It says genital surgery should generally not be done until the person reaches the age of legal majority in their country. The Endocrine Society's guidance is similar in substance.
In plain terms: the guidelines allow for top surgery in some older teenagers with careful assessment, and do not support genital surgery under 18. Hysterectomy, oophorectomy, metoidioplasty and phalloplasty for minors are essentially not done anywhere by reputable surgeons.
The practical picture by region
United Kingdom. The NHS does not provide gender-affirming surgery to anyone under 18, and never has. Following the Cass Review (2024), NHS services for under-18s were restructured, puberty blockers were restricted to research settings, and the threshold for any intervention became more conservative. Private top surgery for under-18s in the UK is, in practice, not available: UK surgeons will not operate, and the regulatory environment makes it very unlikely that will change. At 18 you can access private top surgery immediately if you can pay; the NHS adult pathway involves a referral to an adult gender clinic and a wait measured in years. See NHS Pathway and Waiting Lists.
United States. Historically, top surgery for 16 and 17 year olds with parental consent and letters from mental health professionals was available from some surgeons, with a small number operating on younger patients in exceptional cases. That has changed sharply. As of 2026, roughly half of US states have laws banning gender-affirming surgery for minors, often alongside bans on hormones and blockers, and federal actions since 2025 have pushed hospitals in the remaining states to pause or end surgical care for under-18s and in some cases under-19s. Some private surgeons still operate on 17 year olds in states without bans, but it is a shrinking number and subject to rapid change. If you are a minor in the US or a parent of one, the current state of play is a legal question as much as a medical one, and it is worth getting up-to-date advice from an organisation that tracks it rather than relying on any static page, including this one.
Canada. Provincial systems generally fund top surgery from 18, with some provinces allowing it for 16 and 17 year olds with parental consent and appropriate assessment. Genital surgery is 18 and over. See Coverage in Canada.
Australia. Top surgery for under-18s is legally possible with parental consent and specialist assessment, though it is uncommon and mostly limited to 16 and 17 year olds under care of a gender service. Court approval, once required for some treatments, is no longer needed where parents and clinicians agree. Genital surgery is 18 and over. See Coverage in Australia.
Europe. Most countries set 18 as the minimum for any surgery, with the Netherlands and Belgium historically allowing chest surgery slightly earlier in some cases. Several countries have tightened rather than loosened their approach since 2022. See Coverage in Europe.
What is normally required, where it is possible
Where top surgery for a minor is available at all, the requirements are stricter than for adults:
- Consent from all legal guardians
- Assessment by a mental health professional experienced with adolescents, often over an extended period rather than a single session
- Usually a second letter or a multidisciplinary team recommendation
- Typically some period on testosterone, though this is not a WPATH requirement for chest surgery at any age
- Evidence of long-standing, consistent gender incongruence
- A surgeon willing to operate on minors, which is a smaller pool than for adults
Preparing while you wait
If surgery is not available to you until 18, there is a lot of useful groundwork that can be done in the meantime, and most of it is what adults are told to do anyway.
- Get established with a clinician who can eventually write a letter. A therapist who has known you for two years can write a stronger letter than one who met you last week. See Letters of Support.
- If you are on testosterone, the wait is doing useful work. Chest fat redistribution and, if genital surgery is a future goal, clitoral growth both take time.
- Research surgeons and understand techniques, so that at 18 you know what you are asking for. See Which Technique.
- Start saving or understanding the funding route. Private top surgery costs are on Costs by Procedure.
- Stay nicotine-free; see Smoking and Nicotine Before Surgery.
