Informed consent HRT means a doctor prescribes gender-affirming hormones based on your understanding of the risks and benefits, without requiring psychological assessment or a diagnosis first. It contrasts with gatekeeper models, where clinicians decide whether you qualify. NHS waiting lists now run to years, making private and online providers the realistic route for most people.
What does informed consent actually mean in this context?
The phrase sounds bureaucratic, but the idea is simple and it is the same principle that runs through every other area of medicine. When you go to a doctor for most treatments, they explain what the treatment does, what the risks are, what might happen if you do not have it, and they ask whether you want to go ahead. You decide. They prescribe. That is informed consent.
In gender-affirming care, the informed consent model applies the same logic. A clinician goes through what oestrogen or testosterone will do to your body over time, explains the monitoring you will need, covers the things that are reversible and the things that are not, and asks whether, knowing all of that, you want to begin. If the answer is yes, you begin. What it does not require is a letter from a psychiatrist confirming that your gender identity is genuine, a period of psychological evaluation, a formal diagnosis of gender dysphoria, or a gatekeeping committee deciding whether you have suffered enough to qualify.
WPATH, the World Professional Association for Transgender Health, and the Endocrine Society both support informed consent as the basis for initiating gender-affirming hormone therapy in adults. This is not a fringe position. It reflects where the evidence and the ethics of good care have landed.
What is the gatekeeper model, and why did it exist?
The traditional pathway, still largely in place in NHS gender services, works differently. You are referred to a specialist gender clinic. You wait. You attend assessments, often multiple, with psychologists or psychiatrists whose job is to evaluate whether your gender identity is stable and genuine enough to warrant medical intervention. You receive a diagnosis. Only then does a clinician prescribe hormones.
The intention behind that model was protective, a response to an era when trans identities were pathologised and the medical profession was cautious, sometimes to the point of cruelty. The assumption embedded in the gatekeeper approach is that hormones are so significant a step that patients cannot be trusted to weigh them up themselves, and that an external authority needs to verify the need before care begins.
The problem is that this assumption does not apply anywhere else in medicine. We do not make people prove the validity of their suffering before we treat it. We explain the options, we discuss the risks, we give people the information they need, and we let them decide. The gatekeeper model asks a different question entirely: not "do you understand and consent?" but "do we believe you?" That is a fundamentally different thing, and many trans people have spent years discovering how dehumanising it feels.
What NHS waiting lists actually look like now
People tell me, again and again, about referrals made years ago that have gone nowhere. The NHS has never had the capacity to meet demand for gender services, and the combination of rising referral numbers, clinic closures, restructuring following the Cass Review, and a long-term failure to train enough clinicians has created a situation where realistic waits run to several years in many parts of the UK. For an adult who needs care now, a wait of that length is not a minor inconvenience. Unwanted puberty changes cannot be undone. Dysphoria does not pause while a waiting list moves.
Some people are referred to their GP in the hope that a GP will bridge prescribe, taking over prescribing after an initial assessment or prescription from a gender specialist. In practice, many GPs are reluctant to do this, either because they lack confidence in this area, because their practice has a policy against it, or because the specialist pathway that would normally support them has broken down. Delay is never neutral. Withholding care is a decision with consequences, not an absence of one.
What private informed consent care looks like in practice
Private providers operating on an informed consent model generally work like this. You make contact, often online. There is an initial consultation with a clinician, usually a doctor with experience in gender medicine, who goes through your history, your goals, your current health, and the relevant risks and benefits. If everything is in order and you want to proceed, a prescription follows. You are typically expected to have blood tests before starting and at regular intervals afterwards, to monitor hormone levels and check for anything that needs attention.
The whole process, from first contact to prescription, can take days to weeks rather than years. That speed is not recklessness. It is what happens when you remove the layers of assessment that were never clinically necessary in the first place, and focus instead on the things that actually matter: your health, your understanding, and your decision.
GenderGP is one provider in this space, founded specifically because NHS waiting lists could not reach the people who needed care. They use current international standards and are staffed by clinicians who specialise in this area. If you are ready to begin or continue treatment, or if your own doctor has refused to prescribe or bridge prescribe, their website is at gendergp.com.
What does it cost, and is it realistic for most people?
Cost is where the informed consent model runs into real difficulty. Private care is not free, and for people on low incomes the financial barrier can be just as absolute as the waiting list. Typical costs in the UK private sector include an initial consultation fee, ongoing prescription fees, and blood test costs, which may be covered by a private provider's own monitoring or may fall to you to arrange through your GP or a private laboratory.
The figures vary between providers and change over time, so I am not going to name specific numbers here and risk giving you something out of date. What I can say is that for many people the monthly ongoing cost of hormones themselves, once stable on a prescription, is relatively modest. The heavier costs tend to be front-loaded in the initial assessment and titration period. Some providers offer sliding-scale fees or payment plans; it is always worth asking.
For people who genuinely cannot afford private care and cannot wait years for NHS treatment, the DIY route, obtaining hormones without a prescription, has become a reality for a significant number of trans people. I understand exactly why. The risk with the DIY route is not that hormones are inherently dangerous, but that without monitoring you will not catch the things that need catching, and without a clinician you will not know if your dose is right. If you are in that position, harm reduction matters. Getting blood tests done, even if you are not on a formal pathway, is better than not getting them done. If a private pathway becomes accessible to you, move to it.
Does the informed consent model apply outside the UK?
Yes, and in many countries it is more established than in the UK. Planned Parenthood in the United States has been offering informed consent HRT across many of its clinics for years, and a number of countries in Europe and elsewhere have moved substantially away from psychiatric gatekeeping requirements. The UK is, by international standards, behind rather than ahead on this.
If you are outside the UK, the principle is the same: look for a provider that does not require a psychiatric referral or extended psychological assessment before prescribing, that uses current international guidelines, and that has clinicians with real expertise in gender medicine. Your own country's trans health networks or advocacy organisations are usually the best source of up-to-date recommendations on local providers.
What about younger adults and the question of age?
Informed consent models for adults generally apply from 18 upwards, though some providers in some jurisdictions extend this with appropriate processes to people aged 16 or 17. For people under 16, the picture is more complex and is governed by specific legal and clinical frameworks around competence and consent. In the UK, access to gender-affirming medical care for under-18s has become significantly more restricted, and the situation is continuing to change. If you are a young person looking for information about what is available to you, the right starting point is a conversation with your own doctor, who can find the right specialist if and when the time is right.
What the informed consent model does not mean
It does not mean no clinical oversight, no monitoring, no blood tests, and no medical relationship. It means the basis of that relationship is your understanding and your decision, not someone else's verdict on whether you qualify. A good informed consent prescriber takes your health seriously, monitors your levels, adjusts your dose, checks in on how you are doing, and flags anything that needs attention. The difference is that they are doing that as your doctor, not as your gatekeeper.
It also does not mean that every question about your health or history is irrelevant. A clinician working on an informed consent basis still needs to know whether you have conditions that interact with hormone therapy, whether there is anything in your history that changes the risk profile, and what other medications you are taking. The consultation is real. What is missing is the part where they decide whether your gender identity is valid enough to deserve treatment.
