Before anyone discusses protocols or success rates with you, somebody decides whether you qualify and who is paying. That is the first step almost everyone meets, and it is well worth understanding early, so that a clear treatment plan comes with a clear picture of how it will be paid for.

This section is about that step: who qualifies, and who pays for what happens next. There is no single answer. Funding rules are set locally, plan by plan and area by area, and they change. So what follows describes the shape of the rules and the ranges people actually meet, and then sends you to the only documents that bind you, which are your own commissioner's policy or your own plan wording.

If you are in the UK or being treated on the NHS, start with NHS criteria. Funding is commissioned locally, so the rules a friend quotes you may simply not be yours, and the national guideline and the local offer are two different documents. If you are in the US, start with insurance and cover, which is about where cover comes from, why a state mandate may not reach your plan, and the difference between cover for finding out what is wrong and cover for fixing it.

Before either of those, most people need a referral. Getting referred covers how long you are expected to try first, why that clock is shorter past the mid-thirties, when you should not wait at all, and what the first appointment actually does. It also covers why testing both partners together saves valuable time.

Then the individual criteria, each of which has its own page because each one has its own reasoning and its own room for argument. Previous children explains the rule that most often surprises people, because a child from an earlier relationship on either side commonly ends public funding. Age limits is the criterion with the most clinical logic behind it and the least flexibility. BMI and lifestyle covers weight ranges, smoking and alcohol, where the evidence varies and the rules are usually firm.

Two pages cover who counts as a patient in the first place. Single people and same-sex couples deals with criteria written around a heterosexual couple who have been trying for two years, and what happens when that definition does not describe you. Trans and non-binary patients covers access to preservation and treatment, and how to find a clinic set up to support you well.

None of this is medical, legal or financial advice. It is what a decade of coordinating patients through clinics and sitting in on their consultations teaches you about the paperwork, written down so you can ask the right question of the person who actually holds your file. Whatever you read here, get your own criteria in writing before you plan around them.
