The NHS fertility pathway is not one pathway. It's thirty-six, one per Integrated Care Board in England (reduced from 42 following April 2026 mergers), plus the devolved nations, and what you're entitled to depends on a postcode you didn't choose.
Once you know that, a lot of what feels like personal bad luck reveals itself as a system you're navigating, not a system that's failing you alone. The work is learning to navigate it.
The standard GP referral threshold is twelve months of trying without conceiving, six months if you're 36 or over, or if there's a known reason to investigate sooner (irregular cycles, known conditions, previous surgery, male-factor history, same-sex couples or solo parents using donor gametes).
The 'sooner if there's reason' clause can be broader in practice than it's sometimes applied, and it's worth knowing it exists before the conversation. If the timeline feels at odds with your specific history, that's worth raising.
Initial investigations are largely the same everywhere: hormone bloods (day 2–5 and day 21 of your cycle, or fixed-day if your cycles are irregular), AMH, thyroid function, prolactin, a pelvic ultrasound, and a semen analysis for the male partner. What varies is how quickly they happen and whether anyone tells you the results in plain English.
Patients can normally request copies of their own results, ask for them. If the language is opaque, that's a flag to ask for translation, not a flag that you're being difficult.
Funding for actual treatment, IUI, IVF, ICSI, is where the postcode lottery bites hardest. NICE recommends three full IVF cycles for eligible women under 40 and one cycle for women 40–42. Most ICBs fund less than that. Some fund one cycle.
A few fund zero. Eligibility criteria layered on top, BMI windows, smoking status, no living children from any relationship, age cut-offs, partner age, narrow it further, and they're not always written down where you can find them.
The single most useful thing you can do early is find your ICB's fertility policy in writing. Search '[your ICB name] fertility policy' or 'NHS funded IVF [your ICB]'. Read what you're actually entitled to before the first GP conversation.
Knowing the policy doesn't change it, but it changes the conversation, you're no longer asking what's possible, you're confirming what's already documented.
What to ask your GP, and how to make sure the conversation covers what it should
Three questions worth bringing to the referral conversation. First: 'Based on my history, do I meet the criteria for early referral, or do I need to wait the full twelve months?' This puts the criteria in the room without making it adversarial. Second: 'What's the current waiting time from referral to first specialist appointment in our area?' If they don't know, that's fine, it's usually available on the local ICB site. Third: 'Can I have copies of my blood results as they come back?'
Patients can normally request these, and having them in your own file means the next clinician you see doesn't start from zero. If the appointment ends without a clear plan for investigation, or if a semen analysis hasn't been discussed alongside your bloods, those are both worth raising at the next appointment, ideally in writing so there's a record.
