Welcome, I’m glad you’re here
You’ve done the thinking most people never have to do. You’ve looked at your life and seen that, if you want a child, you may be doing it on your own. Perhaps you still hope someone turns up later. Both can be true.
What you probably don’t know is how fertility treatment actually works: what the tests mean, and who is looking out for you. No one explains it before you start. Most women over 40 learn as they spend – which is a hard strategy, when it’s one income funding treatment.
This is the ebook I wish I’d had. When you walk into your first consultation, you’ll know what to ask and what to watch for, and you won’t have spent anything finding that out.
First, how I learned, the expensive way.
My story
Days after I decided to pursue treatment at 42, I paid for a set of fertility tests. I was in India at the time. A comprehensive set of tests cost around £200. One of the core tests requested by every clinic is the Anti-Müllerian Hormone (AMH), often described as a marker of ovarian reserve. My result came back very low. I read the number in a café and cried, fearing I’d waited myself out of motherhood.
What I didn’t know then was that the figure in front of me wasn’t the whole story, and that the clinic reading it back to me had reasons of its own for choosing to share it in the unit that sounded most alarming. Focusing on that lower figure made me panic.
I went ahead with IVF anyway. Two cycles in Europe, operations undertaken alone with no one in the room to support me. Both were unsuccessful, and both clinics casually recommended donor eggs. I was devastated.
One clinic, in Spain, actually refused to treat me with my own eggs. This clinic had accidentally leaked my medical data to another patient. I only learned about it when the patient emailed to explain. It didn’t seem like the clinic wanted to update me. So perhaps their refusal to treat me was actually a way to distance themselves. Either way, I took it as another blow. Were my eggs really unusable?
Two months later, I conceived naturally with a known donor met through a chance encounter. I was almost 44. He was 38.
Some people ask, “Was it all worth it?” A better question is, “What could have been easier?” The answer, every time: planning the treatment itself — knowing what to expect, and how to manage the clinics and doctors I was investing in, rather than finding it all out as I spent thousands.
Crying in that café, alone, frantically Googling to understand what my AMH result actually meant — that’s the moment that helped me launch Solo Fertility 40s. Because no woman should go into treatment panicking and alone, grieving time she feels she’s already lost before she’s even started.
Writing about my own treatment, the industry, and writing on Substack broadcast my experiences to women worldwide. In fact, women across 35 countries are reading the stories. Many of them have emailed me about their own experiences.
This helped me make three big realisations:
- Fertility treatment is a business, a large and competitive one, and understanding how it works commercially is one of the most useful things you can do before you part with any money.
- No one advocates for you unless you do it yourself. You are a patient. You are also a paying customer. Both are true at once, and the system works better for you when you remember it.
- Navigating the fertility system can be learned. It falls broadly into five steps, which I talk you through below.
What follows is how I wasted precious time and money (and so much more). I funded my treatment with my own salary. I also entered treatment extremely alone.
You get to prepare before you spend five figures on one of the most important decisions of your life.
There are five steps to consider and they’re relevant whether you’re thinking about treatment but simply want to know what’s involved. Or you’re ready to get going but you have no idea how.
Keep track of your progress using the checklist at the end.
Solo, and over 40
Most fertility content assumes someone else is in the room: a partner to ask the follow-up question, and to say afterwards, “that didn’t sound right.” Doing this solo means nobody sense-checks what you’re told. You hear the recommendation and the price alone, and you decide alone.
Clinics vary a great deal in how they handle that. Some are genuinely supportive of solo women. They ask who your support is and explain things twice. Others really aren’t, and you’ll feel the difference in the first consultation.
Add being over 40 and it compounds. You’re up against time, so every decision feels urgent. You’re funding it from one salary, so a wrong turn costs more and there’s no second income to absorb it. Each makes the other harder. The steps below are written with that in mind.
You don’t need to do this alone
I know how it feels to be alone through thinking about, planning and having treatment. Perhaps you’ve not told anyone and you’re wondering if it’s a crazy idea as a woman over 40? You want to talk with people who get it.

Step 1
Preparing to start: what they don’t tell you about your tests
Back to that café. My AMH result was just written on a piece of paper. I had no context to explain what it really meant. Then my first fertility consultation – with a well established Spanish clinic – advised me to get moving, and fast, because of my low AMH. I had little time to prepare.
Here’s what I learned afterwards.
Your test results
AMH can be measured in two different units, pmol/L and ng/mL, and the same underlying result looks very different depending on which one is used. Mine was 0.31 ng/mL, which is exactly the same result as 2.2 pmol/L. The clinic used the lower-sounding figure to justify rushing me into treatment. Nobody mentioned there was another way to read it. I was given urgency instead of information.
A low AMH is one data point. It isn’t a verdict, and on its own it doesn’t tell you whether treatment can work for you. That is a conversation for your doctor, with your full picture in front of them.
The business of fertility
That first consultation taught me something else too: fertility treatment is a business, and not a small one. In 2024 the global fertility services market was worth an estimated $46.1 billion, and every clinic in it has a sales target. Some of the biggest names rank on page one of Google for terms like “IVF over 40” — prized, expensive keywords. A page-one ranking and a polished website tell you about the size of a marketing budget. They tell you nothing about success rates or how you’ll actually be treated once you’re in the room.
Self-advocacy
That’s the thing nobody says out loud at the start: you are a patient, and you are also a paying customer. Both are true at once, and no one advocates for the second half of that unless you do it yourself. Go into every consultation assuming you’ll need to ask the follow-up question, not assuming it’ll be offered.
What to do
Before your first consultation:
- Ask which unit your AMH is reported in, and what that specific figure means for you, rather than simply whether it counts as “low.”
- Ask how the clinic’s success rate is calculated, and for which age group.
- If a consultation feels rushed, say so. You’re allowed to leave the room and come back. Nothing has to be decided while you’re sitting in the chair.
This is the pattern I use for every decision in this process now: get the specific figure, then work out who benefits from the version you were just given.
Step 2
Creating your financial plan: don’t spend it all on one attempt
Here’s something I wish someone had said to me before I started. A woman over 40 may need several cycles, often three or more, to produce a healthy embryo and, with luck, a birth. I didn’t know that, so I paid cycle by cycle, panicked at each turn, changed clinics three times, and spent more than I needed to. For context, the UK birth rate per embryo transferred in 2024 was 8% for women aged 43–44, against 38% for women aged 18–34 (HFEA).
Had I understood it at the start, I’d have gone looking for a multi-cycle package from the beginning. Plenty of clinics offer them. Some don’t require the whole amount upfront, and some build in a refund if you conceive on the first attempt. Planning for more than one cycle isn’t pessimism. It’s what stops you making expensive decisions under pressure. If it works first time, that’s a gift rather than the plan.
One thing worth holding onto as you compare clinics: price and success rates don’t always move together. The cheapest option isn’t automatically a false economy, and the most expensive isn’t automatically the safest pair of hands. Look at both separately, and ask what’s actually included in the number you’re quoted.
What to do
These are the costs that catch people out, on top of the headline cycle fee:
- Medications, often an extra £1,000–£3,000 depending on your protocol (more on costs)
- Monitoring scans and bloods, charged separately
- Donor sperm purchase and import fees, if you’re using them
- Embryo storage
- Add-ons — some evidenced, many offered because a frightened patient will pay for anything that sounds like it might help
Before you pay a deposit:
- Ask for all of it itemised in writing.
- Ask specifically about multi-cycle pricing, even if you’re only planning for one round.
The planning principle underneath this one: price every decision for three cycles, not one, even if you only need the first.
Step 3
Choosing the right clinic: not just the closest
A few hours reading fertility forums confirmed what I’d suspected. Clinics vary enormously, not only in price but in ethics and in how they treat the women in front of them. I wasn’t convinced I’d get the best care, or the best chance, simply by defaulting to the nearest option. A UK clinic was beyond my budget anyway, so I looked further afield. People travel for dental work and cosmetic surgery, and fertility treatment is no different.
To choose my third clinic, in Greece, I did more than fifteen consultations across six countries. It was exhausting. But where you’re treated is one of the most consequential decisions in this whole process, and I’d already got it wrong twice.
What to do
Some clinics won’t treat women over 44 at all. Others will, and shouldn’t. Going abroad isn’t right for everyone, and even at home the gap between a good clinic and a poor one is wide.
- Look for genuine experience treating women over 40, not a general practice willing to take you on.
- Ask how the clinic supports solo patients in practice: who you can call between appointments, and what happens on retrieval day when nobody’s there to take you home.
- Seek out impartial patient accounts rather than the clinic’s own marketing.
- Stay a little sceptical in the forums too, because some groups run on affiliate arrangements where members are rewarded for positive reviews.
- Read success statistics slowly. The way they’re presented is a choice the clinic has made.
My rule for choosing anything in this process now: the easiest option to find is rarely the one worth choosing without checking three others against it.
Step 4
Finding the right doctor: more than credentials
Finding the right doctor isn’t only about qualifications. It’s about whether you feel heard in the room, what your instinct tells you once you’ve left it and how you have been treated throughout the consultation stage.
This is closer to an interview than you might expect, except you’re the one doing the assessing. That matters, because you could be working with this person for months, possibly years.
I learned the difference the hard way. After all those consultations, I realised I wasn’t just looking for a skilled doctor. I was looking for one with real, specific experience treating women over 40. One who would be with me through as many IVF cycles using my own eggs as I could afford. I didn’t want to be shifted over to donor eggs.
Not a good doctor who sees the occasional older patient, but someone who does this all the time. My first doctor was competent and cold, and his manner left me uneasy. The relationship carries as much weight as the medicine.
What to do
- Pay attention to how they explain things, and whether you can ask questions without being made to feel like a nuisance.
- Ask about their protocol. A good one is tailored to you. A doctor pushing a standard approach without explaining it, or steering you toward donor eggs when you’ve said you want to try with your own, is telling you something worth hearing.
- Expect close monitoring, with scans and bloods through your stimulation. Every cycle behaves differently, and a good doctor adjusts as yours unfolds.
I suggest these recommendations as a woman who completed over 15 consultations across six countries.
Step 5
Your constellation of care: you don’t have to work it out alone
Treatment as a solo woman isn’t only about the clinic or the protocol. It’s about staying steady in the middle of it. You’ll be making significant medical and financial choices, and carrying the emotional weight of them, largely on your own. There’s no partner to share the load, and friends, however kind, don’t always understand what this actually involves.
So here’s what I wish someone had told me at the start: build a constellation of care. At the centre of it is you, the anchor. You decide who stays in your orbit and who drains you. Your constellation is a small, deliberately chosen group of people who help you feel supported enough to make the big calls and to speak up for yourself.
You can’t outsource your body, but you can design the support around it, and it’s far easier to build before you’re overwhelmed than in the thick of it.
What to do
That team is yours to choose.
- Pick the people: a therapist, a few friends who genuinely get it, an online community, a fertility coach — whoever leaves you feeling less alone and more capable.
- You don’t need everyone, you need a few of the right people. Not everyone in your life will understand, and that’s alright.
- Some relationships will feel draining while you’re in treatment. Stepping back from them for a while is allowed.
The planning principle behind this one: build the support structure before the hard weeks, not during them. Nothing about a constellation of care can be assembled at 2am when you actually need it.
Before you spend anything
You now have the framework most women only assemble when treatment is underway – and they’re spending thousands. The five steps, in your hands, before you begin. That’s further ahead than I was, and further than the system tends to let you get on your own.
I know what it’s like to be exactly where you are right now — the version of me sitting in that café, reading a number I didn’t understand, is the reason this ebook exists. You’re not behind. You’re ahead of where I was, because you have this before you’ve spent anything.
Before you go further, here’s what to carry with you from each step.
Before your first consultation
Before you commit to a clinic financially
Before you choose where to be treated

Donor conception
There’s a layer beneath these five steps that an ebook can’t reach, and it’s where a lot of women get stuck. The deeper clinical decisions, particularly around donor sperm and donor eggs, are more nuanced over 40 than most clinics let on. And then there’s the harder, less-discussed work of doing this alone and building a plan that fits your actual budget and timeline rather than a generic one.
Two decisions here don’t come with a script. Sourcing a sperm donor — bank or known donor, import logistics, legal parentage — rests entirely on your own judgement, with no one else’s to weigh it against. And if a clinic recommends donor eggs, it’s worth knowing whether that’s about your specific numbers or the default recommendation for anyone your age.
This is a weighty decision, and nobody else’s view should decide it for you. Mine, for what it’s worth: I was willing to accept the help of a man who had offered his cells to help me grow my family. If my own eggs hadn’t created a viable embryo, I was also open to accepting the help of a woman who had offered hers, for the same reason.
A few places worth going for support beyond this ebook. The Donor Conception Network for the social and emotional side of donor conception specifically — a UK charity supporting donor conception families for over 30 years. A BICA-accredited fertility counsellor can talk through both decisions with you directly. Paths to Parenthub is a UK community and webinar library for people building a family through donor conception, with a membership for solo parents. It runs on a paid subscription.
Deeper support
The Briefing Room goes further still, for those who want proper support for pre-treatment planning, before you spend five figures.
It’s a six-week, cohort-based programme for solo women over 40, with hand-picked specialists experienced in treating this age group specifically. Instead of paying for a separate 1:1 consultation with each expert, we speak to each of them together as a group. It is the most holistic, affordable way to get the vital input you need upfront – before you’re spending thousands. Find out more about the Briefing Room →
