Start Here: Your Guide to Fertility Treatment

What gets checked first

Almost nobody starts with treatment. Almost everybody starts with testing, and the testing looks at both partners, because in couples with male and female partners a male factor is involved in something like a third to a half of cases, on its own or alongside a female factor. A workup that tests only one person is half a workup.

On the male side it begins with a semen analysis: volume, sperm count, how many are moving and how many are normally shaped. It is cheap, it is quick, and it changes the plan more often than people expect. One poor result is usually repeated after a few weeks, because the numbers swing.

On the female side there are four questions. Is there an egg supply? That is ovarian reserve, measured by an AMH blood test and an antral follicle count on ultrasound. Both estimate how many eggs are left, not their quality, and neither predicts whether you can conceive naturally. Is ovulation happening? A hormone panel across the cycle, typically FSH, LH, oestradiol, progesterone, prolactin and thyroid function, answers that. Are the tubes open? A dye test, an HSG or the ultrasound version, checks whether egg and sperm can meet. Is the uterus normal? Ultrasound, sometimes with a saline scan or a hysteroscopy, looks for fibroids, polyps, scarring or a septum.

The general rule for when to start is twelve months of trying, or six months if the female partner is over 35, and straight away if there is an obvious reason such as absent periods, known tubal damage, previous cancer treatment or a very poor semen analysis. Single women and same-sex couples skip the waiting entirely, since the route in is donor sperm from the start.

Before your first appointment

Ask for copies of every result, not just the summary. Numbers like AMH, antral follicle count and total motile sperm count travel with you to any clinic and stop you paying for the same test twice.

The ladder of treatment

Fertility treatment is a ladder, and most people climb it rather than starting at the top. Where you get on depends on what the tests found and on age, which shortens the time you can afford to spend on the lower rungs.

Timed intercourse and ovulation induction. Tablets such as letrozole or clomifene, sometimes injections, to make ovulation happen or happen more predictably, with scans to track it. The first choice when the problem is ovulation, as in PCOS, and the cheapest thing on the ladder.

IUI, intra-uterine insemination. Prepared sperm placed directly into the uterus around ovulation, usually with mild stimulation. It needs at least one open tube and reasonable sperm. Per cycle the odds are modest, typically a low-teens percentage or less and lower over 38, so it is normally tried for a few cycles rather than indefinitely. It is also the standard first route for single women and female same-sex couples using donor sperm.

IVF. Injections for roughly ten to fourteen days to grow multiple follicles, egg collection under sedation, fertilisation in the laboratory, five or six days of embryo culture, then one embryo transferred and any others frozen. It bypasses blocked tubes, handles unexplained infertility and low reserve, and is where most people end up if the lower rungs do not work.

ICSI. IVF with a single sperm injected directly into each egg, rather than eggs and sperm left to fertilise on their own. It exists for male factor, and for that it is a genuine solution. Used where there is no male factor it mostly adds cost without adding babies, which is worth knowing because in some clinics it is the default.

Donor gametes and embryos. Donor sperm, donor eggs or donated embryos, when your own gametes are the limiting factor. Donor eggs in particular change the odds substantially, because success then tracks the donor's age rather than yours. The law here varies more than anywhere else in fertility: whether donors are anonymous, whether they can be paid, how many families one donor may create, and what a surrogacy arrangement is allowed to be, all differ by country. Thailand, for example, restricts commercial surrogacy and sex selection for foreigners. Check the rules where you intend to be treated before you plan around them.

Surgery sits alongside the ladder rather than on it: removing a polyp or fibroid, treating endometriosis, repairing a varicocele, or retrieving sperm directly from the testicle when there is none in the ejaculate.

Freezing is a separate track

Freezing is not a treatment for infertility. It is a way of moving fertility forward in time, and its timing logic runs the opposite way to everything else on this page: the best moment to do it is the moment it feels least urgent.

Egg freezing is an IVF cycle that stops after egg collection. Age at freezing drives everything that follows, because it fixes the quality of what is stored. Be clear-eyed about the chain between a frozen egg and a baby: eggs have to survive the thaw, then fertilise, then develop into a usable embryo, then implant, then result in a live birth. Each step loses some. That is why clinics talk about the number of mature eggs you want banked rather than a single cycle, why women in their early thirties often need one or two cycles and women in their late thirties often need more, and why "I froze eggs" is not the same sentence as "I have a baby in the freezer".

Embryo freezing fertilises the eggs first. Per embryo stored you know more, because an embryo that reached day five has already cleared hurdles an egg has not, but it requires sperm at the time of freezing and it ties the embryos to that partnership, which matters legally if the relationship ends.

Sperm freezing is the cheap, reliable one, and the one most often forgotten. It matters most before chemotherapy, radiotherapy, testicular surgery or gender-affirming hormone treatment, and before a vasectomy.

All three come with storage fees that run for years, and with national limits on how long storage may last. Ask about both before you start, not after.

The order, and how long it takes

The diagnostic workup is measured in weeks rather than months, though it can feel longer, because some tests have to happen on particular days of a cycle: the hormone panel early in the cycle, progesterone a week before the next period, the dye test after bleeding has stopped and before ovulation. Miss a window and you wait a month. Expect roughly four to eight weeks from first appointment to sitting down with a complete set of results.

An IVF cycle itself is shorter than most people imagine. From starting stimulation injections to an embryo transfer is roughly two to six weeks, depending on the protocol and on whether the embryos go back in the same cycle or are frozen for a later one. Add a couple of weeks before it for the pill or down-regulation, and two weeks after it before a pregnancy test means anything.

The part to plan for is that most people need more than one cycle. Cumulative live birth rates across several cycles are considerably better than the figure for any single one, and clinics that quote you a single-cycle number are not describing the journey most patients actually have. Budget, emotionally and financially, for two or three rather than one.

1. 1

   First appointment

   1 hour

   History for both partners, cycle details, previous pregnancies, surgery and medication. You leave with a list of tests rather than a diagnosis.

2. 2

   Testing

   2–6 weeks

   Semen analysis, AMH and antral follicle count, a hormone panel timed to the cycle, a tubal dye test and an ultrasound of the uterus. Cycle timing, not availability, sets the pace.

3. 3

   Results and plan

   1–2 weeks

   The consultation that matters. What the tests showed, which rung of the ladder it points to, and what the realistic odds are at your age. Ask for the live birth per cycle started figure here.

4. 4

   Stimulation

   8–14 days

   Daily injections with scans and blood tests every few days to track follicle growth, then a trigger injection roughly 36 hours before collection.

5. 5

   Egg collection

   20–30 minutes

   A day case under sedation, eggs retrieved through the vaginal wall with an ultrasound-guided needle. Sperm is produced or thawed the same day. Most people are home within hours and sore for a day or two.

6. 6

   Fertilisation and culture

   5–6 days

   Eggs fertilised conventionally or by ICSI, then grown in the laboratory. Numbers fall at every step, and the day-five count is usually well below the number of eggs collected. This is the week the phone calls come.

7. 7

   Transfer, or freeze and wait

   15 minutes, then 2 weeks

   One embryo placed in the uterus, spares frozen; or everything frozen for a transfer in a later cycle. Then roughly two weeks before a pregnancy test means anything.

When a cycle fails

Book a follow-up review and ask three specific things. How many eggs were mature, what happened between day three and day five in the lab, and what would change next time. A failed cycle that produces a better protocol is worth more than a vague reassurance.

What the success numbers mean

This is where the field misleads people, usually without technically lying.

A clinic can quote you a clinical pregnancy rate per transfer, and it will be the highest number available: it counts pregnancies rather than babies, and it only counts cycles that made it as far as a transfer, quietly excluding cycles cancelled before egg collection and cycles where nothing was worth transferring. The number that describes your actual odds is the live birth rate per cycle started. When someone quotes you a figure, ask which of those it is. If the answer is vague, treat the number as marketing.

Age is the dominant variable, and nothing else comes close. Per cycle started, live birth rates for women using their own eggs run roughly a third under 35, decline through the late thirties, and fall steeply after 40 into single figures by the early forties. Those are wide bands on purpose; published registry figures vary by country and by year, and any single clinic's numbers also reflect which patients it accepts. A clinic that turns down difficult cases will always look better than one that does not.

Two more things worth saying plainly. PGT-A, genetic screening of embryos before transfer, is contested: it can reduce the number of transfers needed in some groups, but good trials have not shown that it reliably produces more babies per cycle started, and in younger patients it may do harm by discarding embryos that would have worked. And most add-ons sold alongside IVF, endometrial scratch, assisted hatching, immune therapies, various supplements and infusions, do not have good evidence behind them. They do have prices. Ask what the evidence is and who paid for it.

What it actually costs

Quoted cycle prices are real, and almost always incomplete. In the US, self-pay IVF is typically quoted at roughly $12,000 to $20,000 a cycle; in the UK, private cycles are commonly quoted around £5,000 to £8,000; in much of Europe, Thailand and Australia, less again, though the comparison is only fair once you add travel and repeat visits.

What a quoted price usually excludes:

• Drugs. The biggest omission. Stimulation medication frequently adds several thousand dollars or a few thousand pounds, and the dose depends on your ovarian reserve, so the people who need the most are quoted the least accurately.
• ICSI, and sometimes the embryology beyond basic fertilisation. Often a separate line.
• Freezing and storage. Freezing spare embryos is usually extra, and storage is an annual fee that runs for as long as you keep them.
• Frozen embryo transfers. Each subsequent transfer from that batch is its own charge, with its own monitoring and drugs.
• Add-ons. Priced individually, added enthusiastically, evidenced thinly.
• Tests, consultations and monitoring scans, which may or may not be inside the package.

Ask every clinic for the all-in cost of getting from today to one live birth attempt including a frozen transfer, in writing. The ranking of clinics by price changes once you do.

Funding varies wildly: some countries fund several cycles through the public system, some fund none, and insurance coverage in the US depends on the state and the employer. Where you live may matter more to the bill than which clinic you choose.

How to use this site

Every guide, as it is published, will follow the same shape: who it is for, how it works, what the process is week by week, what the odds really are, the risks, the alternatives, the cost, and the questions to ask at your consultation. Once you have read one, you can read any of them fast.

Until then, this page is the overview, the about page explains who is writing and why, including the commercial interest I have and how I handle it, and the contact page is where questions and corrections go. Nothing here is medical advice. Your clinician has seen your results; I have not. Use this to ask them better questions.

Frequently asked questions

Do I need IVF, or should I just get tested first?

Test first, in almost every case. The workup takes weeks, costs a fraction of a cycle, and quite often points to something simpler than IVF, such as ovulation induction for PCOS or treating a correctable male factor. See what gets checked first.

What does a success rate of 40% actually mean?

Usually not what you think. It is often clinical pregnancy per transfer, which counts pregnancies rather than babies and ignores cycles that never reached transfer. Ask for live birth per cycle started, by age band. See what the success numbers mean.

How many cycles will I need?

More than one, for most people. Cumulative live birth rates across two or three cycles are meaningfully higher than for a single cycle, which is why budgeting for one is the most common financial mistake I see. See the order, and how long it takes.

Is egg freezing worth it?

It depends almost entirely on your age when you freeze, and on how many mature eggs you bank. Frozen eggs are insurance with an excess, not a guarantee: they have to survive the thaw, fertilise, become an embryo and implant. See freezing is a separate track.

Is this medical advice?

No. It is what a decade of coordinating patients teaches you, written down. Your clinic has your results and examines you; this site helps you ask them better questions.
