129 questions people actually ask during IVF, each answered in one paragraph, grouped by stage of treatment. Every answer links to the page it came from, where the published sources are listed. This is educational information written by parents who have been through IVF, not medical advice, and it does not replace your own clinic.
What IVF is, how it works and how it differs from IUI and ICSI.
Most people find the injections cause mild stinging or bruising rather than significant pain. Egg retrieval is done under sedation or anaesthetic so you shouldn't feel it happening, though some cramping afterwards is common. Everyone's experience differs, so mention any concerns to your clinic.
From How does IVF work?
There's no fixed number that guarantees success, because not every egg fertilises and not every embryo develops well. Your clinic can talk you through what's typical for someone with your ovarian reserve, based on your AMH and antral follicle count.
From How does IVF work?
This depends mainly on sperm quality. ICSI, where a single sperm is injected into each egg, is often recommended when sperm count or movement is reduced, or after previous fertilisation problems. Your clinic will explain which applies to you.
From How does IVF work?
Some clinics offer natural or mild stimulation cycles with lower doses of medication or none at all, but these typically produce fewer eggs. Whether this suits you depends on your individual situation, so it's worth discussing directly with your clinic.
From How does IVF work?
Sometimes. Depending on the cause, options can include lifestyle changes, medical treatment, or surgery, and your clinic or a urologist can advise what's realistic for your specific result.
Not always. It depends on how low the count is and what else the semen analysis shows. Your clinic will advise based on the full picture, not one number alone.
No, azoospermia has different possible causes, some of which are treatable or allow surgical sperm retrieval, and some of which do not. This needs proper investigation by a specialist to know which applies.
Results can vary between samples, so clinics often want at least two tests, especially if the first result is borderline or unexpected, before basing a treatment plan on it.
Sperm quality can decline with age, though generally less sharply than the age-related change in egg quality. Ask your clinic about your own semen analysis results rather than relying on general age patterns.
Clinics often move from IUI to standard IVF or ICSI if IUI hasn't worked, but the exact recommendation depends on why IUI wasn't successful and what your test results show.
No. ICSI is a fertilisation method used inside an IVF cycle. You cannot have ICSI without also going through the IVF process of stimulation, egg collection and embryo transfer.
Generally yes, per cycle, though costs vary by clinic and you should get a specific quote for your circumstances.
IUI generally relies on at least one functioning fallopian tube, so it's usually not suitable if both tubes are blocked. Your clinic will check this with imaging before recommending a treatment path.
This can depend on age, diagnosis, how long you've been trying, or specific findings like blocked tubes or significant sperm issues. Ask your own clinic for their specific reasoning.
Every stage in order, from injections to transfer.
Expect several scan and blood test appointments during stimulation, usually every two to three days, plus the retrieval and transfer procedures themselves. The exact number depends on how your body responds and your clinic's monitoring approach.
Yes, cycles are sometimes paused or cancelled if the ovaries aren't responding as expected, or if there's a risk of ovarian hyperstimulation syndrome. Your clinic will explain the reasons and discuss options if this happens.
A fresh transfer happens in the same cycle as egg retrieval, while a frozen transfer uses an embryo frozen from a previous cycle, transferred later once your body has recovered or your womb lining is prepared. Your clinic will advise which suits your situation.
No, usually only one embryo is transferred at a time to reduce the risk of a multiple pregnancy. Any remaining suitable embryos can often be frozen for future use, though not all embryos survive to a stage where freezing is possible.
This varies enormously depending on whether you're being treated on the NHS or privately, and on how quickly your pre-treatment tests and screening come back. Ask your clinic for their typical timeframe when you have your first consultation.
The medical stages, stimulation, retrieval, culture and the wait to test, have biological timings that can't be rushed safely. What can sometimes be sped up is the administrative side, like booking tests promptly or choosing a clinic with shorter waiting lists.
Response to medication varies between individuals, and some protocols include an extra down-regulation phase before stimulation starts. A cycle can also be extended if monitoring shows it needs adjusting.
Not necessarily quicker overall, since it happens in a separate cycle from egg retrieval, but the transfer procedure itself and the two week wait afterwards follow a similar timeline to a fresh transfer.
Yes, many partners learn to give the injections during the teaching session and take this on through the cycle. It's entirely a personal choice whether you prefer to self-inject or have someone else do it.
Not usually because of the injections themselves, but ongoing bruising or soreness in one area can build up if you don't rotate sites. Switching between the tummy and thigh, and between left and right, can help.
Contact your clinic as soon as you realise. They can advise on next steps based on the specific medication and how late the dose was, rather than trying to work it out yourself.
Bloating is common but the extent varies a lot between individuals, partly linked to how many follicles are developing. Your clinic can tell you if what you're feeling seems within the expected range for your monitoring results.
You shouldn't feel pain during the procedure itself because of the sedation or anaesthetic. Afterwards, cramping similar to period pain and some bloating are common, usually easing within a day or two.
This depends on how your ovaries responded to stimulation, which your clinic will have been tracking through scans. There's no way to predict the exact number in advance, and it can differ from what the scans suggested.
Most clinics recommend resting for at least the remainder of the day and often the following day too, given the sedation and physical after-effects. Some people feel ready sooner, others need longer, so plan for flexibility if you can.
Occasionally, despite follicles appearing on scans, no eggs are retrieved. This is upsetting and uncommon, and your clinic will want to review what happened and discuss options for future cycles.
ICSI improves fertilisation rates specifically in cases of male factor infertility, but it doesn't necessarily improve overall pregnancy rates for everyone. Your clinic can explain whether it's likely to help in your particular situation.
This is distressing and uncommon but does happen. Your clinic will usually review the cycle with you afterwards to consider whether ICSI, different sperm preparation, or other adjustments might help in a future attempt.
Eggs with abnormal fertilisation, such as three pronuclei, aren't normally used for transfer because of the risk of chromosomal abnormalities. Clinics discard these rather than culture them further.
Clinics typically give updates on days 2 or 3, and again closer to transfer if you're going to day 5. Ask your clinic when to expect calls, since practice varies.
No. Grading describes appearance under a microscope and correlates loosely with the chance of implantation, but many other factors, including the womb lining and underlying chromosomal makeup, also matter and aren't fully visible through grading alone.
Clinics sometimes prioritise other factors, such as the embryo's stage of development matching the ideal transfer day, or freezing the highest graded embryo for a future cycle. It's worth asking your clinic directly about their reasoning for your particular embryos.
Not necessarily for everyone. Day 5 transfer allows more time to see which embryos develop well, but not all embryos survive to day 5 in the lab even if they might have implanted if transferred earlier. Your clinic will advise based on how many embryos you have.
Storage limits are set by law and clinic policy and can be extended in some circumstances. Ask your clinic about current storage limits and renewal processes, since this has changed in UK law in recent years.
Many people return to normal, non-strenuous activities the same or next day. Whether to take time off is a personal decision, often shaped by how physically or emotionally demanding your job is, rather than medical necessity.
Gentle activity like walking is generally fine, but your clinic may advise avoiding strenuous exercise, heavy lifting or high-impact activity during this time. Ask them specifically what they recommend for your situation.
Progesterone helps prepare and maintain the womb lining for implantation. In IVF cycles, natural progesterone production can be affected by the stimulation medication, which is why supplementation is commonly prescribed.
Bleeding during the wait doesn't automatically mean the cycle hasn't worked, some people who go on to get a positive test do bleed slightly beforehand. Contact your clinic if you're worried, but try to still test on the date given unless advised otherwise.
Some people notice mild cramping or spotting around the time implantation is thought to occur, but this isn't a reliable sign, and many people feel nothing at all despite a successful implantation.
Testing before hCG levels are reliably detectable increases the chance of a false negative, and if you had a trigger injection, testing too early can also cause a false positive from residual hormone. Waiting for the given date gives the most accurate result.
There's no good evidence that strict bed rest after transfer improves the chance of implantation. Most clinics now suggest resuming normal, gentle activity rather than staying still for extended periods.
A faint line still means hCG is present, but it's worth following up with the blood test your clinic will likely arrange to confirm the result and check the hormone level, since a line's faintness alone doesn't tell you much.
No. PGT is the general name for the family of tests. PGT-A is one specific type, screening for the wrong number of chromosomes. PGT-M and PGT-SR are different tests for different situations.
No test can guarantee that. PGT-A looks only at chromosome number in the cells sampled, and it does not test for every possible condition.
Not necessarily. It may help you avoid transferring an embryo unlikely to succeed, but it has not been shown to raise the overall live birth rate for everyone who uses it. Ask your clinic what the current evidence says for your situation.
This varies by area and by clinical indication. Ask your clinic or your NHS fertility service directly, since funding rules differ across the UK.
Clinics discuss this with you before testing starts. Options and storage rules should be explained by your clinic's embryology and counselling team.
The egg is handled with a very fine needle under controlled lab conditions. Not every injected egg will fertilise or develop normally, which is expected and monitored by the embryology team.
Where there is a sperm-related fertility problem, ICSI usually gives a better fertilisation rate. Where there is no such problem, the evidence for an overall benefit is limited.
Yes, this is one of the common reasons ICSI is chosen, since it needs only a single usable sperm per mature egg.
It adds a fee, but the amount varies by clinic. Ask for the exact figure in your treatment plan before you start.
This is a question for your clinic and for published research rather than something this page can answer with a figure. Ask your clinic what they can tell you based on current evidence.
What each medicine is for and where it sits in a cycle.
Storage instructions vary by device and by whether it has been opened, so follow the patient information leaflet in the box and your clinic's instructions rather than guessing.
From Gonal-F
Many people find them uncomfortable rather than painful, but this varies. Your clinic nurse can show you technique to make injections easier.
From Gonal-F
Contact your clinic as soon as you notice. Do not guess at what to do or double up, since timing during stimulation is monitored closely.
From Gonal-F
Gonal-F itself is not typically detected by home pregnancy tests, but ask your clinic about the correct timing for testing during your specific protocol.
From Gonal-F
Some presentations need reconstituting with a diluent before use. Follow the leaflet in the box and the technique your clinic nurse showed you.
From Menopur
This depends on the specific product and packaging, so check the patient information leaflet and your clinic's guidance.
From Menopur
Some people find Menopur stings more than other injections. Ask your clinic nurse about technique and timing, and mention persistent pain.
From Menopur
Contact your clinic rather than adjusting the timing yourself, since monitoring during stimulation depends on consistent dosing.
From Menopur
Storage varies by device and whether it is opened or unopened, so check the leaflet in the box and ask your clinic if unsure.
From Follistim
Some Follistim pen devices are used for multiple injections from one cartridge. Your clinic nurse will show you how the specific device you have been given works.
From Follistim
Contact your clinic to check rather than repeating the injection or guessing.
From Follistim
Some protocols combine it with other medicines. Only take what your clinic has specifically prescribed for you.
From Follistim
This depends on the pen or cartridge and whether it has been opened, so check the leaflet in the box and your clinic's instructions.
From Puregon
This depends on the prescribed dose and cartridge size. Your clinic nurse will explain how your specific pen is set up.
From Puregon
Mild soreness or bruising is common. Contact your clinic if you notice spreading redness, warmth, or other signs of infection.
From Puregon
Tell your clinic about anything else you take, including over the counter medicines and supplements.
From Puregon
Yes, the trigger is timed precisely by your clinic and egg retrieval is scheduled around it, so always confirm exact timing with your clinic rather than estimating.
From Ovitrelle
Because it contains hCG, it can cause a false positive on a home pregnancy test for a period afterwards. Ask your clinic when it is appropriate to test.
From Ovitrelle
Contact your clinic immediately, since the timing of egg retrieval depends on this injection.
From Ovitrelle
Check the patient information leaflet, as storage can depend on whether the pen has been used before.
From Ovitrelle
Egg retrieval is planned around a set number of hours after this injection, so confirm the exact time with your clinic and follow it precisely.
From Pregnyl
Some presentations require reconstituting with a diluent before injecting. Follow the leaflet in the box and your clinic nurse's instructions.
From Pregnyl
It contains hCG and can cause a false positive on a home test for some time afterwards, so ask your clinic when testing is appropriate.
From Pregnyl
Contact your clinic straight away, since this affects the timing of your retrieval.
From Pregnyl
Some presentations need reconstituting with the supplied diluent. Follow the leaflet in the box and your clinic nurse's guidance.
From Cetrotide
Contact your clinic as soon as possible rather than trying to correct it yourself, since timing during stimulation is closely monitored.
From Cetrotide
Storage instructions vary, so check the leaflet in the box for this specific product.
From Cetrotide
In an antagonist protocol it is added once follicles reach a certain stage, to prevent early ovulation at the point it becomes a risk. Your clinic will explain the exact plan for you.
From Cetrotide
It is commonly supplied as a pre-filled syringe, but confirm the exact device and technique with your clinic nurse.
From Orgalutran
Contact your clinic promptly rather than adjusting the schedule yourself.
From Orgalutran
Check the patient information leaflet for storage instructions specific to this product.
From Orgalutran
It is commonly used alongside an FSH medicine in an antagonist protocol, but only follow the combination your clinic has prescribed for you.
From Orgalutran
As a GnRH agonist, it can briefly increase hormone activity before suppressing it. Your clinic will explain what is expected in your specific protocol.
From Lupron (leuprorelin)
No, some clinics use it for down regulation and others use it as a trigger option, so follow your own clinic's explanation of why you have been prescribed it.
From Lupron (leuprorelin)
Check the patient information leaflet, as this varies by formulation.
From Lupron (leuprorelin)
Contact your clinic rather than trying to catch up or adjust the dose yourself.
From Lupron (leuprorelin)
Cyclogest and Utrogestan are commonly given vaginally, Utrogestan can also be taken orally, and Lubion is an injectable option. Your clinic chooses the form based on your protocol and preference.
Yes, it can cause bloating, breast tenderness and tiredness, which can feel like early pregnancy symptoms whether or not the cycle has worked. This is a recognised source of confusion during the two week wait.
Contact your clinic for guidance rather than doubling a later dose or skipping it.
This varies by clinic and circumstances, so follow your own clinic's plan rather than a general rule.
It helps prepare the uterine lining to a suitable thickness before an embryo is transferred, which your clinic checks by scan before proceeding.
Neither is universally better. Your clinic chooses the form based on your protocol, medical history and preference.
Contact your clinic rather than adjusting the schedule yourself, since consistent lining preparation matters for timing the transfer.
It can cause bloating, breast tenderness and mood changes, which can be confusing, so try not to read too much into these symptoms alone.
No, it is a tablet that works differently, and is typically used in milder stimulation or ovulation induction approaches rather than standard injectable IVF stimulation.
From Letrozole
Yes, your clinic will usually monitor the response with ultrasound scans, even though it is taken as a tablet.
From Letrozole
Contact your clinic for advice rather than taking an extra dose or skipping ahead.
From Letrozole
Some protocols combine letrozole with low doses of injectable medicines. Only follow the specific combination your clinic has prescribed.
From Letrozole
How to read the numbers without being sold to.
There is no single good figure that applies to everyone, because outcomes depend heavily on age and individual circumstances. Compare like with like using HFEA's published data rather than looking for one universal number.
This can happen if a clinic reports a favourable subgroup, a particular year, or a different definition of success than the standard one HFEA uses. Always check exactly what is being measured.
HFEA published data shows outcomes are strongly associated with the age of the eggs used, generally becoming less favourable with increasing age, though this varies between individuals.
Per cycle figures count from the start of stimulation, including cycles where no transfer happens at all. Per transfer figures only count cycles where an embryo was actually put back, so they are usually a higher number for the same group of patients.
Yes. Ask how their figures compare to the national data published by HFEA for people in a similar situation to yours, and ask what the figures mean in plain terms.
NHS funded treatment often has locally set age limits, but private clinics set their own upper limits, which vary. Ask your specific clinic what their policy is.
Sperm quality can also change with age, though the effect is generally less pronounced than the effect of age on eggs. Ask your clinic about semen analysis results specific to your case.
This is a personal decision that depends on your circumstances, and it's worth a dedicated consultation to discuss timing, cost and realistic expectations with a clinic.
AMH is a hormone level used to estimate ovarian reserve, meaning roughly how many eggs might be retrieved. A lower result does not mean treatment cannot work, but it may affect the approach your clinic recommends.
Outcomes using donor eggs depend mainly on the age of the person who provided the eggs, not the recipient's age, though the recipient's own health still matters for carrying the pregnancy.
This depends on your physical recovery, your clinic's protocol, and your own readiness. Ask your clinic directly what timeframe they recommend for your situation.
Not necessarily. IVF can be unsuccessful even when everything appears to have gone as expected at each stage, since implantation and early development involve factors that aren't fully understood or visible on scans.
Not automatically in every case. Ask specifically for a review appointment and ask what, if anything, they'd suggest investigating further before another attempt.
You would need a further full cycle including egg collection, or you might discuss other options with your clinic depending on your circumstances and test results.
Yes, this is common and reasonable. There's no requirement to start another cycle within any particular timeframe.
Choosing a clinic here or overseas.
Not necessarily. Price does not automatically track with outcomes, and outcomes depend heavily on the patients each clinic treats, not only on the clinic itself.
Yes, many people do. It brings different considerations around regulation, travel and communication, which is worth researching separately and thoroughly before committing.
Check the clinic's current status directly on HFEA's website, which lists licensed clinics and their inspection ratings.
Distance matters practically, since stimulation typically involves several early monitoring scans over a short period. Weigh convenience against other factors like outcome data and cost.
Yes. Many people have an initial consultation at more than one clinic before deciding, and there's no obligation to commit at a first appointment.
The part of IVF nobody prepares you for.
Yes. Relief and anxiety often sit together after a positive test, particularly in early pregnancy, and this is a common experience rather than a sign anything is wrong.
Counselling isn't only for people who feel they're struggling. Many people find it useful to have a neutral space to talk through decisions and feelings even when they feel broadly okay.
Ask them directly what kind of support they want, since this varies a lot between people and even between cycles for the same person. Attending appointments together where possible is often appreciated.
It's common for the pressure of treatment to show up in a relationship, especially around appointments and the two week wait. Talking openly about it, or seeking counselling together, can help.
That's entirely your choice. Many people manage IVF privately and rely on their clinic's support services or peer groups instead of people in their personal life.
