After a Failed IVF Cycle: What to Check Before Trying Again

A negative result after IVF is hard news, especially after weeks of injections, scans and waiting. It is also very common, and it does not mean the next cycle will fail too. What helps most is a calm, structured review of what happened in this cycle, so that the next attempt is planned on evidence rather than hope. This guide explains why cycles fail, what to look at with a specialist, and which popular "extras" the evidence does not support.

Short answer: Most IVF transfers do not lead to a birth: in the UK the average birth rate per embryo transferred was 30% in 2024, and it falls with age. After a failed cycle, review how your ovaries responded, how many embryos developed, embryo quality in relation to your age, your womb lining and any male factor. Be cautious with add-ons such as endometrial scratching, receptivity tests or immune treatments: the UK's NICE guideline advises against offering them. If egg quality is the main issue, donor eggs can change the picture.

How often does an IVF cycle fail?

More often than many people expect. The UK fertility regulator's latest figures show the birth rate for each embryo transferred using the patient's own eggs:

In other words, even in the best age group, most single transfers do not result in a baby. One failed cycle is usually a matter of chance rather than proof that something is wrong.

Why do IVF cycles fail?

There is often no single answer, but the main reasons fall into a few groups:

• The embryo: the most common reason. Many embryos carry chromosome errors that stop them implanting or developing, and this becomes more frequent as the woman gets older. Our guide to how age affects IVF explains why.
• The response to stimulation: too few eggs, too many, or eggs that were not mature.
• Fertilisation: sometimes few or no eggs fertilise, which can point to an egg or sperm problem.
• The womb: a thin lining, fibroids, polyps or scar tissue can make implantation less likely.
• The transfer itself: occasionally a difficult transfer plays a part.

What to review with a specialist

Ask your clinic for your full records: the stimulation chart, the egg collection and embryology report, and the transfer notes. With those, a specialist can go through these questions with you:

1. How did my ovaries respond? The number of eggs and how many were mature can suggest a different medication dose or protocol next time. Recent AMH and scan results help here.
2. How many eggs fertilised, and how many embryos reached day 5? If fertilisation was low, ICSI or a closer look at the sperm may be worth discussing.
3. What does embryo quality tell us, given my age? If the embryos were few or of poor quality and age is the main factor, it may be time to talk honestly about donor eggs. NICE recognises egg donation as effective in some cases of IVF failure.
4. Was my womb lining ready? NICE notes that a lining thinner than 5 mm is unlikely to result in a pregnancy. If the lining was thin, the preparation can be reviewed.
5. Is there anything in the womb that should be checked? A scan can show fibroids or polyps. NICE advises against routine hysteroscopy (a camera examination of the womb) unless an abnormality is suspected. Read more about fibroids and IVF.
6. Should the male partner be retested? A repeat semen analysis is simple and useful. See male fertility testing.
7. Is there anything we can change ourselves? NICE links smoking and a BMI of 30 or more with lower fertility in both women and men.

When is it "recurrent implantation failure"?

You may hear the term recurrent implantation failure (RIF). The European Society of Human Reproduction and Embryology (ESHRE) does not define it as a fixed number of failed transfers. Instead, it describes RIF as transfers of embryos considered viable failing often enough that the predicted chance of success had passed 60%. This depends on your age and the number and quality of embryos transferred.

For RIF, ESHRE recommends reviewing lifestyle, re-checking the womb lining and, for women with risk factors, testing for antiphospholipid syndrome (a blood-clotting condition). Other tests, such as a parental chromosome test, hysteroscopy, thyroid and progesterone checks, can be considered case by case.

Add-ons to be careful with

After a failed cycle, clinics often suggest extra procedures. Some are reasonable in specific cases; many are not supported by evidence. The UK regulator, the HFEA, rates add-ons on whether they improve the chance of having a baby, and the new NICE guideline (March 2026) makes clear recommendations on several of them:

This does not mean an add-on is never right for anyone. It means you should ask why it is being suggested for you, what it costs and what evidence supports it. These ratings come from UK bodies; clinics abroad, including in Cyprus, are not regulated by the HFEA, so it is worth asking any clinic the same questions. Our guide to genetic testing explains when PGT can be useful, for example for known genetic conditions.

NHS cycles after a failed attempt

Under the NICE guideline published in March 2026, women under 40 who meet the criteria should be offered 3 full NHS cycles, with up to 3 further cycles to be considered after discussion. Women aged 40 or 41 who have not had IVF before should be offered 1 full cycle. Self-funded cycles count towards the total, and local NHS boards decide what is funded in practice, so check with your GP or clinic.

Is it time for a second opinion?

If you have had more than one unsuccessful transfer, a fresh look at your records can be worthwhile, whether in the UK or abroad. Patients come to North Cyprus after failed cycles for a second opinion, for donor egg treatment, or because of waiting times and cost. Our guide to IVF in North and South Cyprus explains the differences, and our guide to embryo donation covers an option when both eggs and sperm are a factor.

You can send your previous treatment records and recent results through our medical assessment form. A specialist at one of our partner clinics will review them free of charge and tell you honestly what might be done differently. If you do not have recent results, see which tests to do in the UK.

Looking after yourself

A failed cycle can bring grief, anger and exhaustion, for both partners. NICE recommends that counselling is offered before, during and after treatment, whatever the outcome. In the UK, you can find accredited fertility counsellors through the British Infertility Counselling Association (BICA), and peer support through organisations such as Fertility Action and Fertility Friends. If you are also coping with pregnancy loss, see our article on IVF after recurrent miscarriage, and our emotional support page.

Frequently asked questions

How many failed cycles before we should change approach?

There is no fixed number. It depends on your age, how many good-quality embryos were transferred and what the records show. A review after each unsuccessful cycle is sensible; after two or three, a more detailed look at the whole picture is worthwhile.

Should I have PGT-A next time?

It depends on your situation. NICE advises against offering it just to improve live birth rates, and the HFEA rates it red for that purpose, but it may reduce the chance of miscarriage. ESHRE says it can be considered in recurrent implantation failure. Discuss it with a specialist who knows your history.

Will an endometrial scratch help?

The current evidence does not support it for most patients, and NICE advises against offering it.

Is it worth moving to donor eggs?

If age and egg quality are the main reasons for failure, donor eggs can significantly improve the chances, because success then depends largely on the donor's age. It is a big decision, and counselling is recommended before you make it.
