IVF has not worked more than once: what should be reviewed before trying again?
When IVF has not worked more than once, the next step is a careful review, not simply a repeat. The doctor looks back at each cycle: how the ovaries responded, the eggs, sperm and embryos, the womb lining and the transfer. Often something can be changed. Taking time to understand, and to recover, is part of treatment.

In this video, Dr Mayur Pai talks through how he approaches couples whose IVF has not worked more than once: what is worth reviewing, and what may be looked at or changed before the next cycle is planned. Every couple is assessed individually. This guide explains the thinking behind that review.
Where did the cycle stop?
IVF can stop at different points, and each one points the review in a different direction. So the first question is where your cycles stopped:
- Fewer eggs than expected, or eggs that were not mature.
- Eggs that did not fertilise well, or embryos that stopped growing in the laboratory.
- Good embryos that did not implant after transfer.
- A pregnancy that began but was lost early.
The last two situations have their own set of wider tests, including the womb cavity, thyroid, blood clotting, immune and genetic checks. These are explained in our guide to recurrent miscarriage and implantation failure. This article focuses on reviewing the IVF cycles themselves.
Why bring every record?
A review is only as good as the information behind it. Bring everything you have from each cycle: the medicines used, the scan findings, the number of eggs collected, how many fertilised, how the embryos developed and on which day they were transferred or frozen, the transfer notes and the pregnancy test results. If earlier cycles were done at another centre, ask them for a copy of these records. Small details, such as the day of transfer or how the lining looked, often matter.
How did the ovaries respond?
If very few eggs were collected, the stimulation plan may need to change: a different type of protocol, a different combination of medicines, or a different timing of the trigger. When the egg reserve is low, it can make sense to collect and freeze embryos over more than one cycle before transferring; our guide to low AMH explains why.
If the ovaries over-responded, producing a large number of eggs and a risk of complications, the next plan is made gentler, and the embryos may be frozen for a later, calmer transfer.
What about the eggs, sperm and embryos?
Egg quality depends mostly on age, and no test can check every egg. But the way the eggs behaved in the laboratory, how many matured, fertilised and kept growing, gives useful clues.
The sperm side deserves a fresh look too. A repeat semen analysis, and in selected cases further sperm tests, can show whether a male factor was underestimated. If fertilisation was low in a conventional IVF cycle, ICSI, where a single sperm is placed into each egg, may be advised next time. Treatable causes in the husband, and habits such as smoking, heat exposure and extra weight, should be addressed; see our guide to male infertility.
Wherever possible, we grow embryos to the day-five blastocyst stage. Watching them develop for longer helps the embryologist choose the strongest embryo for transfer, and it also tells us more about how the embryos behave.
What about the womb, the lining and the transfer?
A few problems are especially relevant after failed transfers. A blocked tube swollen with fluid can leak that fluid into the womb and make implantation harder; dealing with it by laparoscopy before the next transfer is a recognised step. Adenomyosis and endometriosis are looked for, and a camera test of the womb, called hysteroscopy, may be advised if the cavity needs a direct look.
The lining itself is reviewed: how thick it was, how it looked, and whether the timing of the transfer matched it. Sometimes it is wiser to freeze all the embryos and transfer later in a carefully prepared cycle, when the body is no longer recovering from stimulation; see frozen embryo transfer explained. Even the transfer is reviewed, including whether it was easy or difficult, so that the next one can be planned smoothly.
What can change next time?
After the review, the next plan might include one or more of these:
- a different stimulation plan, suited to how your ovaries actually responded
- ICSI, if fertilisation was the problem
- growing embryos to the blastocyst stage before choosing
- treating a problem in the womb, a tube or the lining before the next transfer
- freezing the embryos and transferring in a separate, prepared cycle
- correcting health factors in either partner, such as thyroid, sugar, weight or smoking
Sometimes the review finds no clear cause. That is hard to hear, but it does not mean nothing can be done. It means the next attempt is planned with the most favourable conditions possible, together with an honest discussion of your chances.
How can we look after ourselves?
Repeated failed cycles are painful. Grief, anger, guilt and exhaustion are all normal, and they can strain a marriage and family relationships. Please do not rush straight into the next cycle while the disappointment is fresh. A pause, usually of at least one full menstrual cycle, gives the body time to settle and gives you time to think.
Decide together how you want to go forward, including how many more attempts you feel ready for, physically, emotionally and financially. Tell the doctor what you are feeling, not only what you want to ask about the medical plan. We will not promise a result. What we will give you is a careful review and an honest answer about whether, and how, to try again.
Where treatment happens
This guide is by Dr Mayur Pai, MBBS, MS (Obstetrics & Gynaecology), a fertility and laparoscopy specialist. Pai Hospital in Goa has its own operating theatre and its own IVF laboratory, so laparoscopy and hysteroscopy, the laboratory work and the embryo transfer are handled by one team, with your full history in front of us.

Your questions
Why did IVF fail when our embryos looked good?
An embryo that looks good under the microscope can still carry a chromosome problem that cannot be seen, and implantation also depends on the lining, the timing and the transfer. That is why a failed transfer of good embryos is reviewed carefully, not simply repeated.
Should we start the next IVF cycle straight away?
It is usually wiser to wait at least one full menstrual cycle. The pause gives time to review what happened, to do any tests or treatment that are needed, and to recover emotionally before trying again.
Will changing the IVF protocol help?
Sometimes. If the ovaries responded too little or too much, a different stimulation plan, different medicines or a different trigger timing can help the next cycle. Whether a change makes sense depends on what your records show.
Can we use our frozen embryos for the next attempt?
Often, yes. Frozen embryos can be transferred in a later, prepared cycle without repeating the injections and egg collection. The doctor may first advise tests or treatment for the womb or the lining.
How many IVF attempts should we make?
There is no fixed number. It depends on the wife's age, the egg reserve, what the earlier cycles showed and what you feel ready for. After each review, the doctor gives you an honest view of whether another attempt is reasonable.
