An unsuccessful IVF cycle is disappointing, and it's important to acknowledge how difficult this experience is. But a failed cycle doesn't mean IVF will never work, many couples succeed on subsequent attempts. Each cycle provides valuable information that your specialist can use to optimise future treatment.
This page outlines what typically happens after an unsuccessful cycle, what your specialist looks for, and what options are available moving forward.
The Post-Cycle Review
After an unsuccessful cycle, your specialist will schedule a review appointment to discuss what happened and plan next steps. This review typically examines:
Ovarian Response
How many eggs were collected, whether the response was adequate, and whether medication adjustments could improve egg numbers in future cycles.
Fertilisation and Embryo Quality
How many eggs fertilised normally, how embryos developed, and whether embryo quality was a factor. This information guides decisions about laboratory techniques for future cycles.
Transfer and Implantation
Whether the embryo transfer was straightforward, endometrial thickness and appearance, and whether additional testing like an endometrial receptivity analysis (ERA) might help.
Overall Assessment
Your specialist brings together all the data from the cycle to create an adjusted plan. Sometimes the best approach is simply to try again with the same protocol; other times, specific changes are recommended.
Why IVF Cycles Don't Always Succeed
- Embryo chromosomal issues, The most common reason. Even healthy-looking embryos can carry chromosomal abnormalities that prevent implantation or lead to early loss.
- Implantation failure, Sometimes the embryo simply doesn't implant in the uterine lining, even when both appear healthy. The reasons aren't always identifiable.
- Poor ovarian response, Too few eggs collected means fewer embryos and lower chances of finding one that's chromosomally normal.
- Egg or sperm quality, Quality can vary between cycles and may be affected by age, health, and lifestyle factors.
- Uterine factors, Less common, but conditions like fibroids, polyps, or an unusually shaped uterus can occasionally affect implantation.
What Can Be Changed for Next Time?
Based on the review, your specialist may suggest one or more of the following adjustments:
- 1Different stimulation protocol, higher or lower medication doses, different combinations
- 2Modified trigger, changing the medication used to trigger egg maturation
- 3ICSI, if not used previously, or different laboratory approaches
- 4Preimplantation genetic testing (PGT), to select chromosomally normal embryos
- 5Frozen embryo transfer, sometimes separating the stimulation and transfer cycles improves outcomes
- 6Endometrial receptivity testing, to ensure optimal transfer timing
- 7Lifestyle modifications, optimising weight, reducing stress, improving nutrition
- 8Additional investigations, checking for conditions that may affect implantation
Alternative Paths to Parenthood
If multiple IVF cycles haven't been successful, there are other paths to consider:
- Donor eggs, using eggs from a younger donor, significantly improving success rates for women with poor egg quality
- Donor sperm, when male factor infertility is significant
- Donor embryos, using embryos donated by other couples
- Surrogacy, when carrying a pregnancy is not possible
- Adoption, building a family through adoption
These are deeply personal decisions. Dr Priya can discuss all options with compassion and without judgement, helping you understand what each involves.
