What happens if IVF does not work?

The follow up review

Most clinics offer, and it's worth actively requesting if it isn't automatically booked, a review appointment after an unsuccessful cycle. This is a chance to go through the stimulation response, the number and quality of eggs and embryos, and the outcome of the transfer, in detail.

It's reasonable to ask direct questions in this appointment, including whether anything unusual happened at any stage and what, if anything, the clinic would suggest changing for a future attempt.

Do you have frozen embryos?

If embryos remain frozen from the same egg collection, a frozen embryo transfer is often the next step considered, since it avoids repeating stimulation and egg collection. This is usually a shorter and less medically involved process than starting from scratch.

If there are no remaining embryos

If no embryos remain, options generally include a further full cycle, sometimes with an adjusted stimulation protocol or additional testing first, or considering other paths depending on your circumstances and what the review appointment suggests.

Questions the review might raise

• Did stimulation produce the expected number of eggs, and if not, might a different protocol or dose be considered next time?
• Did fertilisation happen as expected, and if not, would ICSI be suggested for a future cycle?
• How did the embryos develop, and were any suitable for PGT-A testing if that's relevant to your case?
• Was the endometrium ready at the point of transfer, and is anything further worth investigating there?
• Is there anything in your test results that suggests further investigation before trying again?

A single unsuccessful cycle does not necessarily mean future cycles will have the same outcome, and it does not necessarily mean something is wrong. Cumulative live birth rate, the chance across a full course of treatment rather than one attempt, is generally the more useful figure to discuss with your clinic at this point.

Repeated implantation failure

If several good quality embryos have failed to implant across more than one cycle, some clinics investigate further, looking at things like the uterine cavity, immune factors, or embryo testing, though the evidence for some additional tests and treatments in this area is limited. Ask specifically what evidence supports anything suggested to you.

The emotional side of a failed cycle

A negative result or an early loss after IVF can be a significant grief, even if people around you don't fully understand what the cycle involved. Clinics are required to offer counselling, and it's worth using this alongside, not instead of, the clinical review.

Deciding whether to try again

Decisions about whether, when, and how to try again are personal and depend on emotional readiness, finances, age and clinical advice together. There is no fixed timescale that suits everyone, and taking a break between cycles is a reasonable choice if that's what you need.
