Success Rates

At Manchester Fertility our pregnancy and live birth rates for IVF and other treatments make us one of the most successful fertility clinics in the UK for all age groups and diagnosis.

We have a long-standing heritage in treating infertility and our continuous programme of investment ensures that as our patient, you benefit from the very latest proven treatment breakthroughs that science can offer, to help you have a baby.

These include EmbryoGlue, a special solution which helps your embryo to ‘stick’ to your uterus after transfer; EmbryScope time-lapse incubators for undisturbed embryo culture that give us detailed analysis of development so only the best embryos are chosen; and procedures such as Endometrial Scratching, performed just before IVF, to help embryos implant.

Over 5,000 babies have been born to date thanks to the expertise of our fertility specialists and the passion of our team.

Latest Results

Our pregnancy rates are confirmed and recorded by us only when a foetal heartbeat has been detected via our ultrasound team, this is referred to as a clinical pregnancy. The numbers below relate to confirmed clinical pregnancies only for patients aged under 38 years.  

HFEA IVF success rates

The Human Fertilisation and Embryology Authoity (HFEA) collect data about the treatments we carry out. As a HFEA-licensed clinic, we report all our figures to the HFEA for official recording. You can see our latest statistics here.

Understanding IVF and infertility treatment success rates

It’s extremely difficult to compare clinic success rates fairly. This is because success rates depend on the patients being treated and the reason for their infertility.

In addition, some clinics specialise in treating people with certain types of infertility or older women who are less likely to be successful, which will impact on their rate. That’s why we recommend you consider all the issues that matter to you – from opening hours to counselling provision – when choosing a clinic and not rely solely on the data. 

So here's why it’s important to be cautious when using success rates as a basis of comparison between fertility clinics:

Clinical pregnancy or positive pregnancy test? Some clinics use their biochemical pregnancy rates as an indication of success, but what this means is simply the numbers of positive pregnancy tests reported by patients, and not confirmed, clinical pregnancies when a foetal heartbeat is detected through ultrasound scan. We only publish data relating to our clinical pregnancies – not our patients who report positive pregnancy tests - as this can artificially increase success rates. Read our blog here about success rates.

IVF comparison tables: Be cautious of IVF success rate comparison tables. If a clinic chooses to rank itself against others, they will always ensure their data shows they are at the top, with no detailed explanation and no like for like comparison. They may use old data from other clinics, or only numbers which relate to a tiny portion of patients - something which HFEA advises against. Read our blog here about the use of success rate comparison tables.

Patient profiles: Patient profile differs greatly between clinics. Some may treat larger numbers of older women; or more difficult infertility cases; and this will be reflected in their success rates.

Single Embryo Transfer policy (SET): Some clinics may also carry out high numbers of IVF or infertility treatment cycles where more than one embryo is routinely transferred. The HFEA has recently removed the 10% multiple birth rate target as a condition of clinic license. What this means is that clinics are free to transfer two or three embryos during your treatment cycle, and so success rates may be higher for this reason. At Manchester Fertility we continue to follow the HFEA-advised Single Embryo Transfer policy – which is where only one embryo is transferred if you have a good prognosis. When looking at published success results, you should examine the ‘per embryo transfer’ figures for clinics, as this gives you the best indication regardless of how many embryos are transferred per cycle.

The HFEA has plenty of advice about interpreting success rates and using them as an indication of a clinic’s performance. You can also read our tips about choosing the right infertility clinic for you, so that you can make an informed choice.
