Success rates

Success rates

CREATE have spearheaded Mild and Natural IVF in the UK and we are very proud of the success rates we have achieved.

We understand how important success rates can be when choosing a fertility clinic so it’s vitally important these are as accurate as possible.

We understand how important success rates can be when choosing a fertility clinic so it’s vitally important these are as accurate as possible.

Your personal success

We strive to be open, transparent and honest about our results, for this reason we’ve included the latest verified data published by the Human Fertilisation and Embryology Authority (HFEA) so you can be confident in our figures.

The only true way to get a real understanding of your success rates is to have an Advanced Ultrasound Scan & Virtual Consultation where one of our experienced consultants will be able to discuss the likelihood of success specifically based on your situation, giving you a more accurate assessment of your chances using IVF treatment.

This individual success rate will give an estimation of your chances of success based on a number of factors including your reproductive history, age, egg reserve, previous treatment history and any potential male factor issues.

 

Your specific IVF success rate

It can often be very confusing trying to understand a clinics success rates, this is why it is important to remember that age alone cannot determine success, other things can also have an effect. You should consider the following:

  • The type of patients and any selection criteria
  • The type of treatment the clinic offers

There are a number of factors that affect success rates, we at CREATE judge success not simply by one number but by; improving health outcomes, lowering risk of complications and reducing treatment side-effects. We are specialists in using advanced ultrasound to maximise success and will be able to offer advice and recommendations based on our in-depth diagnosis. Your chances of success, health and safety are our priorities and all aspects will be discussed to allow you to make an informed decision.

Information on success rates can be of limited value when comparing centers and treatment types. For further information we have included definitions of each success rate measure in our FAQs section, we also have a blog on interpreting success rates, or you can visit the HFEA’s advice page on success rates.

 

How to understand IVF success rates

When looking at IVF success rates, please take care to look at exactly what is being measured.

Is the clinic:

  • Showing results for pregnancies or live births
  • Measuring success per cycle, per patient, per embryo transfer or per embryo transferred 
  • Displaying the number of cycles
  • Showing how many embryos were transferred

Factors such as these can have a huge impact on the ultimate meaning of the figures. Another thing to consider is which treatment type is being examined. Every patient is different and requires an individualised treatment plan.

The HFEA has strict guidelines on how success rates should be reported. They also report on whether a clinics’ results are below, consistent or above the national average. We treat many complex cases and always put the health and safety of our patients just as high as our drive for excellent success rates. We’re extremely proud to perform above the national average in many areas.

Mild Stimulation IVF success rates

Mild Stimulation IVF is tailored to a woman’s natural cycle, using a short 5-9 day course of lower dose stimulating drugs in order to achieve a mild response. The focus is on quality of eggs and embryos, not quantity.

  • Fewer side effects - Due to lower drug doses which achieve a mild response and working with your natural cycle rather than using downregulation
  • Healthier outcomes - We aim to achieve healthier outcomes for both mother and baby.
  • Safer - We have an unparalleled track-record of OHSS prevention
  • Shorter treatment duration - Approximately 2 weeks
  • Personalised treatment - We tailor our treatment plans to give you your best possible chance of success
 

Natural Cycle IVF success rates

CREATE Fertility has the most experience and expertise in Natural and Natural Modified IVF in the UK. We have pioneered new protocols and methods to advance Natural IVF and to increase its success rates. Natural & Natural Modified IVF success rates are combined. With Natural IVF and Natural Modified IVF, we are able to help women who have been turned away elsewhere or told that egg donation is their only option.

  • Own eggs - This treatment is particularly suitable for older women or those with a low ovarian reserve (low antral follicle count, low AMH and high FSH blood results)
  • Healthier outcomes - We aim to achieve healthier outcomes for both mother and baby.
  • Safer - We have an unparalleled track-record of OHSS prevention
 

Frozen Embryo Transfer (FET) success rates

Natural & Stimulated Cycles Combined

FET cycles can be used when a patient has embryos frozen from previous cycles of IVF. It is performed in a unstimulated cycle and involves careful monitoring and preparation of the lining of the uterus (endometrium), ready for the transfer of frozen embryos.

These are combined natural and stimulated cycles. It should be noted we have a very high number of embryos originating from natural cycles from women with low ovarian reserve in this data. It is not meaningful to compare these results with the national average because most clinics perform FETs with embryos obtained only from stimulated cycles. Clinics that specialise in treating low ovarian reserve patients can be seen to produce lower results. We are very proud of our FET success rates which are very good for this particular group of patients.

 

Frequently asked questions

What does per embryo transferred mean?

This is the number of pregnancies/babies born per actual number of embryos transferred. It therefore adjusts for multiple embryos being transferred.

What does per treatment cycle mean?

This is the number of pregnancies/babies born per number of cycles started. This includes cycles that do not reach embryo transfer stage.

What is a clinical pregnancy?

A clinical pregnancy is a pregnancy that is confirmed by ultrasound confirmation of a gestational sac or heartbeat.

What does live birth rate mean?

A live birth is the delivery of a baby. This is calculated by dividing the number of live births in a given year, by the number of embryo transfer procedures or treatment cycles in the same year. This is multiplied by 100 to give a percentage.

What is HFEA verified data?

The Human Fertilisation & Embryology Authority (HFEA) is the UK’s independent regulator of fertility treatment and research using human embryos. They offer impartial, accurate information about IVF, clinics and other fertility treatments. HFEA verified data has all been calculated in the same way. We always use the latest HFEA verified data so you can be confident in our figures.
