Success rates

Bourn Hall was the first IVF clinic in the world, set up 40 years ago to help people create their families, and we are incredibly proud of our IVF success rates.

Everyone we see is uniquely individual and your specific circumstances will affect the way in which you can start your family. That’s why we’d prefer to really get to know you before talking to you about your personal chances of fulfilling your dream of parenthood.

We know that understanding success rates can be difficult so to help you, we have explained some of the ways that success rates can be analysed and provided links to our regulatory body who provide independent information and advice.

The Human Fertilisation and Embryology Authority (HFEA) has guidelines for how results should be reported. The HFEA also reports on how a clinics’ results compare with the national averages – we’re proud that our success rates are above the national averages in many areas.

To book an initial consultation to discuss your individual options, just get in touch.

Clinical Pregnancy Rate

A common measure of success is a day 35 ultrasound scan which confirms a fetal heart and viable ongoing pregnancy, referred to as the clinical pregnancy rate. The table below shows the latest clinical pregnancy rates at each of our clinics per embryo transfer.

Live Birth Rates (LBR)

The HFEA advice is that clinics should also report on live birth rates (LBR), which is the birth event (whether it is one baby or twins it counts as a single delivery), and this is known as the live birth rate.

LBR per embryo transfer

The table below shows our latest statistics regarding our live birth rates per embryo transfer procedure.

LBR per embryo transferred

The latest HFEA guidance is to also present births per embryo transferred as it promotes embryo transfer practices that minimise the chances of twins, which carry health risks for the babies and the mother. This rate shows the number of births (counted as a single birth event i.e. twin births count as one live birth event) divided by the total number of embryos transferred.

The table below shows our latest statistics per embryo transferred for Cambridge and Norwich for 2019 (01/06/2018 to 31/05/2019) and Cambridge, Norwich and Wickford for 2020 (01/06/2019 to 31/05/2020). This is then compared with the most up to date national average published by the HFEA.

Understanding success rates – Independent guidance and advice

The Human Fertilisation and Embryology Authority (HFEA), which licenses fertility clinics in the UK, is our independent regulator.

The HFEA publishes live birth rates for all UK clinics and compares them with the national averages.  Live birth rates are now shown per embryo transfered and you can further analyse the data by age group, per cycle started, treatment type etc if you wish.
