Success rates

The first question most people ask when choosing a fertility clinic is, “what are their success rates?”


However, this isn’t a straightforward question to answer. Success rates can be presented in many different ways. Traditionally, the HFEA has used “live births per cycle started” to represent success rates. However, this does not take into account that some women may not complete their cycle of IVF – their cycle may be cancelled before they have an embryo transferred.


We feel that a more meaningful way to present success rates is by using “clinical pregnancy” or “live birth per embryo transferred”, or even “implantation rate”, which is the number of embryos that implant as a proportion of embryos that are transferred. At Jessop Fertility we are passionate about treating you safely, which means doing our best to provide you with a single, healthy pregnancy. We can do this best by transferring your embryos One At A Time, if it is appropriate - in 2016 over a third of our patients chose to have a single embryo transferred.


We are proud to present our latest clinical pregnancy results below. These results take account of ALL our patients who had IVF/ICSI from March to December 2016, including those who are older, who have a poor chance of pregnancy or who have had many unsuccessful attempts at IVF. Also – we don’t just perform IVF at Jessop Fertility. Many of our patients have intrauterine insemination as a first course of treatment. Not suitable for all patients, this is safer and cheaper than IVF, and many of our patients will become pregnant using IUI rather than proceeding straight to IVF.

  • Clinical pregnancy rate per embryo transfer = 37.2%. In other words, if patients have an embryo transferred at Jessop Fertility then they have nearly a 40% chance of getting pregnant. Please be aware though that this is dependent on many factors, especially female age. Older women may not have such a good chance, but younger women may do better.

  • Implantation rate per embryo transfer = 31.6%. This means that approximately 1 in every 3 embryos that we transfer does implant into the lining of the womb.

  • Cleavage rate = 95.5%. Because we use the best in human IVF culture media and cutting edge laboratory equipment, every egg that fertilises at Jessop Fertility has over a 95% chance of developing into an embryo.


At Jessop Fertility we are always striving to improve outcomes for all our patients. We provide a full service – from initial fertility investigations, through treatment, early pregnancy and beyond. Please contact us if you would like more information.
