Our IVF Success Rates
We believe our holistic and personalised approach to fertility and IVF together with the exceptional team of doctors, fertility nurses, nutritionists, counsellors and hypnotherapists that are here to support you throughout your IVF treatment, have a positive impact on the success rates we achieve for our patients.
Our latest results for the period 1.1.20-31.12.21 show a Clinical Pregnancy Rate (CPR) of 42% for women under the age of 35 per fresh embryo transferred, using their own eggs. Our Live Birth results for the period 1.1.2018-31.12.2019 (latest HFEA data) for women under 35 is 41% per fresh embryo transferred.
Commenting on the results, Dr George Ndukwe, our Medical Director says “Some of the best IVF clinics in the UK are in London and I am thrilled that we continue to maintain our strong clinical pregnancy and live birth results per embryo transferred in women under 35 years. Particularly as we treat a lot of patients who have had several failed cycles, who are not expected to do well, statistically.”
All the embryology for our patients is carried out at CARE Fertility London, the HFEA licenced centre, where all our egg collections and embryo transfers also take place, carried out by our doctors. The Zita West Fertility Clinic is not an HFEA licenced clinic as we do not have an embryology laboratory on site.
Our results are validated by CARE Fertility London, which is regulated by the HFEA, who verify their data for accuracy.

Understanding Success Rates
It’s not always easy to understand what a clinic’s results mean. The best way to really understand your chances of successful treatment with us is to talk to one of our consultants or, alternatively, to our Clinic Director.
It’s important to be aware that success rates have limitations as the basis for comparison or personal choice. The HFEA publishes on its website the results of every licenced clinic in the UK. To understand fertility success rates and other factors that are important when choosing a fertility clinic, please refer to the HFEA website: www.hfea.gov.uk/choose-a-clinic/.
Clinical Pregnancy Rate per Embryo Transferred: This rate shows the number of clinical pregnancies (counted as pregnancy events ie a twin pregnancy is counted as two clinical pregnancies) divided by the total number of embryos transferred.
We present the Clinical Pregnancy Rate 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. However, this measure does not incorporate the outcomes of patients who do not reach embryo transfer stage.
Clinical Pregnancy Rate per Embryo Transfer: This rate shows the number of clinical pregnancies (counted as a single event ie a twin pregnancy counts as one pregnancy event) divided by the number of embryo transfer procedures.
Pregnancy rates at 44+ are extremely low (according to the HFEA and our own data).
