Success rates

At GCRM-Belfast, we have significant expertise in treating all forms of infertility and this is reflected in our excellent success, recently published by the HFEA.


As a Human Fertilisation & Embryology Authority (HFEA) licensed clinic, we report all our figures to them and the data below relates to confirmed clinical pregnancies, where a fetal heartbeat is seen on ultrasound scan
The HFEA collect and audit data from all UK clinics from the 1st of July to 30th June each year.  Our success rates across all ages are significantly higher than the UK national averages per cycle started and exceed those of other private & NHS providers here in Northern Ireland.

Understanding IVF/ICSI treatment success rates


It’s important to be cautious when using success rates as a basis of comparison between infertility clinics. The HFEA provides excellent advice on how to interpret success rates and use them as an indication of a clinic’s performance. You can follow their advice here.

PER CYCLE STARTED or PER EMBRYO TRANSFER? It is important to look for the  success rates per cycle started when researching clinics as these figures will include all patients who started treatment not only those who received an embryo transfer.

CLINICAL PREGNANCY OR POSITIVE PREGNANCY TEST? Some clinics use their positive pregnancy test rates as an indication of success rather than clinical pregnancies. Reporting results in this way gives a misleadingly high rate of success as not all pregnancies progress to the stage of seeing a fetal heartbeat. In keeping the HFEA regulations we only publish data relating to our clinical pregnancies.


IVF COMPARISON TABLES. When interpreting comparison data, it is important to ensure that there is a detailed explanation of the raw data and it uses like for like comparisons i.e.. the same time period, age group. The patient numbers must be large enough to give meaningful results.
