All HFEA licensed clinics are required by law to provide us with their fertility treatment and outcomes data. We store this in our Register, thought to be the largest database of fertility treatment in the world. Due to the pressures of COVID-19 on clinics and a large-scale data migration project for our data register, treatments and pregnancies from 2020-2021 and birth outcomes from 2019-2021 remain unvalidated. Data validation involves quality checking data submitted from licensed clinics across the UK to verify treatment, pregnancy and birth outcome data is correctly recorded on our data register. Data validation is expected to be completed in winter 2023/24.
The HFEA published our annual Register update – Fertility treatment: trends and figures – with preliminary data in June 2023. The data in this report will be updated following data validation.
Egg freezing in fertility treatment (released September 2018)
Our egg freezing report covers the trends and figures relating to egg freezing and the use of thawed eggs in fertility treatment from 2010 to 2016.
When looking at success rates for frozen eggs, numbers tend to be quite low. The technology for egg freezing has also improved over the years which means older data isn’t comparable to current success rates. We advise patients to look at success rates for fresh IVF cycles with patients using their own eggs in their age band. We consider these rates to be more reliable as there are much higher numbers of fresh embryo transfers each year compared to egg freezing. This information can be found in Choose a Fertility Clinic and in our Fertility Trends report.
Adverse incidents in fertility clinics: lessons to learn
The vast majority of fertility treatments are carried out without any problems occurring but, as in any clinical setting, mistakes can happen. Most people understand there are risks associated with any kind of healthcare, but they also rightly expect healthcare professionals to learn from those mistakes.
This annual report provides details of clinic incidents, allowing clinics to learn from each other and improve patient care.
