Publication update: Fertility Trends
An interim report looking at treatments for 2020 using provisional HFEA data was published in May 2022 (Impact of COVID-19 on fertility treatment 2020) and we expect to publish the next Fertility Trends by summer 2023.
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. In 2021, we launched a new data submission system for clinics and migrated our data to a new database. This means we now need to upgrade our systems to enable us to make better use of our data for patients, clinicians and researchers – this work is due to be completed in winter 2022/23.
The HFEA will not be publishing our usual annual Register update – Fertility Trends – in 2022. The most recent analysis of success rates is Fertility Trends 2019 (published in May 2021).

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.

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.
