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).

This report provides key information about the number and type of people newly registering as sperm and egg donors in the UK. It also gives information on trends in using donated sperm and eggs in fertility treatment, including how many treatments have been carried out and the demographics of patients.

This report complements our flagship annual publication, Fertility treatment: trends and figures, which provides key information about the number and type of fertility treatments that have been carried out across the UK and how many of these have led to a birth.

The national patient survey (released December 2018)

In September and October 2018 in partnership with YouGov we carried out the country's first ever national fertility patient survey, which invited people who had recently had fertility treatment and their partners to share their views on their treatment, covering every stage of their treatment.

In our report 'Pilot national fertility patient survey' you can read detailed analysis of the responses that we received from over 1000 fertility patients and their partners.

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.

Improving outcomes for fertility patients: multiple births

A multiple birth (twins, triplets or more) is the single biggest health risk associated with fertility treatment. Find out more about the risks of multiple births.

We've worked with the sector to reduce the proportion of multiple births and this report summarises our achievements to date.

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.
