National patient survey results

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.

Trends in egg and sperm donation

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.

We also published some statistics on donation in 2011, looking at long-term trends between 1992 and 2010

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.
