HFEA policy on multiple births

Following a public consultation in 2007, the Human Fertilisation and Embryology Authority (HFEA) launched their policy on minimising the risk of multiple births from IVF treatment in January 2009.

Key elements of the policy

• Overall aim to reduce the UK IVF multiple birth rate to 10% in stages over a period of years
• The HFEA will set a maximum multiple birth rate that clinics should not exceed, which will be lowered each year
• All centres will devise their own ‘multiple births minimisation strategy’ setting out how they will not exceed the maximum multiple birth rate
• The HFEA policy will form part of a wider national strategy to reduce the risk of multiple births from fertility treatment involving professional bodies, patient groups and NHS-funding bodies

What are centres required to do?

All IVF centres must have a multiple births minimisation strategy, that sets out how the centre:

• intends to reduce their multiple birth rate so it does not exceed the HFEA maximum multiple birth rate for that year
• identifies suitable cases for single embryo transfer at their clinic, using patient selection and embryo assessment criteria

Centres are required to regularly audit and evaluate the progress and effectiveness of their strategy. They must also log cases in which multiple embryos were transferred in patients who met the criteria in their strategy.

What is the maximum multiple birth rate?

2009 Year 1: Maximum 24%
The policy was introduced in January 2009. The HFEA set the Year 1 maximum multiple birth rate at 24%, the national average at the time.

This means that no more than 24% of a centre’s annual live birth rate should be multiple births. It includes all births from IVF, ICSI, and GIFT treatments, using fresh or frozen embryos from either the patient’s own eggs or donor eggs.

2010 Year 2: Maximum 20%
In December 2009 the HFEA evaluated the first year of the multiple births policy, by analysing the available 2009 pregnancy data along with feedback from patients and clinics.

On the basis of this, in January 2010 the Authority set 20% as the Year 2 maximum multiple birth rate. The Authority decided that 20% would maintain the momentum that centres built up in 2009, whilst allowing centres time to review and improve their strategies to lower their multiple rate further. 

The Year 2 maximum multiple birth rate came into force on 6 April 2010, and means that no more than 20% of a centre’s annual live birth rate from treatment started from this date should be multiples.

Monitoring and enforcing the policy

The HFEA is committed to supporting centres implement the policy and to help share best practice across the sector. We are continually monitoring clinics’ performance and the impact of the policy on multiple and overall pregnancy and birth rates.

We will support centres as they evaluate and improve the effectiveness of their multiple birth minimisation strategies. If centres are unable to do this, they will be asked, as a first step, to attend a management review meeting with HFEA staff to discuss recommended actions. This is in line with the HFEA’s overarching Compliance and Enforcement Policy.

Multiple births is a focus of inspection in the new compliance cycle.
