The Human Fertilisation and Embryology Authority has today decided to withdraw one of the enforcement powers underpinning its multiple births policy.
Fertility clinics have worked hard to rise to this public health challenge. By implementing and auditing their multiple births minimisation strategies clinics have decreased the UK IVF multiple birth rate each year since 2009, with the aim of reaching 10%
One of the most challenging decisions for an embryologist is deciding which embryo is the healthiest and will therefore give the best chance of a successful pregnancy. This is becoming more and more important especially if single embryo transfer is to work effectively. The most common method which can be used includes morphological evaluation where an embryo’s cell number, shape and degree of fragmentation is monitored.
Since the 2004 Fertility guideline, there have been advancements in the management of infertility and our understanding of the risks associated with fertility treatment. This knowledge underpins the new guideline, translating into better clinical care for patients.
Rachel Cutting has been awarded Healthcare Scientist of the Year for her work in developing national guidelines for the implementation of elective single embryo transfer.
Peter Braude, Emeritus Professor of Obstetrics and Gynaecology, comments on a recent study into multiple embryo transfer published in The Lancet.
‘One at a time’ is running a series of workshops for clinic staff in early 2012. The workshops are designed to help and support clinics in achieving the target maximum multiple birth rate, which is currently 15%.
New figures released today show that multiple births from IVF continue to fall. This follows the HFEA’s initiative to reduce multiple births – the single biggest risk of fertility treatment, and is supported by leading professional bodies in the sector.
In a recently published article in Human Reproduction, Swedish researchers have demonstrated that Sweden’s dramatic increase in single embryo transfer (SET) over the last 5 years, to 70% SET, has resulted not only in the expected decrease of multiple births and associated pre-maturity, but also in measurable, better health outcomes for IVF children and their mothers.
According to research published the journal Human Reproduction, twins born as a result of assisted reproductive technology (ART) are more likely to be admitted to neonatal intensive care and to be hospitalised in their first three years of life than spontaneously conceived twins.

Transferring single embryos to women’s wombs over several assisted reproduction cycles that use both fresh and frozen embryos is more effective and cheaper than transferring two or more embryos at one time, according to data from the world’s longest running series of patients who choose to have only one embryo implanted per cycle – elective single embryo transfer (eSET).

In February 2009, the HFEA's Interim Chief Executive, Alan Doran wrote to the NHS Directors of Public Health to outline the importance of ensuring that commissioning strategies are consistent with the HFEA's new multiple births policy.
Women are unaware of the increased health risks that are associated with multiple pregnancy, a new survey has found. The survey, which was conducted to support the One at a Time national strategy, was carried out amongst the general public to establish women’s attitudes to fertility treatment and multiple pregnancy.
Experts in fertility treatment have criticised new research which claims that women are being misled over the risks of having twins. The research undertaken by Dr Norbert Gleicher from the Centre of Human Reproduction in New York claims that giving birth to twins is no more risky than singleton births.
Doctors, embryologists, nurses, other clinical staff, patient groups and the Human Fertilisation and Embryology Authority (HFEA) have come together to launch a new national strategy to reduce the number of multiple pregnancies – the single biggest health risk of fertility treatment.
