This partnership provides an exciting opportunity for research that will benefit twin, triplet and higher-order multiple pregnancies.

Two studies (funded by the BMFMS programme) are already taking place at the centre.

The TTTS Registry, established in 2015, is being expanded, to give doctors more information for managing complicated pregnancies and there are a further nine new studies planned to begin between 2020 and 2023.

Performance of Antenatal Diagnostic Criteria of Twin-Anemia-Polycythemia Sequence

This study compares different sets of criteria to see how much they differ and is the first step towards finding a universal set of criteria which diagnoses TAPS cases appropriately.

TTTS/Multiple Pregnancy Registry

The Registry collects data on complicated multiple pregnancies, monochorionic twin pregnancies and uncomplicated triplet pregnancies. Read more about how this data helps us in research here.


ENCIRCLE is seeking to understand if we can reduce or prevent preterm birth using emergency cerclage. Read more about the ENCIRCLE study here.


TWINS-RF aims to find out how complications in a twin pregnancy with a shared placenta can affect babies’ neurodevelopment at one year of age. Read more about the TWINS-RF study here.

New research

Over the three years of the project pilot, the centre will commence nine new research studies. This research will look at how we can manage different types of pregnancies in order to make them safer for mother and babies.

These studies will help answer research questions raised by the Global Twins and Multiples Priority Setting Partnership and help to support the charity objectives to address inequalities in stillbirths, neonatal deaths and neonatal admissions.

More information on these studies will be available as they begin.
