Reducing the risk of complications associated with multiple pregnancy
Multiple births following in-vitro fertilisation (IVF) treatment leads to serious health risks in the mother and offspring. It is caused by placing multiple embryos within the uterus. However concerns about reduced success rates had deterred patients and practitioners from transplanting a single embryo.
A programme of research led from the University of Aberdeen on single embryo transfer in IVF established that a policy of placing one embryo at a time minimises the risk of twins without compromising live birth rates. This work has received international media coverage, influenced clinical guidance and resulted in an increased uptake of single embryo transfer in the United Kingdom and beyond.
