The HFEA responds to new research showing link between frozen-thawed embryos and cancer
A new study of more than 8 million children in Nordic countries suggests the possibility that children born after use of a fertility procedure known as frozen-thawed embryo transfer may have a higher risk of cancer than children born through other means.
The paper, produced by researchers at the University of Gothenburg, Sweden, has been published in the open-access journal PLOS Medicine. It analyses medical data from children in Denmark, Finland, Norway, and Sweden.
In response to the paper, Rachel Cutting, Director of Compliance and Information, Human Fertilisation & Embryology Authority (HFEA), said:
“Our latest data shows there were 25,000 frozen embryo transfers in a year in the UK. These findings should be interpreted with caution, as the number of children born after frozen-thawed embryo transfer in this study, who later developed cancer, was very low; 30.1 in 100,000 births.
“Health outcomes in children conceived using Assisted Reproductive Technology is a high priority for the HFEA and we provide high-quality information for patients and professionals using the new and emerging research we monitor. Anyone considering fertility treatment can access this, and other impartial information on fertility treatments and UK licenced clinics at www.hfea.gov.uk.”
