In Nordic study, children born after frozen-thawed embryo transfer had higher cancer risk
Follow-up research is needed to confirm potential link between cancer and freeze-thaw strategy
Peer-Reviewed Publication
PLOS
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. Nona Sargisian of the University of Gothenburg, Sweden, and colleagues present these findings on September 1st in the open-access journal PLOS Medicine.
Assisted reproductive technology (ART) allows an embryo to be created from a human egg and sperm in a laboratory. A doctor may immediately transfer the embryo to the uterus, or, in a practice that is increasing worldwide, the embryo might be frozen and later thawed before implantation. Prior research suggests that children born after frozen-thawed transfer may have higher short-term risk of certain medical issues than children born after fresh embryo transfer. However, potential long-term medical risks have been less clear...
