Potential link between Assisted Reproduction Technologies and Leukaemia, new research suggests

The HFEA responds to new research showing potential link between Assisted Reproduction Technologies and leukaemia.

A new study of more than 8 million French children suggests the possibility that children born as a result of assisted reproduction may have a higher risk of Leukaemia than those conceived naturally.

The paper, funded by the French National Agency for Medicines and Health Products Safety, used data from the French Mother-Child register between 2010 and 2021 to analyse and compare the odds of being diagnosed with cancer depending on how they were conceived (naturally, fresh embryo transfer, frozen embryo transfer or artificial insemination).

Rachel Cutting, HFEA Director of Compliance and Information, said:

“HFEA data shows that over 390,000 children were born as a result of fertility treatment in the UK between 1991 and 2021. This study is reassuring as the results show that the risk of Leukaemia for children born after assisted reproduction did not differ significantly from that of children conceived naturally.

“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”
