IVF could double risk of 'Cerebral Palsy'

IVF could double the risk of cerebral palsy, according to a study of more than 90,000 children.
Several studies have shown that rates of the neurological condition, which can result in speech problems, muscular stiffness and curvature of the spine, are higher in couples who have undergone in vitro fertilisation (IVF).

But this is the first to suggest that the process of IVF itself could increase the risk, rather than it being a consequence of the parents' impaired fertility

Researchers at the University of Aarhus in Denmark found that babies born by IVF were more than twice as likely to have cerebral palsy as those conceived naturally.

The result held up even after adjusting for factors like the age of the mother, if she smoked, and whether the baby was premature or a twin.

Dr Jin Lieang Zhu, an epidemiologist, and his team concluded that IVF was probably the underlying cause by looking at how rates of cerebral palsy changed depending on how long it took the mother to conceive naturally. This is considered a good measure of underlying fertility.

They found no statistically significant difference in rates between those whose mothers took less than two months to conceive, and those who took more than a year.

However, there was a much bigger difference between those who took over a year to conceive and those who only got pregnant thanks to IVF.

IVF pregnant women more at risk of death

Researchers believe the increased threat may come from the body rejecting donated eggs or underlying health problems that may come to the fore during artificial conception.
They want increased vigilance so that the exact nature of the risk can be calculated.

"Women should be counselled and made aware of the risks they are taking and deaths should be properly reported," Professor Didi Braat at Radboud University in the Netherlands told the Sunday Times.

Prof Braat looked at the deaths between 1984 and 2008 in the Netherlands but believes they will apply to any developed country.
