PARIS, June 15 (UPI) — Parents should be informed children born under assisted reproduction have a higher risk of congenital malformation, researchers in France advise.
Dr. Geraldine Viot, a clinical geneticist at the Maternite Port Royal Hospital in Paris, says most couples receiving reproduction help presently learn of congenital malformation risks only in response to questions.
Viot and colleagues conducted surveys at 33 French centers — registered to use technologies such as in vitro fertilization and ovarian stimulation — for births between 2003 to 2007, a total 15,162 children, and found the rate of major congenital malformation was 4.24 percent.
Major malformations — mostly heart and urogenital problems — were more common in boys, while benign tumors called angiomas occurred twice as frequently in girls than boys, the study said.
Viot estimates that some 200,000 children in France are born with congenital malformations and therefore it is a public health issue.
The findings were presented at the annual conference of the European Society of Human Genetics in Gothenburg, Sweden.
