“Older mothers may benefit from IVF treatment’
Women who are after their forty, the mother to be may have much to gain from undergoing an IVF treatment. Researchers from the university of Adelaide have found evidence that the risk of birth defects in the baby are reduced by the treatment.
The researchers compared the data of close to 350,000 children born in the period from 1986 to 2002 in South Australia. Over 300,000 children were without medical interventions, begotten, 2.200 children after IVF treatment and 1,400 children after intracytoplasmic sperm injection (injecting a single sperm into an egg).
On that group, it was calculated that the number of birth defects in approximately 5.7 percent of the children appeared who were born without medical interventions. In children who after a course of IVF treatment were born was 7.1 percent and in children born after intracytoplasmic sperm injection (ICSI), 9.9 percent.
In mothers who are thirty years were at the birth of their child ran the risk of a congenital abnormality to 11.3 percent if the child, after a medical surgery was born. In mothers who forty were at the birth of their child took this risk rather: to 3.6 percent.
The researchers call the findings ‘remarkable’. “We know from previous studies that for births after a medical treatment, the chance of birth defects increases. We also know that the chance of birth defects increases as the mother gets older. We have now discovered that this, however, does not necessarily mean that the use of a medical intervention in older mothers, the chances of birth defects further increases.”
The scientists emphasize in the magazine Obstetrics & Gynaecology, it is important that more research is done into the effects of medical interventions in mothers.
