through certain techniques of infertility treatment are often designed
third birth defects than babies who have conceived without additional
help from technology, following a review of dozens of studies.But
the researchers, whose findings were in the journal Fertility and
Sterility published, not to determine why the associated treatment of
infertility associated with an increased risk of birth defects or if
the technology is still in charge Birth Defects More Common in IVF Babies: Study.
In-vitro fertilization (IVF) - in which the mother's egg is fertilized outside her body and then transferred to the parent company - was available for mothers in grass for more than three decades, numerous studies have analyzed the possible dangers of these techniques.
Hu Zhibin Nanjing Medical University and his colleagues gathered the results of 46 studies that compared the designed number of deformities in children by in vitro fertilization technique for children conceived normally.
Since more than 124,000 children born through IVF or use, in which a single sperm is injected directly into the egg ICSI, the risk of birth defects was 37 percent higher than for other children, they found.
"The children conceived by in vitro fertilization and / or ICSI show a significantly increased risk of birth defects, and there is no difference in risk between children conceived by in vitro fertilization and / or ICSI," they write.
According to the U.S. Centers for Disease Control, major malformations occur as deformity of a limb or organ, about three out of 100 babies born in the United States.
Meet an increase of 37 percent in four out of 100 babies would be price.
"(The report) confirms what most people have accepted anyway, so there is an increased risk of birth defects associated with assisted reproductive techniques," William Buckett, a professor at McGill University, said that was not included in the review n.
The increased risk of birth defects was apparent in a wide range of functions and systems of the body, including genitalia, skeletal, digestive and nervous system, the authors report.
The question of why most studies of birth defects found, developed more frequently in IVF babies, however, remains a question.
It `s possible to have the same reasons people to design problems and to seek fertility treatment can affect their risk of having a child with a birth defect.
It's also possible that IVF itself, the. Push and embryo manipulation, or drugs that are associated with artificial fertilization, could be involved
A third theory is that birth defects do not seem to be more common in babies carry through fertility treatments, there `re stronger than other babies follow, Buckett said.
"Couples who had babies born after IVF, is more closely monitored, and therefore can not detect subtle changes that otherwise could not be detected."
As for trying to reduce the risk of birth defects for parents with IVF, Hu said in an e-mail that "it is really too early to find ways to reduce risk, because explaining the reasons, the risks are largely unknown. "
