LONDON,
England, July 24, 2007 (LifeSiteNews.com) - A recent British study shows that children
conceived by IVF have increased health problems and spend almost double the
time in hospital than naturally conceived children, the Daily Mail reports.
The 7-year
follow-up study, done in conjunction with Finnish studies, compared the
hospital costs of IVF-conceived children to naturally conceived children. It
examined 303 IVF-conceived children as well as 567 naturally-conceived
children, all of whom were born between the years 1990 and 1995. Prior studies
had reviewed the pregnancies of these children, their medical history and
neo-natal health as well as the case notes of their hospitalization.
Published
in the June 21, 2007 issue of Human Reproduction, the study showed that on
average, a child conceived through IVF was in hospital significantly more times
(1.76 vs. 1.07 times) than a naturally conceived child.
Dr.
Marjo-Riitta Jarvelin, professor at Imperial College London and one of the lead
researchers behind the report, told LifeSiteNews.com, "What we showed was
that actually there were certain disease groups which were more common among
those born after IVF." She added that this included "certain
infections, respiratory disease, and inflammatory disease," and noted that
there are some neurological disorders that are slightly more common as well.
The report
also notes that low birth weight and pre-term birth have been linked to IVF,
but these results may be influenced by the multiple births often resulting from
IVF. Nevertheless, single IVF children were also sicker than naturally
conceived children and spent more time in the hospital. During the 7-year
period, 61% of the singleton IVF children were hospitalized versus 46% of the
naturally conceived singletons.
Jarvelin
told LifeSiteNews.com that researchers don't know the reasons for the increased
amount of certain diseases among IVF children. Most of the children
born through IVF, however, are still healthy children, she said, "But
we have to be more cautious and parents should be carefully informed that there
might be some dangers that we might not know."
There are
dangers involved in the multiple implantations of embryos involved in IVF, but
this is not recommended anymore, said Jarvelin, because the fetuses are at
higher risk.
The IVF
mother is also at higher risk, not only from multiple implantations, but from
other clinical problems such as blood toxemia. There is an additional, very
rare condition seen among IVF women called Ovum Stimulation Syndrome, Jarvelin
stated, that is caused by the medication that is used to stimulate ovaries
during the IVF process. She stated that it can be "quite dangerous"
for the woman.
"What
this research really means," she concluded, "is that we need studies
following these children…It shows that we need follow-up and long-term studies
to see whether these people are really more healthy than naturally conceived
children."
These
newest findings are in accordance with past studies that have indicated that
children who are conceived through IVF have a higher risk of deformity and
over-all health problems. These problems include cerebral palsy, higher
mortality rates and "ambiguous genitalia".
