Vitro Techniques Affect Baby Weight

KOMPAS.com - Mechanical engineering pregnancy through IVF or in vitro fertilization (IVF) can affect the baby's size at birth, according to a new study from Finland published the December issue of the journal Human Reproduction.

Research has shown that embryos cultured in a longer time (about 5-6 days) before being transferred to the womb of the mother tend to be born with a larger size for age gestasionalnya, compared to embryos cultured in a shorter time (only about 2-3 days). Embryos that the older cultures also tend to be born with a size no smaller than gestasionalnya age. Gestational age is a period which indicates how long the fetus in the womb.
According to previous research, the results of IVF babies at greater risk of preterm delivery and low weight. A number of factors related to pregnancy and IVF cause linkage. So far, the few studies that monitor the effect of the length of the embryos developed to the baby's weight at birth.
In this study, researchers from the University of Helsinki analyze the information of 1,079 babies (no twins) were born to mothers who underwent IVF techniques. The eggs of the mother is taken and fertilized in the laboratory, then do pengulturan for one to six days and then transferred to the womb of the mother. According to the American Pregnancy Association, the pengulturan occur for two to three days before being transferred to the womb.
From the number of babies who recorded with the pengulturan embryos for 2-3 days, the researchers saw a 10 percent who were born with less weight for age gestasionalnya, 10 percent are born with excess body weight, and 80 percent were born with normal weight, ie with an average weight of 7.7 pounds or about 3.4 kilograms. While with the pengulturan 5-6 days, then 19 percent are born with a greater weight, and 3 percent are born with less weight.
Babies born with a small risk of complications such as low blood sugar levels and neurological disability, and the risk of heart disease when adulthood. But being born bigger, does not mean there is no risk, they might have an increased risk of obesity.
The amount of the baby's body at birth is also a possibility could occur because of the magnitude of maternal body mass index before pregnancy. As for age, infertility mother, and did not affect fertilization methods.
