N vitro fertilization (IVF) or better known as IVF has been
known since the 1980's. Each year, experts offer the latest techniques IVF
increasingly refined so that a greater chance of pregnancy.Dr.Jamie Grifo,
director of the NYU Fertility Center in New York, USA, explains, healthy
chromosomes and the selection of embryos is crucial for the success of
pregnancy and implantation into the uterus.
Traditional IVF is done by
stimulating the ovaries produce a number of eggs. Then the eggs will be
retrieved and fertilized by a sperm in the cup stained. Fertilized embryo was
developed in the laboratory setting. The doctor will take the healthiest
embryos, which is considered the most enduring, and then implanted into the womb.
The challenge is how to determine whether an embryo is the best? Several
embryos at once are avoided because it can lead to multiple pregnancies which
will ultimately increase complications. Quite often forced prematurely born twins.
Womans eggs age also affect pregnancy outcome. "Women aged 30 years had a
58 percent chance of pregnancy. At age 40, the odds dropped to 27
percent," said Grifo. He added that the older the age of the egg, the more
likely the occurrence of chromosomal disorders such as Down syndrome. Experts
are now trying a new approach that is doing the testing chromosomes in embryos
and cells that will develop into the placenta. The analysis is conducted
comprehensive embryos.
While waiting for the result, the embryos will be
frozen. Once the test results are known, will be selected embryos are
chromosomal normal. Then the doctor a healthy embryo. In this way, the mother
will only contain one fetus so that more healthy pregnancy to term delivery. If
the first doctor does the embryo implants in the second or third day, is now
performed on the fifth day of implantation. Additional time is used to select
embryos that are less good."With this approach, the chance of the mother
having a healthy baby is bigger," said Grifo who published his method in
the Journal of Assisted Reproduction and Genetics.
However, a new approach in
IVF technique makes the cost more expensive than the standard procedure.
According to Grifo, actually this method actually saves costs due to premature
births twins and can also reduce the risk of miscarriage. In Jakarta, some
fertility clinics also began to implement the development of the embryo outside
the womb for a longer period of time to acquire seed embryo Chances of
pregnancy even greater.
