Preimplantation Genetic Diagnosis: Is PGD for You?

Genetic diseases that are passed on to the children stresses the parents. This is an understatement. With scientific innovations, prenatal testing has become an option so that even before the babies in the wombs of the mothers are born, the parents already know about the genetic diseases that their babies are likely to inherit. This prenatal procedure is called the chorionic villus testing or the CVS.

For such a time, CVS has become a wonderful option for parents because it has been through this process that they were able to provide early intervention against the genetic and chromosomal disease that their babies inherited from their parents. Now, though, the parents have an option not to bear unhealthy babies through another prenatal procedure.

The preimplantation genetic diagnosis is also called the PGD. PGD is a process which allows parents to make implantation decisions because through this, doctors can examine embryotic cell samples to check for genetic and chromosomal disorders.

What is PGD?

The process for PGD entails the removal of cells from a 3-day embryo for genetic and chromosomal tests. Although the doctors who are performing PGD may also focus on specific areas of the DNA if the parents have specific concerns regarding a particular health condition. When the results of the PGD becomes available, the doctors would then select the healthy embryos to be placed in the uterus.

Why PGD is used?

PGD is used for a variety of reasons. Doctors may recommend this procedure when either partner have known chromosomal abnormalities, or if the mother has s a history of repeated miscarriages. Aside from this, PGD may also be an option in instances when the male partner has low sperm production.

Risks of PGD

The PGD process is not harmful or hazardous to health, but there is a 1% chance of harm to the embryo. Of course, this depends on the skill and knowledge of the doctors. Unfortunately, PGD may also reduce an embryo’s ability to implant in the uterus, which is necessary for pregnancy.

Limitations of PGD

PGS cannot guarantee a successful pregnancy, neither can it guarantee a healthy infant. Moreover, the PGD process is not being overseen because it lacks a regulatory board. Meaning, PGD is essentially unmonitored; it is also not studied to a great extent.

PGD is a prenatal procedure that is invaluable to most couples who need it for medical purposes. However, if the reason for wanting to undergo this procedure is merely based on the choice of gender of a baby, then maybe you should think twice before deciding to go for this procedure.
