Within the range of possible chromosomal abnormalities, some are less harmful to the embryo and allow it to implant. PGS means that embryos that will be the cause of situations of this kind can be ruled out.
By using PGS, we are able to avoid transferring embryos that will not lead to the birth of a healthy child since they will have been ruled out using the technique.
Adding a new analysis to the process could be indicative of an increase in the cost. However, an in-depth knowledge of the characteristics of each embryo means that embryos that would appear to be healthy but which, in fact, are not healthy from a genetics point of view are not frozen and stored.
Additionally, the cost of transferring embryos that will not lead to a pregnancy is avoided. Using PGS means that the uncertainty that patients go through is reduced. On the one hand, they have the guarantee of the health of their embryo and that the very latest technology has been used in order to ensure this. On the other, the risk of pregnancy loss is reduced and this reduces emotional stress, particularly in the case of patients who have already gone through this.
PGS means that the embryo needs to be biopsied in order to carry out the genetic test. However, significant progress to reduce the possible damaging effect of the biopsy has been made over the last few years. Carrying out the embryo biopsy on day 5 of development rather than on day 3 has been key to now being able to say that the embryo biopsy does not have a negative impact on embryo viability. In some cases, patients are at a high risk of having abnormal embryos. This is the case, for example, of mothers of an advanced age.
The eggs grow for five to seven days until reaching a size of hundreds of cells, called a blastocyst. The embryo is then frozen while doctors perform genetic testing on the extracted cells. Couples who opt for PGD should still conduct genetic tests during pregnancy, such as chorionic villus sampling CVS and amniocentesis. PGD increases the overall price tag by thousands of dollars, although Dr.
Flisser says the cost varies depending on the type of testing and the number of tests performed. Some insurance companies may cover the costs of PGD; ask your provider for more information. By Nicole Harris May 13, Save Pin FB More. Credit: Shutterstock. By Nicole Harris.
