If, based on the history obtained during genetic counseling, family tree analysis, and the results of previous genetic tests conducted on the samples of affected individuals and other family members, the couple is diagnosed as being at risk of having a child with a genetic disorder. It is possible to carry out a genetic examination by the method of pre-implantation genetic diagnosis (PGD).
If we want to know about PGD in general, we must say that in this method, pregnancy occurs using the reproductive technology of ectopic or laboratory fertilization, and at a certain stage of the development of the embryos in the laboratory, sampling or biopsy of the embryos is done. One or more cells are separated from the embryos and genetic testing is done on these cells in terms of previously known mutations. In the next step, the embryos that have been diagnosed as healthy in terms of the investigated mutation are transferred to the mother's womb.
Benefits of PGD method
Due to the fact that diagnostic tests are performed before transferring the embryos to the mother's womb, if the mother becomes pregnant, there is a high probability that the pregnancy will occur with a healthy fetus, and the probability of needing to terminate the pregnancy is less.
Disadvantages of PGD method
Despite the high accuracy of this test, this accuracy rate is not 100%, and to ensure the health status of the fetus, it is still necessary to perform PND pregnancy diagnostic tests during the pregnancy period.
If the PGD method has been suggested to you, we would like to remind you that in each treatment cycle with the artificial insemination IVF method, in the most optimistic case, the possibility of your fertility is about 35-40%.
