What is PGD/PGS?
Preimplantation Genetic Diagnosis (PGD) is a method which allows to eliminate the risk of passing on genetic disorders to a child before the woman gets pregnant. By examining the embryo cells, physicians are able to determine whether it has any DNA defects. For some patients it is the only possibility for having healthy offspring. Thanks to preimplantation genetic screening within in vitro program couples, who are concerned with their children’s health, can gain peace of mind. In the course of in vitro fertilization procedure, embryos are tested for genetic disorders and only those without any defects are transferred into the uterus. The performance of PGS diagnosis provides many couples with the chance of having a healthy offspring.
IVF program may fail due to abnormal implantation of the embryo in the uterus. The reason for this may be the occurrence of chromosomal aneuploidy (smaller or larger than the proper number of chromosomes of genetic material). Implantation of the embryo with aneuploidy may lead to the birth of a sick child e.g. with Down, Patau, Klinefelter, Edwards, Turner syndrome – however, the majority of pregnancies in such a case ends in miscarriage.
Performance of PGD testing allows to limit the risk of unsuccessful IVF program and to increase the chances of healthy pregnancy. INVICTA has the most extensive expertise in Poland as regards the performance of PGD. Every test is performed by at least two certified embryologists – thus the result is confirmed twice. Owing to the use of the latest generation techniques, at INVICTA Clinic PGD is performed with a “fresh cycle”, so it is not necessary to freeze the genetic material.
