Genetic Examination and IVF
Genetic Examination and IVF; Thanks to today’s technologies, it has become possible to examine the problems that may occur before pregnancy and after birth and to take the necessary precautions regarding the health of the baby with genetic examinations. These genetic examination methods are often recommended to couples who face problems such as repeated pregnancy loss, failure to achieve a healthy pregnancy despite multiple attempts. Genetic examination, which enables to learn from which gene the problem is caused, is the first step to eliminate the problems in order to have a baby.
In the IVF treatment process, it is possible to scan the problematic genes and place healthy embryos in the uterus. Genetic examination is a frequently used method to reveal the risks that may occur in advance and to take the necessary precautions to have a healthy baby. For the details of genetic examination before IVF treatment, just continue reading our article.
How is the genetic examination carried out?
The genetic examination begins by taking a biopsy sample from the embryo. This sample helps to determine the content of the embryo’s DNA. As a result of the examination in the laboratory, embryos containing abnormal DNA are not transferred, while embryos containing healthy DNA are transferred to be used in the procedure. Thus, the treatment process begins for couples to have a healthy baby. (Genetic Examination and IVF)
Which genetic examination methods are used to increase success in IVF?
PGD/PGT tests are used to investigate genetic diseases and chromosome disorders. These are genetic diagnosis tests.
Preimplantation genetic diagnosis is also a test performed on embryos. The aim of the test is to select a healthy embryo. PGD is a strongly recommended method for screening for genetic predisposing diseases.

Genetic Examination and IVF test
Tests evaluated within the PGD test group;
- FISH (Fluorescence In Situ Hybridisation)
- Next Generation Sequencing (NGS, Next Generation Sequencing)
- Array CGH (Comparative Genomic Hybridisation)
In case of general screening, PGS tests are applied. PGS is commonly used in cases of recurrent pregnancy loss and in cases of advanced maternal age. The main purpose of the test is to take the embryo cell 5-6 days after egg collection, analyse its chromosome structure and then transfer the normal embryo to the uterus.
As a result, the reason why genetic examination is performed for the success of IVF treatment is to ensure the selection of healthy embryos with high reproductive potential. In this way, more successful IVF treatment processes are experienced.
