Preimplantation diagnosis (PGD) is a procedure that allows the analysis of the genetic material of embryos obtained as a result of artificial insemination (IVF) before their transfer to the uterus. The purpose of PGD is to identify genetic abnormalities or hereditary diseases in embryos in order to select healthy embryos for transfer.
The process of preimplantation diagnosis usually includes the following steps::
- Examination of genetic material: Embryos obtained as a result of IVF are subjected to biopsy, during which a cell is taken for genetic analysis.
- Genetic analysis: The obtained samples of genetic material are analyzed in order to detect the presence of genetic abnormalities or hereditary diseases.
- Selection of healthy embryos: Based on the results of genetic analysis, healthy embryos are selected for transfer to the uterus.
PGD can be used to identify various genetic abnormalities such as Down syndrome, cystic fibrosis, hereditary forms of cancer and other hereditary diseases. This procedure reduces the risk of transmission of genetic diseases to offspring and increases the likelihood of a successful pregnancy during IVF.
It is important to note that PGD is an ethically debated topic and may be regulated by legislation in various countries.
