Pre-implantation Genetic Diagnosis (PGD)
PGD is generally used to detect anomalies in the number or structure of the chromosomes of embryos.
Genetic screening is one of the latest and most sophisticated techniques used to test for genetic disorders by direct examination of the DNA itself.
The method of genetic screening used in In-Vitro Fertilisation (IVF) is pre-implantation genetic diagnosis (PGD).
PGD is generally used to detect anomalies in the number or structure of the chromosomes of embryos.When embryos have abnormal chromosomes, this may prevent implantation to the uterine lining, lead to pregnancy loss, or result in the birth of a child with physical and/or mental disabilities.PGD may help prevent these adverse outcomes by identifying affected embryos as they are developing in the laboratory before being transferred back to the patient’s uterus during the IVF cycle.
