Preimplantation Genetic Diagnostics

About Preimplantation Genetic Diagnostics

Pre-implantation genetic diagnosis refers to a series of tests performed on pre-implanted stage embryos for genetic defects. The tests are conducted during an IVF cycle. The fertilized egg or embryo produced in the laboratory is tested before implanting into the patient’s womb.

Diagnostic Tests

Preimplantation Genetic Screening (PGS):

Preimplantation genetic screening or PGS is a unique diagnostic procedure. It is performed at an early stage of fertilization or embryo development during an IVF or ICSI cycle to screen the chromosomal abnormalities.

Many IVF failures are due to chromosomal abnormalities in the embryo. All women will at least have one chromosomally abnormal egg. Accordingly, all men will at least have one chromosomally abnormal sperm. This abnormality is affected by various factors. To prevent IVF from failing, the embryo is also screened for chromosomal abnormalities.

The Process

During this procedure, the doctor removes one or more cells from the embryo to count the number of chromosomes. Usually, this counting is done after 5-6 days of fertilization in the laboratory. Once the chromosome numbers are normal with no apparent abnormalities, the embryos are selected for transfer.

Pre-implantation Genetic Diagnosis (PGD):

Babies inherit genetic conditions from their parents. A pre-implantation genetic diagnosis (PGD) allows the doctors to check the genes of the embryo and prevent the risk of developing genetic disorders. This procedure is also called preimplantation genetic testing for monogenic diseases. 

The Process

During this procedure, the doctor removes one or more cells from the embryo to count the number of chromosomes. Usually, this counting is done after 5-6 days of fertilization in the laboratory. Once the chromosome numbers are normal with no apparent abnormalities, the embryos are selected for transfer.
