PGD & PGS

Preimplantation genetic diagnosis (PGD) and Preimplantation Genetic Screening (PGS) allows screening of embryos prior to implantation for genetic and chromosomal abnormalities to select the best possible embryo for transfer.

Preimplantation genetic diagnosis (PGD) is particularly beneficial to couples who may be at risk of passing on a known genetic condition to their children such as:

  • Huntington’s disease
  • Cystic Fibrosis
  • Sickle Cell Anaemia
  • Tay-Sachs disease
  • Haemophilia A
  • Achondroplasia (dwarfism)
  • Muscular Dystrophy

Patients considering PGD generally carry genes associated with a serious genetic disorder and seek PGD with the aim of having a child free of disease.

The process involves removing a few cells from embryo(s) at the Day 5 or Day 6 stage of development after fertilisation (embryo biopsy) and evaluating whether they carry any causative genes. The embryos are frozen after the biopsy, while the genetic testing is being undertaken.

If the genetic testing confirms patients have embryos unaffected for the genetic condition being screened for, one is selected for implantation and the remaining embryos stored for potential future use.

PGD will allow Alison to determine the genetic health of your embryo and increase your chances of a healthy pregnancy.
