Preimplantation Genetic Diagnosis (PGD)Embryo and the Law

Preimplantation Genetic Diagnosis (PGD) involves the removal and analysis of 1-2 cells from a 6-10 cell stage embryo that has been created in-vitro. Embryos that are free from a genetic condition can then be transferred to the uterus whilst those that are positive for the disorder can be allowed to expire or be donated to research.

Its widespread use began in the 1990s to provide women with an alternative to prenatal diagnosis, since it spared them the potential of undergoing the harrowing decision as to whether to abort their baby if it were found to have such a disorder.

Conditions presently tested for include:

  • Huntington’s disease
  • Cystic Fibrosis (CF)
  • Chromosomal disorders
  • Predisposition to certain cancers
  • Sex-linked disorders
