PGD, or pre-implantation genetic diagnosis uses IVF, in vitro fertilisation (fertilization of an egg in a laboratory dish or test tube) , to screen and scan embryos for any potential birth defects or conditions, such as Huntington’s Disease, Cystic Fibrosis or Downs Syndrome. PGD gives parents the options of being able to have healthy children, without the fear that they could inherit one of these many genetic conditions. PGD is used after two failed cycles of IVF, in which the egg and the sperm are artificially inseminated in a test tube. The Government funds some cycles of IVF and PGD, but it is a costly process – costing upwards from $10,000. After the failed cycles of IVF, or if there is a strong need for PGD testing due to genetic conditions of the parents, PGD is then suggested. Through the process of PGD, ovulation is tracked for the female, before the egg is removed for a cellular biopsy on day three of ovulation. The egg then has a small hole cut out of it through a laser, and small sections of DNA are removed for testing. It is possible of multiple eggs to be released for testing, so that only healthy embryos are replanted into the female. There is the possibility that none of the embryos are free of the genetic condition, in which case the couple are able to undergo another PGD cycle later in time. If more than one embryo are deemed as being healthy, they can then be frozen for later use. PGD is a strong socio-scientific issue, due to the variety of
