Preimplantation Genetic Diagnosis (PGD) is a relatively new technology that allows parents to screen and select embryos with specific genetic traits. This process has sparked controversy and raised ethical questions about the possibility of creating “designer babies.” In this blog post, we will explore the concept of PGD, its uses, potential benefits and drawbacks, and the ethical considerations surrounding it.

Preimplantation Genetic Diagnosis, also known as embryo screening, is a technique used during in-vitro fertilization (IVF) to identify genetic abnormalities in embryos before they are implanted in the mother’s uterus. This allows parents to select embryos that are free of genetic diseases or have desirable traits such as eye color, hair color, or gender.
PGD involves removing one or two cells from a developing embryo and analyzing them for specific genetic markers. This is typically done on the fifth day of embryo development when the embryo has around 100 cells. The cells are then tested for genetic disorders, and only the healthy embryos are transferred to the mother’s uterus for implantation.
One of the main uses of PGD is to help couples who are carriers of genetic diseases have healthy children. By screening embryos for genetic disorders, parents can avoid passing on diseases to their children. This is especially beneficial for couples with a family history of genetic diseases such as cystic fibrosis, sickle cell anemia, or Huntington’s disease.
PGD also has the potential to prevent the transmission of genetic disorders that are linked to gender, such as hemophilia, a bleeding disorder that affects mostly males. By selecting only female embryos, couples can eliminate the risk of passing on the disease to their children.
Preimplantation Genetic Diagnosis: A Tool for Creating Designer Babies?
Aside from medical uses, PGD has also been used for non-medical reasons, such as selecting the gender of the baby or choosing certain physical traits. This has raised concerns about the possibility of creating “designer babies,” where parents can essentially customize their child’s genetic makeup.
Proponents of PGD argue that it can help prevent the birth of children with debilitating genetic disorders and allow parents to have healthy children. They also argue that it is a form of reproductive autonomy, giving parents the right to choose what they consider best for their family.
On the other hand, critics of PGD raise concerns about the potential misuse and abuse of this technology. They argue that it could lead to a society where people are valued based on their genetic traits, creating a divide between those who can afford to use PGD and those who cannot. There are also concerns about the potential for discrimination against individuals with genetic disorders or traits that are considered undesirable.
Another ethical consideration is the potential for PGD to be used for non-medical purposes, such as selecting the gender or physical traits of a child. This raises questions about the extent of parental control over their child’s genetic makeup and the impact it may have on the child’s sense of identity.
Moreover, PGD is not a foolproof method, and there is a chance for misdiagnosis or errors in the testing process. This could lead to the transfer of embryos with genetic disorders, which goes against the main purpose of using PGD.
Despite these concerns, PGD continues to be a popular option for couples undergoing IVF. It is estimated that around 10% of IVF cycles in the United States involve the use of PGD.
In conclusion, Preimplantation Genetic Diagnosis is a powerful tool that has the potential to help prevent the birth of children with genetic disorders. However, its use for non-medical purposes and the ethical considerations surrounding it cannot be ignored. As technology continues to advance, it is crucial to have ongoing discussions and regulations in place to ensure responsible and ethical use of PGD.
