    Preimplantation genetic diagnosis option on a slippery slope?

    By Carrie A. Zabel, M.S., C.G.C.

Prenatal testing comes in many forms and requires a thoughtful decision.

Some individuals choose no testing; others choose non-invasive options, such as first-trimester screening, to determine their level of risk for select genetic conditions such as Down syndrome.

Others may elect invasive medical procedures, such as chorionic villus sampling or amniocentesis, to determine whether or not the child will be born with a genetic condition. As if these decisions weren't complicated enough, new genetic technologies make it possible to determine even more about a child's health.

Preimplantation genetic diagnosis (PGD) can be used as part of the in vitro fertilization process to select embryos with given characteristics. For instance, some families may have a known genetic condition in their family which they wish to avoid passing on to future generations. Following the fertilization of an egg with a sperm outside the body, the embryos are tested to determine if they have the trait which is hoped to be avoided. The embryos that do not carry the trait are then selected for implantation.

Some professionals are concerned that the process of PGD is an ethical "slippery slope". How do we decide which traits are appropriate to select for and which aren't? Recently, the Fertility Institute, a fertility clinic in California, advertised to prospective parents an increased chance of having a baby with their choice of hair, eye and skin color, if they used their PGD services. Is this appropriate? Or, is this irresponsible use of a technology which is meant to be used to prevent children from being born with serious medical conditions? Who should decide?

Please share your thoughts.
