genetic screening

             Genetic screening, also known as preimplantation genetic diagnosis (PGD), is a newly emerging
             technology that has brought with it much controversy. PGD involves the in vitro fertilization of an
             embryo. “The embryos are allowed to develop to a 6 to 10 cell stage, at which point one of the
             embryonic cells is removed from each embryo and the cellular DNA is analyzed for chromosomal
             abnormalities or genetic mutations” (Botkin, 1998). In doing this, it can be determined which
             embryos will be most likely to implant and germinate successfully in the uterus. PGD is a
             complicated, technologically sophisticated process. It is a union of in vetro fertilization
             technology and molecular biology (Botkin, 1998). Though it has numerous positive attributes,
             there are equally as many negative ones. In fact, this issue is one that has recently become the
             subject of many heated debates. Proponents for the use of PGD assert that this test allows for
             parents with fertility problems to maximize their opportunity for conception and birth. Their
             adversaries argue that this process is morally questionable, and though it is seen as safe alternative
             to abortion couples can experience the same psychological effects as if they were dealing with an
             actual abortion (Botkin, 1998). Obviously, this is an issue that does not have one distinct answer.
             Each opposing side has raised some poignant arguments.
             Those who are in favor of PGD generally use the arguments that it allows for the
             transmission of human genetic diseases to be reduced (McClure and Tasca, 1998). Before the
             usage of PGD the only other way to determine the existence of genetic diseases was by the use of
             prenatal diagnosis in the form of amniocentesis or chronic villus sampling (CVS). Currently, CVS
             can only be performed in the ninth to eleventh week of pregnancy, and amniocentesis can be
             performed in fifteenth to eighteenth week (McClure and Tasca, 1998). At ...
