). At this point, the fetus is
             developing within the uterus. Discovery of any abnormalities would pose the parents of the fetus
             with a difficult decision. They either continue a pregnancy that will result in a genetically defected
             child or abort the fetus. This is where PGD allows for what some would say an easier option.
             Because PGD is a pre- pregnancy test, abnormalities can be detected prior to the embryo ever
             being inserted into the mother. Currently, there are several diseases that PGD can detect such as
             Cystic Fibrosis, Tay-Sachs disease, Duchenne Muscular Dystrophy, Fragile X Syndrome, and
             Down Syndrome (McClure and Tasca, 1998). These are only a few of the diseases that can be
             detected but as the knowledge concerning human DNA increases there will be more detectable
             diseases. In addition to disease detection, PGD can also detect the gender of an embryo which
             can enable the determination of the existence of sex-linked disease or a sex chromosome
             imbalance (McClure and Tasca, 1998). Another of PGD's benefits is its ability to assist women
