Parents have a right to acquire and act upon medical information  This argument comes from the idea, that a body is the property of its owner, as well as a fertilized egg is the property of the couple that created it whom also have parental rights  a) Self-determination  Some proponents of genetic screening might go as far to create the distinction between an embryo and a child: considering an embryo not to be a living being, but rather just a mass of cells, makes it possible to avoid entirely considering the "screening" process as a selection process between living human beings. Rather, it could be interpreted merely as a selection between different organizations of cells that have differing potential to become healthy "life".  b) Parental rights  Currently we allow couples to choose not to have children due to their own genetic deformations. We allow them to tie their tubes, get sterilized due to their own decision not to have children with genetic defects or children at all.  Experts suggest, that due to the sanctity of parental rights, the principle decision making should be in the hands of the parents, also regarding the power over the future of their DNA. With this, the society respects the principal decision making right of the individual to control their family and the destiny of their offspring (1).  Mainly making it a next step in deciding what their course of action regarding children will be.  1 Renee C.
