As the article explains, such a test has value to help parents prepare not just for a little boy or girl but to also prepare for some potential maladies that may be most associated with one sex over the other. The premier problem is our propensity to gather information that we are not prepared to process so that in the end, if the news is different than what we want, the child will die.
Sex selected abortions occur. While the article notes that companies try not to sell this product for that purpose, it happens nevertheless.
I favor any testing we can do to help in the treatments of any malady we uncover. To use tests to “search and destroy” children that are not “perfect” is offensive to the Creator and to those of us who value life. To abort a child because it is of the wrong sex is equally wrong and also extremely shallow.
