This achievement, reported last week in the Journal of the American Medical Association, is a potential boon to parents who fear their children are at risk for a sex-linked condition. If, for example, a particular disease affects only males and a fetus is female, a woman can avoid further invasive tests, such as amniocentesis, which carry a risk of miscarriage.
But this technology is igniting a heated ethical debate before it is even clinically available. Many fear that it will be used for a reason that has nothing to do with medical outcomes. They fear parents will use it for sex selection, aborting healthy fetuses that are of an unwanted sex.
They are probably right.
