"A May analysis in The Lancet estimates that between 4.2 million and 12.1 million female fetuses were "selectively" aborted in India from 1980 to 2010"Although many would be able to use this information for good, such as testing for rare gender-based diseases and other genetic disorders, many feel that the abortion rate would increase due to gender-selection.
It is well known that India and China have long practiced gender-selection, and a tool like this may make it even easier. It is much easier, and some consider less amoral to abort a fetus during the first trimester. Currently, gender can't be determined until around the 20th week via ultrasound.
Not sure where I stand on this one. I have no desire personally to know the gender of my child before he or she is born. If my child was at risk for a gender-specific genetic disease, I may choose to find out, but only that it may prepare my mentally for the possibility of a special needs child, not so I could abort a potentially imperfect baby.
