A simple blood test might tell you the sex of your unborn baby.

That's the conclusion of research published in the latest issue of the journal Obstetrics and Gynecology.

Between 2003 and 2009, researchers tested women who were between eight and 10 weeks pregnant, examining DNA from their blood samples to predict the sex of the babies in 186 pregnancies. They predicted 105 boys and 81 girls.They were right every time.

It's good news for parents, says researcher Dr. Peter Scheffer, M.D., of the University of Amsterdam. "It eliminates the dangers associated with invasive testing," he tells MSNBC.

Determining the sex of an unborn baby can lead to early detection of certain disorders. Genetic diseases such as hemophilia and Duchenne muscular dystrophy are carried by the X chromosome that almost always occurs in males.

Critics worry an evil genie might be let out of the bottle as fetal testing evolves. Parents might not always like what they find out. "Elective abortion is just about the only option in response to fetal testing," bioethicist Arthur Caplan, Ph.D, of the University of Pennsylvania, tells MSNBC.

However, critics may be too late to cork the bottle. Researchers concluded in Obstetrics and Gynecology that, "Noninvasive fetal sex determination in maternal plasma is highly reliable and clinically applicable."

What do you think? Should we be able to find out our unborn baby's gender so quickly?
