A new research study published in the January 2012 edition of The FASEB Journal describes findings that could lead to a non-invasive test that would let expecting mothers know the sex of their baby as early as the first trimester. Specifically, researchers from South Korea discovered that various ratios of two enzymes (DYS14/GAPDH), which can be extracted from a pregnant mother’s blood, indicate if the baby will be a boy or a girl. Such a test would be the first of its kind.
