Simple Blood Test Can Determine Fetal Sex at Seven Weeks
The New York Times: Test Can Tell Fetal Sex at 7 Weeks, Study Says, by Pam Belluck:
A simple blood test that can determine a baby’s sex as early as seven weeks into pregnancy is highly accurate if used correctly, a finding that experts say is likely to lead to more widespread use by parents concerned about gender-linked diseases and those who are merely curious, as well as people considering the more ethically controversial step of selecting the sex of their children.
The appeal of the test, which analyzes fetal DNA found in the mother’s blood, is that it can establish sex weeks earlier than other options, like ultrasound, and is noninvasive, unlike amniocentesis and other procedures that carry small risks of miscarriage. . . .
