The upside of the fetal DNA method is that it can reveal gender earlier and with more accuracy than an ultrasound, and without the invasiveness—and thus small risk of miscarriage—of amniocentesis and chorionic villus sampling.
The downside, some warn, is easier gender selection.
How can you tell from a blood test if its a boy or girl?
For the blood tests, women prick their fingers and send blood samples to labs. If the Y chromosome is detected, the fetus is male.
Can hCG levels determine gender?
New research has found that it is possible to tell almost from the start of pregnancy whether the foetus is male or female, based on the levels of a hormone called called human chorionic gonadotrophin (HCG) in the mother’s blood. The presence of HCG is already used to detect pregnancy in home-testing kits.
What week can gender be determined?
This is one of the most common questions doctors get from parents-to-be. If you’re dying to know whether to stock up on pink or blue onesies, you’ll likely have to wait until you’re about 18 to 20 weeks along. Doctors can usually determine the baby’s sex during a routine ultrasound visit at this time, but not always.
