Most often the gender of a fetus is determined by looking at the genitals on an ultrasound. For a more reliable answer, expecting parents can use chorionic villus sampling or amniocentesis. However, a new study has found that a simple, non-invasive blood test will be able to reliably determine the gender of a fetus at 7 weeks. The blood test is currently used in Europe and will probably be available in the US in 2012.
