Finding out the gender of the baby is one of the biggest things many families look forward to during pregnancy, whether they have a preference or not.

Most average pregnancies in the United States undergo two ultrasounds -- one at the end of the first trimester, around 9-13 weeks, and another around the end of the second, around 18-22 weeks, the latter being the "gender ultrasound" most frequently.

But now researchers have found a way to find out the baby's sex at the first ultrasound with 97% accuracy. Researchers did a transvaginal ultrasound at 6 weeks on more than 5,300 women and hypothesied gender due to one marker. Then a transabdominal ultrasound (the one on your belly) at 18-20 weeks, and their method of gender determination was right 98-99 percent of the time!

The location of the placenta is what researchers used to determine the sex of the baby -- 97.2 percent of boys had their placenta on the right side of the uterus at that 6 week ultrasound, and 97.5 percent of girls had theirs on the left. According to their study, this method should be considered "highly reliable" in determining gender within the first few weeks of pregnancy.
