If you have chosen to find out the sex of your baby, you are most likely going to do so via ultrasound. Typically an ultrasound is done for this purpose around the midpoint in pregnancy. It is technically called the fetal anatomy survey and it is done to look for fetal anomalies and not simply the sex of the baby. Most women will have one between 18-22 weeks of pregnancy.

Many families rely on ultrasound to tell the gender or sex of their new baby. How accurate that report is will depend on many factors including the age of the baby, the equipment used, the technician, and the cooperation of the baby.
