The most common method to find out the sex of your baby is by ultrasound. The results of an ultrasound are most accurate when you’re between 18 and 22 weeks pregnant. It is done at the fetal anatomy survey in the second trimester.
There are many factors that can influence the accuracy of the ultrasound. They include:
- the gestational age of baby
- the quality of the equipment
- the experience of the person doing the ultrasound
- mother’s weight
- baby’s position
Other methods of sex prediction are more accurate but carry risk to the pregnancy. The most commonly used methods are amniocentesis and chorionic villus sampling. This method is about 100% accurate.
