How quickly you can tell your baby’s gender depends on the detection method you use. You may want to know your baby’s gender so that you can choose an appropriate name, or you may need to know if your baby is at increased risk for gender-related genetic abnormalities.

In a Gender reveal Ultrasound, high-frequency sound waves are sent into the uterus. As these sound waves bounce, they meet internal surfaces, bounce, and generate on a computer screen like an image of the fetus. The ultrasound image can help detect abnormalities in fetal development, size, and growth of the baby, and gender of the baby. Most future mothers have an ultrasound of around 18-20 weeks that shows the baby’s gender, but ultrasounds are sometimes done at 16 weeks. Although the baby’s position and technician skills are important in determining the baby’s gender, this visual method is approximately 95% to 100% accurate for detecting sex at 20 weeks. Maternal body weight and fetal positioning can affect the ability of a sonographer to determine the gender of your baby.

Lots of obstetricians suggest an ultrasound to ensure your baby is developing at a normal pace when your pregnancy is in the second trimester. Although fetal ultrasound can often detect fetal intercourse around week 11 of pregnancy, the accuracy of the results increases with gestational age. At this point, an experienced sonographer or other health care professional can easily tell if you have a boy or a girl – as long as your baby cooperates and turns in the right direction and does not cover his private parts.
