Yes, a baby's gender can be checked. The most common method is an ultrasound.
Determining Baby's Gender: Ultrasound
An ultrasound uses sound waves to create an image of your baby inside the womb. This image can often reveal the baby's sex. While not always perfectly accurate, ultrasounds can typically determine the sex as early as 14 weeks, though most doctors schedule them between 18 and 21 weeks for this purpose. [Source]
Accuracy of Ultrasound in Gender Determination
It's important to note that while ultrasound is the most common method, it is not always 100% accurate in determining the baby's gender.
When to Expect Results
The timing of an ultrasound can vary. While gender determination might be possible as early as 14 weeks, a more accurate assessment is often achieved between weeks 18 and 21 of pregnancy.
