Determining the sex of a baby is most reliably done through an ultrasound.
Ultrasound: The Primary Method
The most common and accurate method to determine the sex of a baby is an ultrasound. This non-invasive procedure uses sound waves to create an image of the fetus. Between 18 and 20 weeks of pregnancy, a detailed anatomy scan is typically performed, which includes assessing the baby's genitals to determine the sex. The ultrasonographer examines the fetal genitalia for specific markers that indicate whether it's a boy or a girl. It's important to note that while ultrasound is highly accurate, it's not foolproof, and there's a small chance of misidentification.
Accuracy and Limitations
While ultrasound is the primary method for sex determination during pregnancy, it's crucial to understand that the accuracy depends on several factors, including the baby's position and the clarity of the ultrasound image. In some cases, the sex might be unclear, requiring a follow-up scan.
