How do you know boy r girl from tiffa scan?

A Tiffa scan, or targeted fetal imaging scan, typically performed between 18 to 20 weeks of pregnancy, can reveal the sex of the baby by examining the genitalia. During this ultrasound, trained technicians look for specific anatomical markers: a penis and scrotum indicate a boy, while the absence of these markers, along with the presence of labia, suggests a girl. However, it's important to note that while these scans are generally accurate, there is still a small chance of error. Always consult with your healthcare provider for the most reliable information.
