Click "Calculate" to see the gender probability

The calculator will provide you with the probability of your baby being male or female based on the input you provide.

How Gender Prediction Works

Gender prediction during pregnancy is based on several ultrasound measurements. The most common methods include:

Nuchal Translucency (NT) measurement
Femur length measurement
Abdominal circumference measurement
Crown-rump length measurement

Each of these measurements has different accuracy levels depending on the gestational age. Our calculator uses statistical data to provide the most accurate prediction based on your specific measurement.

Accuracy of Gender Prediction

The accuracy of gender prediction varies depending on several factors:

Gender prediction accuracy is typically around 90-95% for most measurements, but can be higher or lower depending on the specific measurement type and gestational age.

Some measurements are more accurate than others. For example, nuchal translucency measurements tend to be more accurate in the second trimester, while femur length measurements are more accurate in the first trimester.

Factors Affecting Gender Prediction

Several factors can affect the accuracy of gender prediction:

Gestational age at the time of measurement
Type of ultrasound measurement used
Quality of the ultrasound image
Technician experience and skill
Pregnancy complications

Our calculator takes these factors into account to provide the most accurate prediction possible.
