Patient's question:
How to determine the gender from a four-dimensional color ultrasound report?Doctor's answer:
No matter whether it's two-dimensional, three-dimensional, or four-dimensional ultrasound, determining the baby's gender isn't always accurate. Four-dimensional ultrasounds capture the baby in relatively clear detail. If the genital area is captured, there's no doubt about it. However, from the four-dimensional ultrasound photos I've seen, it seems that few actually capture the genital area. Moreover, determining the baby's gender through ultrasound is prohibited by the state.However, there are some folk methods that use ultrasound data, such as gestational sac size and biparietal diameter (BPD) minus femur length, to judge gender. Many mothers have participated in verifying these methods. This is the information I've collected, and you can refer to it.
1. Determining the baby's gender by subtracting the femur length from the biparietal diameter.
Method: If the difference between the biparietal diameter and the femur length is greater than 2.1, it's a boy. The larger the difference, the higher the likelihood of it being a boy. If the difference is less than 2.1, it's a girl. The smaller the difference, the higher the likelihood of it being a girl.
