How to determine fetal gender with four-dimensional color ultrasound
Four-dimensional color ultrasound refers to an examination method that uses high-frequency sound waves to perform four-dimensional imaging of the fetus to obtain the internal structure and development of the fetus. For expectant mothers, the most interesting thing is how to determine the gender of the fetus through four-dimensional color ultrasound. The following will introduce how four-dimensional color ultrasound determines the gender of the fetus from four aspects.
Identify gender characteristics
For four-dimensional color Doppler ultrasound technicians, determining the gender of the fetus is mainly based on observing the characteristics of the reproductive organs. There are several obvious differences in the shape and structure of reproductive organs between male and female fetuses. In the medical profession, these distinctions are called \”gender-identifying characteristics.\” The most significant ones are the reproductive organs of male and female fetuses – penis and vagina, testicles and ovaries, as well as the location of the urethra of male and female fetuses. Four-dimensional color Doppler ultrasound technicians determine the gender of the fetus by accurately observing the differences in these reproductive organs.
Fetal position and posture
The position and posture of the fetus will also affect the gender judgment of four-dimensional color ultrasound. Affected by the position and posture of the fetus, the four-dimensional color Doppler ultrasound technician may find that the parts of some reproductive organs are not clear, leading to increased uncertainty in determining the gender of the fetus. Therefore, before having a four-dimensional color ultrasound, expectant mothers should move around as much as possible and avoid sleeping or other immobile states.
Gestational weeks and maternal weight
Gestational age and maternal weight are one of the factors that affect gender determination using four-dimensional color ultrasound. Pregnant women who are overweight or who are too young in gestation will lead to poor four-dimensional color ultrasound imaging, thus adversely affecting the determination of fetal gender. In addition, if the gestational age is too small, it is easy to confuse the fetal reproductive organs with other structures, leading to misjudgment.
Is four-dimensional color ultrasound accurate in determining fetal gender?
Because four-dimensional color ultrasound is a medical technology with extremely high resolution, it can accurately observe the reproductive organs of the fetus and confirm the gender of the fetus. Under normal circumstances, when a four-dimensional color ultrasound is performed around 20 weeks of pregnancy, the accuracy of determining the gender of the fetus is as high as 95% or more. Of course, in order to avoid misdiagnosis, it is recommended to determine the gender of the fetus when multiple four-dimensional color ultrasounds have consistent conclusions.
Summary
When determining the gender of the fetus with four-dimensional color ultrasound, multiple factors such as gestational age, maternal weight, fetal position and posture need to be considered. By carefully observing the characteristics of the reproductive organs, the gender of the fetus can be accurately identified. Although there are occasional misjudgments, in general, the accuracy of four-dimensional color ultrasound is very high. Therefore, expectant mothers can also observe the gender of the fetus during the four-dimensional color ultrasound examination in the second trimester to better prepare for pregnancy and delivery.
