How to determine fetal gender
During pregnancy, the gender of the fetus is a very critical piece of information for parents. Modern medical technology is becoming increasingly advanced, and four-dimensional color ultrasound is a technology that can provide fetal gender information. So, how does four-dimensional color ultrasound determine the gender of the fetus? This is elaborated on from four aspects below.
Observe fetal genitals
The most common method is to determine the gender of the fetus by observing the fetus\’ genitals. Four-dimensional color ultrasound can directly observe the fetal genitals through the control of an obstetrician and gynecologist. At about 20 weeks of pregnancy, the fetus’s external genitalia can be observed more accurately through four-dimensional color ultrasound. If the fetal external genitalia is long and strip-shaped, it is a boy; if it is a line or Y-shaped, it is a girl. When observing the fetal genitals, it is also necessary to make judgments based on other factors, such as the shape of the fetal head, limbs, etc.
Observe the color of the fetus
In addition to observing the genitals, four-dimensional color ultrasound can also infer the gender of the fetus by observing the color of the fetus. Because male fetuses need to synthesize testicles and their bodies contain hormones such as testosterone, they tend to appear green or blue in four-dimensional color ultrasound, while female fetuses tend to appear pink. This color difference is also one of the basis for obstetricians and gynecologists to determine the gender of the fetus, but it cannot be determined by one method alone.
Observe blood vessel flow
In addition to observing the fetal genitals and color, four-dimensional color ultrasound can also infer the gender of the fetus by observing the flow of blood vessels in the fetus. The specific method is to determine the gender of the fetus through the flow direction of the blood vessels in the fetal pelvic cavity. At about 18 weeks of pregnancy, boys will magically send their testicles into the scrotum; girls do not have this kind of blood flow because they do not have the formation of this organ. The technical term is blood flow from the cavernous artery of the penis or the vulvar artery.
Observe other factors
Although observing the fetal genitals, color, and blood vessel flow is the main basis for four-dimensional color ultrasound to determine the gender of the fetus, obstetricians and gynecologists also need to combine other factors to make judgments, such as the pregnant woman\’s belly shape, the pregnant woman\’s fetal gestation period, the pregnant woman\’s pregnancy period, etc. Etc., these factors will all have an impact on the judgment of fetal gender.
Summary
Through the introduction of the above four aspects, we can know that four-dimensional color ultrasound, as one of the important technologies in modern medicine, can provide us with fetal gender information. However, since determining the gender of the fetus is affected by many factors, it is recommended that the gender be determined by a doctor’s independent judgment. In short, we need to stay positive and optimistic during pregnancy and avoid negative effects on ourselves and the fetus.
