At 16 weeks of pregnancy, it is already four months of pregnancy. At this time, expectant mothers can determine the gender of the fetus based on various characteristics, but many claims about judging the fetus are not accurate. In fact, when the fetus is four or five months pregnant, the reproductive organs of the fetus have already grown enough to be seen through ultrasound, but the doctor won't tell you.
The gender of a baby can be determined by ultrasound examination at 4-5 months of pregnancy, based on the condition of the baby's external genitalia. The results of B-ultrasound examination at 16 weeks of pregnancy should be relatively accurate, but China's law prohibits the identification of fetal gender for non-medical purposes.
How to determine fetal gender from ultrasound data? Generally speaking, the data on the ultrasound sheet includes biparietal diameter, abdominal circumference, femur length, gestational sac, fetal heart rate, etc. The placenta, amniotic fluid, umbilical cord, fetal spine, and other conditions can also be observed from the ultrasound. According to folk belief, fetal gender can be determined through ultrasound data using the following methods:
1. Checking the gestational sac: By looking at the B-ultrasound scan taken at 40-50 days of pregnancy, the size and shape of the gestational sac can be observed to determine the gender of the fetus. If the shape of the gestational sac is elliptical or circular, it is for female babies, and if it is elongated, it is for male babies.
2. Look at biparietal diameter and femur length: biparietal diameter refers to the transverse diameter of the fetal head, while femur length refers to the length of the fetal thigh bone. The older generation's belief is that boys have shorter head and thigh bones, that is, biparietal diameter minus femur length is 2, and girls have the smallest difference between head and leg bones.
The four-dimensional color ultrasound diagnostic device is currently the most advanced color ultrasound equipment in the world. Many pregnant women who have undergone four-dimensional color ultrasound will habitually ask the doctor whether the fetus is male or female. Although 4D ultrasound can clearly identify the gender of the fetus, during the examination process, in order to avoid revealing the gender of the fetus, doctors will actively avoid the gender characteristics and lower body of the fetus. At the same time, in the later production of CDs, the parts that may reveal the gender of the fetus will also be processed.
So, although 4D ultrasound can detect the gender of the fetus, it is illegal to distinguish between male and female fetuses for non-medical purposes according to national regulations. Regular hospitals will not tell or imply the gender of the fetus through any means.
Through the introduction in this article, it can be known that at 16 weeks of pregnancy, the gender of the fetus can be seen through ultrasound. However, China does not allow the identification of fetal gender, so even if the accuracy of ultrasound in identifying fetal gender is very high, doctors will not tell you the gender of the fetus. It is best not to have unrealistic expectations.
