It takes a long time for us to judge whether we are pregnant with a boy or a girl through B-ultrasound. Everyone should know that 10 will give birth to a healthy baby, and the changes of pregnant women during pregnancy are also worthy of our attention. Let's learn about B-ultrasound to determine whether it is a boy or a girl.
B-ultrasound to judge pregnant male or female 1 Teach you how to judge male or female with B-ultrasound.
First: Look at the data. If the length and width are more than doubled, the baby is more likely to be a boy. Baby girls are more likely to be equal in length and width.
Second: Look at the shape. Eggplants or long strips are more likely to be male babies, and round ones are more likely to be female babies.

After reading the B-ultrasound above, I believe you should have a certain understanding. Experts remind that the method of fetal sex prediction is not 100% accurate, so we should not blindly listen to it.
When you are pregnant 18 ~ 20 weeks, the B-ultrasound doctor can identify the sex of the fetus through B-ultrasound examination, provided that your baby is very cooperative. His posture at that time must let the B-ultrasound doctor see his genitals. Moreover, even if the B-ultrasound doctor can see the genital parts of the fetus, the image may not be clear. All these will affect the accuracy of B-ultrasound to see the sex of the fetus.
The more experienced the B-ultrasound doctor, the higher the quality of the B-ultrasound scanning instrument, and the higher the accuracy of B-ultrasound to see the sex of the fetus. However, even the best B-ultrasound doctors are usually not 100% sure whether you are pregnant with a boy or a girl. Moreover, what you need to know is that in Chinese mainland, fetal sex identification for non-medical reasons is prohibited.
Medically speaking, it is easy to see the sex of the fetus when you have a B-ultrasound examination about 20 weeks (four months) pregnant, provided, of course, that the doctor who gave you B-ultrasound can see the key parts. In this period, the difference between boys and girls has been obvious. As pregnancy progresses, this difference will become easier to identify. If there is enough amniotic fluid around your baby and his feet are not nailed between his legs, then B-ultrasound in the third trimester can usually identify the sex of the fetus.
However, it is not so easy to do B-ultrasound examination in the first trimester to identify the sex of the fetus. Because the sex of the fetus is determined by genes when pregnant. But in the initial stage of fetal development, boys and girls look the same.
All embryos have a small bud or protuberance on their genitals. If you are pregnant with a boy, around 7 weeks of pregnancy, the fetus begins to secrete testosterone, which will stimulate the bud development on the genitals and form the penis and scrotum. If you are pregnant with a girl, the buds in this genital area will develop into clitoris and labia.
The development of the genitals of boys/girls is a gradual process. Only when you are pregnant 1 1 week (80 days), the appearance of different sex fetuses begins to differ. At this time, all the genitals of the fetus have a protrusion. For boys, this protrusion often extends upward, and the angle with the spine is greater than 30? Comparatively speaking, the protruding direction of female genitals will appear horizontal, and the included angle with the spine is less than 30? .
Friendly reminder: If you want the B-ultrasound doctor to see the sex of the fetus, the position of the fetus in the mother must be back down and face up.
Experts suggest that as long as a healthy baby is born, boys/girls should not care too much. Unless your family has a history of genetic diseases related to sex, it is not recommended that you do fetal sex identification in the second trimester.
Judging whether it is a boy or a girl by B-ultrasound. 2 How to predict the sex of the fetus from B-ultrasound?
Although the baby's sex can't be known from the doctor after B-ultrasound. However, we can get a glimpse from the B-ultrasound list.
1, look at the data-if the gestational sac is more than doubled in length and width, it is more likely to be a boy. Baby girls are more likely to be equal in length and width.
2, look at the shape-pregnancy sacs like eggplant or long strips are more likely to be male babies, and round ones are more likely to be female babies.
3. Look at the biparietal diameter and femoral length-the biparietal diameter is the transverse diameter of the fetal head, and the femoral length is the length of the fetal femur. There is a saying that the short head and thigh is a boy, that is, the biparietal diameter-femoral length >; 2. Girls with little difference in head and legs.
Step 4 look at the data
BC data of 7W+ 1D: fetal sac 2.95438+0. 9 gave birth to a boy.
9W+4D BC data: See uterus 46.630. 2mm gestational sac twins are both girls.
BC data of 60 days: gestational sac size is 3.6 1. 6MM gave birth to a boy.
5W+6D. Gestational sac: 25mm 1 1mm for boys.
Embryo sac: 23× 17× 16 gave birth to a girl.
Data of 46 days BC: gestational sac: 20 17 17 girl.
7w+1d: BC results of 3220 mm gestational sac girl.
At 8 weeks, it was 1.6× 1.7, and it was a girl.
At 8 weeks, it was 4 128MM, and it was also a girl.
BC over 8 weeks, fetal sac 19MM 10MM. Later, BC took a picture, also a boy.
Of course, these are just prediction methods circulating in the market, and they are not the best methods that mothers believe. It is best to make it clear that it is a happy event to do a good job in nutrition, health care, etc. and happily accept the arrival of every new life, whether male or female, as long as he (she) is healthy.
Judging whether you are pregnant with a boy or a girl by B-ultrasound. Some tips for understanding b-ultrasound.
The biparietal diameter (BDP) refers to the maximum distance between the parietal bones on both sides of the fetal head, also known as the "large transverse diameter of the head".
It should reach more than 9.3 cm at full term. According to the general rule, after 5 months of pregnancy, this value is basically the same as that of the month of pregnancy, that is, the BPD is about 7.0 cm at 28 weeks of pregnancy, 8.0 cm at 32 weeks of pregnancy, and so on. After 32 weeks of pregnancy, it is normal to grow by about 0.2 cm per week on average. This value can be used to calculate the fetal gestational age and estimated weight.
Head circumference (HC): the length of the ring head made on the plane of parietal bone on both sides. Combined with biparietal diameter, we can know the shape of fetal head and judge the development state of the head, which is also one of the important parameters to estimate body weight.
Femoral length (FL): The length of fetal thigh bone, that is, the bone from the root of thigh to knee, also called "thigh bone length, femoral bone length".
The difference between the normal value and the BPD value of the corresponding pregnancy month is about 2~3 cm. For example, the BPD is 9.3 cm and the femur length should be 7.3 cm. BPD is 8.9 cm, and the length of femur should be 6.9 cm.
Abdominal circumference: the length of one week of the stomach.
Placenta (PL): Position refers to the position of the placenta in the uterine cavity. The normal placenta should be attached to any part of the upper part of the uterus, and the full-term placenta thickness is between 2.5 and 5 cm.
Umbilical artery blood flow ratio (S/D): The ratio of umbilical artery systolic blood pressure to diastolic blood pressure is to know the blood supply of maternal placenta by measuring umbilical artery blood vessels.
Generally, it is meaningful to measure the S/D value after 20 weeks. Generally speaking, the S/D ratio is greater than 3.0 at 20 weeks of pregnancy, and gradually decreases after 28 weeks of pregnancy, often lower than 3.0.
Fetal movement: Fetal movement can be seen by B-ultrasound in 8 ~ 9 weeks of pregnancy. Strong is normal, weak may indicate that the fetus is asleep.
Fetal heart: Fetal heart beat can be seen by B-ultrasound at the 7th to 8th week of pregnancy and the 6th weekend of the earliest pregnancy. The normal frequency of fetal heart beat is between 120 ~ 160 beats per minute.
