Are there any hints of men and women on the B-ultrasound list?
90% of these words are male treasures on the B-ultrasound list.
The most accurate way to see men and women through B-ultrasound.
The baby boy's B-ultrasound is like this.
It is now forbidden to identify the sex of the fetus through B-ultrasound examination. And many doctors, unless it is for special reasons. But I couldn't stop the curiosity of some mothers, so I began to study the B-ultrasound list of each pregnancy test. I want to understand the mystery through some data inside. Below I have synthesized a few more reliable statements, which are only for entertainment and satisfy everyone's curiosity. I hope it can relieve the pressure and bring some fun to my anxious mother during pregnancy.
First, judge men and women according to gestational sac data (three values are needed to judge):
Giving birth to a boy and a girl, in fact, has long been finalized. For example, boys grow up two months before pregnancy, and girls are oval or round. Take the following data as an example: 28*26* 14, boy. Why must there be three data? For example: 40*20mm gestational sac, so there is no way to judge. On the surface, the difference between the two data is twice, so it should be a boy. Wrong, because there is no third data. If it is 40*40*20, it must be a boy.
Second, twice the diameter of parietal bone reduces the length of humerus.
The biparietal diameter (BDP) of the fetal head refers to the length of the widest part between the left and right sides of the fetal head, also known as the "large transverse diameter of the fetal head". Femoral length (FL) is the length of fetal femur, also known as "femur length, femur length", which refers to the length of femur from the root of fetal thigh to the knees.
A man whose biparietal diameter minus the femur length is greater than 2 is a male treasure, with an accuracy rate of 80%, otherwise he is a girl.
If the biparietal diameter minus the femoral length is greater than 2, it is a boy. (20% are girls)
If the biparietal diameter minus the femoral length is less than 2, it is a girl. (20% are boys)
Generally speaking, boys have bigger heads.
Third, the fetal heart rate
About 140 is generally a male baby, and above 150 is generally a female baby.
Four. Separation of renal pelvis
Renal pelvis separation generally occurs in male babies, and female babies generally do not have renal pelvis separation. Mothers-to-be should not panic when told by doctors that the renal pelvis is separated, which is probably caused by the child's urine. The separation of renal pelvis below 1CM has no pathological significance, so don't worry. So in the meantime, congratulations on your birth.
Five, Down's screening index can detect the sex of the fetus.
First of all, look at the MOM value of b-HCG: below 0.4, most of them are boys; 1.0 above, most of them are girls; 0.4 to 1.0 is a critical range, which is possible for both men and women.
Then, it is more accurate to combine two values (b-HCG and AFP):
The lower the MOM value of b-HCG (; 1), the more likely it is to be a boy;
The higher the MOM value of b-HCG (>; 0.8), the lower the MOM value of AFP (
6. Is it X or Y?
Any mid-late B-ultrasound sheet (early pregnancy can not be displayed), look at the top of the B-ultrasound image, there will be letters showing Y or X in the middle of the row. If it is Y, it means that you are pregnant with a girl and X is a boy. For a female baby, the "three lines" are obvious marks. For a male baby, the "protruding thing" is his mark: if you see a ball, if you see a ball and a small intestine, it's all JJ!
Are there any hints of men and women on the B-ultrasound list?
The sex of the fetus has always been a special concern of many prospective parents. How to know the baby's sex in advance? After pregnancy, curious prospective parents always hope to test whether they are pregnant with male treasures or female treasures through various folk methods. Recently, it has been circulated in Weibo that you can know whether the baby in your belly is male or female by watching B-ultrasound. Is there any scientific basis?
When you are pregnant, are you curious and can't wait to know the sex of the baby? Or do you want to remain mysterious until the last minute? The experienced older generation is always "observant". When they see the pregnant mother, they can't help but enthusiastically infer whether the baby in the belly is male or female ... Recently, it has been circulated on the Internet that the sex of the fetus can be known by watching the B-ultrasound. what do you think? Is it credible?
First, look at the B-ultrasound examination of men and women in the first trimester
1, see B-ultrasound data: If the gestational sac is more than doubled in length and width, it is very likely that it is a male baby. The gestational sac is equal in length and width, so it is highly likely to be a female baby.
2, look at the shape of the gestational sac: like eggplant or long strips are more likely to be male babies, and round ones are more likely to be female babies.
Second, look at the second-trimester B-ultrasound single test for men and women.
In the second trimester B-ultrasound list, the value of biparietal diameter minus femoral length is greater than 2, which is more likely for male babies and less than 2 for female babies.
90% of these words are male treasures on the B-ultrasound list.
I had a big abnormal examination at 22 weeks of pregnancy, and the baby has been very cooperative. However, after the B-ultrasound came out, I said that the renal pelvis was separated, and I was scared out in a cold sweat. The doctor told me to closely observe the fetal movement and have another B-ultrasound examination at the age of 30.
When I got home, I still didn't feel at ease. I was afraid that my baby would have a little problem, so I went to the old expert and asked. The old expert said it might be a son. Boys like to hold their urine, and they will be fine after giving birth. He also told us that 90% of cases of renal pelvis separation are male babies. Call a friend, and the friend also said that this phenomenon will occur when pregnant. A friend gave birth to a son.
Then I checked some data. If the separation of renal pelvis does not exceed 10 mm, it belongs to the normal range. There is no problem when the fetus is less than 16 mm at birth. If it continues to increase, we should pay attention to it and review it regularly.
The words "separation of renal pelvis" are on the B-ultrasound list, and 90% of them are boys. However, it is also said that there is a 90% probability in dealing with specific things. Not all pregnant men have this problem. Please treat it with a normal heart. Let's talk about experience from personal experience. Most of the separation of renal pelvis is caused by the baby's urine, so pregnant mothers don't have to worry.
I forgot to mention that it is indeed a male treasure. Everything is normal and healthy. I hope that every baby can come to his parents safely and healthily, and I hope that sisters can get what they want whether they want male treasures or female treasures!
The most accurate way to see men and women through B-ultrasound.
B-ultrasound is one of the necessary examination items for women after pregnancy, which can help us understand the development of the fetus. However, when we first got the B-ultrasound list, we often looked blank because we didn't understand what the above data meant. Today, I will talk to you about the data of B-ultrasound.
B-ultrasound sheet
Generally speaking, the following nouns and data will appear on the B-ultrasound list:
BPF= biparietal diameter: refers to the longest part of the fetal head from left to right, which is one of the important indicators of whether a pregnant woman can give birth naturally, and can also be used to calculate the approximate weight of the fetus.
CRL= head-buttock length: it is the distance between the head and buttock of the fetus, indicating the longest axis measured parallel to the longitudinal axis of the carcass, and is mainly used to judge the gestational age of 7 ~ 12 weeks.
SP= spine: fetal spine can be seen after 12 weeks of pregnancy, but it can be clearly distinguished at 20 weeks of pregnancy. The fetal spine is continuous and normal, the defect is abnormal, and the spine may be deformed.
GS= gestational sac, also known as gestational sac: For women who have regular menstrual cramps for 28-30 days, after 35 days of menopause, gestational sac can be seen in the uterine cavity by B-ultrasound. Generally round, oval and transparent are normal.
FH= fetal head: normal contour, abnormal defect and deformation, normal midline without displacement and hydrocephalus.
FE= embryonic bud: early fetus. 6-7 months pregnant, embryo can be seen by B-ultrasound.
FL= Femoral length: refers to the length of thigh.
FM= fetal movement: fetal movement can be seen by B-ultrasound at 8-9 weeks of pregnancy. Strong is normal, weak may lead to fetal sleep or abnormality, which should be comprehensively analyzed in combination with other items.
H= Fetal heart: Fetal heart can be seen at the 7th-8th week of pregnancy and the 6th weekend of the earliest pregnancy by B-ultrasound. The normal frequency of fetal heart beat is between 120- 160 beats per minute.
Umbilical cord = umbilical cord: Under normal circumstances, umbilical cord should float in amniotic fluid. If you see the umbilical cord image in the fetal neck, it may be that the umbilical cord is around the neck.
PL= Placenta: Location refers to the position of the placenta on the uterine wall, and the thickness of the normal full-term placenta should be between 2.5 and 5 cm.
So what's the secret in the B-ultrasound list? It is said that the sex of a baby can be judged by the following. Let's have a look.
Look at the gestational sac: if the length and width of the gestational sac are more than doubled, it may be a boy, and vice versa. If the shape is round, it may be a girl, and the sharp or long one may be a boy.
Look at the fetal heart rate: boys may be below 140 beats/min, and girls may be above 140 beats/min.
Look at the biparietal diameter: if the biparietal diameter minus the femoral length is greater than 2, it may be a boy, otherwise it is a girl.

The baby boy's B-ultrasound is like this.
After pregnancy, many expectant mothers are keen to guess the sex of the fetus, and everyone has thought of various methods, such as looking at the sex through four-dimensional color Doppler ultrasound. Under normal circumstances, doctors will not disclose the sex of the fetus to you, but in fact, the photos of color Doppler ultrasound will reveal a lot of information. The following small series will tell you how to see the baby's gender from the B-ultrasound image.
