Can four-dimensional color Doppler ultrasound see the sex of the fetus?

Nowadays, women need to do a lot of tests after pregnancy. Thinking color Doppler ultrasound is an examination that modern pregnant women will do during pregnancy. Many people know that you can clearly see the baby's gender through thinking color ultrasound. So can four-dimensional color Doppler ultrasound see the sex of the fetus? What are the methods to check the baby's sex?

Can four-dimensional color Doppler ultrasound see the sex of the fetus? If you look at gender through four-dimensional color Doppler ultrasound, you will generally not see it without training. If you see the image in time, you may make a mistake. Therefore, an experienced doctor is needed to see it, so the accuracy is higher. However, because the country prohibits sex testing, doctors will not tell you the results. In this way, some people say that gender can also be seen through the data of four-dimensional color Doppler ultrasound.

1, which will be printed on the color Doppler list. There are two lines on the far right of the head, which are composed of English letters and numbers. The first line is the date and the second line is the time. If the first line starts with m, it is male, if it starts with f, it is female, and the second line starts with t, which means time.

2. There are usually "bilateral renal pelvis separation" on the color Doppler ultrasound list, and 90% of them are boys; If it is "no obvious separation of bilateral renal pelvis", then 95% are girls.

3. The small English letters Qual high 1 on the color ultrasound list are girls and 2 are boys.

4. Look at the sex of the fetus through four-dimensional color ultrasound. Six months later, take a four-dimensional color Doppler ultrasound. As long as the baby's posture is positive, it is not to give a back, but to know whether it is a man or a woman. However, because the country expressly stipulates that the sex of the fetus cannot be checked, the doctor will not show the mother the side that can clearly see the sex.

Three white lines are the obvious characteristics of female treasures. If you don't see three obvious white lines, you can see if there is anything protruding between your legs with a small groove in the middle. This is a female treasure.

Tip: Look at men and women through four-dimensional color Doppler ultrasound, preferably after 15 weeks of pregnancy. Because before 12 weeks of pregnancy, the reproductive organs of male treasure and female treasure look the same, both of which are small buds. After 12 weeks, they begin to develop differently. The baby girl's bud will develop independently in the body, while the baby boy will start to develop into a small penis. And this series of development, until 15 weeks later, can be clearly identified by four-dimensional color Doppler ultrasound, so it is too early to see the gender by four-dimensional color Doppler ultrasound.

How to treat the sex of the fetus After pregnancy, many expectant mothers find it difficult to conceal their curiosity about the sex of the fetus. They can predict the sex of the fetus by looking at the fetal heart rate, B-ultrasound data and the past years, but the accuracy of these methods has not been scientifically verified and is for reference only.

Fetal heart rate depends on men and women.

There is a folk saying that if the fetal heart rate is lower than 140 beats/min, the fetus is a boy. Generally speaking, the heart rate of girls is higher than that of boys, but this has nothing to do with the sex of the fetus.

The normal heart rate of the fetus is between 120 beats/min and 160 beats/min. Experts point out that listening to fetal heart needs special instruments. You can listen to fetal heart with a Doppler stethoscope in very quiet conditions around 12 weeks of pregnancy. We advise expectant mothers to go to the hospital or use fetal language instruments at home. The mobile phone software of fetal language instrument also has the function of gender test.

1, the longer the preparation time before pregnancy, the easier it is to have a boy. Luc Smith, an epidemiologist at Maastricht University in the Netherlands, led the researchers to investigate 5283 women who had given birth, and found that 498 of them were pregnant for more than one year, and the proportion of boys was 58%. The probability of a woman giving birth to a boy within one year of pregnancy is 5 1%.

2. By calculating the expected date of birth, that is, the sum of the pregnant mother's age (imaginary age) and the expected date of birth (lunar calendar), if the mantissa is odd, it is a male baby, and if the mantissa is even, it is a female baby; B-ultrasound scanning can generally identify the sex of the fetus at 16 weeks. This detection method mainly depends on the reproductive organs of the fetus, so it is directly related to the position of the fetus and the experience of doctors. Clinically, the accuracy rate of male infants can reach over 95%, while that of female infants is only about 85%.

3, palm print, pregnant mother's right hand gently clenched fist, look at the little finger side of the fist, the position of the daughter line, the daughter line is deeper and thicker, indicating the male treasure; The map of the Qing Dynasty consists of two parts, the abscissa is the month of pregnancy, from 1 to 12, and the ordinate is the age, from 18 to 45. Many people ask how to read the map of the Qing dynasty, and the focus is on these two parts. The age of women is calculated according to the imaginary age of the lunar calendar (that is, the real age plus 1). Example: the year of birth is 1985, the year of 20 10 is 26 years old, the new calendar of pregnancy month is 65438+ 10/5, and the lunar calendar is 65438+ the eighth day of February.

I believe everyone will understand how to treat this pregnancy after reading the information I introduced. However, I still want to advise all expectant mothers not to have boys and girls, but to put the baby's health first, so as to have a harmonious family.
