During pregnancy, mothers-to-be are always obsessed with predicting the sex of their babies, because the state regulations say that asking the doctor directly will not yield any results, of course.
So, many parents-to-be began to turn to folk experts and the Internet, so today I heard that the tip of the belly to give birth to male, round belly to give birth to female; tomorrow I heard that the gestation line is left or in the birth of boys, and vice versa for girls; and then two days after hearing directly from the ultrasound sheet can see the birth of male and female say …… pregnant mothers play is not happy! The actual fact is that you can find a lot of people who are not able to get a good deal on the subject.
Take the question “Is it true that you can tell if you are having a baby from the ultrasound sheet?” This question, the last few years several crazy sayings are.
The shape: like an eggplant or a long strip is more likely to be a male baby, round is more likely to be a female baby.
Look at the data: according to the data on the ultrasound sheet, if the difference between the length and width is more than double the likelihood of male babies. A female baby is more likely to be equal in length and width.
5W+6D. 25mm*11mm gestational sac is a boy;
7W+1D. 2.9*1.9 gestational sac is a boy;
9W+4D. 46.6*30.2mm gestational sac is seen in the uterus, which indicates that twin girls are being carried in the uterus;
46 days BC data. Gestational sac 20*17*17 is a girl;
Many pregnant mothers have seen more of these “technical posts” and have taken their own ultrasound sheets and looked at them against each other. If they are right, they may choose to believe them and be happy! Some of them are also half-hearted to consult in the background.
The actual truth is, every time I see this, my heart is actually refusing to answer, because I really can’t do ah! Although the author extremely do not want to let you down, but also do not want to spread pseudoscience! So, if you have to take the ultrasound sheet to ask whether it is a boy or a girl, I can only answer you: the ultrasound results of the normal birth of the fetus, is not able to determine the sex of the fetus. Because, at present, ultrasound can only determine male and female based on the fetal genitalia, and the gestational sac and the size of the sac are not directly related to the sex of the baby. The size and shape of the gestational sac, for example, is influenced by many factors. For example, if the ultrasound probe is perpendicular to the uterine plane, the gestational sac will be round; if the ultrasound probe has a certain angle of inclination to the uterine plane, the gestational sac will be long.
The doctor will not describe the sex of the fetus in writing, nor will he or she take pictures of the fetus’ vulva. Therefore, it is naturally impossible for us to determine the sex of the fetus from such a test result and tell you. So, get it?! It is not scientific to tell male and female only by the shape and size of the gestational sac, so do not blindly believe and follow it.
However, the data on the ultrasound sheet is indeed very important, where each indicator reflects the basic condition of the fetus, and the doctor also judges the development and health index of the fetus based on these data.
1.BPD：Biparietal diameter
Explanation: It refers to the widest length between the left and right sides of the baby’s head, also known as the “large transverse head diameter”. BPD is generally used to determine the weight and development of the fetus, as well as the possibility of a normal delivery.
Analysis: If it is large, the fetus needs to be checked for hydrocephalus. If it is small, it should also be checked. If there is no abnormality, there is no need to worry too much, usually pay attention to strengthen nutrition, eat more high-protein food, and do regular medical checkups.
2.CRL: top-rump length
Explanation: It refers to the distance between the top of the fetus’ head and the outer edge of the buttocks, also known as the top-rump diameter and the head-rump distance.
Analysis: The top-rump length can be used in early pregnancy to estimate the gestational age, and is most accurately measured between 7 and 12 weeks of pregnancy.
3.HC：Head circumference
Explanation: It refers to the maximum circumference of the fetal baby’s head from the face to the back of the head.
Analysis: The main purpose of measuring head circumference is to determine the development of the baby. It is closely related to the biparietal diameter, the biparietal diameter is long, the head circumference is large; the biparietal diameter is short, the head circumference is small. If the head circumference data is normal, it means that the fetal baby is developing well and it is easy to deliver the baby smoothly.
4.AC：Abdominal circumference
Explanation: Abdominal circumference refers to the length of the fetal baby’s stomach in one week. It is usually used together with the anterior-posterior abdominal diameter (APTD) and transverse abdominal diameter (TTD) to predict the development of the fetal baby.
Analysis: If the abdominal circumference is large during ultrasound, it needs to be considered that the fetus has fluid in the belly or obesity caused by over nutrition; if the abdominal circumference is small, it proves that the fetus is thin, with low resistance and poor ability to adapt to the ring.
5.FL：Femur length
Explanation: Femur length is the length of the bone between the root of the thigh and the knee of the fetus, which is used to project the weight of the baby together with BPD.
Analysis: The normal value of femur length should usually differ from the value of biparietal diameter in the same month by 2-3 cm. Generally speaking, after 30 weeks of pregnancy, the test values within the upper and lower two weeks of the reference value are normal.
6.H：Fetal heartbeat
Explanation: It refers to the frequency of fetal heartbeat, which is an important criterion to reflect the health of the fetus.
Analysis: The normal fetal heart rate is between 110-160 beats per minute. If the fetal heart rate lasts for more than 10 minutes is less than 110 beats per minute or more than 160 beats per minute, it indicates that the fetal heart rate is abnormal. The abnormal fetal heart rate usually means the fetus is lacking oxygen in the uterus and needs to be treated with intervention.
7.AFI: Amniotic fluid index
Explanation: The amniotic fluid index and the vertical amniotic fluid depth of the maximum amniotic pool are one of the two important indicators to reflect how much amniotic fluid is present.
Analysis: When doing ultrasound, the center of the umbilicus of the pregnant woman is divided into four areas: upper, lower, left and right. The amniotic fluid depth of the four areas is added together to obtain the amniotic fluid index, and the normal value of the amniotic fluid index in late pregnancy is 8-18 cm.
If the amniotic fluid index is greater than 24 cm, the diagnosis is too much amniotic fluid; if the amniotic fluid index is between 8-24 cm, the diagnosis is normal amniotic fluid; if the amniotic fluid index is less than 8 cm, the diagnosis is too little amniotic fluid. Too much and too little is not good for the fetal baby.
8.GP: Placenta grading
Explanation: Starting from late pregnancy (28 gestational weeks), placenta grading will appear on the ultrasound report sheet. Generally the placenta is divided into 0, I, II, III, and sometimes III+.
Analysis.
Grade I marks the basic maturity of the placenta;
Grade II late indicates that the placenta is mature;
The placenta is senile due to calcification and fibrin deposition, which reduces the placenta’s ability to transport oxygen and nutrients and puts the fetus at risk.
