The gestational sac is round. Must it be a girl? Rumor: You can tell men and women by the shape of gestational sac!

1 If the gestational sac is round, it must be a girl. If the gestational sac is round, it may not be a girl.

There is a saying on the internet that you can know whether the baby is a boy or a girl by looking at the shape of the gestational sac. Specifically, if the gestational sac is eggplant-shaped or long, it is more likely to be pregnant with a male baby. If the gestational sac is oval or round, it is likely to be a female baby. But these statements have no scientific basis and are not credible.

Why gestational sac is round is not necessarily a girl, because judging men and women according to gestational sac is actually an incorrect reference.

The size and shape of gestational sac measured in medicine can only be used to judge whether the baby in the uterus is developing healthily, and estimating the approximate gestational age has no effect on judging whether the baby is male or female.

In addition, the round, size and length of the gestational sac will gradually change with the baby's development, but the baby's sex is determined from the moment of pregnancy. It is conceivable that it is totally unreliable to judge whether a baby is male or female only by gestational sac data.

3 rumors: are the tricks on the internet that argue about fetal men and women reliable? 1. Look at the gestational sac data: It is not reliable to say that there must be three data on the B-ultrasound list. For example, the data of the third gestational sac is twice as small as the first two, and it must be a son. If the third data of gestational sac is decreasing compared with the first two data, it is the daughter.

For example: 4.0cm*3.8cm* 1.9cm is the standard male treasure; And 4.0cm*3.3cm*2.7cm is the female treasure.

2, look at the Tang sieve data: it is said that the Tang sieve data of pregnant women is not reliable. If the mom value of AFP is greater than 1 and the mom value of hcg is less than 0.5, it is a boy; When the mom value of AFP is less than 1 and the mom value of hcg is greater than 1, it is a girl; When the HCG value is between 0.5- 1, the AFP of boys is greater than 1 and that of girls is less than 1. But this data can't be used to judge the baby's sex, just for entertainment.

3, look at the B-ultrasound biparietal diameter and femoral length: unreliable biparietal diameter is the transverse diameter of the fetal head, and femoral length is the length of the fetal femur. This data can only detect the baby's physical development, but can't detect whether it is male or female. It is said that boys have shorter heads and thighs, that is, biparietal diameter-femur length >; 2, the conclusion that the head-leg difference is small is a girl, which is not reliable.

4, male and female test paper, similar to pregnancy test paper: unreliable This test paper is based on the urine of pregnant mothers. The result is that the blue line is a male treasure and the red line is a female treasure. I don't know if this is the acid-base component in urine or something, but the measured results are for entertainment only and the accuracy is not very reliable.

5, fortune teller: it is not reliable to find a master who takes care of life to test whether the baby is male or female. It is estimated that parents usually have the habit of fortune telling. This is definitely inappropriate and unreliable, and there is no way to discuss money. The accuracy of seeing men and women is high, and people will not pay. After all, there is a 50% accuracy rate. Whether it's a man or a woman, you do the math yourself.

6, Chinese medicine pulse: unreliable some tricks, saying that you can know whether it is a man or a woman by measuring your own pulse. If the left hand pulse is a boy and the right hand pulse is a girl. This trick, I believe you are very smart, you can't see it at a glance. I will exercise more, and my pulse will get better soon!

7. Look at the shape of the pregnant mother's stomach: you can see men and women without relying on your mother's stomach. This statement is: if the belly is round, it is a girl, and the belly is pointed, it is a boy; Another way of saying it is that if the pregnant woman is a girl, if the pregnant woman is a boy, but the pregnant woman's stomach is round or not, it may be most related to how much the pregnant woman has gained weight, so it is not reliable.

8, look at the midline of pregnancy: unreliable after pregnancy, there will be a black line in the middle of the expectant mother's stomach, called the midline of pregnancy. It is said that the darker this line is, the higher the chance of having a boy.

But in fact, the color of the midline in pregnancy is influenced by hormones in the body. During pregnancy, the levels of progesterone and hormones that stimulate melanocytes increase, which causes the originally black part of the body to become darker and will recover quickly after giving birth. This phenomenon has nothing to do with the sex of the fetus.

9. See if pregnant mothers become beautiful and ugly during pregnancy: It is not reliable to say that many mothers will become ugly after pregnancy, but some mothers have not changed much except being fat. Many people judge whether the baby is male or female according to these differences. For example, after pregnancy, the skin becomes darker and darker, a lot of chloasma grows on the face, and the pores become thicker. That's a boy, because:

If the expectant mother is pregnant with a female baby, the endocrine system of the female baby is the same as that of the expectant mother, and the estrogen secreted is dominant, which is equivalent to the expectant mother eating estrogen, and the skin will naturally get better and better; If you are pregnant with a baby boy, male hormones are dominant in the endocrine system of the baby boy. The increase of male hormones means that the pores of expectant mothers will increase and the skin will become rough. However, although this statement is very popular, unfortunately, there is no relevant research result to prove it.

in fact

Whether the expectant mother's skin can keep bright depends not only on the hormone level in the body, but also on factors such as diet, sleep and mood. Many mothers are pregnant, so they will pay attention to health in their lifestyle, avoid spicy food, go to bed on time before 10, be cared for by their families, have a nutritious diet and be in a good mood, so the skin and state of expectant mothers will naturally be better. Aren't these the usual maintenance methods for women?

10, Blood test in Hong Kong or abroad: It depends, so many things are not very reliable, but I suggest you collect your mother's blood online and send it to Hong Kong or abroad for testing. If you are insured in a regular hospital, it should be more reliable, but if it is a small place, it will be irregular. Maybe I will give you a random test and give you a result. After all, the accuracy is 50%. Even if it is not allowed, the loss will not be great.

If you want to know whether the baby is male or female, I'll give you a trick 1. When expectant mothers are more than 16 weeks pregnant, they will have a B-ultrasound. At this time, you can observe the baby's reproductive organs by doing B-ultrasound.

2, and then through the observation of B-ultrasound doctors, it is the most accurate to judge the external genitalia of the fetus.

comment

In China, it is forbidden to do fetal sex identification, so even if the pregnant mother meets the above conditions, it is impossible to know the sex of the baby. But you can know whether the baby is male or female by indirectly consulting your B-ultrasound doctor, such as:

(1) Ask the doctor, can the baby wear a skirt? Answer: Yes, it is a female treasure, on the contrary, it is a male treasure.

(2) Ask the doctor, I gave the baby two names, what is the name of the female baby and what is the name of the male baby?

(3) There are too many places for boys to spend money now, and they have to buy a house after giving birth to a boy. Do you want to buy a house now?

(4) I want to decorate my baby's room with pink or blue decoration recently. Pink stands for women's bags and blue stands for men's treasures.

(5) There is a Construction Bank at home. I wonder if this is China Construction Bank or China Merchants Bank? CCB is a male treasure, and China Merchants Bank is a female treasure.

Tip: You can refer to the above questions to test the doctor's answer. Generally, many doctors will give you indirect hints. But remember not to ask the doctor at close range, and don't give the doctor a red envelope for an answer. None of this is desirable.
