#Your first pregnancy, hope that the child in the stomach is a man or a woman#
On the birth of a child, there has been a lot of talk in the community, such as: sour children, spicy women, the Qing Palace table to measure the male and female, the month of the disease, the month to raise, give birth to a child dysmenorrhea will be good, give birth to a boy's nose will be bigger ......, and so on. These sayings that have been passed down from generation to generation by word of mouth are right or wrong, is there any scientific basis?
This issue, Dr sauce selected the more widely circulated, the higher degree of discussion of the 10, to give you one by one to reveal the secret. The first time I heard this, it was a very good idea to listen to it!
01
Sour children, hot women, accurate or not?
Of course not!
There is no research that clearly proves that taste preferences are related to the sex of the fetus, and that it's hormones that are responsible for the acidity or spiciness of the pregnancy, and that eating acid is not necessarily the best way to have a son!
The culprit behind the sour children is actually the change of stomach acid after pregnancy, women in pregnancy, the placenta will secrete HCG (human chorionic gonadotropin), it will inhibit the secretion of gastric acid, so that the gastric acid is reduced, gastric acid as a digestive an important material, it will affect the digestive function of the reduction, so pregnant women appeared to decline in appetite, and even nausea, vomiting.
In other words, if you want to eat something exciting and refreshing when you lose your appetite, you should be able to do so. So it's very normal to want to eat sour food and spicy food after pregnancy. As for why some people like to eat sour and others like to eat spicy, it all depends on personal preference.
02
Can you really tell if you're pregnant?
The Qing Gong Table is rumored to be based on the yin and yang, five elements of the Ideal Design, is a set of prediction of the birth of the Qing dynasty court doctors based on experience. The age at conception is the horizontal axis, and the month of conception is the vertical axis for predicting male and female births.
Although it is a "royal thing", but in fact, from the prediction principle analysis, the Qing dynasty table is still lack of scientific theoretical basis for support.
There has been a set of research data show:
Some people through the 107 cases of obstetrics research, to predict the male baby, for example, sensitivity = prediction of the sex of the male and the real number of cases with the real number of babies in the real gender for male x 100%; accuracy = prediction of the sex of the male and the real number of cases with the real number of cases with the real number of cases with the prediction of the sex of the male x 100%.
The overall precision and sensitivity was 40.19%. In terms of sensitivity, it was 44.44% for predicting males and 34.09% for predicting females, and in terms of precision, it was 49.12% for predicting males and 30.00% for predicting females. But for both men and women, the sensitivity and accuracy did not exceed 50%.
In Dr. Sauce's opinion, the Qing Gong table is a big data analysis table made by the Imperial Hospital, which has a certain statistical probability, but this probability is lower than that of blind guessing, so are you sure you want to take it seriously? If it is accurate, then the ancient court with all want to have a son of the ruthless, there should be no "princess" thing.
03
Is the birth of a child a cure for dysmenorrhea?
I guess many women have heard the theory that giving birth to a child will stop menstrual cramps. But what Dr Sauce wants to tell you is that this really varies from person to person.
Typically, dysmenorrhea can be categorized as primary dysmenorrhea and secondary dysmenorrhea based on the cause of the dysmenorrhea.
Primary dysmenorrhea is related to the position of the uterus, such as the uterus is excessively anterior or posteriorly tilted, or the endocervical opening is narrower, the menstrual blood and stripped endometrium can not pass through the cervical opening to flow out smoothly, which is one of the main causes of dysmenorrhea [2]. The passage of the fetus through the uterine opening during labor can play the role of dilatation, and after giving birth to the baby, menstrual blood and exfoliated endometrium can be easily discharged. This is why some of these women will be happy to find that their stomachs don't hurt during menstruation even after having a baby. But that's not to say that all pregnant women can be hit by this kind of luck and just solve the problem of menstrual cramps.
If primary dysmenorrhea can be cured by giving birth to a child, secondary dysmenorrhea is not this good luck. Because secondary dysmenorrhea is due to other gynecological diseases caused by a symptom, usually endometriosis adenomyosis, etc. [2]. The disease is not cured, the number of children does not help, the pain is still pain.
So, giving birth to a child is giving birth to a child, and there is no efficacy of curing the disease.
04
Monthly disease is not well, another one will be good?
Like the saying that giving birth can cure dysmenorrhea, another saying that thinks that giving birth can cure diseases is that "the disease of the month, the month to raise", "the disease of the month is not well, and then a new one to sit in the month, it will be fine". The fact is that this is really the case?
From the perspective of Chinese medicine, "moon disease" is there, Chinese medicine believes that, in general, people's bones are closed, the process of childbirth so that the whole body of the mother's bones open, this time if you do not pay attention to, such as shampooing, bathing, eating cold food will allow the wind and cold to take advantage of the situation, through the open bones into the maternal body until the end of the month, the bones will be closed, and then the body of the mother's body, and then the body of the mother's body. At the end of the month, the bones closed, the wind will be locked in the body, which left the "moon disease".
And the " month disease month cure " of this statement, Dr. Sauce think is a misunderstanding of the misinterpretation, if it is said that the month of the disease should be treated in a timely manner, can not be delayed, from the meaning of this understanding, this sentence is also correct. However, if it means that diseases acquired in the month can only be cured in the month, after the period of the month can no longer be cured, or that they can only be cured in the next month, this statement is not correct. This is not true, because usually the disease, as long as the diagnosis is correct, to find the cause of the disease, the treatment of the right symptoms, can always be cured. The idea that you can't be cured after the first day of the month is not scientifically valid.
05
Can the sex of the fetus be reversed?
There are a lot of sayings circulating in the folklore that as long as the fetus is not yet born, the gender can be changed when it is in the mother's womb, and there are even a lot of remedies to help pregnant women change the gender of the fetus.
In many pregnancy preparation and parenting APPs, there are a lot of transactions of "fetal transfer medicine", claiming that "the pregnant woman is guaranteed to transfer the fetus within 40 days of pregnancy", "the birth of a son is guaranteed, and a full refund is not allowed", "the birth of a son is guaranteed", "the birth of a son is guaranteed", and "the birth of a son is guaranteed". "," "male or female, control at will, after the birth of the child charges" ...... This is 2021, actually really many pregnant women are willing to spend money to do this kind of transaction, Dr. sauce is really shocked!
The biology class should know that the sex of the fetus in the moment he became a fertilized egg has been decided, there is no drug or means to intervene and change the sex of the fetus.
And there have been many reports that the so-called "fetal transfer pills" are of unknown origin, which may not only cause harm to the pregnant woman's body, but also lead to the baby's organ damage, intellectual impairment, deformities, and other problems.

Is it possible to have a daughter if your father is smart?
More than once I have heard this argument: if the father is smart, it is easy to have a daughter. The first thing you need to do is to look at the way that you are using the Internet, and you can see that you are using the Internet to get to know the people you are talking to. Even the "God counts" Huang Lei is also Mr. two daughters it ......
Such a statement in the end there is no scientific basis? The science says: I have no evidence that parental IQ affects the sex of the child. I'm not going to take the blame for that!
Biology tells us that the combination of chromosomes of the mother and father determines the sex of the baby, if the father's chromosome is Y, and the mother's egg combination is born son; if the father's chromosome is X, and the mother's egg combination is born girl.
Although genetic influence on IQ is about 50-60%, there is no evidence that IQ also determines gender. It's just a matter of probability that dads are smart enough to have daughters, and if that's the case, it's just pure coincidence.
07
Belly pointed, have a boy?
China's folklore has been circulating in the pregnancy belly pointed easy to give birth to a boy, the belly round easy to give birth to a girl said. And foreigners also have a different superstition on this kind of problem, like if the pregnant woman's stomach protrudes forward like a large tennis ball, it may be a boy, and if the weight of the stomach is more evenly distributed, it may be a girl. Is this really true?
In fact, having a boy or a girl does not have much to do with the roundness and sharpness of the pregnant mother's belly, the reason why the pregnant mother's belly is different is because it is related to the size of the fetus, the fetal position, and the pregnant mother's body type.
The position of the fetus baby in the mother's uterus also affects the shape of the belly, for example, if the fetus baby is facing the mother, the belly will look flat, and if the back is facing the mother and puckers up, of course, it will be more protruding. In addition, you imagine, a thin pregnant mother, when the fetus continues to develop and grow, the belly lateral development of no space, is not only forward "pointed" to grow it.
So, relying on the shape of the belly to judge men and women is not based on any scientific evidence. However, the shape of the mother's stomach, most of the obstetricians will be used as a basis for visual inspection of the mother is not difficult to determine the existence of the judgment.
08
What's the difference between a boy and a girl?
In addition to looking at the belly to identify men and women, it is said to look at the skin can also identify men and women, if the pregnant mother pregnant acne, spots, skin becomes rough is a boy, if the pregnant mother's skin becomes smooth and delicate is a girl. Dr Sauce always feels that there is something wrong with this kind of argument! What about the twins? The first thing you need to do is to get your hands dirty.
In fact, compared to the pre-pregnancy, the hormone levels in the mother's body will change significantly, estrogen, progesterone, testosterone will rise significantly. Some statistics show that near the time of delivery, the level of estradiol (the most biologically active estrogen) in the body of a mother carrying a girl is about 23,000 ng/L, and that of a mother carrying a boy is about 20,000 ng/L. In a normal adult woman, with the menstrual cycle, the level of estradiol in the blood is 20 ng/L-750 ng/L.
By this account But in fact, whether the skin of the mothers-to-be can remain bright and beautiful, not only depends on the level of estrogen, but also with living habits, the environment and many other factors. The first thing you need to do is to look at the skin of a pregnant woman to determine the sex of her baby.

Is it possible to have a baby boy if your nose gets bigger while you're pregnant?
I remember when Hong Kong star Anna Wu gave birth to her second child, she posted a microblog lamenting: why does my nose get bigger when I'm pregnant and others don't? Once caused the public discussion, have said: pregnant nose is bigger, and will have a boy.
Dr. Sauce can't help but wonder why some people's noses get bigger when they're pregnant. Is it really related to the sex of the fetus?
In fact, it is not, the doctor's point of view: pregnant women's noses become bigger to give birth to a boy, this is just a folk saying, there is no scientific basis. The first thing you need to know is that the sex of the fetus is determined by the combination of the chromosomes of the two parents.
And during pregnancy, the nose nose will have a bigger phenomenon, because after pregnancy, the body's hormone level changes caused by the pregnant woman's body after the increase in estrogen, will lead to some parts of the body edema, such as can lead to the nose head of the soft tissue swelling, will lead to the nose, the nose is bigger, the nose is rounded, bigger. It is possible that the nose may also shrink as hormone levels change after the birth of a child.

Pregnant mothers eat rabbit meat, the child will hare lip?
In addition to some of the rumors about the birth of a boy or girl that make people laugh and cry, the old generation of pregnant mothers also have a lot of taboos on the "food". For example, pregnant can not eat rabbit, or the child will be "hare lip".
I have to say, to eat rabbit meat and hare lip link, this is completely on the hare lip mechanism of misunderstanding, but also on the pregnant woman health food rabbit misinterpretation.
"hare lip" medically called cleft lip, belonging to the congenital facial deformities, an average of about 1,000 babies in 1 with cleft lip and palate. This congenital deformity is caused by some kind of disease factor during the early pregnancy of pregnant women. Current medical opinion is that the possible causative factors are:
? Genetic factors: About 20% of children with cleft lip and palate have an occasional family history of the disease;
? Infectious factors: early pregnancy when the mother has had a viral infection, such as influenza, rubella or some kind of injury;
? Nutritional factors: vomiting and partiality during pregnancy, resulting in vitamin A, E and trace element deficiencies;
? Inappropriate use of medication: having taken certain sedative, anti-allergy and anti-epileptic drugs;
? X-ray radiation: the mother was exposed to a lot of X-rays during pregnancy.
The above factors have nothing to do with eating or not eating rabbit meat, on the contrary, rabbit meat is a good tonic during pregnancy, every 100 grams of rabbit meat contains about 1600 mg of lecithin, lecithin is an important element indispensable to the development of the brain and nerves, which is conducive to the development of the fetus's brain, and has a brain-boosting and intellectual role.
