According to the current level of medical science and technology, the birth of boys and girls can of course be artificially controlled, but this person, not the husband and wife, but the reproductive center medical workers.

First, there is currently no reliable method in the world that allows couples to control the birth of a boy or a girl on their own.

With the rapid growth of the internet, a lot of information, correct or incorrect, has been spreading rapidly. The more attention it gets, the more it spreads.

Our country, since ancient times, the idea of son preference is very serious, although there has been some improvement over the years, but in many poor and backward places, the birth of a boy is still the top priority. Clinical work in obstetrics and gynecology, will find that many women over the third and fourth birth, needless to say, the front must be born are girls.

Because many people want to control the gender of their children, corresponding methods have become popular.

For example, the most popular claim is that an alkaline body can give birth to a boy. The body's acid-base is in dynamic balance, with a ph value between 7.35 and 7.45; below 7.35 is acidosis and above 7.45 alkalosis, requiring medical intervention, not to mention having a baby!

If you want to let yourself in the so-called "alkaline body", the little superhero can teach you a simple method, keep exhaling, resulting in a reduction of carbon dioxide in the body, you can cause "respiratory alkalosis", but you can tell you, this can not give birth to a boy, but also may be sent to the hospital. I'm not sure if I'm going to be able to do that.

Another theory is that sperm with x chromosomes survive longer and sperm with y chromosomes move faster.

If you want to have a boy, you should have intercourse after ovulation, and the y chromosome, which is fast, will have the priority to meet and combine with the egg; if you want to have a girl, you should have intercourse before ovulation, and the x chromosome, which has a good endurance, will be able to wait for the egg and combine with the egg.

This statement is respected by very many people, and includes some obstetricians and gynecologists, and a former sister shared with me that she had intercourse after ovulation and got pregnant with a son. Later, when the second child was born, she wanted a daughter, but the result was still a son. I can see that this kind of argument is also not reliable.

Secondly, although medical practitioners, have the ability to control the birth of boys and girls, they should not abuse this ability.

Reproductive centers do have the ability to identify the sex of embryos before they are transferred, but medical staff do not have that power, otherwise the consequences of the resulting serious population dislocation would be unimaginable.

Ultrasonographers in obstetrics and gynecology can also find out whether a boy or a girl is being carried in mid-pregnancy, but again, it is forbidden to tell the pregnant woman or her family. In fact, in many developed countries, pregnant women are allowed to know the sex of the fetus in advance, because it will not affect the fate of the fetus in the womb. But in our country, it is not allowed to operate in this way!

Of course there are special cases where sex selection is possible in order to achieve eugenics. The premise is that the couple carries sex chromosome disease-causing genes, and the resulting boy or girl may carry the disease-causing genes, thus affecting the quality of the fetus's survival, so this requires preimplantation sex diagnosis, which is legal.

No matter how much the little superhero emphasizes that having boys and girls is the same, I believe that there will still be a lot of patriarchy, which is not only caused by the personal wishes of the couple, but also by the public opinion environment and lack of education in the whole society.

What we can do is to try to protect women's rights, improve the environment for girls to grow up in, and teach them to protect themselves and love themselves. This is the meaning of the little superhero science, ❤.

The probability of having a boy or a girl is the same in everyday situations, which is determined by our body's geneticsOf course, with the advancement of medical technology, it is possible for modern medicine to achieve reproductive sex selection. Of course, with the advancement of medical technology, modern medicine is capable of reproductive sex selection, but it certainly will not be allowed to be used for the selection of pure reproductive preferences, but only for the avoidance of specific single-sex genetic diseases. However, it is important to realize thatGender is definitely not determined by what you eat, what medications and remedies you use, and I hope that you will keep your eyes peeled to avoid being deceived!。Humans of both sexes have 23 pairs of 46 chromosomes that carry all our genetic material, which of course includes1 pair of 2 sex chromosomes that determine gender, XY for males and XX for females, a fertilized egg is formed when a male sperm (containing half of the male chromosomes and either X or Y sex chromosomes) combines with a female egg (containing half of the female chromosomes and only Y sex chromosomes).The sex of a fertilized egg is determined by the combination of its chromosomes, e.g., if the sperm carries X, it is female, and if it carries Y, it is male, and the probability of this is the same in nature.。From the above, I believe we all know how the sex is determined, so that the only way to determine the sex by human intervention is to select the sperm that combines with the woman's egg, which is of course achievable by modern techniques such as in vitro fertilization (IVF), which are highly demanding and also legally binding, and which are unlikely to be used in the general population.Only used in the treatment of single-sex genetic diseases (a disease that occurs only in males or females and can be avoided by sex selection).。I hope that you will correct your understanding.All boys and girls are the same. It's a natural choice. Don't force it too much.. Don't believe outside rumors so you can avoid being fooled.

In the past two days, an advertisement pushed on an e-commerce platform caused a heated discussion among netizens. The advertisement reads:

What if I have a daughter? Use Alkaline X-Power for the second child!

Image Source: Internet

The slogan was particularly loud, but in less than half a day, this product was revealed to have no relevant approvals, and the platform side also urgently withdrew the advertisement.

In fact, apart from this outbreak of Alkaline X-Positive, there have been all sorts of strange and weird products and recipes circulating on the Internet that claim to help the birth of a boy or a girl, such as calculating the chart of the uterus, eating alkaline food, adopting special body positions, and so on.

Are these methods reliable?

The most authoritative international medical secondary database "UpToDate" points out that no matter whether it is food, counting, special techniques ...... these methods, all can not affect the sex of the baby.

Could it be that, with all the advances in medicine nowadays, there is really no way out?

Ways to control the birth of a boy or a girlThere's only one.

That would be the third generation IVF technique.

To be precise, it should be one of the third-generation IVF techniques called "Techniques for preimplantation sex selection" (胚胎預植入前的性别选择技术).

Why is it useful?

In general, everyone has 23 pairs of chromosomes, including a pair of sex chromosomes that determine our gender:

Girls are XX and boys are XY.

A girl contributes an X and a boy contributes an X or Y. When they meet (fertilization), if the combination is "XX", the pregnancy is a girl; if the combination is "XY", it is a boy.

The moment a fertilized egg is formed, whether it is male or female is decided.Naturally, the ratio of male to female babies is 106:100, which is approximately 50/50.

Third-generation IVF technology, which can在Prior to the formation of a fertilized egg, sperm and eggs carrying the appropriate chromosomes are artificially selected and cultured to form a fertilized egg under in vitro laboratory conditions before being implanted into the pregnant mother's uterus.

But!

This technology was not developed to be used to control the birth of boys and girls, but ......

science and technologyIt's for saving lives.

This technology was originally created to avoid hereditary diseases in newborns through sex selection.

For example, in the case of certain diseases, if a boy is born, this child will suffer from the same disease as his parents, but if a girl is born, she will be healthy. It is only at this point that the choice to have a healthy girl is made for medical reasons.

As a result, the use of this technology is severely restricted.

Major medical societies in Europe and the United States, including the American College of Obstetricians and Gynecologists (ACOG), the Human Fertility and Embryology Authority (HFEA) in the United Kingdom, and the European Society of Human Reproduction (ESHRE), have explicitly requested that theThis technique of sex selection can only be used for the treatment of certain genetic diseases and not for sex selection for non-medical purposes.

The Measures for the Administration of Assisted Human Reproductive Technology issued by the Ministry of Health of China also clearly stipulate that.Medical personnel shall not practise sex selection that is not medically necessary.

In short, this sex selection technique is designed to help give birth to a healthy life.

And whether to have a boy or a girl is a hopeless additional choice.

give birth to a boy or girlIs it really the same in China?

This outbreak of the 'baby boy pill' incident is scientifically absurd, but the reason behind this is well known to us.

In order to satisfy their own preference for the gender of their children, there will still be people who count the charts of the womb, people who believe in the acid-alkaline constitution, and people who pray to the gods and Buddha ......

Some people are having one after the other, and there are even people ......

The NBP had summarized data from the national census to create a set of pictures. The results were frightening:

Generally speaking, the normal natural birth rate of men and women should be around 106:100, however, the sex ratio of men and women at birth is higher than that in many places, and even exceeds 120:100 in some places.

And the situation is even scarier with second and third children:

Photo credit: NKP

In some places, the male-to-female sex ratio for second and third births can even exceed 160:100.

Who, and by what right, decides the sex of the child?

Perhaps the outbreak of the "boy pill" incident will soon die down. But gender selection is a complex issue that involves human rights, medicine, ethics and gender equality in many ways.

This is a problem that will probably always be there.

Choosing a gender for the sake of the child's health is a sign of respect for life;

Choosing a gender to fulfill a personal preference is a travesty of life.

What do you think about "alkaline body can give birth to a son"? From a scientific point of view, can the birth of a boy or a girl be controlled artificially?

Wukong's little secretary is really messy, to get this question, toad jumped into the well - do not understand, but people are not born to know, do not understand to ask well, asked a dry obstetrics and gynecology students, to get the general, recorded in this, is to complete the homework, the connoisseurs, please criticize.

Junior high school chemistry began to learn the acid-base problem, human blood, with a PH test paper a measure, days, there is also a difference between acidity and alkalinity it. General human blood PH value between 7.35-7.45, showing a weak alkaline, which is the best pH. We drink water, and many of us like to drink weakly alkaline water, just to keep the body's pH at the optimal scale. We caution others to eat less big fish and meat, it is for the human body pH problem, big fish and meat is acidic.

This means that the pH of the body can change due to factors such as diet, or lifestyle habits. Once measured, many people show weak acidity. A small number of people maintain it well and remain weakly alkaline. It has been noted that keeping the body slightly alkaline can prevent diseases.

After studying the issue of acid-alkaline physique, we return to the issue of having children. Eugenics, eugenics, eugenics, eugenics, one of the three is indispensable, and it is not outrageous to study and research eugenics.

If a woman presents a weakly alkaline body, it means that the woman is in good health, endocrine stability and youthfulness. That is to say, the fertility base is good. Besides, the male who decides whether to have a boy or a girl, scatters out a piece of X and Y to get involved with the X of the female; if X meets X, a girl will be born, and if Y meets X, a boy will be born. According to in vitro experiments, Y in a weakly alkaline environment, vitality will be enhanced, he first snatched the possibility of the return of a good man, because it is in vitro experiments, the body environment is more complex, it is difficult to conclude, but that is to say that the legend is a certain amount of truth. But it is not a scientific conclusion.

The society has developed, men and women are the same, but eugenics has always been important, for eugenics, for health, maintaining an alkaline body is still a must. How to maintain an alkaline body? Healthy diet, good work and rest habits, maintain psychological balance, reasonable diet and moderate exercise.

I don't know what kind of person made up the idea that an alkaline body can give birth to a son. In fact, the birth of a boy or a girl is really not man-made to eat something can control, can have a son or not depends on the male sperm.

If you want to have a son, you really can't just change your pH or drink a few tonics and be successful. The birth of a child is determined by the genes in the body. When the man provides X sperms, a daughter is born; when the man provides Y sperms, a son is born.

We can not be man-made to change the gene, so people who want to change the body to have children or wash sleep. Such a statement is completely unscientific, the human blood pH value is not because of the food eaten into the change, the blood pH value is usually maintained between 7.35 ~ 7.45, not in this range is sick.

Although it is not possible to decide the sex of a boy or girl, we can strive for eugenics. During the preparation period, the woman can take folic acid to prevent neural tube defects in the baby. For the man, he can go for a semen test to check the viability of his sperms and try to have good quality sperms. Couples try not to stay up late, eat more high-protein food, moderate exercise, and strive to give birth to a child with a good body.

Let me start by saying this.Sex selection for non-medical reasons is illegal. Please obey the laws of the land and be a good law-abiding citizen.

Can humans can can control the sex of a fetus?

Of course, if you want to control the gender of the fetus, you can easily do so by using the three-generation IVF technique. Three-generation IVF, also known as pre-implantation genetic diagnosis, is a technique that helps humans obtain healthy newborns. Certain couples are born carrying certain specific gene segments, and if these segments are chained to the XY chromosome, gender-specific offspring development can occur. For example, a genetic disease located on the Y chromosome is fixed to develop only in boys, and this can be avoided in the couple's next generation by using the three-generation chromosome technology to allow the couple to have only girls. This is called medically mediated sex selection. It is really a desperate measure. If large-scale fetal sex selection occurs for some absurd purpose (e.g., to carry on the family line), it will cause serious social problems. That's why the state does not allow Chinese citizens to engage in sex selection for non-medical reasons, and please understand the state too, okay? Your country is already having a hard time, and it's hard for her too!

What the heck is Alkaline Pregnancy? Does it control the sex of the fetus?

There have been a series of rumors circulating about "acid-alkaline balance": alkaline body is less likely to get cancer, to get rid of sub-health, you need to eat alkaline food, alkaline body women are more likely to give birth to boys and so on.

These rumors are pure nonsense. First of all, the pH level in the human body is constant, once the body ingests a lot of alkaline food absorbed into the blood, the body will secrete a lot of buffer substances to balance the pH level, in order to make the body's pH level balance in a constant range, which is the so-called "homeostasis". This is the so-called "homeostasis", which is more stable than the old man's (the stalk of "old man's homeostasis"). You can't break this balance and make the body fluids alkaline unless you have alkalosis, thank you very much. By the way, alkalosis is very dangerous, more likely to die than acidosis. In this case, the first rumor is not really a "rumor", after all, people shi early indeed less likely to get cancer.

The reason why fraudulent supplements like Alkaline Gestation have become so popular is that they take advantage of the rumors above. The fact is that both the alkaline body itself and the fact that alkaline women are more likely to have boys are nonsense. There is not a single piece of evidence that proves that external factors (temperature, humidity, pH, etc.) can change the sex of the fetus. Humans have the disadvantage of having long reproductive cycles and fewer offspring. Any of the physical or chemical factors that can alter the human sex birth rate could easily make humans extinct. The fact that humans can be at the top of the food chain is enough to be able to demonstrate the randomness of human births of different genders.

Also another PS: only in reptiles and amphibians is the sex of the offspring affected by temperature and pH. Not only is Alkaline Gestation scamming people, but it's indirectly calling all of you animals, too!

Thanks for the invite.

About the birth of a boy or girl stories and practices are strange and mysterious. And in our real life, God's magic tricks, ask God's fortune-telling, couples to participate in a variety of cohabitation, get along with, pregnancy period time, diet and living configuration, seek medical advice and secret prescriptions, catching ghosts and God's tricks, the birth year and month of each other, ejaculation number and the good period of time, the formula for the birth of a male means of calculation and so on. However, no couple has ever succeeded in relying on man-made recipes. Or rely on scientific genetic single and double coefficients collision combination and produce men and women.

Simple and elegant, without any formula. If it is held by people, by private positions, by perceptions, by family blackmail. The world would be in chaos, the sex ratio would be skewed one way or the other, and the human race would naturally be destroyed and exterminated by extreme warfare.

There is no truth in the acid-alkaline theory, but the birth of boys and girls has been able to be artificially controlled.

The first method is artificial insemination (AI), which allows for the separation of male and female sperm based on a slight difference in the motility of the X and Y chromosomes, and then injecting the sperm into the uterus as desired. However, this method of differentiation based on sperm motility does not guarantee 100% purity, with a success rate of 70-72% for a boy and 69-75% for a girl.

The second is In Vitro Fertilization (IVF), in which multiple eggs are stimulated by medication, removed and fertilized in vitro, and when the fertilized egg grows to 6-8 cells in size, one cell is removed from it for gender diagnosis, i.e., Preimplantation Genetic Diagnosis (PGD). If the sex matches the desired one, the fertilized egg is implanted into the uterus. This method has an accuracy rate of between 97-99%, but it is not always successful as none of the fertilized eggs are likely to be of the desired gender.

Fetal sex selection is illegal in many countries, it is legal in the US for the purpose of avoiding genetic disorders, so it is legal, and Southeast Asia has carried out this business in attracting Chinese.

IVF/PGD is expensive, $20,000 for one in the US. Removing the eggs is a painful process and the medication taken has side effects. If it's not the gender you want, you can choose to freeze the fertilized eggs for future use, which is much less expensive next time since PGD has already been done.

IVF/PGD success rates depend on the age of the pregnant woman, with success rates above 35 years of age at 46%.

There are a lot of tips on how to have a boy or a girl when you go online, and one of them is the acid-alkaline constitution that determines gender.

Does it make sense?

Alkaline environments are said to be more favorable for the survival of Y-chromosome-containing sperm.So there are people who come up with all kinds of ways to change their physique, such as eating less meat and more vegetables to make themselves alkaline, in order to give birth to a boy; there are even people who use an alkaline or acidic solution to flush the vagina before intercourse to change the acidity and alkalinity.

This method is obviously not desirable, the human body's PH value is relatively stable, not because of dietary changes and big changes, and single nutrition will cause a lack of certain nutrients, but not conducive to conception is also not conducive to the health of the mother and fetus. If you want to change the pH level of the vagina through vaginal douching, it will inevitably cause disruption of the vaginal environment, triggering an imbalance of vaginal flora.

Other tips for having a boy or girl are:

The birth of a boy or a girl in the Qing dynasty chart;

Duration of coitus; position of intercourse; frequency of sexual intercourse, etc.

None of the above methods have an exact scientific basis.

The only way to artificially control men and women is to have a fertility doctor, but doing so toLegal sex selection to avoid hereditary diseases in offspring.

Thanks for the invitation! There should be no relationship between having a boy and a girl and their physique. From a scientific point of view, the birth of a boy or a girl cannot be artificially controlled. From a genetic point of view, the sex of a child is determined by the sex chromosomes, and the birth of a boy or a girl is determined by the law of natural selection. Therefore, despite the fact that those who want a boy and those who want a girl try all sorts of ways, the birth is really not determined by man. The probability that a sperm with an X chromosome will combine with an egg to give birth to a daughter and a sperm with a Y chromosome will combine with an egg to give birth to a son is determined by the winning sperm, and is indeed beyond human control. If it could be controlled by human beings, then the gender balance in society would be even more unbalanced.
