Why do some people have children who keep having girls?

(Doctor and patient home special answer: Concordia A Wei)

In real life, this situation does exist, some families have six or seven girls in a row, so what are the reasons?

First, according to the normal ratio, the ratio of male to female births is one to one. For families that have girls consecutively, one possible reason is the probability that 50% of them happen to be girls each time, and if we look at the probability, as long as enough children are born, the ratio of male to female will gradually approach one to one. So, we see some families who are trying to have a boy child, often after having 6 or 7 girls, get a boy child, and hypothetically, how these families continue to have more boys later on instead.

Secondly, some people think that there is a relationship between having a boy or a girl and having an acidic or alkaline body, but in fact there is no absolute proof that this is the case. What really determines the birth of a boy or a girl is the father's sperm, which is divided into two kinds: X and Y, and the mother's egg is only one kind of X, and when the Y sperm combines with the X egg, it is a boy.

So having girls all the time doesn't mean that these families don't have the ability to have boys, it's a matter of odds.

Why do some people have children who keep having girls?

This question has plagued the Chinese nation for 5,000 years, and how many families have been stealing, overbearing, and even divorced because of having sons!

I have a friend who once talked about family matters. She said that their family has seven sisters, the whole is seven fairies. The oldest is almost 60 and the youngest is only in her 20s. It is that they want a son, so there are constantly having children.

There is also a relative, the family is also three daughters old four is a son. In the absence of a son before, the family hid, home furniture, appliances are punished. The two adults with three children displaced, the days of the hunger of a full meal. But still, they wanted to have a son. Eventually, they finally got what they wanted.

Is a son really that important? In the eyes of our Chinese parents, the son represents the inheritance, the future hope, represents everything.

Just now I said that some people have always had daughters, but some people have sons all the time. The reason for this is that there is a lot of money to be made in the marketplace.

We all know now that the birth of a man or a woman is in the man. Sperm contains two kinds of chromosomes: the x chromosome and the y chromosome. A boy is born when the Y chromosome combines with an egg cell to give birth to a boy. However, the x-chromosome sperm prefers an acidic environment, and the y-chromosome sperm prefers an alkaline environment.

The Y-chromosome is smaller and faster than the X-chromosome, but it's weaker, so it's a bit of a hothouse flower. If a man is working hard, he'll have to stay up all night, smoke and drink, and live an irregular life, so the Y chromosome in his body will have a hard time surviving, so it's hard for him to have a boy.

The x chromosome is just stronger, acid-resistant, and more capable of life. It can survive in the uterine cavity for 2 to 3 days, and because the female vagina is acidic, the x chromosome is more likely to win. That's why more girls are born than boys.

So, control your diet, live a regular life, and count your ovulation dates so that the Y chromosome has a better chance of winning.

Finally, I think boys and girls are the same. There is no need to consider the matter of succession, down the number of three generations who still remember you? I'm afraid of burning paper without your share? The first thing you need to do is to make sure that your children are well behaved, that they are respectful of their parents, that they are respectful of each other, and that they are happy for the rest of their lives!

This situation is actually not uncommon, has confused the Chinese people for thousands of years, and there is even a saying that the more you want to give birth to a son, the more not born, a string of daughters, of course, this belongs to nonsense ah.

I remember I have a friend, their family has six daughters, she ranked herself the oldest, she said her mother because she did not have a son often suffered from her grandmother's cynicism, the grandmother said that did not give birth to a son, the daughter-in-law to continue to give birth to a daughter-in-law is not the right to give birth to a son ... .... His mother could not stand the pressure, had to continue to work hard, at the age of 40, finally gave birth to a son, which the succession of things only end.

But because the whole family on this son too much importance, what to give what, incomparable arrogance, from a young age also did not control, to the age of 16 years old, eating, drinking, stealing and playing all kinds of things will be, a young age into the correctional center.

After hearing this story, the heart is still quite sad.

After hearing this story, I was quite sad. What era is it, still so patriarchal, is to give birth to a male child out of it is not good discipline.

Some people will feel that the birth of a daughter mainly lies in the female side, in fact, it is wrong, the main responsibility is in the male side.

There are 23 pairs of chromosomes in human cells (46), one of which is a pair of sex chromosomes, 22 pairs of autosomes, and the sex chromosomes are the determinants of gender.

The female sex chromosomes are XX and the male sex chromosomes are XY, which means that male sperm contains both x and Y chromosomes. To have a boy it is the combination of the Y chromosome and the egg cell that gives birth to a boy.

There is a saying that if a man is stressed out every day, stays up late, smokes and drinks, and lives an irregular life, the sperm containing the Y chromosome in his body will have a hard time surviving, so it's more difficult to give birth to a boy.

So if you want to have a child, it's best to do a good eugenics check, relax your mind and go with the flow. As for eating want to have a boy, women eat more alkaline food, men eat acidic food is no scientific basis, do not recommend blindly follow.

In fact, now that the birth of a two, the birth of a boy and a girl are not the same? We have a generation of people, old time do not expect the children back to take care of us? They are also busy in the middle age, they are very busy, life is very stressful, I feel that there is not much to count on ah, save a little money, live in the nursing home is also more real.

In the past, I've read a book on how to get married, and I've seen that when you're married to a woman who likes to eat vegetarian and acidic food, you have a better chance of having a boy, and if you like to eat meat, you have a better chance of having a girl, and I've seen it through a lot of years of observation, and it's not quite accurate.

My neighborhood corridor a side are born girls, there are more than a dozen little girls playing together, there is a family of two sons and a girl, I hope to hold grandchildren, three sons and daughters gave birth to four granddaughters, two granddaughters, to do the grandpa's is laughing and crying, the people have to ask if you want a boy or a girl, the people are talking about the same boys and girls, but the heart is still want to have a boy.

I after years of observation in this regard, today's society and economic development is relatively fast, the employment mechanism is to choose the best talent, eliminating the inferior talent, resulting in the male comrades work under pressure, mental pressure is not small, the physical strain is more exhausting, and at all times have to make good efforts, a little carelessness will be dismissed may be in the conjugal sex life of some men are at a disadvantage, the woman is in strong, this situation will be the best way to make the best use of your time. In the strong, this situation will have an impact on the birth of children, women's sex life in the strong when the birth of the girl will be the majority of women with strong sexual function will be outside to find a man, the husband can not meet her.

The so-called strong sexual function of the woman, there is a strong desire for sexual function, each time the sex life is her initiative to come forward, and the request for sex is also more frequent, leaving the man as if he could not live with the woman, if the husband is working outside the home for a long time not to come back home, the likelihood of this woman derailed than the big one.

Women in the sexual function of the strong and weak, there is a considerable portion of women's sexual function in the weak:, in the strong woman is often not satisfied with her husband's sexual desire, strong women in the sexual life will be in the initiative, sexual function of the weak women in the sexual life will be in the passive, if her husband is small and not sturdy, the strong woman will be outside to look for a third party, the sexual life is in the strong! Women's children are mostly girls, sexually vulnerable women's children are mostly boys, this is my observation from real life, and not too scientific only for everyone to test.

The country is now more men than women, are in the country a child policy, we all want to have a boy, when pregnant, found that the girl was aborted, and now the two-child policy is good, where it is a couple of two children, do not ask to give birth to a boy or a girl are the same, the imbalance between men and women will be gradually narrowed.

I have a relative she is rural, gave birth to three daughters, according to the birth control policy at the time, can not regenerate. The first time I saw this was when I was a student at the University of California, Berkeley, and the second time I was a student at the University of California, Berkeley, and the third time I was a student there. She was forced to give her 4 daughters, who were born less than 3 days ago, to a family with no children.

Then the family became more anxious and looked for a prescription for a son. My relative is pregnant again with her fourth child. The first time I saw her, I had to take an ultrasound, and I was told that she was still pregnant with a girl, and the family tried to find a way to get her to take the pills. Unfortunately, the baby was still a daughter. Her parents-in-law scolded her, saying that she had ruined their family. Later, there is no way, from the field to adopt a boy, and now this boy have become a family, but not at all filial piety to my relatives, my relatives because of the birth of too many, coupled with the menstruation did not sit well, less than 60 years old, there are a lot of problems, last year the Spring Festival to go to her home, the body is so weak that can not get out of bed to walk.

We look at the mystery of the birth of a boy or girl

There are 23 pairs of chromosomes in human cells (human genetic material), of which there is only one pair of sex chromosomes, the sex of the fetus is determined by it. These two sex chromosomes, one from the mother, one from the father. If both chromosomes are X-type, a girl is born; if there is one X-type and one Y-type, a boy is born. A woman's ovaries usually produce only one mature egg cell per month and contain only X-type sex chromosomes, which means that the sex of the fetus is not determined by the mother.

The male testes constantly produce sperm, which are of two types, one containing the X chromosome and the other the Y chromosome, in equal numbers. The combination of an egg cell with a different type of sperm determines the sex of the fetus. However, which type of sperm will combine with the egg is completely random, not governed by the will of the people, and not related to the function of the organ.

Scientifically speaking, there is no "responsibility" for the birth of a boy or a girl on the part of either parent.

From a biological point of view, it has something to do with the male chromosome, from the male and female chromosome combination probability, there are only two possibilities: XX and XY. If some women have always been born a girl, that is to say, the chromosome combination is always the XX combination, each time only accounted for fifty percent of the possibility of this kind of probability, if placed in a single pair of couples, the probability of occurrence of the possibility of completely there, and the possibility of the occurrence of the XX and XY. This probability is entirely possible and understandable if it were to happen to a single couple.

Plus the Y chromosome degradation theory, there is no evidence to show what causes its degradation, but some scientists have found traces of the sex ratio of newborns in some countries, such as Japan's Hyogo Prefectural M&K Health Research Institute founder Misao Fukuda (Misao Fukuda), in a recent study, the newborns in Japan, gender imbalance seems to be related to fluctuations in external temperature. appears to be linked to fluctuations in outside temperatures.

Then there's Samuli Helle, a senior researcher in ecology at the Department of Biology at the University of Turku in Finland, who has also found a pattern of higher temperatures making it easier to have boys. By studying the Sami people of northern Finland, he quantified the pattern: for every 1-degree Celsius rise in temperature, the proportion of newborn boys increases by 0.06 percent; if the temperature rises by 3 degrees Celsius per year, the proportion increases by 0.18 percent. At first glance, this effect is not significant. However, because of the large population base, thousands more boys would be born each year.

But the two experiments mentioned above do not give an experimental conclusion for individual families to have girls all the time, but only an experimental data from the overall ratio of boys to girls. Therefore, it can only be explained by probability theory.

The modern society is more and more developed, the transportation is more and more convenient, people prefer men to women's thinking is also reduced a lot, but we have to deny that in many families still retain the traditional "raise a child to prevent old age" thinking, I have a classmate, the first child gave birth to a daughter, wanting to son, the second child gave birth to a daughter, continue to give birth to a three-child, I did not expect the third child gave birth to a twin, but I did not expect the third child gave birth to a twin, and I did not expect to see the third child gave birth to a twin. Unexpectedly, the third child gave birth to twins, two daughters. Considering that the cost of raising a child is too high, he gave up the idea of having a son, and let nature take its course.

Why do some people keep having girls?

Many people say that it is the male's genes that determine the birth of a boy or a girl, but in fact this is not entirely true. Although scientifically speaking, the male's chromosomes determine the sex of the child, the fact is that the mother's body receives which sperm from the male is also a very important aspect. Although the mother does not directly manipulate the sperm, she can influence the environment in which the sperm and the fertilized egg live.

The health of the mother determines whether or not a girl is born.

Mothers are more likely to have girls:

1. Long-term exposure to toxins that are harmful to reproductive health, such as pesticides, fungicides, fumigants, lead, and other toxic substances.

2. Long-term smokers and alcoholics are more likely to have girls because the toxins in her body change hormone levels, lowering the level of testosterone and increasing the level of progesterone, indirectly favoring the sperm carrying the x chromosome.

3. Cancer survivors who have undergone chemotherapy are more likely to have daughters.

Men with more girls in the family are more likely to have daughters

Scientist Cory Gellatly of the University of Newcastle upon Tyne in the United Kingdom put forward the hypothesis of sex selection operation said that he analyzed 927 genealogies, Gellatly case came to a surprising statistical conclusion: men with more brothers are more likely to have sons, and men with more sisters are more likely.

The pattern of having daughters is present in men, but not in women.

Gellatly explains this phenomenon in terms of total evolution, it is about the survival of the species, when there are too many men in the population, men with boy-prone sperm are less likely to pass on their genes to their offspring than men with girl-prone sperm, because in this case men have fewer chances to mate than women, and when there are too many women in the group is the situation poorly precisely l, on the contrary, in order to maintain gender balance sex ratio example will go up and down like a see-saw.

A woman's pre-pregnancy weight can also be used as a reference for having daughters

Italian researchers collected data on nearly 10,000 new mothers, and they found that the 25% of women who weighed the least were significantly more likely to have daughters than those who weighed more, regardless of their height. If a woman is very thin, she might consider this caloric restriction a sign of existential stress and nutritional deficiencies.

I don't know anything about chromosomes, but I believe it's mostly to do with men, and most of it is due to the fact that men have too many nights out, I guess. If a man really wants to have a boy, he should first control his "animal desire" and do it in a controlled and regular manner in order to achieve the ultimate goal. Of course, this is not absolute. (In my humble opinion, it is normal to have different views, don't be offended! I'm not sure if you're going to be able to do that.)

Humans are mammals, and their sex determination depends on the Y chromosome, which is strongly androgenic. The original understanding of the mechanism of sex determination in humans came in the 1940s, when scientists doing research using rabbits discovered that the gonads are important organs in mammals for determining the necessity of males. Subsequent studies have continued to show that sex determination in species falls into two main categories: environmental sex determination and genetic sex determination.

Environmental sex determination

It has been found that in some animals and plants, sex is determined by environmental factors, including temperature, PH, social factors, and seasonality. The temperature factor is the most typical. For example, red-eared turtles tend to produce females at higher temperatures, and American alligators produce females at lower temperatures. Although these studies have not been conducted in humans for ethical reasons, humans, as advanced animals, are also affected by these factors, and it should be assumed that the production of males and females is also affected by the temperature of the environment at the time of insemination or the season. Similarly, diet, living environment, etc. may affect the birth of a boy or a girl.

Genetic Determination of Sex

Genetic determination of sex indicates that males and females of a species have different genetic information, i.e., the sex chromosomes determine the direction of gonadal development. Most mammalian males carry XY chromosomes, while females have XX chromosomes. In recent years, it has been found that the Y chromosome carries the Sry gene, which encodes a transcription factor that initiates the development of the gonads into testes, while in females there is no Y chromosome, no Sry gene, and thus the gonads develop into ovaries. So when the Sry gene is down-regulated or absent, the gene that activates the development of the gonads into ovaries is relatively active, and thus girls are more likely to be born.

In fact, the birth of a boy or a girl belongs to the laws of nature, we do not have to intervene too much. Nowadays, with gender equality and the blurring of the social division of labor between men and women, the gender gap is no longer so important.

Why do some people give birth to girls?

It's not just a matter of time, it's also a matter of time.

Many people think that having a boy or a girl has to do with diet and the body, and that's one aspect.

But we can find that some women can only give birth to daughters after a certain man, and can give birth to sons after a different man. There is no way to explain this with science.

Children are destiny. Some people are destined to have only daughters, some are destined to have only sons, some are destined to have children, and some are destined to have no children.

The first thing you need to do is to get your hands on a new one, and then you'll be able to get a new one.

In life, many people prefer sons to daughters, in order to have a son to eat a variety of traditional Chinese medicine, a variety of dietary therapy, and some people do not hesitate to abort their daughters again and again, just to get a son.

The son who got this way is either no good, or a loser. The first thing you need to do is to get a good job of it, and you'll be able to do that.

We have to follow our destiny, no matter what boy or girl, we have a deep destiny with ourselves, and if we educate ourselves well, we will become proud of ourselves.

As a parent, you should not worry about the gender of the child, but should think about how to educate the child to become a success.
