In a society that advocates for gender equality, it is considered the same between boys and girls. However, many people still tend to favor sons over daughters, with traditional views valuing boys over girls. Yet, today, there are also many young parents who prefer having girls rather than boys.

In the ten months of pregnancy, whether a baby is a boy or a girl is determined by what factors? What kind of food can be consumed to favor either boy or girl? Today, let's talk about the subject of having a boy or a girl.

We all know the basics of having a boy or girl, but it's not something we can control through human intervention. However, there are many folk remedies that have been passed down for generations, hoping to predict the sex of the baby. Today, I've compiled this information to hopefully help everyone out.

1. For a female body environment that is acidic, it is recommended to avoid consuming too much alkaline foods and instead consume an adequate amount of acidic foods. However, one should not consume too many acidic foods as this could potentially affect their health. Both the male and female partners should ensure balanced diet intake.

It should be noted that the acidic foods mentioned here are not taste or texture sour foods, but rather refer to imbalances in the human body's acid-base balance.

2. The older the couple gets, the greater the likelihood of having a girl. This is an undeniable fact: when parents are older, there's a higher chance of having a daughter.

The age factor can affect the physical condition of both men and women. As men age, their sperm count decreases, while older women experience a gradual decline in the alkaline secretion in their uterus, significantly increasing the chances of giving birth to a girl.

3. Women who consume vegetarian and sweet foods are more likely to have girls.

Scientists in the UK have discovered that vegetarian pregnant women are more likely to give birth to daughters.

There is no other research to date that has explored the impact of maternal diet on child sex. But a study in Britain found that there are 106 boys for every 100 girls, but 85 boys for every 100 girls among vegetarians.

This data indicates that vegan pregnant women are more likely to have daughters.

At the same time, researchers in America found that food could influence the ovarian tubes of a woman's reproductive system and make the "survival ability" of a certain sex embryo stronger.

Therefore, the content of sugar and fat in a woman's diet has a certain impact on the gender of the fetus.

Women who enjoy sweets are more likely to conceive a girl.

4. Parents who smoke tend to have daughters, and the chances of having a boy are about 50% lower if both parents smoke while in the process of conception.

Parental smoking may "kill" male fetuses in utero.

The immediate cause of a father's smoking, the passive smokers in the environment around him, are more likely to have girls.

It was suspected that smoking might cause some changes in the mother's body, such as decrease of estrogen secretion or uterine lesion. And male sperm has a decisive role on the sex of the child and sensitive to the change, so it may be damaged and have a lower chance to give birth to boy.

5. Parents with attractive features have a higher likelihood of giving birth to girls as the first child, according to an interesting study based on statistics that found parents with attractive features had a 26% higher chance of having a girl than a boy. Whether this observation has any scientific basis remains to be seen, but it does reflect the different "evolutionary strategies" of men and women.

Therefore, if you want a girl, look for a pretty partner! The choice of a boy or girl is somewhat in the hands of whoever it is. In some traditional families, having a son is seen as the woman's greatest responsibility, and when families are unlucky in not having a son, they often blame the woman.

So, who decides whether it's a boy or a girl? Is it the man's mistake, or the woman's fault? Today we'll take a look at this together.

The female sex chromosome is XX, and a woman can only produce one egg per month.

The male's sex chromosome is XY, which can produce two types of sperm: one containing X and the other containing Y.

When sperm and egg combine, they fuse together to form a fertilized egg.

So the 23 chromosomes from the sperm and the 23 chromosomes from the egg combine to form a pair of chromosomes.

If the sperm X and egg combine, the pair of chromosomes in the fertilized egg will be XX. The fetus will develop into a female.

If Y sperm and egg combine, the pair of chromosomes in the zygote will be XY, and the fetus will develop into a male.

From this, it can be inferred that the gender of the child depends on whether the sperm of the male carries X or Y chromosomes, and is unrelated to the egg.

At fertilization, the combination of male sperm and female egg is random, with equal opportunity for both XX and XY combinations.

Theoretically speaking, the chances of a baby being born boy or girl are actually equal.

Whether a child is born male or female primarily depends on the chromosomes of the man's sperm. Therefore, from this perspective, it is determined by the man.

However, research has also suggested that there may be a certain correlation between the gender of an infant and their mother's dietary habits before pregnancy.

Regarding the gender of a child, who is primarily responsible? Some beliefs also suggest that the sex of the child is related to the female ovulation period and vaginal pH environment.

Because the newly released egg has strong vitality, if the pH value of the female vagina is weakly alkaline at this time, the egg is more likely to combine with Y sperm and give birth to a boy; On the contrary, when it is acidic, it is easier to bind with X sperm and has a higher chance of giving birth to a girl.

It seems that boys and girls are largely influenced by their mothers.

In fact, every pregnancy is extremely complex, and it is a natural process. The choice of having a son or a daughter is not what we advocate for. As long as the baby can be healthy, that is the greatest happiness for the expecting parents.

It is well known that there are differences between boys and girls when it comes to pregnancy. The symptoms of carrying a baby boy or girl differ.

So, what are the differences between boys and girls? Let's take a look at how the babies in pregnant women react to their different genders.

Difference 1: Judging symptoms by the pregnant woman's belly shape.

The pregnant belly is pointed and bulging, suggesting that the baby will be a boy.

If a woman's belly is round, she's likely to have a girl.

Difference 2: Observing changes in the appearance and skin of pregnant women

It is believed that if a pregnant woman's appearance becomes more attractive and her skin becomes smooth, it may indicate the possibility of having a girl.

Conversely, if one's appearance changes, their skin becomes rough, or acne develops on their face, these symptoms may indicate the presence of a male fetus. This is a common observation regarding the signs of whether a baby will be a boy or girl.

Difference 3: Changes in taste preferences for pregnant women.

Some people believe that if a pregnant woman's taste changes from what she had with her previous child, then the gender of her baby will change.

Difference 4: The speed and strength of the fetal heartbeat.

It is generally believed that a fetus with a stronger and slower fetal heart rate has a greater likelihood of being male.

Conversely, this is the common guess that a girl will be born if there are symptoms or methods to predict whether it's a boy or a girl.

Difference 5: Women who are expecting a boy tend to overeat their usual favorite foods.

The average amount of protein, carbohydrate and fat consumed by pregnant women who are carrying a male fetus is 8%,9% and 15% higher than those who are carrying a female fetus respectively.

Pregnant women who are pregnant with male babies eat more food than they did before, but not different or strange foods, but eat the food they like.

6. Observe the appetite.

The male hormone testosterone secreted by the male fetus signals its mother that it needs to eat, prompting a significant increase in her food intake.

Moreover, although mothers carrying male babies are heavier at childbirth, the increased weight during pregnancy is not greater than that of mothers carrying female babies. Thus, it can be inferred that the gender of the baby does not affect a woman's weight.

The concept of choosing a boy or girl through food is not something that can be controlled by us. There are many folk sayings about it, but in reality, the gender of a child cannot be determined by diet.

So, what are the dietary methods for having boys or girls? Today, let me share with you.

Gizzard of male fish: Especially the tail, which contains a higher level of androgen hormones, can stimulate and adjust the female gonads axis. However, it is also possible that this can increase the number of ovulations in women. If a woman becomes pregnant while taking gizzard, the fetus may easily have multiple births or twins.

Savory food: Scientists believe that eating red meat and salty fast food will give a boy, while chocolate will help to give a girl.

Diet can affect the environment of the uterus and make it more suitable for carrying sperm with an X chromosome or a Y chromosome.

Alkaline-forming foods: For expectant mothers aiming to conceive a boy, it is suggested to consume more alkaline foods. This type of food can balance the body's acidity and make it more alkaline, thereby increasing the chance for Y sperm to successfully fertilize and bond with the egg.

Generally speaking, alkaline foods include fresh vegetables, milk, oranges, bananas, and kelp.

Diet for having a daughter: Couples who want to have a baby girl can try increasing the acidity in the female's blood, which can also increase the acidity in the vagina and be beneficial for having a baby girl.

Therefore, the woman can eat more fish, meat, protein, and acidic fruits to make her body slightly acidic.

However, for you, it is advisable to consume more alkaline-forming foods.

Acidic Foods: Eel, ham, beef, pork, chicken, fish (sea bream, tuna, porgy, salmon, saanich, mackerel, bonito, codfish, etc.), wood ear, egg white, acid fruits (tomato, orange, strawberry, grape, apple, pineapple, etc.)

There are different constitutions for boys and girls. The constitution of a boy or girl can vary depending on their genetic makeup. So, the question arises: what are the differences in physical constitution between boys and girls? Let's delve into this together.

1. Male Factors: In humans, spermatozoa consist of two types, X and Y, each with distinct characteristics.

X sperms determine the gender of the offspring, they are big and bulky, slow in movement but have long endurance, acid-resistant and have a long lifespan.

Y sperms are responsible for male birth, and their characteristics are small head, long tail, fast swimming speed. Their lifespan is short, but they can adapt to the environment. Especially in acidic environments, they are easy to die.

In the journey to reproductive cells, Y sperm often takes the lead and hence male babies outnumber female babies.

But for various reasons, the ratio of sperm to egg remains constant at 103-106:100.

2. Female Factors: With the cyclic changes of the ovulatory cycle, there are also regular fluctuations in the acidity of the vagina and the cervix of the uterus.

The safe period is acidic, and there's a mucous-like, viscous substance in the cervical region.

The ovulatory phase exhibits a slightly alkaline pH, and the mucous membrane of the cervical canal is thin and clear, greatly facilitating the passage of sperm.

However, some women still exhibit an acidic condition during ovulation, and the nipple-like mass in the uterine cervix cannot be alleviated.

At this time, if the male sperm can make use of its special endurance and acid resistance to pass through the vagina into the fallopian tubes, while the male sperm is already weakened by the acid environment and passing through the thick mucus, most of it will die in mid-process, leaving only a few remaining. Therefore, women with an acidic constitution have a higher probability of giving birth to a girl.

However, experts point out that the popularity of the acid-base theory is related to certain research suggesting that Y sperms, which determine male birth, are more active in a slightly alkaline environment. But the so-called "alkalinity" lacks quantifiable indicators and has no solid scientific basis.

From a medical perspective, the pH value of the human body is relatively constant, and it is impossible to significantly deviate from this value simply by consuming certain types of food.

Additionally, the acid-base nature of food is a field of study in food chemistry and is not the same as the acid-base state of body fluids after metabolism.
