Becoming a happy expectant father or mother, one is always curious about whether the baby inside will be a boy or a girl. The topic of having a son or a daughter is quite sensitive among people.

But it is not a random question, it is the combination of sperm and egg cells, and the final phenotype is gene.

The ratio of boys to girls in the population is 1:1, but it doesn't apply to everyone. For some families, the ratio is 1.15:1, meaning that some families have more sons than daughters. This is known as genetic factors.

Having a boy or girl is mysterious, but it's not determined by fate; rather, it is decided by the two parties.

The ratio of male to female births is generally 1:1, unaffected by human choice.

Why do some people want boys and yet have girls? Why do some people need to have girls but end up with boys instead? What is the reason for having a boy or a girl at all? From ancient times, there have been countless speculations about this, but none of them are based on scientific evidence.

Every pregnant woman and her family wants to know the gender of their baby early on. So, is there a certain pattern? Consequently, modern people have created a fetal sex calculator. According to many users' feedback, this sex calculator has a high accuracy rate of up to 90%. Therefore, expectant mothers who wish to find out the sex of their baby should not miss this opportunity. However, it's important to remember that the gender of a baby doesn't matter. The fetal sex calculator, the fetal sex calculator, has been met with much astonishment and skepticism. Some are afraid it might be wrong, yet they are eager to use it to see if they are having a boy or a girl.

Although families are relatively less superstitious and more secular than in the feudal era, there is still a deep-rooted belief among many older people that it is important to have a son, and they might be inclined to use a "fertility calculator" like the one used for calculating the sex of a baby to determine whether they will have a boy or girl.

The gender prediction table is a popular tool for many expectant parents who want to predict whether they will have a boy or a girl. What are the mysteries behind this? Human cells reproduce through meiosis, which means dividing a single cell into two halves and then dividing those halves into four. This continues until only one cell remains.

During the process of developing from unfertilized gametes to fully matured ones, chromosomes in a cell must undergo one meiosis. That is, after maturation, a sperm or an egg cell contains only half of its original number of chromosomes. Of these, 22 are ordinary chromosomes and one is a sex chromosome.

The male's pair of sex chromosomes is XY, so after division and maturation, one sperm contains X chromosomes, known as X sperm, while the other contains Y chromosomes, known as Y sperm.

The female has a pair of sex chromosomes, XX. Therefore, the mature eggs after division contain one X-chromosome.

From this, it can be inferred that there are two types of sperm in males and only one type of egg in females. Therefore, the gender of a child depends on the variety of sperm cells from the male.

In such situations, the sex determination table comes into play, serving to ascertain whether it will be a boy or a girl. Its existence is not without reason.

The "Sex Determination Calculation Table" is a folk belief that the formula for determining whether a baby will be a boy or a girl is: "7749, when pregnant, how long ago?" Subtract the mother's age from this number, then add 19. If the result is odd, it's a boy; if it's even, it's a girl.

49 (base) + the months pregnant + the age in years of children - 1 + 19 = X (if it's a double number) = princess, X (if it's a single number) = prince. Mothers can also try this out, here is a table of predicting male or female children that are preserved by Qing Palace. The age of women is calculated based on their real age plus 1 year, and the month of pregnancy is also calculated in lunar calendar.

How to read the sex calculator? Let's follow our editor to understand it.

How to read the sex determination table, scientists said that every cell in human body (including reproductive cells) contain 23 pairs of chromosomes carrying genetic material, 22 pairs are normal chromosomes, and they decide all the genetic information except sex, one pair is sex chromosomes, they decide the sex of the baby.

The chromosomes are the same in males and females, with no differences in gender.

In theory, there should be a 1:1 ratio of males to females. However, if both families have siblings, the next generation will be predominantly female with one male and two daughters.

Whether it is boys or girls, or whether it is related to the habit and certain chances.

If a man drinks beer or other carbonated beverages, he will have a higher chance of having a boy. Men should be particularly careful during the fertile period to avoid drinking carbonated beverages such as Coca-Cola, as these can deactivate the Y chromosome in male sperm, thereby reducing the chances of having a boy.

These factors do have an impact on the sex of a child, so it's not advisable to rely solely on the sex calculator to determine the gender of your offspring.

The calculators for determining the gender of a baby are based on the lunar or Chinese calendar, not the Gregorian calendar. The topic of whether to have a boy or girl is one that family and friends discuss most during a woman's pregnancy. There are various methods for predicting the gender of the child.

Today, I'm going to share a rather obscure method: the birth sex calculator, which takes into account both the solar and lunar calendars. Let's take a look at how it calculates whether a baby will be born male or female based on the solar and lunar calendars.

The method of determining whether a baby will be born male or female based on the lunar and solar calendars is often combined with the parents' birth dates and the pregnant woman's date of conception.

What are the specific methods? Let's take a look at the editor's share.

Method 1: Based on the pregnant woman's date of pregnancy and the age of pregnancy, add 49 to the pregnant woman's date of pregnancy (in lunar months) + the age in years at the time of conception (age in full years) + 19. The resulting number is then subtracted starting from 1 until it cannot be divided any further.

The last visible odd or even number represents a boy if it is odd, and a girl if it is even.

If it's the 7th month of the lunar calendar when you conceive, your actual age at the time of conception is 22.

49+7-22+19=8, and then it is subtracted again, finally getting 8, which is even. This represents a girl.

Calculation Method 2: According to the father's birthdate and the mother's pregnancy date, add the father's birthdate (year + month + day) + the mother's birth date (year + month + day) + the mother's pregnancy date (lunar month) - 19. If the final result ends with an odd number, it signifies a boy; if it ends with an even number, it signifies a girl.

For example, if a child is born on September 15th, 1989, and the mother is born on October 9th, 1989, then the sex of the child born in July would be determined by calculating the sum of the dates: (89 + 9 + 15) + (89 + 10 + 9) + 7. The result is 209, and since the last digit is odd, this indicates that the child will be a boy.

Calculation method 3: Provide the pregnant date and age of the expectant mother, using only the woman's age at the time of pregnancy (virtual year)+the date of pregnancy (lunar month), and see the final digit.

If it is an even number, it is mostly a girl; If it is an odd number, how many are boys.

For example, in the eighth lunar month of pregnancy, the virtual age at the time of pregnancy is 26, which means 26+8=34. If the number ends in an even number, it indicates that it is a girl.

Is the calculation table for male and female births accurate? Are male and female watches accurate? How do we count having a boy or a girl? Many expectant parents are very interested in this.

Both boys and girls are the same, the same

People around ask, it's really just about getting ready. The boy gets his stuff, and the girl gets hers.

Regarding these rumors about the gender of a child, which ones are true? So, does the "Birth Chart" really work? The folk proverb goes: "Seven seventy-nine, ask when your pregnancy began; remove the mother's year and day, then add one nineteen, for even numbers it's a boy, odd numbers it's a girl."

49 (constant base) + the lunar months when pregnant - the age in years of a child in the womb + 19 = X.

If X is a double (i.e., a princess), then

X (if it's a single) is the Little Prince.

Dietary control can determine the gender of a child.

In the natural process of conception, the likelihood of having a boy or girl is equal, at 50%.

The following methods are compiled by Japanese professors and collected relevant materials. Although these methods have not been rigorously validated through scientific methods, they are not as unfounded as the folk remedies that are popular among the general public. They are simple and clear in their execution. Parents looking to conceive may find them useful.

Dietary control method: This refers to the idea that altering the body's acid-base balance by eating certain types of food can influence the sex of a child.

Female vaginas are generally acidic, and if a female ejaculates an alkaline substance during orgasm, it is more conducive to the survival of Y sperm. Those who want to have a boy may need to take note of this; those who want to have a girl should maintain an acidic environment in their bodies.

Dietary control is a method of dividing food into acid, alkaline and neutral. For men, it is beneficial to eat more acidic foods; for women, it is helpful to consume more alkaline foods. This can help in the birth of boys. For men, it is good to eat more alkaline foods; for women, it is advantageous to consume more acidic foods.

However, the claim that dietary changes can affect a person's genetic makeup and thus determine their gender is not yet proven, and it may be necessary to rely on chance.

In fact, as long as you don't have a food allergy or intolerance, and you consume an adequate variety of foods, this approach is also quite acceptable.
