Some people like girls because they are obedient and clever, understanding others well, and considerate.
Some people also prefer having boys, as they can inherit the family business and carry on the lineage.
Regardless of the reason, I say that having a boy or a girl is equally good. It's all about the joy of being pregnant and giving birth to your own child, regardless of whether you are holding their hands or not, because every child is precious to you.
Moreover, from a scientific perspective, the chances of having a boy or girl are equal and each accounts for 50%. This is why the overall male to female ratio in humans is close to one to one.
However, from another perspective, the fact that boys and girls are born in greater or lesser numbers is due to whether the sperm entering the egg carries an X-chromosome or a Y-chromosome.
Because the female egg carries a chromosome that is always X, if the Y chromosome enters, it's a girl; if the X chromosome enters, it's a boy.
The decision to have a boy or a girl is not solely in the hands of either parent. In ancient times, if a woman could not conceive a boy, she was deemed at fault and her husband would continue to marry concubines to ensure the continuation of the family's lineage.
The wife of the eldest son is forced to tolerate her husband's marriage with a concubine, as she cannot give birth to a male heir for the family line. Being unable to produce a male offspring is considered an offense.
So, who decides whether a child will be born boy or girl? Let's explore this with the editor below: In fact, according to modern medical explanations, the decision on whether a child is male or female is not determined by the woman. Outside of external factors, it is mainly determined by the male partner's sex chromosomes.
Sex chromosomes are the chromosomes that determine gender.
Humans have 23 pairs of chromosomes, or 46 in total, including 22 pairs of non-reproductive (or autosome) chromosomes and one pair of sex chromosomes.
The sex chromosomes for females are XX, while males have XY.
The eggs contain only one type of chromosome, X, while the sperms have X and Y.
When a sperm containing an X chromosome is combined with a ovum, the resulting fertilized egg is XX and develops into a female fetus.
When the sperm containing an Y chromosome is combined with the egg, the resulting fertilized ovum is XY and develops into a male fetus.
Therefore, the decision to have a boy or girl is determined by which sperm containing an X chromosome or one containing a Y chromosome fertilizes the egg.
Alternatively put, the gender of a child is determined by the male partner.
However, the gender of a child is also influenced by external factors such as environmental pH levels. Y-sperm is tolerant to alkaline conditions and can easily bind with ova in an alkaline environment; X-sperm is active in acidic conditions and tends to fertilize more readily.
In addition to this, there are external factors such as age, occupation, and stress.
Is the gender of a baby determined by whom? Can this be proven scientifically? It can be found online that there are factors that determine whether a baby is male or female, some say it depends on the mother, others on the father, and others on external influences such as pH levels, season and temperature, occupational factors, age, stress, etc. So who is responsible for determining the gender? Is there any scientific basis for it? Modern medicine has confirmed that, aside from other external factors, the gender of a baby is mainly determined by the male partner's sex chromosomes.
Humans have 46 chromosomes in their reproductive cells, of which 23 pairs are the ordinary chromosomes and 1 pair is the sex chromosome. The sex chromosome in females is XX, and the genotype can be expressed as 46, XX.
The male sexual chromosome is XY, the genotype is 46,XY.
Gametes undergo two meiotic divisions, 23 pairs of chromosomes become 23 chromosomes. Ovum contains only one sex chromosome X, and sperm can contain either X or Y sex chromosome.
When sperm and egg combine, the chromosomes of the fertilized eggs are restored to 23 pairs.
If the sperm containing an X chromosome fertilizes a ovum, the resulting zygote is XX and develops into a female fetus.
If the sperm containing Y chromosome is combined with the egg, a zygote of XY type is formed and develops into a male fetus.
Therefore, the sex of the child depends on whether it is an X sperm or a Y sperm that fertilizes the egg.
The union of sperm and egg is random, and it does not depend on people's will. This is the basic balance of human gender ratio, which is also an ecological balance in nature. This balance cannot be broken. Otherwise, it will inevitably lead to unimaginable social problems.
What determines whether a child is born male or female? The debate on whether it's the mother's choice has been a topic of controversy for centuries.
Elders prefer boys, mainly because they can carry on the family line and continue the inheritance.
As time progresses, there is a growing emphasis on gender equality, with the idea that having a son or daughter is equally important.
However, people still hope to control the gender of their children. Consequently, there is a desire to understand what factors determine whether a baby will be born male or female. 1. Season of Conception Influence. Many people believe that the season of conception, which is the month before the sperm and egg meet, is a significant factor in determining the baby's gender.
To some extent, the season of conception can indeed affect the gender of a child.
However, pregnant women should not overly fixate on the season to conceive. The season of conception does not play a crucial role.
What's needed is the result of a combination of favorable timing, location, and harmony.
2. Rumors circulate that the pH level has an impact on the gender of a fetus, but this is not supported by scientific evidence.
Many couples who want to conceive a boy are trying to create a more alkaline environment by rinsing their vaginas with 2% or 2.5% sodium bicarbonate solution before sexual intercourse.
The couple who want a girl can increase the acid environment before sex by washing the vagina with a suitable concentration of vinegar or 1% sodium lactate solution.
Although it seems somewhat logical, there has yet to be medical evidence for its effectiveness, and further research is needed.
Special reminder, if vaginal irrigation is used to change the acidity and alkalinity of the vagina, it will not only fail to achieve the desired baby, but also have a counterproductive effect.
This may cause vaginal infections and pelvic inflammatory diseases in pregnant women, even damage sperm, causing congenital anomalies.
This method needs to be carefully selected.
3. Due to the influence of women's ovulation period, many expectant mothers are prone to believing in folklore and believe that there is a higher chance of having a boy on the day of ovulation.
The chances of having a girl are higher if you have sex one or two days before your period.
Let's debunk this rumor here. The gender of the fetus is determined by the sex chromosomes of the gametes, not related to the time when the mother ovulates.
Humans have 23 pairs of chromosomes, or 46 chromosomes in total. Of these, 22 are ordinary chromosomes and one is the sex chromosome.
The sex chromosomes of females are XX, while those of males are XY.
The egg contains only one chromosome, X; the sperm contains X and Y.
When a sperm with an X chromosome combines with a ovum, the resulting fertilized egg is XX and develops into a female fetus.
When a sperm containing the Y chromosome combines with an egg, the resulting zygote is XY and develops into a male fetus.
Therefore, the gender of a baby is primarily determined by which type of sperm and egg combine.
The gender of a fetus is mainly determined by the sex chromosomes. A sperm carrying the Y chromosome is more active in an alkaline environment and is likely to produce a boy, while a sperm with the X chromosome tends to be more active in an acidic environment and is likely to result in a girl.
There are some rumors floating around that control the pH levels in a couple's bodies can determine whether they have a boy or girl. Let's sum up some of these for everyone to reference.
Secret 1: Dietary Regulation During Pregnancy. Since the vagina generally has a pH acidity, if the secretion of alkaline substances occurs during sexual orgasm, it is more conducive to Y sperm survival and thus easier to conceive a boy; for a girl, maintain an acidic environment in the body.
Therefore, during the preconception period, couples can change their body's pH balance by controlling their diet.
Acidic foods include meat, egg, fish, animal fat and vegetable oil, rice, noodles, sweets etc.
Alkaline foods include vegetables, tea, fruits (except high-sugar ones), soy products, and milk.
Explanation: However, from a medical perspective, the pH value of the human body is relatively constant, and it's not possible to make significant deviations by consuming certain types of food.
Preparing for pregnancy requires special attention to nutritional balance, avoiding a single diet that may lead to malnutrition.
Secret #2: Change the pH of the vagina. If you want a girl, use a little diluted vinegar (with clean water) to dilute in the three days before ovulation and then flush it out into the vagina.
If you want to have a boy, you can use baking soda water to wash the vagina three days before ovulation.
Special reminder: This method has not been medically proven, and it is easy to cause imbalance in the vaginal flora and induce inflammation. Therefore, it should be taken with great caution.
The secret to having an orgasm is to make sure you are in a safe environment and that the other person is comfortable with it. It's important to be patient and take your time, as well as to listen to your body and adjust accordingly. Remember, everyone's experience is different, so what works for one person may not work for another.
Sperm is alkaline, and at the time of orgasm in women, it increases the pH of vaginal fluid. Therefore, those who wish to have a boy should strive for orgasms that increase the likelihood of increased vaginal acidity.
Secret 4: The timing of intercourse should match the environmental temperature one month before fertilization, as it is a significant factor in determining the gender of the baby.
In hot environments, it is easier to conceive a boy, and in cold environments, it is easier to conceive a girl.
High temperatures can affect the X chromosome of sperm, making it difficult for female babies to be born; low temperatures can affect the Y chromosome of sperm, making it difficult for male babies to be born.
Therefore, to have a boy, it is best to conceive in summer; to have a girl, it is better to conceive in winter.
However, this is also not sufficient scientific evidence.
Tip 5: Posture and Frequency of Sexual Intercourse. If you want to have a boy, you can adopt a standing or backward position. After sexual intercourse, lie down quietly for a while. If you want to have a girl, you can try the missionary position or the upper female sexual position
Additionally, it is said that frequent sexual intercourse can increase the likelihood of having a girl
Secret 6: The older the age of childbirth, the more likely it is to have a girl. The older the couple, the higher the chance of having a daughter. This is an undeniable reality
Due to the influence of age on the essence of both male and female bodies, the sperm count of males decreases with age, while for females, as they age, changes in psychological hormones also lead to a decrease in alkaline excreta in the uterus year by year, greatly improving the timing of giving birth to girls
Having a boy or a girl is just a matter of probability, and there's no significant correlation with age.
However, from the perspective of eugenics, couples should conceive a child at their optimal reproductive age.
The optimal age for women to have children is between 23 and 30, with men being between 30 and 35. Women should not exceed 30 years old, and men should not exceed 35 years old.
