The probability that a boy or girl will be conceived from the point of view of science is the same. But there are "rules", following which you can give birth to a child of the sex you want, these are methods that are applicable before conception.To determine the sex of the child there are also ways after conception.Many of these methods have no scientific basis, others in general are people's perceptions and fortune telling.The main thing is not to let the birth of a child of a certain gender become an obsession for you, because the most important thing is that he is born healthy.
First, consider the methods before conception. The first way to determine the sex of a child is associated with ovulation. Y-chromosomes move faster and in the period of ovulation first reach the oocyte. Then the probability of a boy's birth increases. Before ovulation, unfavorable conditions are created for the Y chromosomes, and they die. X-chromosomes reach the ovum and more likely the birth of a girl. Ovulation occurs on the 14-15 day of the menstrual cycle, which usually lasts 28 days. This method proved to be the most reliable in practice.
The second method is associated with a certain diet, or diet. To conceive a boy, one must eat fatty foods, but with a small carbohydrate content, this includes products with a high content of potassium and sodium, and a low content of calcium and magnesium (smoked meat, peach meat, potatoes, legumes). For the girl, it needs a small amount of potassium and sodium, and a lot of calcium and magnesium (greens, dairy products). But while this experience was conducted only in mice and was successful in two of three cases.
The sex of the child, perhaps, depends on the frequency of sex. If the couple does not depart from each other, then most likely there will be a boy. If there was a sufficient break in sex or the relationship is not sufficiently fervent, then most likely there will be a girl.
Another method to determine sex depends on the blood of the parents. Update of blood occurs in men every three years, and in women - once every four years. Whose blood is newer, that sex will be a child. It is necessary to calculate from the date of birth of future parents. But here you need to consider all the blood loss, including blood loss during menstruation and surgery. Although this method is quite reliable, but it is very easy to make a mistake.
Also the sex of the child can depend on the age of the mother. Young mothers are most often born boys (approximately 55%). A woman after 30 is more likely to give birth to a girl (53%). Girls are more enduring and the more weakened organism of the mother nature sends it more often.
The greatest probability of the birth of a boy during the first birth. With each successive this probability is reduced by 1%. If the father is much older than the mother, then most likely the birth of a boy, and, conversely, young fathers often have girls.
Now consider ways to determine the sex of the child after conception. First, it is medical research. During pregnancy, any woman has ultrasound (ultrasound). The whole procedure takes 5-10 minutes, the doctor determines the term, the position of the fetus and the placenta, how well the child develops normally. Determine the sex can be already at 14-16 weeks, unless the child is hiding.
Prenatal diagnosis can provide reliable information about the child's field. This method consists of penetration into the uterine cavity, investigation of amniotic fluid, the study of the chorion and collection of umbilical cord blood. The object of research is the chromosome set of the child. This is a serious procedure, poses some risk for the child, so it is carried out only according to the doctor's prescription.
There are also non-medical methods to determine the sex of the child. For example, if the mother has a strong pulse in the area of the ring finger on her right hand, then a boy will be born if the girl is on the left.
You can also observe the behavior of a pregnant woman. If the first three months passed without complications, there were no problems with the appetite, and she in every possible way showed her stomach, proud of the fact that she would soon become a mother, said that there would be a boy. If pregnancy starts badly, mommy does not eat well, and is embarrassed by her abdomen, worried because of the loss of beauty, then there will be a girl.
They also say that the girl takes away the beauty of her mother, and with the boys, on the contrary, women become more beautiful every day. Fathers say that bald men are more likely to have boys.
Previously, the sex of the baby was determined by the shape of the abdomen. If the stomach is big and sharp, it means that they were waiting for the boy, And if it is flat, then the girl. Although this method is not confirmed by modern doctors. They say that the shape of the abdomen does not depend on the sex of the child, but on the structure of the mother's pelvis. If the pelvic bones are narrow, then the stomach will be large and sharp.
