Is it true that these 5 things affect the sex of the unborn child?

A boy or a girl? This question interests not only the pregnant woman, but also the future daddy, and also all nearest relatives and friends. He was asked at all times, and in our age of advanced technology nothing has changed.

Technologies in the modern world are developing at a tremendous speed, this also applies to ultrasound devices. Doctors with an accuracy of 100% determine the sex of the baby. They resort to ultrasound not only in the case when it is necessary to find out who will be born. It is necessary to undergo research in order to identify various diseases of the infant at a short time or to make sure of its health. According to statistics, the ratio of born boys and girls is 50/50. Scientists hypothesize that there are certain factors affecting the sex of the baby.

In Vitro Fertilization

Researchers from Australia argue that the sex of an infant, conceived with the help of reproductive technology, depends directly on the method. The proportion of newborn boys fell to about 49%, when couples selected a fetal egg for this procedure at the stage of crushing, that is, two or three days after fertilization. The percentage increased to 56 with standard in vitro fertilization, when the embryo is placed in the uterus four days after the formation. The exact cause is unknown. Most likely, this is due to the length of time that the embryo conducts in the laboratory.

Diet

Research conducted in 2000 says that women who generally consumed more calories ate porridge rich in potassium for breakfast, mostly gave birth to boys. French scientists even developed a special diet, which has the same name. A woman should eat foods saturated with potassium and sodium in order to conceive a boy. But the answer to the question, whether it is safe for the health of the future mother, remains unresolved.

Do not assume that if you reduce the number of calories, then you will have a girl in the family. Most importantly - the expectant mother should eat right, be healthy.

American scientists put forward the theory that a woman before conception must eat dairy products, lean meat, fresh fish and fruits, and berries to become pregnant with a girl. It is necessary to avoid yeast, salt and pickled products. The body is saturated with calcium. However, do not forget that the food should be balanced and complete, so that the baby is born healthy.

Scientists have not proven that various diets will form the sex of the baby. First of all, you need to follow the recommendations of your doctor. Pregnancy is the time when the body needs a special diet.

Family stories

People often try to guess the gender of the baby, based on the number of boys and girls born before. And when suddenly a girl appears in the family, where before only four boys were born for four generations, the theory comes to naught. In fact, there are some families with a certain genetic predisposition. But published studies confirming this, no. The available data indicate that this is just a coincidence.

Terms of conception

The sex of the baby can also be influenced by the time of conception. There is evidence that the closer sexual intercourse to ovulation, the more likely to give birth to a boy. This is due to the fact that the spermatozoa that carry the Y chromosome live less and are more mobile than the spermatozoon with the X chromosome. Therefore, if you want to conceive and give birth to a girl, it is better to schedule sexual intercourse 3-4 days before ovulation. This theory can also be questioned. In 1995, British scientists conducted a study and found no evidence of this theory.

Level of stress and wealth

In 2013, scientists from Greece conducted a study, which revealed that within two years after the earthquake on the island of Zakynthos, the male fertility rate fell several times. The researchers suggest that the more fragile Y-chromosome could not survive during periods of high psychological stress. Thus, it can be concluded that stress can affect the level of hormones in the body of a future mother.

Scientists from Oxford University conducted their research. They came to the conclusion that women who were subject to constant stress before conception are more likely to give birth to a girl. The so-called stress hormone does not allow the male embryo to enter the uterus. Do not forget that the sperm with the Y-chromosome under stress is living very little.

Also in 2013, one of the secular publishers published a theory that says that boys often appear in the family of a wealthy heir. Most likely, the fact is that men who did not have to work hard to get huge money, are less stressed. However, this is just a theory, it has no scientific justification.

To minimize stress, future parents who want to give birth to a boy can do yoga.
