What determines the sex of the child

Many know that the sex of the unborn childis established in the process of conception, and first of all it depends on which sperm the egg will be fertilized. The girl is obtained from the sperm carrying the X chromosome, the boy is from the spermatozoon with the Y-chromosome. The question remains, is this connection random, or can it be influenced by it?

Since ancient times, the question of what the sex depends onchild, excited many people. There are many different ways to influence the sex, but most of them are based on superstitions and prejudices. But, there is also such information, which is worthy of attention. Therefore, you should not categorically assert that it is impossible to plan the sex of the child.

Theory of determination, on which the sex of the child depends

Statistics say that most of the time boysFirstborns are born, with subsequent birth, the probability of their birth is reduced. Similarly, young parents have a better chance of conceiving a male child, and vice versa, respectively. People suffering from gout are mostly girls.

In addition, there is information that children with smallthe difference is often born the same sex, if the birth occurs at an interval of more than three years, then in most cases children are born unisexual. If there is a short time between abortion and pregnancy, the girl is likely to be born, and so on. This is only a small list of assumptions on which the sex of the child depends.

Gynecologists with extensive experience cantell bad stories, when the sex of the child was the reason for the divorce in the family. Very often mothers have to listen to reproaches that they are not able to conceive a son. But even from the lessons of biology we know from what depends the sex of the child - exclusively from a man, and in particular from his spermatozoa.

If women could do without male participation in the conception of the child, then only girls would live on earth, since the egg carries only the X chromosome.

The difference between the X and Y chromosomes

Spermatozoa with the X- and Y-chromosome have somedistinctive features. The X chromosomes are more tenacious, and the Y chromosomes are lighter and more mobile. On the basis of such information, theories appeared that during the conception before ovulation the Y chromosome perishes and the egg fertilizes the X chromosome, and as a result, a girl will be born.

But if conception occurs after ovulation orduring it, then the Y-chromosomes will be faster and the boy will be born. Such conclusions are confirmed by various studies that were conducted on the topic, on whom the sex of the child depends.

But sperm are able to fertilizeovule at a certain time limit. Goal must be completed within 24-46 hours. After such a period of time, the egg dies. If conception does not occur, then you will have to wait for the next favorable cycle. As scientists explain, this development is due to a change in the acidity of the environment. The closer the ovulation, the more alkalies contain secretions from the genital tract of a woman.

When it is important to know the gender of the unborn

In some cases, the sex of the child still hasof great importance, since there are certain diseases that are transmitted to a child of a certain sex. Such diseases include deafness, mental retardation, hemophilia and so on. If there is such a risk, the future mother must undergo the procedure for establishing the sex of the unborn child. In other cases, determine the sex of the child before his birth or not, parents decide.

The exact method of establishing the sex of a child

Practically with a 100% guarantee you can installsex of the child with the help of a chorion biopsy. But this method is very risky and can contribute to the development of complications and even termination of pregnancy. You can set the sex of the child in this way starting from seven weeks of pregnancy. Usually, such a procedure is carried out according to the prescription of the doctor, the exception is the mother, who already has three children of the same sex.
