Conception of the boy - a scientific approach

Most "popular" ways of predicting andplanning of the sex of the unborn child do not have a scientific justification. Positive results obtained with observance of "people's" assumptions and methods, most often have a random character. Therefore, the conception of a boy is best planned with a scientific approach.

According to fertility statistics, there are 106 girls on average for 100 girls. This is due to the high mortality rate of the stronger sex and the viability of women.

The scientific methods of conception of a boy arereasonable combination of a certain set of chromosomes of spermatozoa in men and chromosomes of the egg in women in the process of fertilization. The fact is that the sperm and the egg contain 23 chromosomes, including 22 somatic, and one, which determines the sex of the child.

In women, the ovule always contains only the X chromosome that determines the sex of the baby. In men, spermatozoa can contain both X and Y chromosomes.

The fusion of germ cells forms an individualgenotype: male (46 XY) or female (46 XX). That is, the sex planning of the child is determined by the combination of sex chromosomes. If the combination of chromosomes is XY, then a representative of the stronger sex will be born, if XX is a girl.

Thus, the responsibility for conceptionthe boy lies entirely with his father, since the formation of the sex of the unborn child depends on the male sexual cell. And the methods of scientific determination of the sex of the baby at the moment of conception should be based on the properties of this particular sex cell.

There is a difference between X and Y spermatozoa. Spermatozoa with an X-chromosome are larger in size, more viable, but considerably slower than gametes with Y chromosome. These methods of male sex cells are based on the method of planning a child by the date of ovulation of the egg.

If the sexual act for the conception of the baby occurs fora few days before ovulation, the probability of conception of a girl increases dramatically, as in the genital tract of a woman will remain only the most hardy and viable spermatozoa containing the X chromosome. They will be fertilized just appeared egg.

The conception of a boy can be realized ifabstain from sex until the day of ovulation for at least a week, and the sexual act to be performed on the day of ovulation. Then more "nimble" Y-spermatozoa will outrun the X-spermatozoa and, the strongest of them, will first penetrate into the ovum.

This scientific justification justifies the "people's"approach to sex planning in conception of a child, which is the sexual activity of partners. If you have sex more often, then a representative of the stronger sex will be born, and if you often refrain from sex for several days, a girl will be born.

The probability of giving birth to a boy can be influenced byother scientifically grounded factors. For example, an acid-alkaline environment in the vagina. The fact is that before ovulation the pH in the vagina is more acidic. Therefore, spermatozoa with a male Y chromosome quickly die. On the day of ovulation, the acid-base medium changes toward alkalization, more comfortable conditions are created for the Y-spermatozoa, and the conception of the boy.

If a woman does not know exactly her ovulation day,then it must be correctly determined by a basal temperature, ovulation test, or ultrasound. Observations of the onset of this process should be carried out for several menstrual cycles. According to their results, a woman can learn to feel ovulation without resorting to technical means, for example, feeling pain in the lower abdomen, nausea, abundant secretion of mucus from the genital tract.

Thus, the conception of a boy mustFollow 7-10 days of abstinence from sex during ovulation. Then the probability of the fact that it is the sperm containing the Y chromosome that will reach the egg first will significantly increase and penetrate into it, giving rise to a new life.
