How to plan a floor?

It seems that nature in terms of choosing the floor for the future baby is absolutely adamant. No matter how much the parents want to bring up a son or necessarily a daughter, the final word is still beyond the unknown higher powers. Nevertheless, science has long wondered how to plan for the future sex of a child, and great minds made a number of discoveries on this topic. Today future parents are also interested in them in the hope of deceiving Mother Nature. About what these methods are, read further in the article.

New blood

It is believed that in women the blood is renewed every 3 years, and in men - every 4. In this case, if a person has experienced a serious operation or blood loss, then the countdown will start from the date of this event. The age or period from the last blood loss is divided by the males by 4, and by the female by 3. If the mother has Rh-negative blood, then the opposite is true - in the denominator, the men will be 3, the women - 4. The one whose when dividing more - mother or father's - has a more "young" blood, and is able to transfer its gender to the child.

Word science

This method has not received scientific justification. After all, science has long been proven: the sex of the future baby is entirely dependent on the man. The fact is that male and female sex cells contain a half set of the gene material - chromosomes. There are 23 chromosomes in one spermatozoon and egg cell. When cells merge, an individual genotype of the future person is formed - 46 XX (for a girl) or 46 XY (for a boy). In a woman, the eggs contain only one X chromosome, and the male spermatozoa are found in two types: with the Y chromosome and with the X chromosome. When an egg cell fertilizes, the first (Y) chromosome will give birth to a boy, the second (X) - a girl. So, to torture a woman with folk and non-popular ways - to calculate the age before conception, to sit on some kind of diet, to check the date and month of birth is completely pointless.

How to schedule sex by ovulation

X and Y spermatozoa are different. The first one is bigger and sturdier. The latter, on the contrary, are lighter and more mobile, but less stable. You can fertilize an egg after it leaves the ovary (ovulation). If sex was before ovulation, the probability of the birth of a girl is higher: in the female genital tract only the hardy X-spermatozoa are left to wait for the egg cell.If sexual intercourse took place on the day of ovulation, the likelihood of the birth of a boy increases: motile Y-sperm will outrun "X-mates."

Sex frequency and sex of the child

Is it possible to plan the sex of the child through frequent sex? With high sexual activity (we are talking about daily sexual intercourse or sex every other day), boys are more often born. It is believed that Y-spermatozoa in this case will reach the goal much faster. Accordingly, the lower the sexual activity, the more chances for the birth of a girl — the work on her conception is acquired by surviving X-spermatozoa for 4-5 days. The effectiveness of this method is proven in 80% of cases. The main thing is to guess with ovulation.

Sperm division

How to plan the sex of the child, dividing the X and Y-sperm? This procedure is done by specialists in family planning centers. Sperm cells are first stained with special dyes, and then separated in the electric field using laser technology. Fertilization of the egg is produced in a test tube with the necessary sperm, an embryo of the necessary sex is obtained, and then it is introduced into the uterus.But even this, fully and fully justified method does not provide a 100% guarantee.
