The sex of the child by blood

Blood washes all parts of the body, and its cells reflect the situation in the body, they are indicators of health. The proteins in their composition carry genes that are passed on to the child during mating and paternal DNA. The composition of blood changes daily: some cells age and die, new ones appear instead. Therefore, in each certain period of time, fresh or old units prevail in the structure.

Cells are reborn cyclically. It has been established that in the female body the process occurs every three years, and in the male – every four. Counting time updates need from the time of puberty rights. For women, it is customary to count from 12 years, for men from 16 years. Therefore, the calculation uses the following progression for the female: 12, 15, 18, and so on, and for the male – 16, 20, 24.

How to find out the sex of the child by updating the blood?

It is believed that more young blood brings to the new cell – the unborn child – stronger DNA, which means it determines its sex. For example, a couple at the age of 28 found out about pregnancy. By calculations, we determine that a man’s blood has been renewed at 28 years old, and women a year earlier, because he is older. According to preliminary calculations, the pair should expect a boy. However, the method requires accuracy in the definition. The calculators offered on the sites suggest entering the year, month and date of birth of a man and a woman, as well as the date of conception, which is not always known.

Controversial points of the blood renewal method

Only with an extraordinary striving to conceive, keeping a schedule of basal temperature and a calendar of sexuality, can a woman name the date of conception. Fertilization can occur over seven days after ovulation. Signs of egg maturation – indirect or calculated. Therefore, more often than not, women can either plan the sex of the child according to the method in advance, or make a very inaccurate calculation of the approximate information.

If a man and a woman are approximately in the same phase of blood renewal, then the method actually loses its strength. For example, a woman of twenty-seven years old and a man of twenty-eight years old will not know whose blood is newer if they were born on the same day. Although this case is rare, it perfectly illustrates the fact that the determination of the sex of a child for blood renewal is based on assumptions.

Abdominal surgery, large blood loss, blood transfusions can also serve as starting points for blood renewal, which once again proves the inconsistency of fixed time intervals.

Other tools for the blood renewal method

Some scientists develop complex tables with percentages of the probability of having a boy or girl, given the blood type of the father and mother. However, there is a simplified method. If a woman has the first blood group, the combination with odd groups of the man increases the likelihood of the birth of a girl, and with blood 2 or 4 groups of a partner – the birth of a boy. But this method shows inaccuracy on the example of large families in which children of different sex are born.

Do not forget about the existence of a positive and negative Rh factor for any blood type. It is believed that if both parents have a positive or negative rhesus, then a girl will be born. Boys are often born at different values ​​of Rh factors. Women with negative rhesus blood should be especially attentive to the planning of conception and childbirth, since the risks of Rh-conflict increase if the fetus has a positive group. Accuracy is not guaranteed by this method either, since it has no statistical evidence and scientific evidence.

Opinion of obstetricians and gynecologists

Health workers question the renewal of blood in general, and, especially, the planning of the sex of the unborn child. The calculated indicators of starting age and time intervals do not have a scientific basis, are based on averaged data on the age of puberty. Averaged calculations are accurate to 50%. Updating blood does not occur on the calendar, but depends on lifestyle, illness, stress, physical activity and hormonal status.

Determining the sex of the child by maternal blood

Back in 2011, scientists from the United States invented a simple blood test of a woman, according to which sex can be determined on the 7th week. The technique is based on the purification of free-floating DNA and the search for Y-chromosome, indicating the conception of the boy. The test was designed to detect chromosomal developmental abnormalities, suspected hemophilia in boys, as well as congenital adrenal hyperplasia, which is associated with early puberty. The analysis was tested on 6,500 pregnant women participating in 57 studies over 15 years. Perhaps soon this test will be available in all diagnostic centers in the world.
