Renewal period in men and women: how to calculate it

There are theories according to which the cells of the body, including blood, are periodically renewed. According to one of them, this biological fluid in humans changes every seven years, regardless of gender. According to another, more common one, it is believed that blood renewal in men occurs every four years. It changes a little more often in women - every three years. The process is cyclical and continues throughout life. Thus, each person can determine by their age when the last update was and when the next one will be. According to one theory, the count should be made from birth in men and from the first menstruation in women. According to another, from the age of 15 for women, and from 16 for men.

What does science say about conceiving a boy?

To understand how to properly conceive a boy, you need to know the principle of gender formation during egg fertilization. A new person receives half his DNA from his father and half from his mother. Moreover, as is known, women are carriers of the XX chromosome set, and men are carriers of XY. The future sex of the child depends on which father's chromosome is transferred by the sperm that fertilizes the egg. If the sperm carries the Y chromosome, a boy will be born[1].

Pregnancy with your son is the result of many factors coming together, so try not to put too much faith in advice on how to conceive a boy. Today, only the IVF procedure can accurately guarantee the birth of a child of the desired sex, but the selection of an embryo by sex in Russia is carried out only according to indications - in order to exclude any hereditary disease transmitted through the female or male line[2].

How to speed up the natural replacement process?

If you don’t want to wait for natural blood renewal to conceive a healthy child, this process can be accelerated artificially. The simplest and most effective method of speeding up in this case is donating blood.

Plasmophoresis also gives good results, but in this case, to speed up the process it is necessary to undergo a full treatment course.

You should not try to replace blood by transfusion , since this method of stimulating renewal has very little effectiveness, but can lead to side effects and complications.

Further in the article you will learn how to determine the sex of a child by blood renewal in adults, and other methods for determining the sex of the unborn baby.

How to conceive a boy by ovulation?

There is a calendar method, which is based on the scientific fact that Y-sperm are less tenacious, but more active than X-sperm. According to this method, the ideal time to conceive a son is the day of ovulation and the day preceding it.

A woman thinking about how to conceive a boy will need an ovulation chart. To do this, you can measure basal temperature every day, use pharmacy ovulation tests, or monitor follicles using ultrasound. You can also navigate by the discharge, which becomes more viscous and white during ovulation.

It is worth noting that the studies that discovered the increased activity and shorter lifespan of Y-sperm were carried out in vitro (“in vitro”), and are now being questioned by some scientists[3], so do not expect a 100% guaranteed result.

Exceptions in theory

For women with a negative Rh factor, the principle of operation of the theory changes exactly the opposite. In this case, the sex of the child is determined by the parent whose blood is “older” (whose remainder after dividing age by the decimal update rate will be greater). There is an opinion that this exception applies in the case of a negative Rh factor in a man, but it has not been confirmed.

When the body loses a significant amount of fluid, the timing of its renewal changes. In cases of heavy blood loss, the starting point of the renewal cycle will change - it will begin not from the date of birth, but from the moment of this event. Such cases include:

surgery;
donation;
childbirth (bleeding after childbirth);
abortion;
miscarriage;
injuries.

When to conceive a boy in 2021 according to blood renewal cycles?

According to the blood renewal theory, men's blood is renewed every 4 years, and women's blood is renewed every three years. A boy is more likely to be born to the couple in which the father was the last to renew his blood. First, you need to calculate who currently has “younger” blood. The count is carried out either from birth or from large blood losses (after operations, injuries, childbirth or abortions).

We divide the father's full age by four (for example, if he is 29 years old: 29:4 = 7, remainder 1).
We divide the mother's full age by three (for example, if she is 26 years old: 26:3 = 8, remainder 2).
Let's compare the balances. In a man, the blood was renewed only a year ago (remainder 1), and in a woman - 2 years ago (remainder 2). Based on this theory, one can expect the birth of a boy during this period, since the blood of the future father is “younger.”

How blood is renewed

This issue is still being studied by scientists, its detailed features are being considered . The theory is still being tested through research. The blood renewal table, taking into account some features, is still being compiled by scientists.

Blood consists of cells that perform different functions:

Red blood cells.
Leukocytes.
Platelets.

Red blood cells are the most common blood cells

They do not have a nucleus, but they contain the protein hemoglobin, which contains an iron atom.
Thanks to this, an oxygen molecule is attached to the red blood cell. The amount of oxygen changes after it is released to the cells. These cells enter the blood from the bone marrow.

What you need to know about them:

They replace dead red blood cells.
They live 120 days.
There are most of these cells in human blood. They deliver oxygen to every organ.
The process of death of such cells occurs in the liver, spleen, but can also occur in blood vessels.

Leukocytes protection against viruses and infections

There are much fewer leukocytes than red blood cells. They perform a protective function: they prevent viruses and pathogenic bacteria from entering the body.

How the immune system works

There are several types of leukocytes:

Eosinophils. Protects the respiratory system, urinary tract and intestines.
Neutrophils. Ensure proper functioning of the immune system.
Monocytes. They function to eliminate inflammatory foci.
Basophils. Eliminate allergic and inflammatory reactions in the body.
Lymphocytes. Destroy viruses and pathogenic bacteria.

These cells live for about three months, then they die and new ones appear in their place.

Platelets wound healing

These cells are responsible for the integrity of the walls of blood vessels and their rapid restoration in case of damage. If a person is injured, it is these cells that lead to blood clotting. They prevent major blood loss. They originate in the bone marrow and then enter the bloodstream. They live for ten days, after which they die and new ones appear in their place.

Platelet functions

Platelets can have different sizes:

Microforms – 1.5 microns.
Standard forms – 3 microns.
Macroforms – 5 microns.
Megaloforms – 8-10 microns.

What diet should you follow to conceive a boy?

Some studies have found a connection between nutrition and the gender of children born. Expectant mothers and fathers who want to give birth to a son are advised to eat foods rich in sodium and potassium - meat, sausages, fish (but not other seafood), potatoes, peas, lentils, beans, mushrooms, cherries, bananas, apricots, oranges, peaches, dates, egg whites, rice, semolina, cookies, dark chocolate. In this case, it is better to give up milk, bread, mineral water with calcium, nuts, greens, green beans, cabbage and salt food more than usual.

If the future parents had significant blood loss

In this case, the general cycle of blood renewal is shifted. Every serious blood loss leads to the fact that the body is forced to restore losses in an emergency mode, throwing all its hidden resources at it. In such situations, blood cells of all categories begin to be produced in large quantities, resulting in unscheduled renewal.

For this reason, when determining the sex of a child by blood renewal, it is important to take into account all such points. In this case, it is necessary to count from the date of the event, as a result of which significant blood loss occurred.

What other methods are there to conceive a boy?

They say the following tips may work:

quit smoking;
try not to reduce your weight below 55 kilograms;
give in to your husband - he must be the de facto head of the family;
don’t worry if you can’t get pregnant for a long time - the longer you don’t succeed, the higher the likelihood that you will have a boy;
lead a calm, measured lifestyle, avoid stress;
visualize your future son in every detail.

And finally, a few folk methods to conceive a boy. It’s good if conception occurs in the summer, but it is important that the future father walks the earth barefoot, renewing and strengthening his masculine energy. It is believed that the best time to conceive a son is the morning or afternoon of Monday, Tuesday, Thursday or Saturday.

Update calculation

Many health-conscious people ask their GPs if it is possible to calculate when blood vessel turnover begins.

Keep in mind that each person's recovery cycle is slightly different. Also, the period of hematopoiesis largely depends on the anatomical features and the influence of external factors. If a person is a donor, recovery will be more frequent and faster, this will be an individual trait.

International medicine believes that in men and women the biomaterial is renewed in the following way:

If the Rh factor is negative

If a woman has a negative Rh factor, then in this case the calculations change somewhat, since older blood will be dominant in such a situation. It is she who will determine the gender of the unborn baby.

Considering the above example of calculations for negative Rh blood, we can conclude that the couple will have a boy, since the remainder 75 is greater than 3. With negative Rh, the sex of the baby is determined by the largest remainder of the values obtained in the calculations.

Some experts claim that the Rh blood of not only women, but also men is important. And if the father of the unborn child is Rh negative, then the calculations also change and the oldest blood at the time of conception becomes dominant. But there is no scientific confirmation of this.

Herbal cleansing

It has long been known how to cleanse the blood and body well with herbs. To rid the blood of toxins, you need to take a mixture of herbs - tricolor violet, strawberries, add black chestnut leaves (4 small spoons each). Brew glasses of boiling water.

Parsley helps a lot. During the season you need to eat more of it. The seeds are also used for cleaning. Stir 1 small spoon in half a liter of water. Then leave for 10 hours, drink 100 ml three times a day.

The root of this amazing plant helps. You need to take two large spoons of dried crushed root, 300 ml of boiling water, leave the mixture for 3 hours, strain thoroughly. Drink a large spoon before each meal for about 14 days.

Probability of success

Many people know that there are now quite a few methods to help determine the gender of the unborn child, including various online tests. However, all the glory went to the blood renewal method. Despite such success and many positive reviews, no one can confirm its effectiveness one hundred percent. In addition, this method is not supported by any research, so it is quite difficult to judge its effectiveness in practice. If you look at things realistically, then the probability of success when calculating does not exceed sixty percent, and in some sources you can even see the figure of 50%.

The method when parents just need to calculate in which year their blood was renewed is simple, but it still does not provide any guarantees for a reliable forecast. Experts believe that those couples whose pre-calculated result coincided with reality were accidentally lucky - and this is a fact that has scientific confirmation. In other words, if at the time of conception the male sperm contained a set consisting of X chromosomes, then a girl will be born. If there was one child chromosome in the male cell, then a boy will be born. As a result, only one conclusion arises that does not require any refutation - blood renewal does not affect what gender your child will be.

When choosing this method, which, according to most, helps to plan the gender of the unborn child, do not forget to take into account all external factors, as they can influence the final result. And don’t forget that you can find out exactly the gender only by signing up for an ultrasound, which is usually performed at the twentieth week of pregnancy.

You shouldn’t place much hope in a method or test that uses the parents’ blood renewal as the basis for determining the baby’s gender, since judging by medical research data, its reliability is very doubtful

In the end, it doesn’t matter so much whether you have a boy or a girl, the most important thing is that the child is healthy

Peripheral blood in premature infants

The red blood of a healthy premature baby at birth is characterized by erythroblastosis, reticulocytosis, increased red blood cell and hemoglobin counts, as well as anisocytosis and poikilocytosis. Soon after birth, there is a gradual drop in the content of red blood cells and hemoglobin, and by the 2-3rd month of life, most preterm infants develop anemia, known as “early anemia of prematurity.” Its pathogenesis is based on increased hemolysis and functional immaturity of bone marrow hematopoiesis. The cause of intense hemolysis is the predominance of unstable red blood cells containing fetal hemoglobin in the blood of premature babies.

Thus, in healthy premature infants, anemia in the 2-3rd month of life can be considered as a manifestation of adaptation when replacing extramedullary hematopoiesis with bone marrow. In sick children, early anemia is often accompanied by more pronounced changes in the content of red blood cells and hemoglobin and has a long course.

By the beginning of the 4th month, there is a spontaneous increase in the level of red blood cells and hemoglobin, but a month later there is a repeated decrease in levels and late anemia of prematurity develops, caused by a lack of iron in the body. Unlike early, late iron deficiency anemia can be prevented and effectively treated with iron supplements.

How quickly does sperm recover completely?

For complete recovery of sperm, it takes from 68 to 78 days, that is, approximately 2.5 months. Of these, from 56 to 64 days are required for the transformation of spermatogonia into sperm, and another 12 to 14 days for sperm to mature in the seminal appendages. This means that if a man has been exposed to factors that negatively affect spermatogenesis (taking antibiotics, overheating, etc.), then conception should be planned no earlier than 3 months after their elimination.

Also, when planning conception, it is important to understand how much sperm is restored after sexual intercourse. After ejaculation, new sperm mature and emerge from the epididymis within 72 hours (3 days). Therefore, the optimal frequency of sex for a couple who is trying to conceive a child is 2 times a week. Otherwise, immature sperm will end up in the sperm, which have little chance of fertilizing the egg.

List of useful products

Many experts advise future parents to improve the quality of their blood before a planned conception, for which they should follow a certain diet, giving up junk and heavy foods and enriching their diet with healthy foods, in particular, you should add to the daily menu:

Fresh beets and carrots , eating them raw or in juice form.
Fresh garlic . Doctors recommend swallowing a clove of garlic every day before going to bed. In this case, all processes of hematopoiesis are significantly accelerated in the body.
Fish of marine varieties , since almost any of them contains omega-3 fatty acids, which contribute to the qualitative improvement of the blood, its purification and the removal of cholesterol from it.
White cabbage . It should be consumed fresh, without subjecting it to any heat treatment, as in this case it loses all valuable substances. It is best consumed as part of fresh vegetable salads.
Fresh apples of different varieties , best of all those that grew on your own plot, since they will not contain any chemicals, which cannot be said with certainty about a store-bought product. When choosing apples in a store, you should give preference to the most inconspicuous fruits that have a natural color and appearance.
Pomegranate seeds , as they also contain a huge amount of vitamins, many of which are necessary to improve hematopoietic processes.
A variety of nuts , especially walnuts and hazelnuts. Nuts contain a significant amount of potassium, magnesium and iron, as well as many vitamins and therefore can influence renewal processes.
