The conception calculator for boys and girls will help you determine the most appropriate time to conceive a child of your desired gender based on the date of ovulation.
Pregnancy, future motherhood and fatherhood are among the most important events in life. After receiving the news about the imminent replenishment, parents are always tormented by the question: who will be born? Girl or boy? Since ancient times, there have been many methods and signs for sex determination, but none of them guarantees a 100% result.
How does a boy become conceived?
The discovery of female and male sex chromosomes, which determine the sex of the child at the time of conception, dates back to 1905 and belongs to geneticists Nettie Stevens and Edmund Wilson. The X and Y chromosomes inside the sperm must reach and penetrate the egg. This process is influenced by numerous factors.
Sperm that carry the female chromosome are more resilient and retain motility longer.
Scientists have found that sperm carrying the X chromosome (female) are able to maintain mobility longer. But those with the Y chromosome, who are “responsible” for boys, move more actively.
Therefore, if conditions are created in a woman’s body for sperm to quickly penetrate the uterus and its tubes, the likelihood of fusion with the egg of a “boy tadpole” will increase. What methods of creating such conditions are known to modern science? Let's look at them.
Calculation by ovulation
The most scientifically proven way to conceive a boy is to count the days of ovulation and have sexual intercourse on that very day or the day before ovulation.
This is due to changes in the chemical composition of a woman’s internal environment before, during and after ovulation, which affects the X and Y chromosomes differently. A female germ cell carries only an X chromosome (feminine), a male germ cell can have a Y chromosome (female) and a Y chromosome (male). When the XX chromosomes fuse, the result will be a girl, and the XY chromosomes will result in a boy.
Before ovulation, the chemical composition of a woman's genitals changes to favor the sperm carrying the Y chromosome. Such germ cells are more mobile, mobile, tenacious, in contrast to female sperm. Therefore, the most accurate method is to count the days for conception based on ovulation.
Ovulation calendar
To know exactly the time of ovulation, you need to draw up a specific calendar, which will indicate the start and end of menstruation, the time of possible conception and the day of ovulation.
Better days
The female egg matures in the follicles. When it is ripe, the follicle bursts and the egg enters the abdominal cavity.
Her life lasts from 24 to 48 hours, that is, a maximum of 2 days. The life of sperm in the cavity of the female organs lasts from 2 to 4 days, and although male cells are more fidgety than female ones, they die faster than female ones.
How many days before ovulation does pregnancy occur with a boy?
Since carriers of male chromosomes are more adapted to survive in an unfavorable environment, they will have a better chance of not dying and getting to the egg first, so it is advisable to try to have a boy on the day of ovulation or the day before it.
Of course, there is a chance to conceive a girl in the preovulation period, but for Y chromosomes the chances are greater.
How long after ovulation
The chances of getting pregnant with a boy after ovulation are extremely low.
Since the egg lives for 24, maximum 48 hours and sexual intercourse occurs on this day, then fast sperm will be able to reach it within 24 hours and pregnancy will occur. Only when the egg retains its vital activity can the X and Y chromosomes fertilize it. When the life of the egg ceases, fertilization becomes impossible.
Calculation example
The method cannot be given a 100% guarantee for one reason: the displacement of the female cycle. It’s enough to get nervous or get sick, and menstruation will begin a few days earlier or later than expected.
Considering that 14 days pass between ovulation and the first day of menstruation, then a woman will have no way of knowing when this will happen. Only special tests can give an accurate answer to this question.
You can also use the ovulation calculation chart. It is based on fluctuations in basal temperature. Every morning, without getting out of bed and without making sudden movements, the temperature of the anus is measured and entered into the table. To determine a regular ovulation cycle, the numbers are recorded for at least three months. The graph should look like this:
- the top line indicates the days of the month;
- the bottom line shows the temperature (for example) from 35.8˚ to 37.5˚.
When measuring basal temperature, you need to put a point on the chart at the intersection of the lines of the day of the month and today's temperature. If the next day the temperature increased by 04.06 degrees, it means that ovulation occurred on that day.
Planning the right time for conception
Ovulation is the period in the menstrual cycle when an egg is released from a mature follicle into the fallopian tube for fertilization by a sperm. It is during this period that sperm carrying the Y chromosome are much more likely to fertilize an egg, thereby increasing the likelihood of conceiving a boy.
Why? It's simple: Y-sperm are active and light, but not hardy. Sperm with a female chromosome are heavier and more resilient, so they are more likely to fertilize an egg in the future.
To conceive a boy, sexual intercourse must take place on the day of ovulation.
Therefore, in order to conceive a boy, sexual intercourse must take place exactly on the day of ovulation. If you have sex a few days before its onset, the persistence of “male” sperm may not be enough until fertilization. In addition, the survival of Y-spermatozoa is also facilitated by the alkaline environment, which appears during this period and intensifies during female orgasm.
There are many ways to calculate the day of ovulation: special tests (similar to pregnancy tests), measuring basal temperature, ultrasound monitoring of the ovaries, calendar calculation.
To calculate the day of onset of ovulation, you can use a special test
Ovulation usually occurs 14 days before the end of the cycle. To calendar calculate ovulation for a boy, you need to subtract 14 from the longest and shortest cycle over the past year. The period between these dates is the most favorable for getting pregnant. Approximate calculation according to the calendar: if the cycle is 28 days, then ovulation occurs on the 14th day, 30 days on the 16th day, etc. From a scientific point of view, this conception option is quite justified and effective, and it is undoubtedly , is worth taking note.
Calendars for determining the gender of a child
Considering this method, we will immediately make a reservation about its scientific validity - it is absent. The probability of conceiving a boy according to both the Chinese and Japanese calendars is 50%, that is, as with the usual unplanned option. Nevertheless, let's figure out what the ancient Chinese and Japanese offer us.
Chinese calendar
More than two centuries ago in China, a table was used to produce an heir in a noble royal family. It is very interesting that the calculations from that calendar table coincided, no matter how ironically the skeptics treated them. And the most unexpected thing is that it is in China that today it is forbidden for pregnant women to test the sex of their unborn baby.
The Chinese table is a calendar by which you can plan the gender of a newborn. This ancient manuscript was found by archaeologists in Beijing.
The table was invented by ancient sages. It is compiled taking into account the influence of the phases of the moon and a woman’s menstrual cycle, which, according to the Chinese, determines who will be born - a girl or a boy.
An ancient Chinese table is a calendar that can be used to determine the gender of the unborn child.
The table is clear and easy to use, but there is one caveat: according to Chinese standards, the age of newborns is calculated from the moment of conception. If at the time of birth our child is 0 months old, then in China it is already seven or nine months old. This must be taken into account when determining the mother's age. That is, if at the time of conception the expectant mother is, for example, 25 years and 4 months old, then according to the table she chooses her age not 25, but 26 years.
Japanese version
The Japanese, who have also been concerned for centuries with the problem of planning the gender of the unborn child, developed their own similar calendar. It just works on a slightly different principle.
Determining the sex of a baby using the Japanese calendar is as easy as using the Chinese calendar. To do this, you need to know the birth months of the future father and mother. Then find the point of their intersection in the proposed table. A number will be indicated in this cell (intersection point). It needs to be remembered.
Determining the gender of a child using the Japanese calendar is as easy as using the Chinese calendar
Find the memorized number in the second table. Then - the month of conception. At the intersection of these two data you will find the gender of the unborn child.
The sex of the unborn child can be found out by finding the intersection of the number from the sex determination table and the month of conception
Moon calendar
Science has not proven the reliable influence of the Moon on the gender of the unborn baby. However, if you are sensitive to such judgments and trust astrology, it may be worth considering this option. Proponents of this technique claim that when the moon is in the male zodiac signs - Aquarius, Aries, Gemini, Leo, Libra, Sagittarius, the likelihood of conceiving a boy increases. And it is desirable that this happen on the 11th, 15th, 19th or 21st lunar day.
It is believed that if the Moon is in a masculine zodiac sign, the likelihood of conceiving a boy becomes higher.
Folk signs for pregnancy with a son
Popular beliefs have been formed over many years, when people noticed when and how they got a boy.
- It is believed that in order to conceive a boy, a man must take the initiative to have sex and be the first to experience orgasm.
- During orgasm, a man must penetrate the woman as deeply as possible.
- If sexual intercourse occurs under a new month, and not a new moon, there will be a boy.
- A boy is conceived in even years and odd months.
- There should be a toy for the boy under the pillow.
Beliefs of different peoples:
- Italians are convinced that an overweight woman has a greater chance of becoming pregnant with a boy.
- The Germans believe that in turbulent times (war, popular confrontations, unrest) more boys are born. They say that during the war there will be many girls without a partner, and in order to even out the balance, more boys will be born. They also believe that the stress experienced contributes to the conception of a male baby.
- The Japanese claim that non-smoking parents have a 33% increased chance of conceiving a boy.
Other aspects of planning a boy
In addition to determining the most successful time to conceive a boy, it is worth knowing other important points that can affect his success.
Sex positions, orgasm
As noted earlier, female orgasm creates an alkaline environment favorable for “boy” sperm . This is perhaps the only scientific help that determines the increase in the chances of conceiving a small man. Otherwise, the choice of position during conception and the obligatory presence of female orgasm can be attributed, rather, to folk methods, the effectiveness of which is questionable.
Diet
To conceive a boy, both the expectant mother and the future father must follow the diet.
Note that both the expectant mother and the future father must follow the diet. The key point is that the diet should contain food rich in potassium and sodium ions, that is, the emphasis is primarily on salty foods. However, do not forget about healthy and wholesome nutrition and moderation.
Basic principles of the diet:
- Meat: any.
- Fish: any fish and products made from it. Not recommended: shrimp, crabs, shellfish.
- Bread and pastries: all types of bread and cookies, sweets, but without milk and without yeast. Not recommended: pancakes, pancakes.
- Cereals: all grains, rice and pasta.
- Vegetables: potatoes, green beans, mushrooms, peas, corn, soybeans.
- Fruits and dried fruits: bananas, peaches, apricots, oranges, cherries, dried apricots, plums, dates. Not recommended: grapefruits, cherries.
- Sweets: dark chocolate, honey, jelly, jam. Not recommended: milk chocolate, creamy ice cream, sweet egg-based creams.
- Drinks: tea, coffee, fruit juices, carbonated drinks. Not recommended: milk and milk drinks, cocoa, mineral water with a high calcium content.
- Miscellaneous: pickles, olives, vegetable oils, margarine. Not recommended: cheese and dairy products.
Blood rejuvenation, group, Rh factor - will they help?
The method of planning the sex of a child based on the blood of the parents, which is quite common on the Internet, actually has no scientific basis and is not associated with periods of renewal of blood elements.
According to this technique, a woman’s blood is renewed every three years (starting from the age of 15), and a man’s blood is renewed every four years (starting from the age of 16). Taking this information into account, it is necessary to determine whose blood is “younger”. If the blood of the future father was renewed earlier, then a boy will appear in the family. And vice versa, if the mother’s blood is “fresh,” it means there will be a girl. As a result, parents can supposedly plan the appropriate period for conception.
The popular method of planning the gender of a child based on the blood of the parents has no scientific basis
Actually this is not true. Every second, millions of red blood cells are formed in the human bone marrow. They “live” in the bloodstream for about 120 days, and then are absorbed by other cellular elements of the blood, which are responsible for removing dead cells and foreign agents. The lifespan of other blood cells is even shorter:
- leukocytes - from two to 15 days;
- Hellenophiles - 15 days;
- basophils - two to four days;
- macrophages - two to three months;
- platelets - seven to ten days.
Therefore, the sex of the baby does not depend in any way on the renewal of the parents’ blood. The group or Rh factor is also not important.
How to conceive a boy: Chinese calendar and Japanese table
There are Asian tables that can be used to calculate the month in which you can become pregnant with a boy. Chinese and Japanese. Now they are very fashionable and many people have heard about them.
- Chinese table. It is based on the Chinese lunar calendar. And it only takes into account the woman’s age.
- Japanese. It consists of two tables. And the data of both is already taken into account. In the first, the number is calculated according to the birth months of the future parents.
And in the second, this number will already show the chances of getting pregnant boys in specific months.
These tables do not have any scientific evidence; these are just observations. They do not always show the same result, so which one to believe is not entirely clear. It makes sense to try to calculate for several familiar couples and compile personal statistics on which table turned out to be more correct.
Keep dreaming!
As an alternative method of conceiving a small man, we will focus on the psycho-emotional state of the parents . It is very important to mentally prepare yourself for the arrival of this new person in your life. Remember that reality is created by thoughts, we attract what we think about and what we want, the main thing is to unconditionally believe in it.
The psycho-emotional state of the expectant mother is of great importance for conceiving a child of the desired gender.
Before writing this article, I remembered the feelings and mood during my preparation for pregnancy. I can’t say that I wanted a boy, but there was one important point - I always knew with absolute certainty that I would have a son. I imagined pictures of our walks together, wondered what traits (both appearance and character) he would take from me or from my husband, I had already mentally let this little man into my life. I can’t say what ultimately influenced the result, but I am a happy mother of a wonderful little boy.
One hundred percent way: conceiving a boy using IVF
This method can confidently be called the most effective. Future parents receive from a medical institution providing IVF a 100% guarantee of the birth of a baby of the desired gender. With this method, embryos are tested for the presence of X and Y chromosomes before the embryo is implanted in the uterus, allowing the desired sex to be selected.
Conceiving a child of the required gender using the IVF method is the most effective way
Preparing for a sex selection procedure is no different from regular IVF, where a woman undergoes hormonal stimulation to produce as many eggs as possible. The collected eggs will then be fertilized in vitro with the partner's sperm to create good quality viable embryos for genetic testing. An embryo biopsy is done on the third day after fertilization of the eggs. Based on the results, only embryos of good quality and carrying the Y chromosome will be used to conceive a boy.
However, this method also has disadvantages - the procedure is expensive and, for ethical reasons, has been prohibited in our country since 2012. But if the finances of the future parents allow, you can always choose the appropriate clinic abroad.
Alternative Methods - Credibility and Principles
What women don’t do to find out whether a boy or a girl is growing in the womb! Here are the most popular ways that women use to find an answer to the important question of what the definition may be in early pregnancy.
Chinese table
Rumor ascribes ancient origins to this method; it is claimed that the Chinese used it literally until recently
Until the ban on the birth of a second child was lifted, for many it was important to give birth to a boy, because the son could continue the surname, the family business. This led to a certain demographic imbalance - in the Celestial Empire today there is a terrible shortage of women with an excess of men
The residents of China and historians themselves do not confirm that the Celestial Empire has anything to do with this table. It uses months according to the Gregorian calendar, and in the 14th century, to which the table is attributed, the Chinese did not know such a calendar, using the lunar and solar ones. The accuracy of the table does not exceed 50–60%, which is comparable to ordinary fortune telling - either a boy (50%) or a girl (50%). And therefore you need to treat the method lightly and naturally - as fun entertainment.
All you need to know is the month of conception and the age of the mother at the time of conception. In the “age” column, find the desired value, correlate it with the month the baby was conceived and get either “M” (boy) or “D” (girl).
By blood renewal
This method of calculating the sex of a child will require concentration and mathematical skills. It is based on the hypothesis of blood renewal, which implies that in a woman this happens once every 3 years, and in a man - once every 4 years. If there was an operation or blood transfusion, then everything is reset, and this event is considered the date of the last update.
The child, according to the hypothesis, should inherit the gender of the parent who had the last update. Doctors deny the blood renewal in question. When talking about renewal, experts mean hematopoiesis, which occurs in the bone marrow constantly, and not once every few years. Hematopoiesis has nothing to do with reproductive function and cannot even theoretically participate in issues of conception and the development of gender.
By fetal heartbeat
The heart is one of the first to begin functioning in a child’s body, and already on an ultrasound at 6–7 weeks, the doctor will confidently tell the baby’s heart rate. It is this indicator that many expectant mothers try to interpret as an indicator of the child’s gender. Good advisers from women's forums are always ready to explain that a rapid heartbeat is a sign that a girl is growing in the womb, and a measured, fast heartbeat is more typical of boys.
According to signs
There are a great variety of signs and signs of a child’s gender. This includes determination by the belly (belly with a “corner” - towards a boy, “with a ball” - towards a girl), and fortune-telling by the date of conception, by the day of sexual intercourse, by the age of the father. Determination by the abdomen is available only in the later stages, when the abdomen itself becomes obvious, and the method does not pretend to be truthful, since the shape of a woman’s abdomen depends on how the placenta is located, what the size of her pelvis is, the amount of water, etc.
The desire of the expectant mother to eat sweets should not be associated with the fact that a girl should be expected, just as when eating meat and cucumbers it is not at all necessary that the woman is expecting a boy.
Another sign says that moodiness and tearfulness during pregnancy are a sign of expecting a daughter, and calmness and drowsiness are a sign of a boy. Any changes in mood during the period of bearing a baby are not associated with the gender of the baby, but with current hormonal changes in the female body. Hormones also affect how a woman looks. It is progesterone, and not the gender of the child, that gives a woman attractiveness and femininity while expecting a baby.
