Do you want to have a son? Or do you only agree on a girl? Then try to program the gender of the unborn child. It turns out that this can be done without super-sophisticated medical technologies.
The sex of the child is determined at the time of conception, - says Ph.D., an employee of the Department of Obstetrics and Gynecology of the St. Petersburg Medical Academy. Mechnikova Elena Ostrovskaya. - A spermatozoon carries either X (female) or Y (male) chromosomes. If the egg is fertilized by a "female" sperm, then a girl will be conceived. If he reaches the “male” target first, a boy will be born. The art of planning the sex of a child is precisely to help “ours” and block the path of carriers of the “wrong sex”.
Doctors are the best at this task. Using laser technology, they can separate the spermatozoa into "boys" and "girls". The success rate in this case is quite high - 91%. But this method is used only for in vitro fertilization.
You can give birth to a child of the desired gender on your own, - says Elena Ostrovskaya. - You just need to know some features of the fertilization process.
It is known that male spermatozoa are small and mobile, but they are less tenacious than slow female ones. Therefore, during sexual intercourse that occurred 2-3 days before the moment of maturation and release of the egg, girls are usually born. Romantic meetings on the day of ovulation end with the birth of a boy.
An error in determining the ovulation period, even for one day, can lead to the opposite result - a boy will be born instead of a girl.
Tell me what you eat...
Scientists have found that the sex of the unborn child is affected by the mother's diet before conception, continues Elena Ostrovskaya. - Depending on what a woman eats, her internal environment can be alkaline (favorable for the promotion of "boys") or acidic, in which "girls" survive well.
Future mothers who dream of a boy should lean on foods containing potassium and sodium (see table). And for those who want a girl, you need to give preference to foods rich in calcium and magnesium.
This diet has been tested on the basis of the Department of Obstetrics and Gynecology of the Academy. Mechnikov and showed excellent results. 80% of expectant mothers who ate right gave birth to a child of the right gender.
Don't get lost in the rhythm
Studying the data on the influence of various factors on the sex of the unborn child, - says Elena Ostrovskaya, - we found strictly defined combinations of biorhythms of a husband and wife, at which a boy or girl is conceived. If the wife's biorhythms are stronger, a girl is born; if the husband's, a boy is born.
Knowing the dates of birth and some features of the reproductive life of a woman - the dates of childbirth, abortion, etc., it is possible to compose the biorhythms of a husband and wife. And according to the combinations of biorhythms - an "individual plan" for conceiving a son or daughter.
By studying combinations of biorhythms, it is possible to identify the causes of inexplicable infertility of married couples, - Elena Ostrovskaya believes. - Childless couples usually have absolutely identical biorhythms, while in couples with children, one of the spouses periodically dominates.
And yet, an absolutely reliable method that allows you to program the sex of a child does not exist today. Even with the most accurate calculations, errors are possible.
Myths about planning
1. Blood renewal method. It is believed that the blood in the body of a woman is renewed every three years, in the body of a man - every four. The age of future parents is divided by 3 for women and 4 for men, respectively. Whose remainder is greater - a child of this gender will succeed. The method has been repeatedly tested by doctors. According to them, its reliability does not exceed 60%.
2. The intensity of sexual relations. It is believed that the more often there is sexual intimacy, the more likely it is to give birth to a boy. With frequent meetings, spermatozoa do not have time to mature. The optimal rhythm for conception is every other day.
Another opinion
Tatyana Zolotukhina, Doctor of Biological Sciences, Head of the Laboratory of the Medical Genetic Research Center of the Russian Academy of Medical Sciences, says:
It is impossible to accurately plan the floor. When using diets, failures are inevitable. As for biorhythms, this is a new method, which does not have a serious research and evidence base.

Everyone knows that nature "chooses" the sex of the unborn baby. But there are always people who want to make this choice themselves. They have at their disposal a lot of “tested” methods that allegedly allow them to conceive a boy or a girl. What are these methods based on and do they guarantee success?
A bit of physiology
In each cell of the human body there are 23 pairs of chromosomes - 22 pairs of autosomes (non-sex) and 1 pair of sex chromosomes. Each pair of autosomes in men and women is identical. Only the sex chromosomes differ: a woman has two X chromosomes, a man has one X chromosome and one Y chromosome.
In any woman, all eggs contain one X chromosome (there are simply no other sex chromosomes in the female body). Male spermatozoa are of two types: with the X chromosome and with the Y chromosome. If the egg is fertilized by X-spermatozoon, a girl will be born, if Y - a boy. Thus, the sex of the future baby depends only on the man! A woman can "do her bit" only in the form of the X chromosome, and the responsibility for the second necessary part lies with the pope.
I believe - I do not believe
Whether to believe signs is a personal matter for each couple. Of course, most of the signs regarding the sex of the unborn baby are based on superstitions and prejudices. Some of them are based on nothing at all. Judge for yourself.
According to Chinese tradition, in order for a boy to be born, a woman needs to lie with her head to the north during intercourse, and to conceive a girl - to the south. Among the Germanic peoples there is a sign that if the conception is "guessed" under the rain, a girl will be born, and if under sunny weather - a boy.
An interesting sign of the ancient Slavs (it can easily bring discord in the relationship of spouses): if a woman loves a man more than he loves her, a girl will be born, and if vice versa, then a boy.
There is also such a sign: if conception occurs in the fall, then boys are more often born, and if in the spring - girls. This method is based on the "vitaminization" of the mother's body - they say, in the fall there are a lot of vitamins in the body, and the boys "tie up" in more comfortable conditions! And the girls agree to be born in the conditions of spring hypovitaminosis. Nevertheless, according to science, the saturation of the female body with vitamins in no way affects the likelihood of fertilization with X- or Y-sperm. Of course, vitamins are necessary for the normal functioning of the body, especially when planning a pregnancy. But so far, not a single vitamin has managed to take on the role of "determinant" of the sex of the unborn child.
Temperature technique
This floor planning technique is very common because it is quite simple to apply. Its essence lies in the fact that Y-spermatozoa quickly die under the influence of high temperature, while carriers of the X-chromosome are more resistant to heat and cold. It is impossible for dads who want to have an heir to overheat! They will have to forget about tight jeans, tight underwear, a sauna, a bath, a long stay behind the wheel. To work in blast furnace shops - no, to a cold soul - yes!
There is some truth in this, but these precautions are more about the possibility of having children in general, and not specifically a boy or a girl. The fact is that under the influence of high temperature, denaturation of sperm protein occurs and all spermatozoa lose their activity. Y-carriers die a little earlier, X-carriers - a little later, and it is impossible to calculate the segment when the majority of those or others will remain "alive".
Dinner is served!
The method of planning the sex of a child using a special diet is a special topic. What kind of diets are not offered to future parents - and electrolyte, and French, and Slavic, and Japanese ...
The goal of all these diets is the same - to saturate the mother's body with certain electrolytes (these are important biological substances involved in almost all spheres of the body's life). All of them are equally necessary for the body, however, spermatozoa have their own "preferences" in saturation with specific elements. Carriers of the X chromosome survive better in an environment saturated with calcium and magnesium, and Y - with sodium and potassium. And these substances are found in certain foods.
This is what the girl’s “food set” looks like: eggs, fresh fish, eggplant, beets, carrots, cucumbers, peas, capsicum, onions, green salad, unsalted nuts, dairy products, herbs, honey, jam. From drinks - coffee, cocoa, hot chocolate.
The boys "got" meat, bread, rice, potatoes, mushrooms, lentils, cherries, bananas, apricots, oranges, peaches, dates, dried fruits and traditionally male drinks - beer, wine, fruit juices.
This fairly common method of sex planning deservedly causes a particularly wary attitude among doctors, because, unlike other methods (calculating the ovulation period, the frequency of sexual contacts, choosing certain positions, etc.), the diet directly affects the state of the mother's body. An unbalanced diet (and any diet, in fact, is just that) threatens with an exacerbation of chronic diseases, a decrease in immunity, a state of hypovitaminosis, and at the same time does not at all contribute to the birth of a child of the desired sex.
"Call of blood"
One of the most popular methods for determining the sex of an unborn child is the calculation of the “renewal” of blood. According to this technique, the state of the blood changes in a certain cyclic mode: at the beginning of the cycle, the blood is “fresh and stronger”. This determines the sex of the unborn child - whose blood is “younger”, that parent determines the sex of the unborn child.
Simple in its essence to apply the method is based on numerological theory. The technique of numerical regularities has come down to us from ancient times; according to this theory, it is believed that all living organisms develop cyclically. At certain intervals, a programmed restructuring of the body occurs, including the “renewal” of the blood. For women, this interval is three years, for men - four.
The calculation is simple: the age of future parents is divided, respectively, by three for women and four for men. Whose remainder is greater - that floor will turn out. And the correction: if the mother is a carrier of a negative Rh factor, then the result will be exactly the opposite.
Of course, there are no laboratory tests to capture and evaluate the "freshness" of the blood. There is also no scientifically confirmed regularity in the birth of children of a certain gender using this method. However, it is impossible not to note the objective value of this method - it is completely harmless to the body!
Sprinters and Marathon Runners
However, no matter how skeptical we are, there are a number of observations that are statistically confirmed. These include the calculation of the time of sexual intercourse relative to ovulation. Ovulation is the release of a mature egg from the ovary as a result of the rupture of the follicle - the vesicle in which the egg was located. Further, the egg enters the lumen of the fallopian tube, where the fertilization process takes place - its fusion with the sperm.
Spermatozoa differ in their properties. Spermatozoa carrying the male Y chromosome are more mobile than those carrying the X chromosome, and therefore they are able to reach the egg first. So Y-sperms seem to have an advantage. But, getting into the acidic environment of the vagina, Y-spermatozoa become unstable and quickly die, opening the way for their slow X-brothers. It turns out that spermatozoa with the X chromosome are more viable due to the structural features of the membrane and can “sit” in the fallopian tube in anticipation of ovulation for up to 3 days. Spermatozoa with a Y-chromosome are incapable of waiting at all.
However, the closer the day of ovulation, the more alkaline the vaginal discharge becomes, and the more likely the Y-sperm to survive. On the basis of this, theories have arisen stating that during sexual intercourse that occurs 1-3 days before ovulation, less durable Y-sperms die and the egg is more likely to be fertilized by an X-sperm, that is, a girl will be born.
And if sexual contact immediately precedes ovulation or occurs immediately after it, then most likely a boy will be born, since the more mobile and faster Y-spermatozoa will “run” faster to the released egg.
The condition for this calculation is the exact determination of the date of ovulation. There are several ways to do this: simple tests to determine ovulation, examination of cervical mucus, measurement of basal temperature, and the most reliable - folliculometry.
Method measurements basal body temperature is the most affordable, simple and fairly reliable. The principle of its operation is to build a temperature curve. To do this, every morning, without getting out of bed, measure the rectal temperature and mark it by drawing a kind of graph. You should start from the first day of the cycle, which corresponds to the first day of menstruation. Around the middle of the cycle, a flat temperature line suddenly drops sharply - this is the day of ovulation. The next day, the line goes up just as sharply - this corresponds to the beginning of the second (luteal) phase of the menstrual cycle.
Method cervical mucus studies It is based on the fact that on the day of ovulation, mucus is maximally saturated with estrogens and becomes plentiful, extensible, viscous. When dried on glass, the mucus crystallizes, and bizarre patterns can be seen under a microscope - a “fern symptom”. Similar changes occur with saliva. In the pharmacy, you can buy a small device to determine the approximate date of ovulation, on which you can apply saliva and observe the appearance of the "fern". It should be borne in mind that the fern effect appears not only on the day of ovulation, but also in the days closest to this date.
However, in modern life, the most common way to determine the day of ovulation is folliculometry- Monitoring the maturation of the follicle using ultrasound. At the same time, the process of maturation of the follicle is monitored by day, and the reliability of ovulation is confirmed by the presence of a corpus luteum - a formation that appears at the site of a burst follicle.
The result is guaranteed!
So are there really no reliable ways to give birth to a girl or a boy? There is. Science does not stand still, and in medicine, high technologies are periodically introduced into general clinical practice. One of these breakthrough discoveries is pre-implantation genetic diagnosis of the fetus (PGD). This technique began to be used in 1990. Now it is carried out as part of the IVF program - in vitro fertilization. This is an assisted reproductive technology method in which conception occurs outside the mother's body. The egg is fertilized by the sperm “in vitro”, i.e. under laboratory conditions, and then transferred to the uterus.
PGD allows you to determine the sex and conduct genetic testing of the embryo even before transferring it to the uterine cavity and, accordingly, even before pregnancy. The "candidates" for this study are couples with a high risk of transmission of a hereditary disease.
But, despite the fact that this technique is widely used, today it does not meet the requirements of couples ordering a certain sex of the child, since it is used only to prevent the birth of children with diseases linked to sex. This extremely complex and expensive procedure is designed to genetically control the fetus, and sex determination is only a “side effect” of this manipulation. Even the latest high reproductive technologies do not give a 100% guarantee of results, and sometimes this procedure can cause complications. Therefore, pre-implantation diagnostics of the fetus is carried out only when necessary and is not intended to satisfy idle curiosity or whims.
Perhaps the sex of the unborn child is one of the most common topics discussed during pregnancy. From ancient times to the present day, couples have been actively looking for a way to make an “order for a stork”. The desire to have a child of a certain gender is quite natural, unless it acquires obsessive traits and develops into a negative attitude towards a child of an “unwanted” gender. To date, there is not a single reliable scientifically based way of conceiving a fetus of a certain gender. And is it needed? After all, the consequences can be catastrophic for all mankind. The question of the gender of the future baby is very complex - and at the same time simple. As it should - so it will be. The birth of a child, the arrival of a new person into the world is a True Miracle, and we must treat it with respect and awe. You just need to direct your efforts to planning pregnancy in order to have a healthy and happy child. Boy or girl - does it really matter?
Its reliability can be checked simply: substitute the values for already born children.
Calculate the gender of the unborn child long before his birth- rare "future moms and dads" will refuse such an opportunity. Judging by the description, the ancient Chinese secret table, which has lain in the catacombs for 700 years, can help with this. Using the table is very simple, but the most interesting thing is that its reliability can be checked without waiting for the birth of the child - you can simply substitute the values \u200b\u200bfor already born children and make sure that the table gives the correct answer every time.
Horizontally, you need to find the month when the child was (will be) conceived (track from the month of birth 9 cells back, if you are only checking the validity of the table for now). On the vertical - the age of the mother when she will give birth to this child. At the crosshairs, M means boy, F means girl. Don't confuse!!! Vertically, the age of the mother is not at the moment of conception - but when she will have to give birth (the number of full years).
The secret is that such tables are usually distributed with this error - it is indicated everywhere that the mother's age at the time of conception should be taken vertically - however, the literal translation of the table description indicates exactly that the mother's age is taken vertically during the alleged birth.
For example: if a woman's month of birth is February 1980 and she is 23 years old, and she conceived a child in March 2003, then she will give birth to him in December 2003 and she will still be 23 years old at the time of the birth of the child and will definitely be a boy. But if a woman's month of birth, for example, is July 1980, and she conceived a child in November 2003, then at the time of conception she was a full 23 years old. In other publications, they assure that the age of the mother at the time of conception is taken vertically. But if we take the age of the mother at the time of conception, then according to this table, she should have a boy, although, in fact, when she gives birth in August 2004, she will be a full 24 years old and, according to this table, she will have will actually be a girl. It is this nuance that you can check on your own - by taking and calculating from this table who has already been born to your friends, relatives, etc.
AND USEFUL TIPS
How to "program" the gender of the unborn child
For the conception of a boy, the predominance of potassium and sodium ions in the diet, and as little as possible calcium and magnesium ions, is recommended. To do this, it is proposed to eat meat, fish, potatoes, mushrooms, dry white beans, lentils, dried peas, legumes, eat only protein from eggs. From fruits, cherries, apricots, peaches, prunes, dried apricots, and dates are especially needed. Recommended drinks: tea, beer, fruit juices, soda mineral waters. Also, for a woman who wants to conceive a boy, cookies, biscuits, semolina and rice are useful. In addition, a woman is advised to salt all food as much as possible, eat canned foods and yeast.
Not recommended: milk and dairy products, calcium mineral waters, shrimp, crabs, fish roe, egg-based pastries, bread, pancakes, waffles, milk confectionery, green salad, green beans, green beans, raw cabbage, watercress lettuce, dill, walnuts, hazelnuts, almonds, peanuts, cocoa, milk chocolate.
To "program" a girl
In order to conceive a girl, the diet of the expectant mother should be rich in calcium and magnesium ions, but low in potassium and sodium. This combination is provided by: meat in limited quantities, fresh or frozen fish, all types of baked goods without salt and yeast, eggs, potatoes in limited quantities, eggplant, asparagus, beets, carrots, cucumbers, watercress, green beans, peas, peppers, onions, tomatoes. As well as unsalted almonds, hazelnuts, peanuts, sugar, honey, spices, jams and fragrant herbs.
From drinks are useful coffee, tea, cocoa, calcium mineral waters. At the same time, salted foods, carbonated drinks, canned juices, and Pepsi-Cola should be avoided.
Necessary exclude sausages, ham, smoked meats, salted and canned fish, crayfish and shrimp, all cheeses, ice cream, ordinary breads and industrial confectionery, corn and canned vegetables, fried potatoes, raw tomatoes, lentils, salted dried fruits, plums, apricots, cherries , bananas, oranges, currants, melons. During this period, you should not eat salt, yeast, soda, olives, margarine, spicy sauces, and any canned food. The diet should be followed from the beginning of the menstrual cycle until the intended conception.
The question "boy or girl?" interested humanity at all times. And if now it's just out of curiosity, then before it was practically a matter of life and death for a newborn, since it was preferable to give birth to boys. The girls could have had a very sad fate. Astrologers of antiquity argued that Monday and Friday, the days of Venus, would be optimal for the conception of a girl, and Thursday and Sunday for the conception of a boy, because they are in the power of Jupiter. In Ancient Russia, there was a rule: if you want a boy, put an ax under your pillow, and don’t forget ribbons for a girl.
They tried to predict the sex of the child already pregnant by the shape of the abdomen: a sharp and low abdomen indicates a boy, and a rounded high tummy indicated that a girl lives there. And the belief “a girl takes beauty from her mother” is still relevant. As well as fortune-telling on a wedding ring: if you hang the ring on a thread in front of your stomach and it goes back and forth, it’s for a girl, and if it writes out circles, it’s for a boy.
Modern parents, when calculating the sex of their unborn child, often resort to the following methods:
conception on a diet
This method is very popular, because the essence of it is that what you eat affects the sex of the child. If you want a boy, lean on "male" foods rich in animal protein: meat, eggs, fish, bakery products. Foods high in caffeine (especially green tea) and salt also help to conceive a boy - pickled cucumbers come in handy! Those who want to braid pigtails need to enrich their diet with dairy products, fish, you can eat sweets: honey, chocolate, jam, yeast-free pastries and, if possible, refuse to use salt or reduce it to a minimum.
By renewing the blood
This method was used in ancient China, as they believed that all organs and systems are updated like clockwork. Male blood is renewed every four years, female - once every three years. There is a chance that the child will have the sex of the parent whose blood was "fresh" at the time of conception. Calculating the age of the blood is easy: you need to divide the age of the future dad by three, and mom by four. However, if you have had blood transfusions, blood loss surgery, childbirth or abortion, the method may not be reliable. The countdown will have to start exactly from the age when this happened.
By ovulation
I personally consider the method of calculating the sex of the fetus by ovulation the most reliable and most scientific. Using this method, I calculated the gender of my daughter (they didn’t plan a daughter, it just so happened that I knew the date of her conception with a difference of plus or minus two days, and this helped to calculate the gender) and for the second time suggested that I might have a boy (there was intimacy at the height of ovulation ).
As you know, the sex of the child depends on the man, because spermatozoa carry XY chromosomes, and females only XX. Everything is explained by the peculiarities of the “female” spermatozoa: they are little sloths - they do not actively make their way to the egg, unlike the agile boys, but they have a higher survivability. If sexual intercourse occurs 3-4 days before the expected ovulation and abstinence on the day of ovulation, there is a high probability of conceiving a girl, because the mobile and agile spermatozoa with the Y chromosome are very sensitive to the vaginal environment and do not live long. If you are planning to become the parents of a boy, plan an intimate evening on the day of the expected ovulation - nimble male spermatozoa will quickly reach their goal!
Planning a baby's gender is a lottery, so get ready to love your miracle, whether it's a tiny girl or a precious boy!
The article will be useful to parents who want to ask the gender of the child.
It is quite natural to desire to have a child of one sex or another. However, the question: is it possible to program the sex of a child before birth is still relevant.
The sex of the child depends on the man. In fact, any egg cell carries only X chromosomes and never contains Y chromosomes. The male reproductive cell, on the contrary, contains different chromosomes: X and Y. When chromosomes divide during preparation for fertilization, one part of the spermatozoa will receive 22 ordinary chromosomes + one Y chromosome. Thus, spermatozoa are not the same: in addition to the 22 ordinary chromosomes, each of them has either an X chromosome or a Y chromosome. If the egg (22+X) is fertilized by a sperm containing the X chromosome (22+X), the embryo with the chromosome set will be 44+ XX; this means that a girl will be born. If the egg is fertilized by a sperm carrying a Y-chromosome, then a child will be born with a chromosome set of 44 + XY, that is, a boy.
That is why it is the sex chromosome of the fertilizing sperm that determines the sex of the child. If an egg were fertilized by the same egg (which is absolutely impossible), only girls would be born. Although there are families where only boys or only girls are born, about the same number of boys as girls are born every year, with a slight preponderance towards boys.
Immediately after the penetration of the sperm into the egg, the nuclei begin to converge. First, they increase in size, and from the chromatin serving as a kind of raw material, chromosomes are formed. The thin membrane surrounding the set of chromosomes bursts in both cells. Cell nuclei come close to each other and merge into one nucleus: this moment cannot be caught. As a result of the fusion of the nuclei, the egg turns into a human egg (embryo), with great potential and new genetic baggage.
In ancient times, it was believed that boys come from the left testicle, and girls - from the right. Therefore, in order to conceive the desired offspring, various acrobatic poses were recommended and even advised to sacrifice one testicle. According to popular beliefs, the sky and stars can predict the sex of the unborn child. In ancient times, for example, they believed that if the moon changes in the first 3 days after childbirth, then the next child will be of the opposite sex. They also tried to determine the sex of the child, based on the position of the moon in a certain sign of the zodiac at the time of fertilization. In ancient China they used - a coincidence or not, but it is quite accurate.
Other times, other methods. Now some believe that it is possible to determine the sex of a child based on how much time separated the moment of sexual intimacy and the moment of ovulation. Others offer a special diet for the birth of a child of a certain gender. But let's be clear from the outset: none of these methods are supported by hard scientific evidence.
First hypothesis: the moment of ovulation
It is known that spermatozoa containing the Y-chromosome move at a faster rate through the female genital tract than spermatozoa with the X-chromosome. Some conclude from this that when the moment of sexual intimacy coincides with ovulation, the first to reach the egg and fertilize its sperm with the Y chromosome, that is, a male embryo is formed. Conversely, if ovulation occurred 2 days after intercourse, sperm with a Y chromosome will arrive at the meeting point with the egg, in which case a girl will be born.
Second hypothesis: intensity of sexual relations
There is an opinion that the more often there is sexual intimacy, the more likely it is to give birth to a boy. This is allegedly facilitated by the intensity of orgasm in a woman, since uterine contractions accelerate the movement of spermatozoa carrying the Y chromosome. Finally, high acidity of the vaginal contents is favorable for X-chromosome spermatozoa, and low acidity for Y-chromosome spermatozoa. The best recipe for a boy to be born is the following: the moment of sexual contact should be as close as possible to ovulation, and immediately before it it is recommended to take a sitz bath and use douching to irrigate the vagina with warm water with sodium bicarbonate dissolved in it, that is, baking soda.
If you want a girl, do the opposite. Sexual intimacy is recommended 3-4 days before ovulation, relatively frequent intercourse in the previous days, the absence of an orgasm in a woman, vaginal douching with warm water with the addition of ordinary table vinegar! All these recommendations depress and deprive the charm of the love act. In addition, they are not backed by science. There is always one chance in two, because no matter what, nature creates as many boys as girls!
Third hypothesis: a special diet
It turned out that in some experimental animals there is a relationship between the acidity of the nutrient medium in which the gametes swim and the sex of the unborn child. It has been theoretically established that sodium to potassium favors the sperm carrying the Y-chromosome, while calcium and magnesium, on the contrary, stimulate the formation of a female fetus. A special diet for a person has been developed, with which you can plan the sex of the child. Adherents of this technique recommend that a woman strictly observe the prescribed diet for 3 months before conception. If you violate the ban once, all efforts will be in vain! This mode is very embarrassing. In addition, pregnancy does not always occur at the end of the period of special nutrition, and it may have to be extended. It should also be taken into account that such a diet is absolutely unbalanced and therefore categorically contraindicated for the expectant mother. Judge for yourself: milk, eggs, cheese, fresh fruit are not allowed if you want a boy! The effectiveness of the method is low, it often does not meet the expectations of married couples who decide to do this.
Fourth hypothesis: sperm selection
The most promising of the directions, representing the possibility of choosing the sex of a child even before conception, is the selection of spermatozoa. By creating a certain environment for their migration, it is possible to isolate fractions containing a chromosome break. But the effectiveness of this technique, widely publicized by the media, has not yet been proven. However, it is quite possible that soon we will learn how to use genetic probes, and the choice can be made accurately.
But we must not turn a blind eye to the aesthetic side of the question: is it permissible to use these techniques simply at the request of the parents, or is medical permission required? Scientists all over the world are pondering this question today.
