Each expectant mother It is very interesting to know the sex of your baby from the very beginning of pregnancy. That is why there are many ways that allow you to determine the boy or girl will be born even before it becomes clear from the results of the ultrasound. Often, even doctors can guess the sex of a baby from the characteristics of its heartbeat.
The heart of the fetus begins to beat after the first month of pregnancy. It becomes possible to listen to it by about 6 weeks of bearing a baby, this is the norm. But these data are relative, for someone the rhythm is heard a week earlier, and for the other, on the contrary. Surprisingly, the fetal heart begins to work at full capacity even when other organs and limbs are still in their infancy, you can see this on ultrasound.
Officially, scientists deny the possibility of determining the sex of an unborn child by heart rate. Similar studies are being conducted around the world that confirm this method, but its reliability is still 60% -70%. You can determine gender by heart rate, but a very important factor is the week of pregnancy. With the course of this position, the rate of heart beats in a baby per minute changes significantly, which can affect the results. Ultrasound gives an accurate result only after the 20th week of pregnancy, rarely the sex of the child is announced at 12-14 weeks, but such results may not be entirely accurate.
Heart rate depending on the gestational age
At the very beginning of pregnancy, the heart of the embryo beats at a frequency of 80 to 100 ulars per minute. Gradually, these indicators increase, so by 10 weeks of gestation, the indicators can increase to 160-180 beats. This is considered normal with good test results, indications of other studies and the excellent well-being of the woman herself. The rhythm is vital important body in a fetus up to 12-14 weeks of gestation, it can change and this is also considered normal. At first, it increases significantly, but after 10 weeks it begins to gradually decrease. So by 12 weeks, contractions range from 140 to 160 beats per minute, these values \u200b\u200bare stored until the onset of labor.
Changes in the frequency of strokes of the main organ of the embryo may indicate any problems in its development. Most often, the cause is a lack of oxygen, in which case the expectant mother is prescribed special diet, body positions for sleep and rest are recommended, as well as walks in the fresh air for at least 2-3 hours daily.
With any deviations, it is important to immediately pay attention to them, since such data may indicate the development of pathology. If the fetal heartbeat disappears completely, this indicates a stop in the development and death of the embryo. Sometimes the fetal heartbeat is not heard for other reasons, for an accurate diagnosis, ultrasound is usually performed immediately.
In any case, the decision on further actions and prescriptions is made by the specialist. Usually, even with minor deviations, additional studies are prescribed to rule out problems with the development of the baby.
Often during the examination, muffled tones are heard. You should not be afraid of this right away, the reasons can be completely harmless:
- attachment children's place to the anterior wall of the uterus;
- a woman is overweight;
- polyhydramnios.
Control over the fetal heartbeat allows not only to find out the sex of the unborn child, but also to remain calm for the mother, always knowing that the baby is doing well.
Sex determination by heartbeat
Doctors at each examination regularly check how the baby's heart beats. This is usually done with a special tube or phonendoscope. The doctor applies the instrument to the woman's abdomen and carefully listens to the rhythm. This procedure is planned, as the doctor needs to constantly evaluate the fetal heartbeat and pay attention to any abnormalities. As noted, there are differences in how the heart of a boy and a girl beats; differences can be found by several criteria.
These methods for determining the sex of a baby are not recognized by official medicine, but are quite popular and well-known. Not everyone takes them seriously, now most women trust only the results of ultrasound. But thanks to the usual devices for doctors, even the heartbeat of the embryo is heard very clearly, which allows you to evaluate it according to various characteristics. But when trying to determine the sex of the unborn child in this way, it is worth remembering that the fetal heartbeat depends on various factors, for example:
- the period of wakefulness and sleep of the baby in the womb, when he sleeps, the heart beats calmer;
- to what degree of formation is the muscle of the main organ of the embryo;
- gestational age, the rhythm becomes constant only by 20-22 weeks of pregnancy;
- the state of health of a woman carrying a baby, some diseases of the expectant mother cause oxygen starvation in the fetus, which leads to a slow heartbeat;
- the position of the woman's body during the fixation of the rhythm;
- the psycho-emotional state of a woman greatly affects the state of the fetus.
It is always worth remembering that these methods of determining whether a boy or a girl will be born in a few months do not have complete reliability. Often the results are true, but they can depend on many factors. Even ultrasound does not provide complete reliability of determining the sex of the baby.
Other ways to find out a boy or girl will be born
Methods for determining the sex of a baby can now be divided into two types: modern and past generations. But despite this, all of them are successfully practiced now. In most cases, women use folk methods for interest, in order to further compare them with the results of a planned ultrasound.
Our ancestors successfully established the sex of an unborn child without ultrasound and other studies. Various methods were used to find out whether a boy or a girl should be born.
With such methods, every pregnant woman can determine the sex of her baby herself. But it is worth remembering that the most informative is ultrasound, which can often give a 100% probability, especially if the child has taken the most favorable position for the study.
The numbers characterizing the fetal heartbeat are an informative indicator of the child's health status. The heart of an embryo, which is 4 weeks old from the moment of conception, is a hollow tube. During the first 6-12 weeks, the indicators of the fetal heart change greatly - the organ is actively developing and improving.
Norms of fetal heart rate depending on the duration of pregnancy
At the 5th week of pregnancy, the small heart is already beginning to contract. It is at this time that you can already listen to the heartbeat. Data on normal indicators contains a table:
| Week of gestation | Heart rate rate, beats per minute / average |
| Fifth (beginning) | 80-85 |
| Fifth | 85-105 |
| sixth | 102-126 |
| seventh | 126-149 |
| eighth | 149-172/161 |
| ninth | 155-195/175 |
| Tenth | 161-179/170 |
| Eleventh | 153-177/165 |
| twelfth | 150-174/162 |
| thirteenth | 147-171/159 |
| fourteenth | 146-168/157 |
| 15 to 40 | 140-160/150 |
By themselves, the numbers and norms are not the final indicators that the pregnancy is developing as expected. They should be evaluated together with the results of other analyses.
Methods for diagnosing a heartbeat in an unborn child
Valid methods include:
- ultrasound diagnostics;
- echocardiography;
- fetal doppler study;
- auscultation;
- cardiotocography.
Using an ultrasound procedure, the baby's heart rate can be measured at the 4th week of pregnancy and beyond. Diagnostics that is safe for the embryo and mother works quite reliably.
It is prescribed during routine screenings, with suspicion of deviations from the norms and in other cases. The shorter the gestational age, the more often the transvaginal research method is used.
Echocardiography is a type of ultrasound for listening to tones and rhythm using three scanners. She is informative on early dates, sometimes prescribed by a doctor in the later stages of pregnancy.
Doppler is used to assess the parameters of blood flow in the placenta, uterus, organs of the child and determine the heart rate. It is also, like ECHO-KG, a subspecies of ultrasonic measurements. Both studies can be carried out on the same instrument. At home, the expectant mother can use a mini-doppler, a compact portable device. To measure the heartbeat, the woman turns on the sensors, applies a special gel to the abdomen and, slowly moving the doppler, listens to the baby's heart rhythms. This procedure is informative in the second and third trimesters.
Auscultation is the most accessible and uncomplicated method for determining the child's heartbeat and extraneous noise using an obstetric stethoscope. Listening is carried out by placing the tube to the mother's abdomen in the region of the anterior wall of the uterus. Conducted by a gynecologist. The method is effective from the middle of the II trimester.
Performing an ultrasound procedure Cardiotocography (CTG) is informative in the second or third trimesters (from 18 weeks) and during childbirth. The rhythm of the baby's heartbeat is heard by a device akin to ultrasound through sensors in the form of a belt, which is attached to the circumference of the mother's abdomen. A graph of heart rate changes is recorded by a special monitor, then it is printed on paper. The specialist evaluates the indicators.
How to find out gender by heartbeat?
Future parents tend to look for simple ways to "guess" gender. Methods that take as a basis the characteristics of the fetal heart rhythms are referred to as the so-called folk, or near-medical, if the study does not use ultrasound, doppler or auscultation. Controversial moments, there are many assumptions in such measurements.
beats per minute
It is believed that the heart of girls is able to beat faster than that of boys. It turns out that if the number of heartbeats is 150 beats (in some sources - from 140 to 160) or a little more, then the mother is expecting a girl. 120-140 strokes counted - there will be a boy.
In addition to disputes about heart rate figures, some followers of this method claim that it is true at gestational ages from 12 to 20 weeks. Others claim that future parents can successfully determine the sex during the entire waiting period.
However, this approach is debatable. Regardless of the sex of the child, the indicators of the baby's heart rate in the absence of any anomalies, failures in the mother's body, should be normal. If there is a deviation both towards reduction and increase in the rhythm, attention should be paid to the general condition of the pregnant woman and additional studies should be carried out. Only a doctor can prescribe them.
Features of the heart rhythm in girls and boys
Future parents sometimes use the method of determining the sex of the heir by the nature of his heartbeats. The difference is based on the rhythm of the heartbeat. For boys it:
- measured;
- clear;
- smooth;
- uniform;
- monotone;
- loud;
- clean;
- matching the rhythm of the mother.
For girls:
- chaotic;
- uneven;
- muted;
- discordant with the rhythm of the pregnant woman.
You can use this method only as an additional one. Ignoring the fact that the baby's heartbeat tones have changed can be dangerous. For example, dull tones are a possible sign of polyhydramnios, anterior placenta previa.
Location of the fetus
It is believed that the boy's heartbeat is heard on the left, the girls - on the right. The method of listening to the child's pulse is not tied to a specific period.
This statement does not find support among doctors. In addition, it is contradictory - someone claims that the heart of girls is heard on the left, and on the right, on the contrary, boys.
How accurate are sex determination methods?
The probability that the "folk" methods are true is 50%, i.e. Either the prediction comes true or it doesn't. In fact, fetal heart rate depends on many conditions:
- gestational age;
- indicators of the work of the fetal heart (including deviations);
- hypoxia (makes tone deaf);
- the position of the pregnant woman during examination and listening to rhythms;
- wakefulness of the baby or his stay in a dream;
- mother's well-being.
It is difficult to determine the sex of a child by heartbeat with any certainty, using both the indicators of the tables and listening to it in non-medical ways, and the conclusion may be completely unreliable (we recommend reading:). An ultrasound examination by an experienced gynecologist is a reliable diagnostic method with a success rate of up to 97%.
The news of a conception that has taken place is always exciting. In all women, it causes a variety of emotions and experiences, but none of us perceives the situation in cold blood and unshakable. Even if the pregnancy was planned and you did not doubt it at all, the moment of confirmation of conjectures and conjectures awakens certain feelings in us.
But over time, the excitement subsides, the newly-made pregnant woman gets used to the new status and is now looking forward to the following news: who lives in the tummy?
Modern ultrasound diagnostics with a high degree of probability can determine the sex of the unborn child. But not before the due date. But we can’t wait, and even the future dad began to worry: who is there?
What if the bugger doesn't show itself? So guess later until the next ultrasound, and even before the birth itself.
There is a lot of debate about whether it is worth determining the sex of the child in advance. And if you are one of those who do not want to be aware of this, it is enough just to warn the uzista not to spread.
But many more parents cannot wait to find out the next most important and interesting news: the sex of the heir. And here the ancient methods of determining the sex of a child, which our ancestors used, can come to the rescue. Among these, you have probably heard about the method of determining sex by heartbeat.
How to determine the sex of a child by heartbeat?
There are several options for both the method itself and its interpretation. The first is the number of beats per minute. Everything here is so confusing that it is simply impossible to figure it out. The method is not official, it is not described in books on medicine, but, despite this, many obstetricians use it. Surely your girlfriends told you that their midwife accurately “calculated” the unborn child. Or just the opposite, which also happens. But how?
Some argue that the heart beats faster in boys, while others, on the contrary, assure that this is typical for girls. A variety of numbers are called: above 150 - girls, within 120 - boys, 160 or more - boys, below 140 - girls, and so on ...
In some variants, it is specified that the test is true only for up to 20 weeks or throughout the pregnancy. In general, the confusion is complete!
Another version regarding the differences in the heartbeat of children of different sexes is an unequal rhythm. They say that in boys the heart beats more rhythmically, measuredly: knock ... knock ... knock ... And the girls have a different “melody” - excited and chaotic: knock-knock-knock ... Although there is also information that the heart of boys knocks just faster and louder. And one more thing: the rhythm of the boy's heartbeat coincides with the mother's, but the girl's is different.
There is another way to determine the sex of a child by heartbeat - depending on the location of the heart, or rather, the fetus. Allegedly, girls and boys lie in the womb in different ways: if the baby’s heart is heard on your right side, expect a girl, on the left, a boy. Or maybe vice versa.
Is it true?
It all depends on whether the folk diagnosis coincided with the gender of the expected baby. Because in half of the cases, expectant mothers say that they did, the other half refute such tests with opposite results in reality.
Official medicine recognizes only one simple way to determine the sex of an unborn child -. And he has the right to be wrong. Only invasive diagnostics gives a 100% guarantee, when amniotic fluid or a piece of the placenta is taken for examination.
Regarding the heartbeat, doctors say that it depends on the gestational age, the state of the fetus at the moment (he is sleeping or awake), and even on the position of the mother's body in which she is being listened to. Undoubtedly, disturbances in the development of the heart can also affect the nature of its beating.
However, many gynecologists and obstetricians (especially older ones) do not miss the opportunity to express their guess based on the heartbeat heard. If you have such a preliminary verdict turns out to be true, you can think that it works.
In fact, such methods are nothing more than guesswork and the desire to know the secret inaccessible to humans, which came from the past. And for modern pregnant women, this is also a great way to have fun. So how do we arrange a test? Who are you expecting and what does the little heart say?
From the first weeks of pregnancy, future parents want to know who will be born to them, so they ask the gynecologist if it is possible to determine the sex of the child by heartbeat. And if some couples are driven by a simple interest, then for others this issue is really important.
Since ancient times, people have tried to establish, by various signs, the gender of the baby, which is in the mother's womb. They paid attention to the shape of the abdomen, the taste preferences of a pregnant woman, as well as to changes in her appearance. One of the ways is also considered to determine the sex of the child by the sound of his heart. How reliable is this technique? Let's try to figure it out.
Between attempts to find out the sex of the baby by outward signs in a pregnant woman and ultrasound, there is a way to determine the sex of the child by. Many, even experienced obstetricians and gynecologists, do not neglect this way of determining who a woman is waiting for: a boy or a girl.
When the male and female gametes merge, they form new life, which begins to grow and develop rapidly. Already on the 20-21st day, the heart is formed in the embryo, and some scientists call an earlier period - 14 days after the fertilization of the egg. However, at this stage it is impossible to hear its contractions.
With the help of ultrasonic sensors, the heart pulsation is first determined at a period of 6-8 weeks, and it is possible to clearly hear the heart beat through the stomach with a stethoscope starting from the 20th week of pregnancy. In the same period, the woman begins to feel the first movements of the fetus.
The reproductive organs are formed in utero, but up to 8 weeks they look exactly the same in female and male fetuses. After a short period of time, the gender characteristics that distinguish boys and girls will already be quite clearly defined.
The contraction of the heart muscle of the unborn child is an important indicator that determines its full development and the normal course of pregnancy, as well as giving an answer to the question of who will be born to a woman.
Methods for determining the sex of a child by heartbeat
Determination of the sex of the unborn child by heartbeat is carried out on the basis of various cardiological indicators, which have slight differences in the male and female fetus:
- Heart rate - a value that shows how often the work of the heart muscle occurs per minute. In boys, the heart rate is 120-140 beats, the heart of girls beats more rapidly, so this indicator fluctuates between 140-160 beats. Various conflicting opinions are expressed regarding this point: some doctors speak of the reliability of sex determination only for a period not exceeding twenty weeks, others prove the possibility of such a test at any period of pregnancy.
- Heartbeat . Reflects the sequence of atrial and ventricular systoles and diastole. In future men, the heart beats more evenly, smoothly and rhythmically. Girls are characterized by a chaotic, agitated rhythm. In addition, in the female fetus, the heart muscle works a little quieter.
- Topography of the heart . You can try to determine the sex of the child by the heartbeat by listening to the heart beat through the abdominal wall. If contractions are on the right side of the pregnant woman's abdomen, then a girl will be born, if on the left - a boy.
- Connection with maternal pulse . The heart of the male fetus contracts more loudly, clearly and simultaneously with the pulsation in the mother, in girls such a relationship was not revealed.
Method Reliability
Is it really possible to accurately determine the sex of a child by the fetal heartbeat? Some couples claim that their assumptions about who will be born to them have been confirmed. Other parents failed to find out the answer to this question, and they refute the theory by the fact that they had children of the opposite gender to the expected results.
Doctors call this technique an ordinary entertainment that helps the future mother and father brighten up the waiting time for the moment when the sex of their baby becomes reliably known. The only accurate medical method for determining the gender of an unborn child is the study of amniotic waters. However, it is performed only according to indications and not in order to find out whether a boy will be born or a girl, because in some situations amniocentesis carries.
The relationship between the fetal heart rate and the sex of the child
Although there are today modern methods, which with high accuracy determine the sex of a child in the womb, the method of determining sex by heartbeat has its supporters and is still used.
Since ancient times, doctors have used this simple technique, which does not require expensive equipment or complex studies. Experienced obstetricians today can absolutely determine the sex of a child by heartbeat, having in their hands only a simple wooden tube in the form of a wide funnel, called a stethoscope.
With it, the first heartbeats of the fetus can be heard for a period of 18-20 weeks. Auscultation (listening) of the child's heartbeats is performed in a pregnant woman through the abdominal wall of the abdomen. The work of the heart is heard as distinct double rhythmic beats. The doctor examining the fetal heartbeat determines such characteristics as: the frequency of beats per minute, rhythm, the nature of the tones, the point of the best auscultation of the heart.
All characteristics of heartbeats give an idea of the vital activity and condition of a developing child. But, not only that. Doctors have long established that there is a definite difference between the fetal heartbeats of a boy or a girl. There are several ways to determine gender by fetal heartbeat.
Methods for determining sex by fetal heartbeat
- The frequency of beats per minute. This criterion has an ambiguous interpretation. But, many experts are inclined to believe that the boy's heart makes fewer contractions per minute than the girl's heart. If the number of heart beats is equal to or less than 140, then it is worth. If, when listening, there are more than 140 heartbeats, then a girl will be born. This test is considered more reliable at gestational age, no more than 20 weeks. Although it is believed that it can be used throughout pregnancy;
- The rhythm of the heart also differs in boys and girls. The boy's heart, as it turned out, beats more rhythmically, measuredly and clearly. In addition, as established by observations, the heart rhythm of the boy coincides with the rhythm of the mother's heart. The girl's heartbeat rhythm is less ordered, there is no clear beat, there are accelerations and decelerations in the work of the heart muscle;
- The sex of the child by heartbeat can be determined depending on the location of the fetus, and, accordingly, on the sounds emanating from the heart. You can determine a boy or girl by heartbeat by a more pronounced sound coming from the right or left side of the abdomen. If the heart sound is more pronounced on the left, then it is worth waiting for the appearance of a boy. If the heart sounds are more audible on the right, then a girl will be born;
- Tone of the heart. It is determined by experienced obstetricians. In boys, heart tones are clearer, in girls, they are muffled.
Reliability of determining the sex of a child by heartbeat
The time-tested method of determining the sex of a child by heartbeat is questioned and criticized by both official medicine and women who tested this method with a negative result. Medical science claims that the characteristics of the heart of a child in the womb depend on many factors:
- Pregnancy period. On the different stages During pregnancy, the baby's heart works in different modes. For example, in the first weeks, the heart of a child (both a boy and a girl) beats slowly, rhythmically, calmly. The number of beats per minute is not more than 100. Starting from the 18th week, the number of heartbeats in boys increases to 150 per minute, in girls - up to 140 per minute. Changes in heart rate in accordance with the gestational age are explained by the development of vegetative NS of the fetus;
- Activity of the child (sleeping or awake);
- Features of the development of the child's heart;
- The physical and emotional state of the mother, her posture while listening to the fetal heart;
- Muscular tone of the uterus;
- Location of the child in the uterine cavity.
Modern medicine does not recognize the old method of determining sex by heartbeat. High-tech diagnostic tests help to see the fetal heartbeat and the sex of the child. It is carried out after 12 weeks of pregnancy. Sometimes this method fails and makes mistakes (in 97% of cases - the exact result).
One hundred percent guarantee of determining the sex of the fetus can be obtained with invasive diagnostics, which is carried out according to certain indications. So what - trust or not the results of the fetal heartbeat test, boy or girl? The advice of doctors to pregnant women regarding this test is not to accept its result as final.
It is possible to test this method on yourself, compare it with the results of other studies. In the end, it is not so important for parents to find out the sex of the child by heartbeat, or in other ways. His mothers are also important.
