What week can you determine the sex of the child? Early sex of the child
Waiting for a child is a happy and exciting time for future parents. For nine long months they fantasize, represent their baby and dream of seeing him sooner. Every mom and dad would be interested to know which of them will look more like a crumb and, of course, what gender it will be. And if you find out whose baby has inherited the nose and eyes, it is unlikely that it will work out before he is born, then it will be easy for the modern doctors to determine whether the boy will be born or the girl.
Like other physical parameters, the sex of the child is laid directly at the moment of conception. After the merger, the egg cell and the sperm cell form a single cell containing 46 chromosomes with genetic information, 23 of which were received from the mother and exactly the same number from the father. Of these 23 pairs of chromosomes, only one determines the sex of the fetus.These crucial chromosomes are referred to as X and Y. Many people know from a school course in general biology that all eggs contain only the X chromosome, and the sperm, in turn, can contain not only the X but also the Y chromosome. It is on what chromosome the sperm brought to the egg, and the sex of the child depends.
Who lives in the tummy?
Despite the fact that when a woman finds out about pregnancy, a girl or boy is already growing and developing in her womb, the moment when the sex of the child can be determined does not occur immediately. The first 5 weeks of pregnancy, the genitals of the fetus develop on the female type, regardless of what sex the child was conceived. Therefore, it is impossible to determine at this time who will be born. And only on the 6th week, when the sex glands begin to form in the embryo, under the action of the H-Y antigen (the synthesis of which is controlled by the Y chromosome) in the male individual, the unspecific sex glands turn into testes. Subsequently, under the influence of hormones produced by the glands, multiple changes in the genital organs occur in the embryo. In boys, the penis begins to form, and in girls the labia and clitoris.By the beginning of the 16th week of pregnancy, the external organs of the reproductive system are considered to be formed, and parents can determinesex of the child by ultrasound.
For 40 weeks, the expectant mother must undergo an ultrasound examination three times: for a period of 10–12 weeks, 20–22 weeks, and 32–34 weeks. This is necessary in order to clarify the duration of pregnancy, check the condition of the fetus, the number of fetuses, eliminate developmental defects, and determine the position of the fetus in the body of the uterus. However, among other things, with the help of ultrasound, the doctor is likely to determine the sex of the fetus.
Examination by means of ultrasonic waves is absolutely painless and does not harm either the mother or the child. Many women are interested in which week you can determine the sex of the child using ultrasound. In recent years, a major breakthrough has occurred in the field of ultrasound diagnostics. Modern devices are able to show not just a blurry silhouette, vaguely reminiscent of a baby, but a clear 3D image. Due to this progress, the doctor can assume the floor of the crumbs already during the first scheduled examination.However, the shorter the gestation period, the more likely the error.
Ultrasound is currently one of the most accurate ways to determine gender. But the best time for it to get a reliable result is 16 or more weeks of pregnancy.
Mother's blood test
Since almost all parents strive to determine the sex of their future child, scientists continue to find new ways to uncover this mystery. One of these innovative techniques is the mother’s DNA analysis. This technique is clinically tested and consists in the study of the genetic composition of the blood of the expectant mother.
The fact is that during pregnancy a small number of fetal blood cells enter the woman’s circulatory system, which means that if the Y-chromosomes are found in the blood, it can be concluded that a boy will be born. For this analysis, it is necessary to donate a small amount of venous blood, which will not give the expectant mother any discomfort and will not lead to undesirable consequences.
The study can be carried out already from the 6th week of pregnancy, but for the most reliable results, it is better to wait until 9 weeks.Thanks to this method, women who, for one reason or another, are wary of ultrasound diagnostics, now have the opportunity not to “guess the coffee grounds” who will be born, but to determine the sex of the child without ultrasound.
In the overwhelming majority of cases, the desire of parents to find out the sex of the child in the early stages is connected with trivial curiosity. But sometimes sex determination is a necessity and is carried out for medical reasons. In nature, there are a number of dangerous genetic diseases that are transmitted mainly to only one sex. The best known example is hemophilia. In such cases, the birth of a child of a particular sex may be highly undesirable, and if pregnancy is preserved, physicians who take birth must be prepared for a possible critical situation.
Of course, under the circumstances, it is extremely important for parents to know which week the sex of the child can be determined. An ultrasound study does not give a 100% guarantee of an accurate determination of sex, even over a long period of pregnancy. In this regard, a reasonable question arises:How to determine the sex of an unborn child exactly and as early as possible?
There are a number of methods consisting in the surgical invasion of the uterine cavity for the collection of biological material. These include: chorionic biopsy, cordocentesis and amniocentesis. However, it is important to remember that these methods are extremely unsafe and can lead to the development of complications and also increase the risk of miscarriage, which is why they are never carried out without serious medical indications.
Amniocentesis is a procedure in which a sample of amniotic fluid is taken from a mother for examination. To do this, pierce the anterior abdominal wall and uterus with a syringe, and make about 15 ml of amniotic fluid. The whole procedure is controlled by ultrasound. Most often, amniocentesis is performed with local anesthesia, but in some cases, general anesthesia may be used. This analysis is carried out in the period from the 16th to the 18th week of pregnancy.
Chorionic biopsy is performed at an earlier date. This is the case when it is possible to determine the sex of a child with an accuracy of 100% already at 7-9 weeks of pregnancy. The technique consists in collecting from the body of the uterus with a special needle a small number of chorionic cells, that is, a portion of the outer shell of the embryo,to further determine the chromosomal composition of the fetus. There are two options for this procedure: vaginal, when the necessary material is taken through the cervix, and the abdominal - the material is taken by puncture the anterior wall of the abdominal cavity. As with the amniocentesis, biopsy sampling is performed strictly under ultrasound control.
Cordocentesis is a diagnostic method in which cord blood is tested. Such a study can also harm the fetus, so they use it only when there is a serious need.
Unscientific methods for calculating gender
Some prospective parents are interested in what week you can determine the sex of the child, without resorting to laboratory research methods and ultrasound. There are many theories with which you can try to calculate the sex of a baby from the moment of its conception. All of them are built on different assumptions and have practically no scientific substantiation, but, despite this, more than one century continue to exist.
So how to determine the sex of an unborn child with the help of such methods is quite simple, they have become very popular among pregnant women all over the world.However, the reliability of the results obtained in this way remains in doubt, and the cases of coincidence, in the opinion of most scientists, are merely accidental.
Theory of blood renewal
One of the unscientific methods of establishing sex is based on the theory that over time, blood in the body of any person is updated. For a woman, this update occurs once every 3 years, and for a man once every 4 years. According to this theory, the sex of the child will be the same as that of the parent whose blood at the time of conception was “younger”. That is, it is necessary to divide the age of the mother by 3, and the age of the father by 4 and compare the numbers obtained. In this case, it is necessary to take into account cases of large blood loss (donor blood donation, abortion, surgery) and the age should be counted from the date when it occurred.
In the old days, when there was no talk of medical research, the only way to know in advance who would be born was the comparison method. More than one generation of pregnant women compared their sensations and external signs, and then derived certain patterns. Modern future mothers believe in some of them.
For example, it is believed that if a woman becomes more beautiful during the child's pregnancy, then a boy will certainly be born to her, while the girl “takes the beauty” from the expectant mother. Not less popular sign, which indicates the sex of the baby, is the shape of the abdomen. If you believe, you will accept that during the boy's carrying the belly becomes more acute, and a round tummy is formed if a girl "settled" in it.
Also to recognize the sex of the child helps the taste preferences of the future mother. If a woman during pregnancy gives preference to meat, salty dishes, then, most likely, she will give birth to a boy, and mothers who are expecting a girl are usually drawn to sweets and baking. Whether it is possible to determine the sex of a child by such dubious signs remains a big question. One thing is known for sure - either a girl or a boy will be born.
How the heart tells
It is believed that in determining the sex can help the heart of a child. So, if a tiny heart beats at a frequency of more than 140 beats per minute, then most likely it’s a girl, and if the frequency of contractions is less, it’s a boy.
In any case, the question of which week the sex of the child can be determined is really important only in those circumstances when the urgency of this information is justified by medical indications.In other cases, it does not matter at all what gender the baby is, because the main thing is that he was healthy!
