The gender of the baby is probably the most interesting question, the answer all future mothers and fathers are so eager to learn. Some are driven by pure curiosity, while other parents want to prepare in advance everything that is needed for a newborn. In which term can you discover the baby’s gender?
What the gender of the child depends onScience says that there are two kinds of chromosomes – X and Y. The X chromosome is in a female egg, while spermatozoids have both X and Y chromosomes. At the time of conception there is a merger and formation of a pair of chromosomes.
Possible pairing options are only two: XX or XY. If the pair is XX – a girl is born, if XY – a boy. So, the gender of the child depends on which chromosome is brought by the sperm into the egg.
The influence of various factors on the gender
Conception in vitro. Before a fertilization of the egg via IVF, the selection of sperm of a particular gender can be carried out.[attention type=green]Time of conception. Sperm with “male” chromosomes are faster, but if the egg is not yet in place, they often die, not having had time for the right moment. But sperm carrying the “girl” chromosome moves slowly, and is more likely to survive. Therefore, for the success of male spermatozoids, conception should happen on the day of ovulation – in this case a fast carrier of the Y chromosome arrives first. If you are dreaming about having a girl, the most favorable time for intimacy is be 2 days before ovulation.[/attention]
Parents age. The gender of the baby, according to statistics, depends largely on the age of the parents:
- if the father is older than the mother, there is a higher chance that they will have a boy;
- if mom is older than dad – a girl.
The mother’s character. Boys often are born to self-confident, strong and energetic moms. A strong character of a woman indicates the presence in her body of a large amount of testosterone, which causes the egg to favor “male” sperm.
Mother’s nutrition. Scientists have developed a diet which needs to be complied with 4 months before conception. It is abandoned after the sexual act, as the diet is needed only to affect the egg before conception, in order to program its “preference.”
- If parents want a boy, the future mom should eat fish, potatoes, mushrooms, beans, pasta, salty foods, peaches, bananas, tea and fruit juices.
- A diet of dairy products, cereals, onions, peppers, tomatoes, fresh fish, crabs, nuts, honey, chocolate, cocoa and citrus juice will help to conceive a girl.
When and how the fetal reproductive system begins to develop
The formation of the reproductive system can be divided into 4 main stages:
- In the first trimester of a nine-month pregnancy, the fetus is just beginning to form. In this period, there is some manifestation of the primary gender cells. They are the basis for the formation of the gender glands, which starts somewhere in the 5th week after conception – the 7th obstetric week of pregnancy.
- In the 8th obstetric week the reproductive system begins to actively develop, but it’s impossible to determine the gender of the child during this period by any means. Ovaries and testicles are formed a little bit later – specifically, in the ninth week.
- Boys will acquire male genital characteristics in the 10th obstetric week. At this time, the testicles begin to secret testosterone. But in this period only the internal genitalia are formed.
- External genitalia begin to grow in about the 11th week. However, boys’ and girls’ genitals in this term of development look the same. Therefore, the determination the child’s gender can only be done in the 14th obstetric week.
When the baby’s gender is determined by ultrasound
An ultrasound examination allows to determine the status of the fetus, detect likely pathologies in the development and, of course, to know the gender of the child. But checking whether you have a boy or a girl, can be done only at a time when the fetus in the womb has taken a correct position.
In which week you can find out the gender of the child? The earliest date on which it is theoretically possible to determine the gender of the baby is the 13-14th week. But the result will not be accurate, since the probability of error is huge – 50% or more. Moreover, future mothers usually have the first ultrasound in the 11-13th week.
By the 18th week, the picture will be clearer, and an experienced doctor can most likely correctly identify the baby’s gender. But on the condition, that the child allows him to do it – because the baby is often covered by his hand, the umbilical cord, he bends the legs or simply takes an awkward position.[attention type=green]The second ultrasound examination is scheduled for the 20-24 weeks. Exactly in this period you will likely be given the correct answer. Many impatient parents may ask, “Why so late?”. The answer is simple – it is related to the process of appearance and development of sexual characteristics.[/attention] In the 9th week, the genitals of girls and boys look exactly the same, because their labial-scrotal folds do not have visible differences.
Only after the 11th week the boy’s penis begins to form. At the same time the girl’s labia are often swollen, so they can be mistaken for a scrotum. All these factors lead to errors and incorrect predictions.
The third ultrasound is performed in the 37th week from the day of conception. After this examination there is no point in inquiring about the gender. Yes, all of the baby’s organs are already formed, but he is folded in a fetal position in anticipation of his imminent birth, so doctors simply can not see anything.
Can an ultrasound make a mistake as to the sex of the child? The probability of a correct gender determination by ultrasound is around 90%.
Invasive research methods to determine the baby’s gender
Существует всего три инвазивных метода. Их суть заключается в анализе биоматериала, и они мало чем отличаются.
- Amniocentesis. In this method, an amniotic fluid sampling is done in the 16-18th week of pregnancy.
- Cordocentesis. Umbilical cord blood sampling is done.
- Chorionic villus sampling. Chorionic villus – which is located in the placenta – sampling is done in the 10-12nd weeks of pregnancy.
Then, the presence of a Y-chromosome (only men have it) is defined in the molecules of DNA in the given biomaterial, which allows for the determination of the future child’s sex with a minimum probability of error.
However, all three methods are very dangerous for the baby, because they are invasive and can trigger the death of the child and health problems in the mother. They are not used just for simple curiosity, because the possibility of a miscarriage is not worth it.[attention type=yellow]Why, then, do we need invasive techniques? They are used only in those cases where the gender of the child becomes a very important issue. For example, if the family has a serious genetic disorder that is passed from generation to generation down a certain line – then you need to know the gender of the future child in the first trimester.[/attention]
