Pregnancy: Female or Male? How to know it immediately through a simple search. The science that reveals the sex of the unborn child even before 3 months, can we? Find out how

What do we think, after discovering that we are waiting for a nice baby? The first question that comes spontaneously, instinctively, is to know whether it is female or male. We begin to fantasize about the sex of the unborn child, “Will it look like me or dad?” “If it is a female we will call it that, if it will be a boy instead …” In short, after the initial surprise of the pregnancy, to know if we will have a sweet princess or a “brave” prince by our side, is what (almost) every parent – mothers first – dream of knowing right away! Usually to know if we will have a Female or a Male, we must wait for the first 3/4 months of gestation, when the genital apparatus of the fetus is complete but, we cannot always know with exact certainty. How many times has it happened that, in view of the fateful ultrasound scan that would have revealed the sex of the child, the latter has turned his back or with his little legs crossed, and therefore difficult to establish his sex? It will have happened to many of you. The baby starts to spite us! But seriously, can there be a sure way that will allow us to discover in advance if our future little child will be a she or a him? Science has come to meet us in this, and yes, there is a way! Want to know what it is? Just read on and find out

Pregnancy: how is the sex of the unborn child formed?

Knowing whether we should buy a pink bow or a blue bow it may not take long. In fact, if we first had to wait at least the beginning of second trimester of pregnancy, now science has made great strides. In fact, only 8 weeks of gestation would be enough to find out! But before talking about this and what are the methodologies and tests on biological bases used to understand the sex of the unborn child, it is better to take a step back and explain when and how the genital apparatus of our small fetus is formed.

Perhaps not everyone knows that the sex of the fetus is determined immediately, in practice at the moment of conception, when the female egg is fertilized by the male sperm. To “decide” whether a boy or a girl will be conceived is the father, as it is the type of chromosome of the sperm that determines the sex of the fetus. Both the female and male sex cells are in fact equipped with 23 chromosomes which, by joining together, form the Dna (ie the genetic heritage) of the child and establish not only the characters (such as height, face shape, eye color), but also sex. Of the 23 chromosomes, 22 contain information for bodily development, while the twenty-third pair contains the gene sequences for the development of internal and external sexual organs. These two sex chromosomes, designated by the letters X or Y are therefore decisive for the sex of the individual. In a female, this pair consists of two relatively large chromosomes, called X, while in the male we find an X chromosome flanked by another, much smaller and asymmetrical, called Y.

Sexual cells (ovum in the female and spermatozoa in humans) possess only half of the chromosomal outfit, therefore 23 single chromosomes, due to the meiotic division that occurs during their formation. Thanks to this division, when the egg and the sperm join together, the resulting cell, called zygote, contains a complete set of 46 chromosomes (23 pairs). During gamete reproduction, the distribution of the individual chromosomes is CASUAL: the mother, being endowed with the XX pair, will always transmit the X chromosome, while the father (XY) will produce spermatozoa Y and spermatozoa X.

In practice, each female somatic cell contains 2 X chromosomes, while each female gamete (ovule) contains only one. In the father all the somatic cells are characterized by an X chromosome and a Y chromosome, while the sex cells can contain either an X chromosome or a Y chromosome. When an egg, with its chromosome X, fuses with a spermatozoon endowed with the Y chromosome, a male will be born ; when instead an egg melts with a spermatozoon containing another X chromosome, the unborn child will be female.

In other words, during conception the presence or absence of the Y chromosome in the paternal spermatozoon determines whether fetal development will proceed, respectively, towards the male or female line. The sex of the unborn child therefore depends exclusively on the genetic contribution of the father. The question of whether the sex of the fetus can be influenced through a particular diet is very controversial.

What happens in the first two months of Pregnancy?

All ‘beginning of pregnancy it is difficult to establish the sex of the unborn child since in the embryo substantial differences between the two sexes are not yet recognizable. It is very likely that a sissy is easily mistaken for a boy, since the clitoris in the early stages of pregnancy is very similar to the male genital organ, it is in fact stretched and, therefore, easily exchangeable with the male genital organ. That’s why they expect the first eight weeks of waiting. S holo to 7th week the embryo begins to develop in a feminine sense. Around the 12th week of pregnancy, instead, the differentiation of the male and female genital systems is completed. From this moment, through villocentesi (which can also be anticipated at the 9th week of gestation), amniocentesis and ultrasound it will be possible to know if a boy or a girl will be born .

Will it be Female or Male? Test response to 8 weeks and other scientific studies

Just wait for the first few months, a new test for a few years – non-invasive DNA-based prenatal screening ( Non Invasive Prenatal Testing NIPT ) – allows you to know it already at 8 weeks of gestation. The test analyzes, with a simple blood sample, the fragments of fetal DNA that circulate freely in the maternal blood. The non-diagnostic but screening test, for now, is used, rather than for the determination of the sex of the fetus, to analyze the probability that it is affected by the most common non-sexual chromosome abnormalities, such as trisomy 21 (Down syndrome ). It is a very rapid, painless test and practiced more and more in analysis laboratories. Now the test has become even more immediate: just a drop of blood taken from the fingertips of the mother to determine the gender of the unborn child. Researchers from Sabin Laboratory a Brazilian company specializing in medical diagnostics, have shown that a superficial puncture such as that of a stinging pen used to measure blood glucose is sufficient for to establish the sex of the fetus with a ‘100% accuracy : the test was carried out on 100 women at the eighth week of pregnancy.

But how does this non-invasive test work? In practice, in the drop of blood taken the search for the Y chromosome, present only in male DNA. When present, the fetus is male, when it is absent a female is expected. Now the team of scientists is already checking if the same rapid procedure can be used to exclude also Down syndrome. The test will serve not only to appease the curiosity of future parents but, more than anything else, to monitor pregnancies at risk of genetic diseases closely related to sex : for example, only males inherit the dystrophy of Duchenne from a healthy carrier mother. However, a simplified NIPT could favor cases of selective abortion based on the gender of the child, already widespread in some countries of the world (such as India and China). Knowing early if you are expecting a child risks making the practice more common.

Another scientific study that is based more on probabilistic calculation comes from Canada. According to this 2007 Canadian study, for example, it is sufficient to determine in what position the fetus is implanted: the research, conducted by Dr. Saad Ramzi Ismail of 5,376 women over 10 years, has established that in 97% of cases if the implant is on the right side of the uterus it is a male, while the females implant themselves on the left.

And if it was all a question of the seasonal temperature?

Other studies have shown that in more females are born, while in the warmer years more males come to the world; and again, in the countries closest to the equator more females are born while the relationships are reversed as you go up towards the Poles; that black men more easily become fathers of a female whereas Asians are more likely to conceive a male; that heavy smokers bring more females into the world. And finally, that among marathon runners, fighter pilots, astronauts, pesticide-using peasants, ship carpenters and workers exposed to heavy metals, more females are born, just as more females are born during periods of economic crisis or famine and among mothers than before of pregnancy have been victims of traumatic events.

Ultimately, according to the study, the common trait of all this research is that, while normally the birth rate is 100 females for every 125 males, under conditions difficult environmental proportions change in favor of weaker sex : little money, little food, stress and pollution (in addition to decreasing the overall fertility rate, which is therefore compromised) bring the ratio to 100 girls for every 105 males. The explanation is that the “weaker sex” is actually much less fragile when it comes to adapting to difficult living conditions: in fact, at the time of birth, females weigh an average of 100 grams less than males, and need less nutrients to stay in life and to grow in health.

The old myths about the sex of the unborn child: it will be female if …

The old myths about the sex of the unborn child are hard to die: despite numerous researches have denied superstitions even today in popular beliefs many of the “divinatory methods” used to guess whether the baby will be a boy or a girl resist. From skin health to mood, hair color to pendulums and the Chinese calendar: history and traditions are full of anecdotes and strange beliefs on how to discover the sex of the baby.

According to these beliefs for example, if the belly has a pointed shape it is a male while it is a female if it is more rounded ; blue bow if the belly is low and pink bow if it is high; the unborn child is a boy even if the hair on the mother’s body increases while there is no variation if it is a sissy; it is female if during sleep they dream of males and vice versa. And again, the bow will be blue if the mother has the coldest and pink feet if there has been no variation; male if the skin is smooth and female if the pimples come, boy if you sleep on the left side and sissy if on the right, male if the left breast is smaller than the right and female otherwise … In short, everything is the opposite of everything .

The differences between waiting for a male or a sissy would also appear in the health status in the onset of small disorders typical of pregnancy and in the physical appearance of the future mother . For example:

  • look at your hair: during pregnancy they are probably much brighter, thicker and brighter, but if reddish reflections appear it could be the sign that you are waiting for a girl
  • look at your skin : if your face is suffering in particular from the hormonal changes typical of pregnancy and is filled with acne, pimples, skin dryness you could wait for a female, while if the skin seems smoother and brighter than usual you will wait for a male.
  • Measured your breast : according to an American scholar, when a woman expects a child, her breasts would increase during pregnancy, on average, by eight centimeters, whereas if she is waiting for a boy the breast would not increase more than 6.3 centimeters.
  • keep an eye on your partner: if he is putting on weight and starts having bacon it could mean that you are waiting for a baby .
  • Make this calculation: add the number of your years at the time of conception and the number of the month in which the conception occurred. If the result of this sum is an odd number, a female is coming; if instead it is an even number you are waiting for a boy.

Even the typical wishes of pregnancy those that make you crave for chocolate in the middle of the night or pop horn at breakfast could be the distinctive sign of a male or female:

  • if you feel like proteins cold cuts, cheeses, salty foods could be coming a male
  • if you can’t resist sweets, orange juice, fruit is likely to be coming a female.

Even the famous pendulum game has been used for generations to predict the sex of the unborn child: you can use a wedding ring as a pendulum after hanging it on a chain and making it move on your belly:

  • if moving the pendulum forms circles look for a male;
  • if faith moves from a side to side a female was to come

Finally, watch out for when you hear the first movements of the fetus in the belly: if you warn them very early they are told to wait for a male ; if you hear them after a certain time you could wait for a girl .

And the moon phases? Some believe that phases of the moon can influence the probability of conceiving a male or a female. In particular, if conception occurred during the crescent moon the greater the chances of having a female, whereas on the contrary if conception took place during the waning moon the probabilities would be higher to have a male.

Pregnancy: tips for conceiving a male or female

Scientific research has highlighted some differences between spermatozoa Y and X; the first (masculine) would be smaller and faster, but not very resistant, while the second (feminine) would be slower, but stronger and longer-lived. Based on this premise, some precautions could offer a greater probability of conceiving a child of a particular sex.

In particular, to help the conception of a boy, would be useful:

  • consuming reports close together,
  • concentrating intimate relationships on the day of ovulation
  • during intercourse, adopting a position that involves deep penetration

Conversely, conception of a sissy would be favored by:

  • consume infrequent intimate relationships;
  • consume intimate relationships in the pre-ovulatory period;
  • adopt a position that involves a shallow penetration during the relationship.

Although based on a scientific assumption, such however, techniques lack scientific confirmation regarding the real effectiveness. But, you know, trying never hurts!
