Scientists discover the secret of determining the sex of the fetus in semen for the first time
In a major scientific precedent, Japanese researchers said that they were able to sort out the sperm that produce males from those that produce females in the semen, which may allow controlling the sex of the fetus in the future, but this matter will bring catastrophic population consequences, if it is applied between Humans.
According to what was reported by the British newspaper "The Telegraph", the chromosome or chromosome (x) that leads to pregnancy in a female, when it meets another chromosome of type (x) from the egg, carries an important molecule that can be controlled and transformed into a decisive element.
And the study, which was carried out at the Japanese University of Hiroshima, stated that this molecule, which is in the (x) chromosome, can slow down its movement, through a catalytic process.
The moment the sperm enters to fertilize the egg
On another level, a chemical could be added to some of the sensors in the semen, and then the male Y chromosome, moving quickly, would completely separate itself from the slow female chromosome.
And when this experiment was conducted among mice, through artificial insemination, that is, by taking the rapid chromosomes, 90 percent of the births were male.
As for the selection of slow chromosomes, 81 percent of female births were obtained, and this means that the technology allows for great sex control.
Scientists are betting on this method in the agricultural field to help produce useful cows in the dairy field, or to produce calves for consumption.
Researcher Masayuki Shimanda explained that this technique has been applied before among cows and pigs, "I think it could become available in artificial insemination of humans. But we have to discuss this issue from an ethical point of view, before we take this step."
British experts warned of this step, even if several countries in the world allow some techniques to determine the sex of the newborn, such as the United States.
And the researcher at the University of Kent, Peter Ellis, believes that if this technology succeeds among humans, it will lead to social unrest of great danger.
Those who reject sex-determination techniques say that its application could lead to an imbalance in the demographics, such as an increase in the male rate or a decrease, according to people's desires, and then the marriage relationship may be affected, and fertility will automatically decrease.
