If we consider the egg cell as a planet, this massive firework would be even more powerful than the explosion of the Cretaceous asteroid that hit Earth and destroyed all the dinosaurs – this lightning could spread
Studies have shown that during the development of egg cells, hundreds of billions of zinc atoms are stored in vesicles on the surface of egg cells, accounting for 90% of the zinc content of the entire egg cell.
It is unclear what the mechanism is that causes this phenomenon, but from a philosophical point of view, it is consistent with the fact that nothing will succeed by chance.
Taking yourself as an example, first of all there are about 100 to 300 million of your `brothers and sisters` in about half a teaspoon of semen entering your mother’s body.
Even though the number of sperm is up to hundreds of millions, facing such a long distance, and to fight, you have to spend a lot of energy.
Next, you will encounter a bigger challenge: white blood cells in the mother’s body.
The swimming speed of sperm is about 2 to 3 mm/minute, when compared to your mass at that time, this speed is quite astonishing.
After a long journey and going through many levels of challenges, eventually hundreds of sperm will reach the egg cell sisters. Compared to the giant army when they set out, this remaining number is insignificant.
But even so, it’s still not easy to become the final winner.
Although there may later be hundreds of sperm bravely moving forward, if they get inside, the egg cell will immediately react, the entire zona pellucida will immediately harden and all the sperm
At this time, billions of zinc atoms stored on the surface of the egg cell will be released immediately, and a magnificent fireworks display will break out.
This was first discovered in 2014 in mouse zygote research and in 2016 when observed during egg fertilization in monkeys and was later found in cattle and humans, recent research shows.
So when you come to this world, it actually starts with a huge explosion comparable to the explosion of a giant asteroid hitting Earth.
In addition, the research team discovered that the size of this `zinc` explosion will greatly affect the quality of fertilization of the embryo, so the only difference in this terrible explosion is the strength of the explosion.
