It turns out that it is the egg that determines which sperm to choose to conceive

Before that, we still think that any sperm is healthy, so it will catch the eye of the egg sister. It turns out that the egg tends to attract a special sperm.

We know that, when an egg meets a sperm, it forms an embryo and after a certain period of time the baby is born.

It sounds like a simple sound, but the truth is not so simple. Because you know that, to have such great achievements, the egg had to "headache" to choose the sperm suitable for her.

Race of sperm.

The biologist Scott Gilbert of Swarthmore College said that the egg had to take part in a conversation, conquer sperm, not simply "catch" the sperm and bind it.

Therefore, fertilization is not really a mere conquest but it is like a fair race between individuals.

The race of sperms to meet the egg sister

Those of us also understand that there is a fierce race of sperms towards the eggs. When the egg is at its healthiest stage and falls off, the sperm cell hurdles successfully into the body - this time the race officially begins.

The egg has only one but there are millions of spermatozoa rushing to "die". When the X sperm meets the egg in conception, a baby girl will be born, and if it is Y sperm that connects with the egg - the baby is definitely a good guy.

The egg has only one but there are millions of spermatozoa rushing to "die".

But the story is not so simple, because the fact is, eggs can reject sperm.

Therefore, this race is not really fair. Because "winner" has been decided beforehand. Or simply understand, the egg has chosen the sperm that it will allow into the pair.

Dr. Joseph H. Nadeau said that eggs are not obediently waiting for sperm to conceive, whereas eggs themselves are a key factor "deciding" this game.

The egg has chosen the sperm that it will allow into the pair.

According to an explanation of the Pacific Northwest Research Institute, eggs like or dislike a sperm sperm will make sex selection at the cellular level more complicated.

However, we can give two possibilities for this situation. First, it is the attraction between sperm and eggs mainly related to folic acid molecules.

It is the metabolism of different vitamin B or folic acid in eggs and sperm that determine the attraction between them.

It is the metabolism of vitamin B or folic acid that is different in eggs and sperm.

Secondly, sperm is present in the female reproductive tract as they approach the egg. Even so, it is possible that eggs have not been fully developed during this time.

So eggs can affect cell division so that their genes match sperm.

Therefore, experts say, with this discovery will help us better understand the process of pairing the egg and sperm sperm to make 1 baby born.
