I believe each of us has had this question, that is, where did we come from?

Some parents joke with their children that they picked it up or bought something to give it away, but they don't know how to explain it.
When people grow up and learn physiological hygiene knowledge, they know that we grow and develop from fertilized eggs.
However, the combination of sperm and egg is single, that is, among the countless sperm, only one dominant sperm will combine with the egg, so where does the remaining large number of sperm go?
Today we will take a look at this issue, I believe that everyone who learns the truth will be as crying and laughing as I am.
From the point of view of women's physiological structure, the distance from the vaginal opening to the uterus is not very long, in fact, this is already a very long distance in the structure of the human body, let alone for extremely tiny sperm.
Only sperm that are sufficiently powered can swim to where the egg is, and such sperm is rare.

There are also male comrades who do not pay attention to exercise, or are very homely, or do not pay attention to physical health.
As everyone knows, the sperm produced by such a person itself is not only low in quantity but also of poor quality, plus the vaginal environment is acidic, and it will be acid to death if you can't withstand such an environment.
Therefore, to be able to conceive successfully, it must be sperm with sufficient advantages.
Otherwise, it would have been survival of the fittest long ago, and it would not be possible to become an embryo.
People are strong from birth, stronger than their competitors.
So understand how good you are!
Do you think life is magical?
What do you think about this?
