Standing out from the 300 million small tadpoles, do you dare to say that you are not good enough?

After applauding for love, the small tadpole tree released by healthy men can release 300 million small tadpoles, but only one can win, this competition of small tadpoles has also tried, but in the end it still can not keep up with the large troops are eliminated, the small tadpole tail swings a thousand times to advance a centimeter, the distance to the egg is about eighteen centimeters, equivalent to an adult swimming five kilometers, when the small tadpole comes to the first level, whether it can continue to move forward, but also depends on whether the cervix is open, only before and after ovulation, The cervix will open, through the cervix to have a chance to reach the end, and the cervix is full of mucus, these mucus will swallow some of the weak little tadpoles, only the strongest little tadpoles can pass, and at the same time encounter the goalkeeper of the second level, the white blood ball is another obstacle to block the small tadpole, they will swallow the foreign body in the human body, the small tadpoles are often killed by their poisonous hands, most of the small tadpoles have fallen in the first two levels, the rest have to come to the third level, choose left or right to determine the next fate of the little tadpole, The egg will only appear in one of the fallopian tubes, and the small tadpole in the wrong direction will be doomed to fail to meet the egg, and the fallopian tube is covered with dense cilia, which will also stop the small tadpole from advancing.

When the little tadpole reaches the egg range, that is, the link of the life race, only about five hundred lucky people of nearly 300 million small tadpoles can reach here, and at this time, the fight is vitality, and the egg was once used to test the vitality of excellent small tadpoles, who first passed through the outer transparent bag, that must be the best person.

Once inside, the zona pellucida will quickly step to prevent other small tadpoles from entering, and when the small tadpole is inside, it will quickly meet the egg, and the two will gradually fuse, forming a fertilized egg in about twenty-four hours until it develops into an embryo.
