Let us take a look at Japan scholars in the \"sperm and egg love story\".
When the egg and sperm meet in a specific time, pregnancy begins. Hundreds of thousands of eggs and one only in the hundreds of millions of sperm are selected, arrangements of love this is destiny. We first introduce \"fertilization\" story.

Shoot precise and penetrating terms of ovulation, fertilization
Women are born with eggs
Women\'s body have two ovaries, one around, eggs in the ovary (pocket of the packed eggs). Amazing is that ovarian already exists in the fetal period, and that there were 7 million of the original egg cell. This, in later years is slowly reduced, reduced to 2 million by the time of birth, puberty were only 500,000.
Eggs in the egg, and the other surrounds the egg cell. Born in women previously, eggs in growth in the warm eggs, calm and Enron fell asleep in the future, \"select a month, becoming someone\'s bride\", that has been looking forward to this day.
Only once a month, emerged from the number of hundreds of thousands of. So first, we look at the birth of her first.
Once a month in ovulation, eggs
Woman\'s body, once after puberty, once a month, incredible things happen. Hundreds of thousands of eggs in the end only one egg matures. Which egg cells are selected, only the gods know sth
This month was selected by her, bathed in the egg load in the Mongolian grew. Wait until she was fully mature, there will be a large number of produce progesterone hormones, so that has been broken siege, watching the bride\'s eggs, like her carry to leap out from the ovary, embarked on a journey and brother of sperm meet. This is the \"ovulation\".
After the leap out of the mature egg from the ovary, large open mouth like a horn tube of egg entrance issued in respect of her lure: \"here. \"Eggs is naturally flowed into the fallopian tube. She met the fate waiting in the fallopian tube expansion of section.
Sperm and egg meet, sth >>> their time just 24 hours; the best match for sperm and eggs
Eggs of about 0.1 mm in diameter, in human cells is very large, with the naked eye can see a white spot. In the fallopian tube is wider, egg waiting for sperm. Time at the moment moment in the past, she only short time of 24 hours.
In General, 2-4 days of sperm in the ejaculate, eggs in the 24 hours of ovulation, is sperm-egg binding time limit. After this period of time, the egg had to die alone.
This time, egg suddenly appear around the commotion, she felt there was a lot of things surrounded in their four-week, and that moment, feel the heat in the body, who entered the egg\'s body is this? \"Meet for the first time, egg sister, my brother is your sperm. ”
2 people to see at a glance pumila goodwill, fell in love. In fact, at this time they had finished the sperm-egg binding. In fact, brother of sperm and egg meet sister, has been a campaign of harsh competition, is always waiting for the egg of the unimaginable. And the egg meet. Sperm brother the struggle of what is it?
In order to meet the egg, sperm are beginning to fight
Volume of an ejaculation of semen, perhaps 1~6 ml, which contains the sperm count is 100 million ~2 million, the individual size of about 0.5 mm. They had at the moment of ejaculation will instinctively know their fate.
\"We wish only one. And eggs is met, and integration of new life. ”
But competition competitor has 200 million, only faster and more powerful, better a man can win, this is a more harsh than the Olympic competition.
After entering the woman\'s vagina, sperm are immediately began a long swim from vagina to swim to the entrance to the uterus. Where mother secrete a nianhu liquid, this mucous into a net, egg ran out of time, the network was open, sperm it is easy to pass. This network has played an instrumental role, help sperm continue upstream. In addition to the ovulation within about 24 hours after, other times, the network is closed, prevent sperm from entering the uterus.
Successfully passed the \"hurdle\" is about ejaculation of sperm of 1 per thousand. After that the tour speed ahead of their 2~3 mm per minute, this is how human leisure, but small sperm have is to make every effort to \"fly\"-speed forward. At this time, backward of the number of sperm is not: stop for a rest in the middle of some physical bad; some energy long ago abandoned; there are in Zhan; some are going in the wrong direction. To the end, had been swimming with sperm, the number is less than 200.
Fine eggs of brother and sister in love sth >>> birth of albums (many plans)
In the sperm, a model of the x chromosome x sperm and type y to y chromosome sperm. Although there is a y sperm faster, but after ejaculation, live more
Is x-sorted sperm for a long time. Which one is easier to love and eggs, it is not clear at this time. When the expansion is going to swim to the fallopian tube, see egg of sperm, and in front of the egg, dispersed desperately forward. That time, the egg is surrounded by a transparent shell, in this next to the cell groups called Cumulus cells around. Sperm to break through Cumulus cells, transparent surrounds the egg with melted it. Break the zone enters one of the earliest, and the egg.In this way, from the vagina to the uterus, fallopian tubes, takes about 100 minutes of time, the fastest, strongest players getting eggs out of love. But fertilization does not represent the establishment of the pregnancy. Since then, the two people together on the journey of pregnancy.
Implantation
Fertilized eggs to explore the new journey
Rely on combined fertilization, sperm were brother and sister the eggs become fertilized eggs. Rely on the movement of tubal, eggs from two meeting places to the settlement-of-uterus. During this period, Zygote side vision reaches the uterus happy, like Mulberry fruit split.
The other hand, in utero, bred new life preparation in full swing. Bed of fertilized eggs-the endometrium, in the role of the female hormones become soft, like a sea under lucrative.
Fertilization in about a week later, fertilized eggs in the endometrium to seek out your own points, and Enron to enter. It fully enters and implantation in the endometrium, so that the pregnancy has been established. In fact before moving into the new House, fertilized eggs will encounter difficulties. Sometimes, demons will hand out blocks sperm and eggs 2 were in stable relationships; sometimes, new home improvement enough, and prevent fertilized eggs from living at ease down. Marriage encounter setbacks was a little regret, this cannot succeed often occur in pregnancy.
Live a new life, pregnancy begins
After settled down, new life begins for sperm and eggs, this also means that pregnancy begins. Since then, 2 shall be one flesh, approximately 40 weeks of time to nurture a new life.
Human fertilization, implantation, is filled with the mystery of life, people do not know all of what happened in one\'s own body. Again and again by chance, again and again of fate only contributed to the sperm and egg meet, only like this everywhere can see the baby was born.
Life so easy, we can look forward to your baby\'s growth is not full of love you?
