      经过9个月的旅程,,婴儿已经可以品尝、听闻、触摸和学习。266天后,当她柔软的身体感觉越来越拥挤和不舒服时,她只能通过一种方式来到这个充满明亮灯光,喧哗气息和寒冷空气的未知世界。
      这就是她的故事。当两个细胞结合时,便注定了女婴孩将在妈妈的子宫里度过9个月,然后出生。在短短的38周时间里,她从一个单细胞发展成有200多种特殊种类的万亿细胞到最终形成一个无比复杂的婴孩。
      我们可以通过新型的三维或者思维技术透过子宫观察婴儿的发展。科学观察的实时计算机成像技术将带领我们体验一项从未有过的旅程-观察胚胎在子宫里面更加复杂的行为。我们可以观察到婴儿开始笑,辨别她妈妈的声音,甚至是做梦。妈妈为他提供住的地方和一些必须的东西,比如食物,水和氧气。但真正的开始却还是胎儿自己,从受孕的那一刻起,在不同的时间,胚胎开始形成,分化再到一步步的成长。
      一个成熟的男性将会生产50亿个精细胞。每一个精细胞都会携带男性的遗传基因密码。精细胞的质量跟男性的生活方式有很大的关系。如果没有抽烟,过量饮酒和穿紧身裤的习惯,那么男生将会产生更加健康的精细胞。相反,咖啡可以刺激精细胞游离的更远更快。精细胞的游离是一个缓慢的过程,人体内的小细胞游离的速度是每分钟0.1寸。卵细胞从阴道穿过宫颈,到达输卵管等候着精细胞的到来。每个月,女性卵巢都会释放出一个携带她自己遗传基因密码的卵细胞。
      精细胞是通过什么方式找到卵细胞至今仍是个迷。最近的研究表明,精细胞有一种嗅觉能够找到卵细胞。这个旅程很漫长而且很艰辛,只有一部分精细胞能够残存下来。在真正受孕前大概需要10小时的时间。第一时间到达卵细胞的精细胞是最强壮的,第一个穿透卵细胞表面的精细胞才是真正的大赢家。
      一旦精细胞进入卵细胞后,将会引起卵细胞膜的变化,使得其他的精细胞不能进入卵细胞而最终都会在一周内慢慢死去。一旦精细胞核酸“侵入”卵细胞内,这两个细胞就逐渐优雅的融为一体,此时正是受孕的开始。一套唯一的以前从未存在将来也将不会被复制的DNA也就形成了。

        This baby has come to the end with 9-month-long journey. She can already taste, hear, smell, touch and learn. After 266 days, her soft cocoon has grown increasingly cramped and uncomfortable and there is only one way out into the unknown world of bright lights, loud noises and cold air, and there is no turning back. This is her story. He seem inside her mother’s womb from the moment two cells frozen into one to the birth of the baby girl in just nine months. This baby is about to begin the journey of life time; have spend nine months hindering in her mother’s womb. In just 38 weeks, she is transformed from a single cell into trillions with over 200 specialize types organized into an incredibly complex form of an infant girl. Using new three-D and even 4-D scan techniques, a window is open on the womb, allowing us to see fetal development onfor before our eyes. Real footging computer imagine based on scientific observation take us a journey inside the womb as is never been seen before and reveals fetus behaves much more complex way than previously imagine. Dooring her adsy in the womb, she was smile, recognize her mother voice and maybe even dream. Her mother provides the shelter and the basics; food, water and oxygen, but the real start of the show the fetus herself. Building, dividing and growing according to the intercoms plans created at the moment of conception. here how it begins, during her ejaculation,a mature healthy man,expels up to 5,000,000,000 sperm inside woman’s vagina. Each sperm carries a precious cargo, the father’s genetic code. A man’s testes are constantly working turning out over thousands sperm every second. The quality of the sperm depends on the man’s life style. If you avoid smoking, excessive alcohol, hard bass even tide underwear, you produce stronger healthy sperm. Coffee, on the other hand, purely stimulates the sperm to swim further, faster and harder. It is a slow journey for the sperm, the small cell in the human body, they travels one then of the inch per minute and the hurdles every turn.  From the vagina, they pass through the cervix, open to the uterus, and all into the fallopian tube were the woman’s egg. The largest settlement of the body awaits. Each month, a woman’s ovaries release one egg that contains her own genetic code. She made these eggs when she still feed herself that’s all beside her own mother’s womb.
       

        And they became Campton storage ever since though childhood, adolescence and dot hood,ready to burst into life. How these sperm find the way to the egg is something remains mystery. Recent research indicates that sperm has a sense of smell and can sleef their way to the egg. But the journey is so long and arduous for the sperm and only a handful survives. It may take up to ten hours before the actual movement of conception. The first sperm to reach the egg are the strongest and feedest, and first though the egg surface would be the winner. There are no prize for coming in second, the instant once sperm enter into the egg, it trigger change in the egg membrane make it impenetrable to all other sperm, which all die off within a week. Once within the gall, the sperm nuclease strong tort the eggs, the two cells gradually and gracefully become one. This is the moment of conception. Within individual, unique set of DNA is created. A human’s signature has never existed before and would never be repeated.
