These sperm surrounded by an egg, but after one of the sperm into the egg to form a fertilized egg or Yunluan, other sperm should not be able to enter.  Fertilized egg will move with the tubal peristalsis uterus, and implantation endometrium, in endometrial continue to develop.  To complete this process known as "conception."  To "Guashudila", a new life will come human.  Thus, a new birth, you must meet three basic conditions. First, both men and women can produce and to emit a normal sperm and eggs; Second, sperm and egg meet inside the fallopian tubes must be combined and fertilization, which requires fallopian tubes must be unobstructed; Thirdly, it is good for growth and development of fertilized eggs in utero environment, .
