Conception
Zygote
Only one sperm unite with the egg at a time and this process is called fertilization. A zygote is formed after this union which later on develops in to an embryo.
This is called the zygote. As it divides, it forms the embryo.

millions of sperms cell unite with egg cell.......okie??millions of sperm cell
The head of the spermatozoa buries itself in the egg and the tail drops off. At the exact same moment the surface of the egg changes to prevent any other sperm from entering it. The coating of the head of the sperm then opens and the DNA is released and the egg becomes like a new cell with a new set of DNA in addition to its own. The egg then begins to split and split again, and again and again until a human is created.
Fertilization occurs when a sperm and egg unite.
