The sperm unites with the Ovum in the womb, to form a zygote, which is the beginning of the Embryo.
When sperm coming from the testis of a male person happens to enter the tube where the egg is , one sperm may unite with the egg.

Conception
When a sperm cell and an egg cell unite they form a zygote which now has the DNA it needs to divide and form a new individual. The sperm cell and the egg cell have one half the amount of DNA necessary to form a new individual.
Fertilization
Two sperm, one egg - no. Two sperm, two eggs - yes.
The union is called fertilization and only one sperm can fertilize an egg.
