When sperm reach an egg, there is a competition to get into the egg first. Since sperm travel in groups, theres a lot of competition. Once a sperm has penetrated the membrane, the membrane hardens, blocking the rest of the sperm out. Once inside, the sperm releases its genetic material, and the egg cell divides, and will continue so until a new baby is born.
when a sperm cell unites with an egg cell it fertilizes the egg cell
Fertilization
Fertilisation is when the sperm cell and the ova fuse together to form a zygote.
Generally, one sperm cell and one egg cell unite for each offpring that is created (some cases, such as monozygotic/idential twins, are different). This means that if a human has one baby, it was one sperm and one egg. Or if a dog has 5 puppies, it was 5 egg cells and 5 sperm cells that united.
The gametes, or "sex cells" - the sperm and ovum (egg) - become the fertilized egg (zygote) when they fuse.
The process when an egg cell and a sperm cell COMBINE is called Fertilization
Fertilization occurs when a sperm and egg unite.

During fertilization the sperm unites with the egg. This typically occurs in the fallopian tube.
