The nuclei of the egg and sperm cells fuse to form the fertilized egg.

No, sperm does not always reach the egg during fertilization. Only one sperm typically fertilizes the egg, while the rest are blocked from entering.
During fertilization, sperm reach the egg with the help of their tail movement and enzymes that break down the egg's outer layer.
BABIES!
During fertilization the sperm unites with the egg. This typically occurs in the fallopian tube.
When an egg or ovum is "ruptured," it is typically released from the ovary during ovulation. If fertilization occurs, the sperm will penetrate the egg, leading to the formation of a zygote. If fertilization does not occur, the egg will disintegrate and be reabsorbed by the body.
Why are there generally more eggs and sperm cells produce during external fertilization thean internal fertilization
The chemical released by sperm during fertilization is an enzyme called acrosin. Acrosin helps the sperm penetrate the protective layer around the egg, facilitating fertilization.
If your question is what happens during fertilization? the answer varies. If your are speaking about sexual reproduction then fertilization occurs when the sperm and egg combine. Basically the first sperm to get to the egg keeps it. The egg hardens to keep excess sperm from entering. (of course some errors can occur which will lead to defects, twins, triplets, etc.) There are many other phases to the reproduction process but fertilization is basically when the egg and sperm combine.
Fertilization typically occurs in the fallopian tube after ovulation, when a sperm cell successfully penetrates and fertilizes an egg. This usually happens within 24 hours after the egg is released from the ovary.
No. Fertilization is the joining of an egg and sperm.
During human reproduction, the sperm and egg fertilization process occurs when a sperm cell penetrates the egg cell, forming a zygote. This typically happens in the fallopian tube after sexual intercourse, leading to the creation of a new individual with a unique set of genetic traits.
