The fact that only one sperm can fertilize an egg.
After the sperm enters the cytoplasm of the oocyte, the cortical reaction takes place, preventing other sperm from fertilizing the same egg
The sperm is incompatible with the female eggs, and would not interact with it.

Yes, sperm can enter the uterus without fertilizing the egg. Just because a woman is fertile doesn't mean she will fall pregnant, there are a LOT of things that can go wrong to prevent pregnancy such as poor sperm quality or there not being enough sperm reaching the egg to fertilize it.
Ovum has a layer of zona pellucida around itself. When a sperm enters the ovum, the cortical granules present in the ovum, causes the thickening of the zona pellucida. This prevents the entry of other sperms in the ovum and only one sperm is able to fertilize the egg.
Yes, it is possible for 2 sperm to reach the egg, however only one will fertilize the egg. It isn't uncommon for more than 2 to reach the egg, depending how are along the egg is down the falopian tube. And how much sperm was ejaculated.

It is important that only one sperm fertilizes an egg to ensure the correct number of chromosomes in the resulting embryo. If multiple sperm were to fertilize the egg, it would lead to an abnormal number of chromosomes, resulting in genetic disorders and potential miscarriage.
Puberty.
Yes, sperm that has not reached full maturity can still fertilize an egg. While fully mature sperm may have better motility and function, immature sperm can still possess the ability to fertilize an egg.
It is because of the nutrients that comes from each other. They been able to fertilize because of the hormones of each other.
I am not sure. But i think you can. But your sperm aren't active. Which means they are not able to fertilize an egg.
Sperm produced by mosses require a film of water to reach an archegonium. The water helps in carrying the sperm to the archegonium, where fertilization occurs. Without water, the sperm would not be able to swim to reach the archegonium.
sperm doesnt expire it just helps if you use a condom so that when you decide to have sex you dont have the sperm inside you trying to fertilize your eggs .
The Ovalry Releases an egg and and the sperm travels through the fallopian tube to meet the egg.When They Meet they form A Zygote then it develops into an Infant
If sperm were to be put in a sperm bank the average life span of a sperm once ejaculated is 4 days however in some cases sperm has survived 6 days and was still able to fertilize an egg.
