When the sperm penetrates the egg, the surface of the egg changes so that no other sperm can enter. At the moment of fertilization, the baby's genetic makeup is complete, including whether it's a boy or girl.

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
no. he/she cannot coz' a human being has 46 chromosomes 23 of which comes from the mum, 23 comes from the father. a sperm is strictly composed of 23 chromosomes, haploid of the 46. other reason is, fertilization suggests that only 1 sperm can penetrate a single egg, that's anti polyspermy. so f 1 man had sex with a woman then it's sperm will penetrate the ovulated egg, and the next man's sperm will never have the chance to penetrate the egg so is true with the other sperms of the first man.
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 only one sperm can fertilize one egg.
Sperm has enzymes that breakdown the outer coat of the oocyte. It takes many sperm with all their enzymes working together to accomplish this.
Sperm cells fertilize the ovum, they are not fertilized. The primary reason for how the term is used is because most sperm compete to reach and penetrate the egg.
If the sperm are not "healthy" or present in enough numbers they will will not have the ability to reach and female egg and then penetrate and fertilize then egg.

a man can release millions of sperm at once,however only one sperm can fertilize an egg
To fertilize an egg, one needs live sperm. If there is no meeting of sperm and egg, there can be no fertilization.

no,sigle men single sperm fertilize fimale egg.
The shape of the sperm is a component needed in order for the sperm to penetrate the layers surrounding the egg. Each sperm needs a head, tail, and mid-piece.
sperm cells are found in the soil to fertilize the eggs
