Actually, it only takes one sperm to fertilize the egg, but the problem is the journey to the egg. The male ejaculates so many sperm because most of them die on the way there, the lucky one that gets there cause the fertilization.
Actually all it takes is one, but nature wants to insure that fertilization happens so many are produced to make sure one gets there.
Only one sperm fertilizes the egg.
Only one.
Only one sperm is required to fertilize an egg. One is both necessary and sufficient in order for an egg to be fertilized. But in order to be confident that one will make it, you need a certain minimum sperm count.
Sperm have about three days to make it to the egg for fertilization before the egg passes out of the uterus and dies.
The ovum is bound by many membranes preventing the breakage of it. The ovum contains food which is essential for the developing zygote. It forms a fertilization membrane after fertilization to prevent the entry of the other sperms.

That is a good question. Both egg and sperm has the same number of chromosomes. But then the size of the egg is very big compared to sperms. Here the egg has lot of food material stored in them. that is necessary for cell multiplication after the conception. sperms has to run fast for fertilization. You can not run fast with some heavy weight on your back. Also the number of the sperms is very high and so many big sperms will create the problem of accommodation in the semen.

Sperm cells are produced by millions a day because it takes a many number of them to get through to find a female egg for fertilization. As the male gets older in age, the production of sperm will decrease.
Mates are not needed for reproduction if you are Asexual. Asexual organisms,such as protists and many types of bacteria, can reproduce on their own- one parent- no fertilization is necessary.
Only one sperm unite with the egg at a time and this process is called fertilization. A zygote is formed after this union which later on develops in to an embryo.
because if only a little amount was relaesed then many people would not get pregnant... and only one can survive and that one is all you need,,,,,,
This normally happens in fallopian tube. Many sperms are needed to dissolve the outer coat of the egg. Only one can penetrate the egg to fertilize the same.
