Why is it necessary to release so many sperm at once?

Getting more of your sperm closer to an egg means there is a greater probability that it will be you and not your neighbor fertilizing it. This kind of competition is an evolutionary imperative for males of any species. If a rival’s sperm fertilizes an egg, then an opportunity to pass on your genes is lost.

Why do males ejaculate millions of sperm when only one sperm is required for fertilization?

Why does it take millions of ejaculated sperm to fertilize one egg? Dear Reader, Seriously though, the short and sweet answer is this: the 200 to 600 million sperm normally found in ejaculate increases the chance that some will reach a mature egg, eventually with just one being able to enter and fertilize it.

What causes large amounts ejaculate?

Men usually produce the most semen when they’re in their early thirties. The amount tends to decrease as a man gets older. Heredity, diet, smoking status, and overall health can also affect semen volume. Some men ejaculate more if they haven’t had sex for a few days.

Why is number of sperms produced always much more than the number of eggs?

The number of sperms produced is more than the number of eggs because sperms are motile and they have to compete with one another for their existence. In the end only one sperm fuses with the egg.

How is it beneficial for males to produce very large numbers of very small sperm?

It can, in contrast, be beneficial for males to produce very large numbers of small sperm because having large numbers increases the chances of a sperm being able to reach and fertilize the egg. It is easier to produce many sperm if they are small, since each individual cell takes up few resources.

Why are millions of sperms produced Class 8?

These sperms enter the female reproductive tract. Remaining sperms come in contact with the egg and only one of them may fuse with the ovum. This leads to fertilisation and hence the zygote is formed.

Why is a sperm cell so small?

Sperm are smaller than most cells in the body; in fact, the volume of a sperm cell is 85,000 times less than that of the female gamete. The head of the sperm contains the extremely compact nucleus with very little cytoplasm. These qualities contribute to the overall small size of the sperm (the head is only 5 μm long).
