If two sperm penetrate an egg, a condition known as polyspermy occurs. This usually leads to an abnormal fertilization, resulting in an embryo with an incorrect number of chromosomes, which is typically not viable. In many organisms, mechanisms exist to prevent polyspermy, such as the fast block and slow block to polyspermy, to ensure normal development. If polyspermy does occur, it usually results in failed embryo development or miscarriage.

Why are many sperm ejected into the woman's body?
Males of every species have an ingrained need to keep their genes alive. The more sperm a male produces and the more eggs a female produces greatly increases the odds that a pregnancy will happen.
Is any part of a chicken egg sperm?
No, a chicken egg is not sperm. An egg is a female reproductive cell that is fertilized by a male sperm cell to form an embryo. In the case of a chicken egg, the yolk and the white are parts of the egg that provide nutrients and protection for the embryo to develop.
When sperm reach the oviduct there is no egg what happens to the sperm?
If there is no egg present in the oviduct when the sperm arrive, the sperm will typically die off and be naturally cleared from the body. They have a limited lifespan and cannot survive for long periods within the female reproductive system without encountering an egg for fertilization.
What animals begin as egg and sperm?
Almost all animals begin as an egg and a sperm. There are a few exceptions, though, such as sea sponges. But for the majority, they begin as sperm and egg.
What is sperm designed to do?
provide DNA to an egg to form an offspring
What is it called when the egg isn't penetrated by a sperm?
Fail!
What occurs when sperm cell unites with a egg cell?
When sperm reach an egg, there is a competition to get into the egg first. Since sperm travel in groups, theres a lot of competition. Once a sperm has penetrated the membrane, the membrane hardens, blocking the rest of the sperm out. Once inside, the sperm releases its genetic material, and the egg cell divides, and will continue so until a new baby is born.
Describe how you were able to tell by observation when a sea urchin egg was fertilized?
after an egg is penetrated by a sperm, the egg and sperm nuclei fuse to form a single nucleus. within 2- 5 minutes after sperm penetration, a fertilization membrane forms beneath the jell coat to prevent the entry of additional sperm.
When sperm reach oviduct there no egg there what happen to the sperm?
the sperm just die
What would happen if more than one sperm were able to fertilize an egg?
In humans, only one sperm can fertilize an egg to form a zygote. If more than one sperm were able to fertilize an egg, it would result in an abnormal number of chromosomes in the zygote, leading to developmental issues and likely miscarriage. This phenomenon is known as polyspermy and is usually prevented by mechanisms in the egg that block additional sperm from entering once one has already fertilized it.
What happen 2 sperm had entered the egg?
An egg only allows one sperm to enter and is fertilized by that one sperm: 2 cannot enter.
What would happen if two sperm cells join with two egg cells?
Two zygotes will be formed after fertilization.
What would happen if the sperm could not get into the egg?
If the sperm cannot get into the egg, fertilization cannot occur and pregnancy will not take place. The egg needs to be fertilized by the sperm in order for the genetic material from both to combine and form a zygote, which will eventually develop into an embryo.
What happen to sperm if one fallopian tube is blocked?
There are millions of sperm and they search everywhere for an egg. The sperm will die unless they fertelize an egg. So any way they will die.
What has to happen for the girl to get pregnant?
The sperm from the male has to meet with the egg from the female
What happen when a mature egg is not fertilized by sperm?
The egg is broken into pieces (disintegrates) and is discharged as menstrual flow
Find out how sperm and egg cells meet in cod?
The egg would do external fertilisation, so the female would let the egg out, and then the male would spray the sperm over it, and then the two would have a baby.
