JordanOnce an ovum is fertilized by a sperm, it undergoes changes that prevent any other sperm from entering. This includes the release of enzymes that harden the outer layer of the ovum, called the zona pellucida, making it impermeable to additional sperm. This mechanism ensures that only one sperm can fertilize the egg, preventing polyspermy.
From HowStuffWorks, "Once a single sperm has penetrated the egg, the cell membrane of the egg changes its electrical characteristics. This electrical signal causes small sacs just beneath the membrane (cortical granules) to dump their contents into the space surrounding the egg. The contents swell, pushing the other sperm far away from the egg in a process called cortical reaction. The cortical reaction ensures that only one sperm fertilizes the egg. The other sperm die within 48 hours."

Can sperm penetrate clothing to reach the skin?
No, sperm cannot penetrate clothing to reach the skin.
Can sperm penetrate through underwear?
No, sperm cannot penetrate through underwear. Underwear acts as a barrier that prevents sperm from passing through.
Can sperm penetrate clothing and result in pregnancy?
No, sperm cannot penetrate clothing and result in pregnancy. Direct contact with the vagina is needed for sperm to fertilize an egg.
Can sperm penetrate clothing?
Yes, sperm can potentially penetrate clothing, but the likelihood of this happening depends on various factors such as the type of fabric, the amount of sperm, and the force of ejaculation.
When a sperm unites with an egg what is the fertilized egg?
When a sperm unites with an egg, the fertilized egg is called a zygote. This is the first stage of development in a new organism with a complete set of chromosomes from both the sperm and the egg.
Why can a second sperm not penetrate an already fertilized ovum?
Once a sperm penetrates the egg, changes occur on the membrane, effectively making it impenetrable to others. It is possible, however, for 2 sperms to penetrate at the same time, which could mess things up.
How does the sperm go about keeping the egg fertilized?
Sperm undergo a process called capacitation where they become more mobile and gain the ability to penetrate the egg. Once capacitated, sperm approach the egg and release enzymes that help break down the egg's outer layer, allowing a single sperm to penetrate and fertilize it. After fertilization, the egg undergoes changes that prevent other sperm from entering.
Where does the excess sperm go when the egg is already fertilized?
The excess sperm dies and it dissolves.
How Is Sperm Cell Fertalized?
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.
Can a egg be fertilized before menustration if there is sperm already present before menustration?
Yes it can.
Can sperm penetrate clothing to reach the skin?
No, sperm cannot penetrate clothing to reach the skin.
Can sperm penetrate through underwear?
No, sperm cannot penetrate through underwear. Underwear acts as a barrier that prevents sperm from passing through.
Can sperm penetrate clothing and result in pregnancy?
No, sperm cannot penetrate clothing and result in pregnancy. Direct contact with the vagina is needed for sperm to fertilize an egg.
Can sperm penetrate clothing?
Yes, sperm can potentially penetrate clothing, but the likelihood of this happening depends on various factors such as the type of fabric, the amount of sperm, and the force of ejaculation.
How is a human egg fertilized?
Sperm
What is immediately produced when an animal's egg cell is fertilized by the sperm?
Zygote is immediately produced when an animal's egg cell is fertilized by the sperm.
When a sperm unites with an egg what is the fertilized egg?
When a sperm unites with an egg, the fertilized egg is called a zygote. This is the first stage of development in a new organism with a complete set of chromosomes from both the sperm and the egg.
