If no sperm is around to fertilize the egg, it moves through to the uterus and disintegrates. Your hormone levels go back to normal. Your body sheds the thick lining of the uterus, and your period starts. If one sperm does make its way into the fallopian tube and burrows into the egg, it fertilizes the egg.
Can you fertilize two different eggs?
In rare cases, two eggs can be fertilized at different times during two or more acts of sexual intercourse, resulting in fraternal twins with two different fathers, called bipaternization. Monozygotic, or identical twins, occur when one fertilized egg splits into two separate embryos.

Can you fertilize a human egg without sperm?
Scientists have devised a way to make human eggs behave as if they have been fertilised – without using sperm. The team from Wales College of Medicine at Cardiff University say this could provide a more ethically acceptable way of creating ’embryonic’ stem cells.

When can Roosters fertilize eggs?
Therefore, for fertile eggs, the first thing you will need is a rooster older than 5 months (about 20 weeks), as this is when they begin to become ready to fertilize a hen. Fertilizing leaves the hen with enough sperm to fertilize each egg she lays for a week or so.
How do eggs fertilized?
Fertilization occurs during the process of laying an egg. As an ovum moves down her oviduct and begins to form into an egg, the duck hen mixes in a little sperm from her sperm storage. The eggshell then forms around the ovum, yolk and sperm, and creates the egg we recognize.
