The Processof Fertilization

By William Choi

The Sperm Journey

• Sperm begins its travels in the female’s vagina

• Then it moves through the cervix into the uterus

• Its last stop is in the fallopian tube

The Ovum Journey

• The ovum (egg) has been released from the ovary

• It has started to travel down the fallopian tube

• It is ready and waiting for the arrival of sperm so it can be fertilized

Sperm Meets Ovum

• Only one sperm will be allowed to enter

• The sperm which have made it to the egg try to penetrate its membrane (egg wall)

Sperm and Ovum Become One

• Sperm contains half of the genetic information to form a new life

• The ovum contains the other half of the genetic information

• The sperm cell releases its nucleus which combines with the egg's DNA to create a zygote

• A zygote is the first cell of a new life

Final Fertilization Step

• The zygote then travels down the fallopian tube into the uterus

• It attaches to the wall of uterus

• It resides there for the development of a baby
