Question

What happens when egg is fertilized ?

Answer 1

When an egg is fertilized by sperm in the fallopian tubes. Once fertilized, the cells start to multiply and grow. The zygote, or fertilized egg, travels down into the uterus and becomes what’s called a morula. In the uterus, the morula becomes a blastocyst and eventually burrows into the uterine lining in a process called implantation.

Answer 2

The fertilized egg stays in the fallopian tube for about 3 to 4 days. But within 24 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus.
