Fertilization Process

Written by Lone Parenting Advisor

Fertilization happens basically when the sperm enters the uterus and penetrates the fertile egg (ovum).

The egg (ovum) then mixes with the sperm (causing the sperm tail and body to come away) and together they become the nuclei after penetration and start the fertilization process.

The fertilized egg (ovum) is now called a zygote which surrounds itself with an outer protective layer that other sperm cannot penetrate. The zygote passes through the fallopian tubes until it reaches the uterus, during its journey it is constantly dividing cells as it travels.

The zygote transforms into the morula which is a solid ball of cells and starts to change. The morula divides within itself and puts aside a cluster of cells known as a blastocyst.

The blastocyst embeds itself into the uterus wall and starts to mature into an Embryo also forming the placenta.
