Fertilization
The process in Simple Steps:
Step 1 - Many sperm travel from the Male testes to the Female Egg located in the Fallopian tube.]
Step 2 - Once the sperm reach the egg, many try and "enter" by releasing enzymes breaking down the outer layer of the egg.
Step 3 - Only one sperm can penetrate and once this happens, a chemical reaction occurs "pushing" away any other sperm attempting to penetrate.
This now fertilized egg is referred to as a zygote
Step 4 - pronuclei of the egg merges with the pronuclei of the sperm resulting in cell division.
Step 5 - days later this zygote is moved along the fallopian tube and is now called a blastocyst.
Step 6 - the blastocyst is embedded in the uterine wall activating the start of pregnancy.
