Almost there! If you are tired you can stay here for a bit!
The sperm enters the cervix hoping to find the correct passageway to the uterus.
Once the sperm takes the correct passageway to the uterus it has some obstacles like the white blood cells where most of the sperm don't survive.
Finding a room in the castle!
In the Fallopian tubes the sperm can stay there for weeks and even a month because your body regulates the temperature so that the sperm can survive until ovulation where if it's lucky it will meet its egg.
Once the sperm and egg meet the sperm fertilizes the egg which creates cells that turn into a baby.
After the egg is fertilized it finds its resting place in the uterus where 5 days later it will begin growing.
