Fertilisation is the process where an ovum and a sperm meet in one of the fallopian tubes. It has 5 steps:
1. Every 28 days an egg is released from one of the ovaries and is pushed along a fallopian tube towards the uterus.
2. Sperm enters the female reproductive system through the vagina and reaches the fallopian tube.
3. A sperm reaches the egg, gets inside it and fertilises it. At this moment a zygote is formed.
4. The zygote starts to divide and forms an embryo.
5. The embryo implants itself in the uterus, attaching itself to the wall, where there it continues to grow and develop.
