What are the steps to Fertilisation?
- 1. After insemination the sperm will move up the Fallopian tubes.
- 2. If ovulation has occurred and an egg is present the egg will release a chemical to attract the sperm.
- 3. The sperm that reaches the egg will use a digestive enzyme in its Acrosome to make an opening in the membrane of the egg.
- 4. Once one sperm enters the egg (only head enters), the egg forms a membrane that prevents other sperm from entering.
- 5. The nucleus of the egg fused with the nucleus of the sperm - a diploid zygote forms.
- 6. Fertilisation May take place during days 11-16 of menstrual cycle.
