Question

What happens when the egg is not fertilised?

Answer 1

When the egg is not fertilized, it is shredded off from the body and menstrual cycle takes place. Ovary releases one egg every month. At the same time, the uterus also prepares itself to receive a fertilized egg. The endometrium lining becomes thick and spongy for carrying embryo. It would also nourish the embryo if had fertilization taken place. IF the egg is not fertilized, this lining breaks. This results in the discharge of blood and mucous through vagina. This menstrual cycle last for around 5 to 7 days until all the debris of endometrium along with blood is discharged.
