Question

What changes are observed in the uterus if fertilization does not take place?

Answer 1

Fertilization:

The process of fusion of haploid gametes is called fertilization. It occurs only in sexually reproducing organisms.

Changes in the uterus if fertilization does not occur:

1. The uterus prepares itself by increasing the thickness of the endometrium layer and blood vessels to nourish the baby.
2. However, when the egg does not fertilize, the uterus slowly breaks along the endometrium lining and bleeds through the vagina. This process is called menstruation.
