What is fertilization membrane? How it is formed?

Text Solution

Verified by Experts

The membrane formed by the contents of cortical granules of egg in the perivitelline space is called fertilization membrane. It prevents the polyspermy condition in human beings. The cortex has a number of granules that rupture and release their contents. The contents released at the vitelline membrane become applied to the inner surface of the vitelline membrane which is very thick. This thickened membrane is called fertilization membrane.
