The fertilization envelope is formed after sperm entry into the egg, triggering a series of events known as the cortical reaction. Upon fertilization, cortical granules in the egg release their contents into the space between the egg membrane and the vitelline layer, leading to modifications of the egg's extracellular matrix. This process hardens the outer layer and creates a protective barrier that prevents additional sperm from entering, thus ensuring that only one sperm fertilizes the egg. The formation of the fertilization envelope is crucial for preventing polyspermy and protecting the developing embryo.

What is the function of the fertilization envelope?
The fertilization envelope acts as a barrier that prevents polyspermy, which is when an egg is fertilized by more than one sperm. It also helps in the activation of the egg and plays a role in the early developmental processes of the embryo.
What is the fertilization envelope?
The fertilization envelope is a protective layer that forms around the egg after fertilization in many species, particularly in marine organisms like sea urchins and some amphibians. It is created by the exocytosis of cortical granules in the egg, which release substances that modify the egg's outer layer, preventing additional sperm from entering. This process helps ensure proper fertilization and contributes to the early development of the embryo by providing a stable environment. The fertilization envelope also plays a role in species-specific fertilization, ensuring that only sperm from the same species can successfully fertilize the egg.
