• You can use the term "fertilization membrane" when discussing topics related to biology, reproduction, or animal and plant development.
• It’s a scientific term, so it is often used in educational settings or in conversations about reproductive science.

Example:

• "After the sperm successfully fertilizes the egg, a fertilization membrane develops to ensure that no other sperm can penetrate the egg."

Advanced Usage:
