Morphology

fertilization + membrane

This is a straightforward noun–noun compound: combining 'fertilization' (the fusion of egg and sperm) with 'membrane' (a thin layer) yields a membrane associated with fertilization. The meaning (a membrane forming around a fertilized ovum) is directly compositional and follows common cross-linguistic compound logic, so a learner who knows both constituents can infer the MWE's basic sense.

Etymology

Fertilization membrane: The noun fertilization membrane names the thin layer that forms around an egg right after one sperm enters. Think of fertilization as the joining of sperm and egg and of membrane as a thin 'wall' that closes the egg to stop other sperm, which is why the phrase means a layer that prevents additional sperm from entering.
