Explain what happens to the zona pellucida after the egg is fertilised

write it in your own words:

"In humans, five days after the fertilization, the blastocyst performs zona hatching; the zona pellucida degenerates and decomposes, to be replaced by the underlying layer of trophoblastic cells. The zona pellucida is essential for oocyte growth and fertilization."

The zona pellucida supports communication between oocytes and follicle cells during oogenesis; protects oocytes, eggs, and embryos during development, and regulates interactions between ovulated eggs and free-swimming sperm during and following fertilization.

The blastocyst achieves zona hatching. The zona pellucida deteriorates and disintegrates, waiting for its replacement by the underlying layer of trophoblastic cells.

Once a sperm enters the zona pellucida, it connects and combines with the plasma membrane of the oocyte. Union occurs at the back region of the sperm head. The molecular characteristics of sperm-oocyte binding are not entirely resolved.
