The Blood-Oocyte Barrier: Morphological Evidence Implicating The Zona Pellucida [PDF]
, 1991 A developing oocyte is capable of synthesizing non-self proteins recognized as foreign by the maternal immune system. Since the oocyte may be perceived as foreign it must be protected from interaction with the immune system in order for it to mature to

Structure and function of the zona pellucida: current state of knowledge [PDF]
, 2017 The mammalian zona pellucida is an extracellular matrix that surrounds the oocytes and embryos up until the stage of hatching of the blastocyst. It functions to facilitate sperm-oocyte binding by stimulating acrosome reaction and to protect the embryo ...

Zona pellucida mediated acrosome reaction and sperm morphology [PDF]
, 1997 Sperm samples from 29 men randomly selected from the andrology laboratory, were used to evaluate acrosome reaction response to solubilized human zona pellucida. Capacitated sperm samples were exposed to a solution containing 2 zona pellucidae (ZP) per μl

Isolation and Purification of Acrosin (ACR) from the Human Seminal Fluid of Infertility Patients
Medical Journal of BabylonBackground: Acrosin (ACR) is one of the most important proteases in the mammalian sperm head, located within the acrosome of human spermatozoa. ACR is a proteolytic enzyme that may hydrolyze the zona pellucida in oocytes.
