Biomolecular research proves that with the additional of several seminal plasma proteins can improve the fertilization process, cell survival and has a positive role to the process of spermatozoa capacitation and acrosomal reaction [4].
Only capacitated cells can undergo acrosomal reaction, a vital step that aids the cell to penetrate the ova to achieve fertilization.

Then spermatozoa adhere to the oocytes zona pellucida to induce the acrosomal reaction, in which the fusion of the spermatozoal plasma membrane and the outer acrosomal membrane occurs to allow the acrosomal enzymes to be released.
ZP not only plays a crucial role in fertilization by serving as a species-selective substrate for sperm binding but also acts as an agonist for regulated exocytosis of the spermatozoon's acrosomal vesicle (1).
