These are suitable conditions for sperm cell capacitation 10 and also to evaluate their ability to undergo acrosome reaction.
Reactive oxygen species requirements for bovine sperm capacitation and acrosome reaction.
CRISP2 protein that has been localized in the acrosome and sperm tail and involved in sperm-egg fusion, is a candidate gene in men infertility; however, analysis of CRISP2 variations in asthenozoo- and/or teratozoospermia failed to find a significant association (41).

In comprehensive view, it appears that the bulls with pattern 2 of exon 1+pattern 2 of exon 2+pattern 1 of exon 3 could be used as a marker for selecting higher sperm concentration, mass motility, live spermatozoa acrosome integrity and membrane integrity.

Moreover, they play the necessary role in sperm capacitation, acrosome reaction, and fertilization [18-21].
Results of the study, clearly indicate that osmotic stress primarily damaged the spermatozoa internal structures more severely (mitochondria, acrosome and DNA) rather than plasma membrane.
