Most sperm function tests analyze parts of the capacitation process, such as hyperactivation, sperm-zona binding, and acrosome reaction [7].
Spermatozoa also acquire vigorous swimming activity in the vicinity of the ova, the so-called hyperactivation phase, which is needed to traverse the zona pellucida after the acrosome reaction to fertilize the egg (Baldi et al.
