“…Therefore, we can reasonably hypothesize that one of the most important mechanisms by which the addition of GSH increases fertility and prolificacy of frozen‐thawed spermatozoa is the protection of the nucleoprotein structure and subsequent DNA integrity. In this regard, it is worth noting that previous reports have emphasized the relevance of chromatin integrity on sperm fertilizing ability (Silva & Gadella, ), and that the oviductal selection mechanisms in the establishment of sperm reservoir, so important in eutherian mammals (Yeste, ), have been reported to be endowed with stable and non‐fragmented chromatin structure (Ardón et al ., ). All of these data appear to highlight the importance of a correct nucleoprotein structure to explain boar sperm fertilizing ability.…”

“…The sperm reservoir in the oviduct plays a crucial role following natural mating and artificial insemination with liquid‐stored semen (reviewed in Yeste, ). However, frozen‐thawed sperm are not able to form an effective sperm reservoir due to the destabilization of the sperm membrane and capacitation‐like changes that occur during freeze‐thawing, which decrease the ability of sperm to bind to oviductal epithelial cells (Abad, Sprecher, Ross, Friendship, & Kirkwood, ).…”

“…Fertilization is a complex process in which sperms recognize and pass through the zona pellucida of mature oocytes, fuse with the oocyte membrane, and activate oocytes. 19 Mature oocytes contain many maternal genes regulating fertilization, in which Piga and Cd9 are known to be involved in sperm–oocyte fusion. 20 , 21 Changes in ion channels and transporters during oocyte maturation give mature oocytes the ability to support fertilization.…”
