Choline- an essential nutrient that is related to the B vitamins
This enzyme is finally converted to a cross-linked structural protein, comprising a significant component of the mitochondrial sheath of mature spermatozoa ( Figure 1 Hyperactivation is a sperm motility pattern characterized by an extremely vigorous whiplash-like flagellar beating, which enhances the ability of the sperm to penetrate the cumulus cell layer surrounding the oocyte ( has been shown to be crucial not only for the initiation, but also the preservation of the hyperactivated state ( 2 O 2 ( Capacitation is a crucial physiological process of sperm maturation occurs during its passage through the female reproductive tract to enable sperm-oocyte interaction ( In contrast to sperm capacitation, acrosome reaction is an irreversible process which involves the release of acrosomal hydrolytic enzymes to attain sperm oocyte fusion ( In vivo , the sperm-zona pellucida binding triggers a cascade of signal transduction reactions that culminates in an significant increase in intracellular Ca 2+ levels required for acrosomal exocytosis ( and H 2 O 2 within physiological limits is essential to elicit acrosome reaction through the activation of tyrosine phosphorylation of potential target proteins particularly on the pre-equatorial region of the sperm head surface ( 2+ influx and the activation of adenylate cyclase and cAMP as well as the phosphorylation of reasonably similar target substrates ( Pathological Effects of ROS on Spermatozoa Remarkably increased ROS levels have been detected in 2540% of semen samples of infertile patients (Figure 1B), including proteins, lipids and nucleic acids, which ultimately hampers multiple cellular functions ( Sperm plasma membrane contains larger amounts of PUFAs, particularly docosahexaenoic acids, which are required to maintain optimal fluidity essential for multiple membrane fusion events
