Conclusion: The role of seminal free L-carnitine in the maintenance of normal functional spermatozoal
characteristics was validated.
Sperm concentration, motility and morphology have been correlated with fertilization rates in vivo and in vitro (2, 26), as a result of normal development of spermatozoal
subcellular structures during spermatogenesis in the testes, normal epididymal maturation and normal seminal plasma constituents (2).
Testosterone secretion and pharmacological spermatozoal
recovery in the cane toad (Bufo marinus).
It has previously been suggested that damaged spermatozoal
cells can be phagocytosed (Sutovsky et al.
Phylogeny of the Brachyura with particular reference to the Podotremata: evidence from a review of spermatozoal
ultrastructure (Crustacea, Decapoda).
It was reported that RJ might maintain the acrosomal integrity as its composition is highly variable containing hormones which decrease oxygen radicals and therefore reducing the number of molecules needed to be scavenged by the superoxide dismutase enzyme which were present normal in seminal plasma to counteract the effects of ROS on lipid peroxidation and prevent spermatozoal
Selenium supplementation enhances the element concentration in blood and seminal fluid but does not change the spermatozoal
quality characteristics in subfertile men.
Effect of storange temperature, cooling rates and two different semen extenders on canine spermatozoal
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.
Expression of mammalian spermatozoal
Increased nitric oxide also has been demonstrated in the spermatic veins of patients with varicocoele (72,73), which could be responsible for the spermatozoal
This preliminary observation is supported by the detection of multiple spermatozoal
proteins, more specifically between 21.
