The egg prevents more than one sperm from fertilizing it by disallowing the entry of any more sperms into the area near it. Firstly, a reaction...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your toug...
a motility of 75/70 (4) indicates that 75% of sperm were motile and 70% of sperm were progressively motile, moving rapidly across the microscopic field. Rapid progressivesperm motility generally is considered to be the most credible gauge of sperm motion for predicting the fertilizing capacity ...

results from elimination of sperm through an unknown mechanism at the end of spermatogenesis (prior to transfer to seminal vesicles) and that sperm are inefficient at fertilizing eggs and cannot support embryo development. Our findings provide a foundation for future studies inDrosophila melanogasterto ...

diseases. Finally, understanding how sperm are modified to cope with potential hazards, interact with the female, and fertilize eggs is important for understanding the biology of many internally fertilizing organisms, including livestock and humans. Our description ofAe. aegyptireproduction may provide ...
Since spermatozoa are terminally differentiated cells and lack the ability to synthesize new proteins, proteomic analysis may help to determine their accurate fertilizing ability. Therefore, proteomics approach has been widely accepted as the primary choice for identifying fertility biomarkers in sperm and ...
Introduction Fertilization is a complex multi-stage process. After ejaculation, a maturation process, called capacitation, sets in, whereby sperm become motile and acquire the ability to locate and fertilize the egg. During capacitation, sperm adopt a whiplash-like flagellar beat pattern, called hype...
