Chemotaxis: role in egg-sperm interaction and its evaluation
Abstract: Communication between spermatozoa and egg before contact by chemotaxis is prevalent throughout the animal kingdom. In most animal species, the prospects of the spermatozoa coming in contact with eggs are very slim in the absence of some guidance mechanism usually chemical in nature that has been acquired gradually. Such chemical guidance, sperm chemotaxis, is now recognized in many marine invertebrates, fish, amphibians, and a few mammals including humans. This suggests …
