TL;DR: It is demonstrated that extracts of egg jelly contain factors that extend the period of sperm motility as well as providing a chemoattractant activity as previously reported, and that jelly-derived factors regulate both the longevity and directionality of sperm propulsion.
Journal ArticleDOI
Two types of assays for detecting frog sperm chemoattraction.
TL;DR: Sperm chemoattraction in invertebrates can be sufficiently robust that one can place a pipette containing the attractive peptide into a sperm suspension and microscopically visualize sperm accumulation around the pipette, and this type of assay is needed to demonstrate the orientation of sperm movement relative to the chemoattrractant gradient axis.
