Okabe M, Cummins JM Mechanisms of sperm-egg interactions emerging from gene-manipulated animals. A cross-over experimental design was used to segregate effects on early stages of capacitation, spanning the first 5 h of incubation, from those on acrosome reactions and zona penetration during the last 1 h. Annu Rev Cell Dev Biol — Notably, membrane fusion occurring intercellularly between a sperm and an egg is essential for fertilization. Zona penetration and hyperactivation were highly correlated. Considerable efforts are being devoted to understanding the molecular basis of cell-cell fusion; however, the exact mechanism s of the fusion process remain unclear.

Couzin J Cell biology: the ins and outs of exosomes. Zona penetration and hyperactivation were highly correlated. Abstract The bicarbonate: CO2 HCOCO2 concentration dependencies of hamster sperm motility, spontaneous acrosome reactions, and zona penetration used to assay the zona-induced acrosome reaction were examined.
