"In all mammalian species examined, capacitation requires removal of cholesterol from the plasma membrane and the presence of extracellular Ca(++) and HCO3(-). protein tyrosine phosphorylation, a hallmark of capacitation in other species' sperm, occurs during five hours of in vitro incubation and that this phosphorylation is dependent upon HCO3(-), Ca(++), and the removal of cholesterol from the membrane." . .
