Examples
The phenomenon echoes a previous finding that spermatozoa under DGC are more capacitated and respond more to acrosome reaction than with other methods.
The acrosome reaction does not occur spontaneously following in vitro capacitation unless stimulated, and when this response takes place it most likely the result of cell deterioration.
