It is probably that there were not Ca〓 channel on the guinea pig sperm PM, because the Ca〓 channel blockers verapamil, nifedipine, diltiazem and D600 promoted acrosome reaction in synchronous and nonsynchronous cultural systems.

豚鼠精子质膜可能无Ca〓通道，因为verapamil、dilliazem和D600等对获能和未获能的精子的顶体反应均具有显著的促进作用。

Methods: The sperm morphology and sperm acrosin activity were analyzed by automated sperm morphology analyzer and spectrocolorimetry.

精子形态和顶体酶活性是决定精子能否受精的重要因素[1，2 ] 。
