Induction of acrosome reaction in human sperm by exposing to an electrical field.

The results of exposing the human sperm to an electrical field revealed that the percentage of sperm that lost their acrosome significantly increased with electrical pulse strength (p < 10(-6)), with 34.71 +/- 4.2, 47.16 +/- 6.9, and 58.13 +/- 5.7% of sperm undergoing the acrosome reaction when they were exposed to pulse strength of 750, 1000, and 1500 V/cm, respectively, in comparison with the control of 25.05 +/- 5.6%.
